Oil Free by 2050

Wednesday, February 28th, 2007

Hornet-over-oil-wells.jpg

The US mil­i­tary needs oil — about 300,000 bar­rels a day — to fight.

Lots of oil comes from the same places where the mil­i­tary actu­ally is fight­ing today, or may be fight­ing some­time in the not so dis­tant future. (Hello, Iran?)

Oh, the irony!

It should come as no sur­prise then that the Department of Defense is giv­ing very seri­ous thought to oil inde­pen­dence. The notion is that the nation — and par­tic­u­larly the mil­i­tary — must have assured access to energy, and oil isn’t such a safe bet any more.

Champions of this con­cept are known to include John Young, DOD’s direc­tor for Defense Research and Engineering; and Ron Sega, under­sec­re­tary of the Air Force and — on Capitol Hill — New York Republican Representative Steve Israel and Maryland Republican Representative Roscoe Bartlett.

There’s been some press about a highly-​​touted Air Force exper­i­ment using a syn­then­tic base fuel (derived from nat­ural gas pumped in from Oklahoma) to power one of the B-52’s eight engines.

But that’s just kid-​​stuff, really.

It’s very clear that a much broader vision exists within DOD to really go … all .. the … way, and fast.

The vision can be found in this master’s the­sis by Air Force Lt Col Michael J. Hornitschek, who orig­i­nally pub­lished the doc­u­ment for the Air University’s Center for Strategy and Technology. It has since been repub­lished in the Air Force Journal of Logistics. It’s a the­sis, but it often reads like a very good Popular Science arti­cle.

Here’s a quick excerpt that explains the vision:

“A directed-​​energy based, highly-​​automated force, capa­ble of gen­er­at­ing a major­ity of its own power in a dis­trib­uted fash­ion from local and envi­ron­men­tal sources, could the­o­ret­i­cally pro­vide that future. The poten­tial effi­ciency, envi­ron­men­tal ubiq­uity, uni­ver­sal­ity and con­vert­ibil­ity from one form to another of this con­fig­u­ra­tion, make strong argu­ments that the force of 2050 can be pow­ered almost exclu­sively by elec­tric­ity and hydrogen.

“Setting aside con­ven­tional par­a­digms allows one to imag­ine a con­cep­tual 2050 force. All navy ships might employ nuclear-​​powered direct-​​electric dri­ves, light­weight nano­engi­neered hulls, and directed energy arma­ment. All army and marine corps future com­bat sys­tem land vehi­cles (many of which are unmanned) are designed for mod­u­lar upgrades with plug-​​in elec­tric hybrid or fuel-​​cell power, light­weight car­bon nanotube-​​based armor and directed energy weaponry. Today’s vul­ner­a­ble tanker fuel trucks are replaced with smaller hybrid or fuel-​​cell pow­ered trucks car­ry­ing sta­ble, solid hydrate-​​based hydro­gen bat­ter­ies or com­bat safety-​​engineered liq­uid hydro­gen con­tain­ers. Individual sol­diers are out­fit­ted with pocket hydro­gen fuel cells to power 10–15 onboard elec­tric sys­tems. Virtually all com­bat fighter air­craft are small, unmanned or single-​​seat, and pow­ered by liq­uid or even nano-​​engineered solid hydrogen-​​based fuels. Ultra-​​efficient air­craft designs elim­i­nate the need for tanker air­craft. All imagery (sic), sur­veil­lance and recon­nais­sance (ISR) plat­forms are either space-​​based or unmanned vehi­cles, orbit­ing for weeks at a time exclu­sively on solar-​​generated power while peer­ing through weather from above.”

WALL_STREET.jpg

NEW YORK (AP) — Defense stocks tum­bled Tuesday, dragged down by fears of a weak­en­ing global econ­omy that sent the Dow Jones Industrial Average down by more than 3 percent.

The defense sec­tor sell­off afflicted Bethesda, Md.-based Lockheed Martin Corp., Los Angeles-​​based Northrop Grumman Corp., Falls Church, Va.-based General Dynamics Corp. and Providence, R.I.-based Textron Inc.

U.S. stock mar­kets headed lower after a 9 per­cent slide in Chinese stocks, with the Dow briefly falling by more than 500 points before rebound­ing some­what later in the day. The last time the Dow dropped more than 500 points was on Sept. 11, 2001.

Lockheed gained 4 cents to $97.61 in after­mar­ket trad­ing, after drop­ping $3.55, or 3.5 per­cent, to close at $97.57 on the New York Stock Exchange. Shares traded between $69.87 to $103.50 over the last 52-​​week period.

Shares of Northrop gained 13 cents to $72.04 in after­mar­ket trad­ing, after drop­ping $1.93, or 2.6 per­cent, to $71.91. Shares traded between $61.51 to $75.72 over the last 52-​​week period.

Textron shares gained 8 cents to $90.91 in after­mar­ket trad­ing, after dip­ping $4.33, or 4.5 per­cent, to close at $90.83 on the Exchange. Shares traded between $80.46 to $98.96 over the last 52-​​week period.

Shares of General Dynamics dropped $2.76, or 3.5 per­cent, to close at $75.33 on the NYSE. The com­pany traded between $61.20 and $81.28 over the last 52-​​week period.

God Slides Shuttle Launch to the Right

Tuesday, February 27th, 2007

shuttle.dings.jpg

KENNEDY SPACE CENTER, Florida (CNN) — A sched­uled March 15 launch has been delayed after the exter­nal fuel tank attached to the shut­tle Atlantis and pos­si­bly the orbiter itself were dam­aged by a hail­storm at the launch pad Monday afternoon.

NASA mete­o­rol­o­gists say wind gusts of 62 miles per hour and golf-​​ball-​​size hail were observed at pad 39A, where Atlantis was under­go­ing final prepa­ra­tions for launch.

Workers at the Kennedy Space Center in Florida are still assess­ing the extent of the dam­age, but NASA man­agers decided Atlantis must be rolled back to the Vehicle Assembly Building for thor­ough inspec­tions and repairs.

The roll­back means Atlantis will not launch in March as planned. Program offi­cials hope repairs can be com­pleted for a launch in late April or May.

That Deaf, Dumb, and Blind Jet …

Tuesday, February 27th, 2007

Tommy.jpg

A recent transpac crip­pled six F-​​22s as they made their way from Hawaii to Kadena Air Base in Okinawa, Japan. The cul­prit: The International Date Line.

When the fight­ers crossed the line, all of their com­puter sys­tems went Tango Uniform — fuel sub­sys­tems, nav­i­ga­tion, and some of the comms.

We turn to CNN’s John Roberts and retired Maj. Gen. Don Shepperd for expert com­men­tary on the matter:

ROBERTS: Twenty five years from devel­op­ment to deploy­ment, the F-​​22 Raptor is the most advanced fight­ing machine in the air. But it was no match for a com­puter glitch that left six of them high above the Pacific Ocean, deaf, dumb and blind as they headed to their first deploy­ment. So what hap­pened? We turn to a man who’s at home in the cock­pit, Retired Air Force Major General Don Shepperd. Don, let me set the scene. These F-​​22s, eight of them, were headed from Hickam Air Force base in Hawaii to an Air Force base in Japan. They were approach­ing the inter­na­tional date line, pick it up from there. 

F22s.jpg

SHEPPERD: You got it right, John. You want every­thing to go right with your front­line fighter, $125, $135 mil­lion to copy. The F-​​22 Raptor is our front­line fighter, air defense, air supe­ri­or­ity. It also can drop bombs. It is stealthy. It’s fast and you want it all to go right on your first deploy­ment to the Pacific and it didn’t. At the inter­na­tional date line, whoops, all sys­tems dumped and when I say all sys­tems, I mean all sys­tems, their nav­i­ga­tion, part of their com­mu­ni­ca­tions, their fuel sys­tems. They were — they could have been in real trou­ble. They were with their tankers. The tankers — they tried to reset their sys­tems, couldn’t get them reset. The tankers brought them back to Hawaii. This could have been real seri­ous. It cer­tainly could have been real seri­ous if the weather had been bad. It turned out OK. It was fixed in 48 hours. It was a com­puter glitch in the mil­lions of lines of code, some­body made an error in a cou­ple lines of the code and every­thing goes.

ROBERTS: This is almost like the feared Y2K prob­lem that hap­pened to these air­craft. We should point out that com­put­ers con­trol almost every aspect of this air­craft, from their weapons sys­tems, to the flight con­trols and the com­put­ers absolutely went hay­wire, became useless.

SHEPPERD: Absolutely. When you think of air­planes from the old days, with cables and that type of thing and direct con­nec­tions between the sticks and the yolks and the con­trols, not that way any­more. Everything is by com­puter. When your com­put­ers go, your air­planes go. You have mul­ti­ple sys­tems. When they all dump at the same time, you can be in real trou­ble. Luckily this turned out OK.

ROBERTS: What would have hap­pened General Shepperd if these brand-​​new $120 mil­lion F-​​22s had been going into battle?

SHEPPERD: You would have been in real trou­ble in the mid­dle of com­bat. The good thing is that we found this out. Any time — before, you know, before we get into com­bat with an air­plane like this. Any time you intro­duce a new air­plane, you are going to find glitches and you are going to find things that go wrong. It hap­pens in our civil­ian air­lin­ers. You just don’t hear much about it but these things absolutely hap­pen. And luck­ily this time we found out about it before com­bat. We got it fixed with tiger teams in about 48 hours and the air­planes were fly­ing again, com­pleted their deploy­ment. But this could have been real seri­ous in combat.

ROBERTS: So basi­cally you had these advanced air — not just supe­ri­or­ity but air supremacy fight­ers that were in there, up there in the air, above the Pacific Ocean, not much more sophis­ti­cated than a lit­tle Cessna 152 only with a jet engine.

SHEPPERD: You got it. They are on a 12 to 15-​​hour flight from Hawaii to Okinawa, but all their sys­tems dumped. They needed help. Had they got­ten sep­a­rated from their tankers or had the weather been bad, they had no atti­tude ref­er­ence. They had no com­mu­ni­ca­tions or nav­i­ga­tion. They would have turned around and prob­a­bly could have found the Hawaiian Islands. But if the weather had been bad on approach, there could have been real trou­ble. Again, you get refu­el­ing from your tankers. You don’t run — you don’t get your­self where you run out of fuel. You always have enough fuel and refu­el­ing nine, 10, 11, 12 times on a flight like this where you can get some­where to land. But again, atti­tude ref­er­ence and nav­i­ga­tion are essen­tial as is com­mu­ni­ca­tion. In this case all of that was affected. It was a seri­ous problem.

ROBERTS: So the fact the com­put­ers run so much of the sys­tems on these air­craft, General Shepperd, is the — is the mil­i­tary at risk of over engi­neer­ing here so if they did have a prob­lem like that when they were going into a hos­tile sit­u­a­tion, they could be, as you said, repeat­edly in real trouble?

SHEPPERD: Well, you have redun­dant sys­tems but it’s just a fact of life in the mod­ern com­puter age. By the way John, you are going to have the same prob­lem com­ing up on your lap­top com­puter as we con­ferred from — from stan­dard time from day­light sav­ings time to stan­dard time. Your pro­gram — your com­puter is pro­grammed for one thing and we have changed the dates and you are going to have a prob­lem. It’s going to have to be dealt with.

ROBERTS: Do me a favor Don. Make sure I’m not on my lap­top com­puter when I’m fly­ing in an F-​​22 on that day.

SHEPPERD: Absolutely.

And make sure you don’t try to con­duct any strikes across the International Date Line. One side or the other, war plan­ners; one side or the other.

Obsessed with Vertical Lift?

Tuesday, February 27th, 2007

JSF stovl.jpg

The short-​​takeoff-​​and-​​vertical-​​landing (STOVL) F-​​35B is either what makes the Joint Strike Fighter (JSF) pro­gram the stuff of genius — or a sure bet for failure.

Think about it.

With the F-​​35B, the JSF pro­gram lays claim to an unprece­dented aero­dy­namic hat trick: one com­mon fighter design/​three very, very dif­fer­ent ways to take off and land. On the other hand, the F-​​35B is the biggest headache to develop and is already the lead­ing cause for a two-​​year-​​delay and $5 bil­lion cost over­run. And the air­craft still has yet to fly.

The F-​​35B also hap­pens to be the diplo­matic glue that attracts an inter­na­tional part­ner­ship to chip in one-​​tenth of the JSF’s devel­op­ment cost. Only two of the eight JSF part­ners want the STOVL air­craft, but one of those is the UK. And if the JSF pro­gram loses the UK, you may say good­bye to the rest of the inter­na­tional part­ners and hello to Eurofighter Typhoon Tranche 3. (Without inter­na­tional cover, the JSF also may look a lot more invit­ing to the increas­ingly rapa­cious budget-​​cutters in the Pentagon.)

So let’s hope the F-35B’s largest cus­tomer — the US Marine Corps — knows what it’s doing.

It is in this con­text that I was so inter­ested to read the new book, Harrier II: Validating V/​STOL, by Lon O. Nordeen. Perhaps, by under­stand­ing why the USMC believes the Harrier — and the F-​​35B — are so nec­es­sary, we may under­stand the dis­porpor­tion­ate influ­ence it wields over the JSF program.

AV8.jpg

First, it has to be under­stood that, historically-​​speaking, V/​STOL is an aero­dy­namic fetish. To under­stand this point, please check out the aptly-​​titled V/​STOL Wheel of Misfortune. Of the 45 V/​STOL projects attempted in his­tory, only four — the Harrier, the V-​​22, the CL-​​84, and F-​​35B –ven­tured much beyond the pro­to­type stage. Three of them involve the Marines.

In his book, Nordeen unfor­tu­nately chooses not to ana­lyze or com­ment but to straight­for­wardly present the USMC’s obses­sion with the Harrier as a prod­uct of Vietnam. Close air sup­port seemed to be quite a topic of dis­cus­sion (imag­ine that?) at the time. To deal with the issue, the Air Force wanted to buy the A-​​10, the Army favored the Lockheed AH-​​56A Cheyenne and the USMC focused on the AV-​​8A Harrier. Asked by Congress to pick the best option, DOD (sur­prise!) backed all three. (The Cheyenne was later cancelled.)

It’s clear from Nordeen’s writ­ing that the USMC likes V/​STOL because of the obvi­ous: its fight­ers don’t need a long run­way or an air­craft car­rier to take off. In the Falklands War, Royal Air Force GR Mk. 3 Harriers arrived — and oper­ated — in the South Atlantic war zone on board the con­tainer ship Atlantic Conveyor (until the ship was struck by an Argentine exo­cet mis­sile). Such bas­ing flex­i­bil­ity briefly appealed to the US Air Force, which in 2004 and 2005 flirted with the idea of buy­ing a bunch of F-​​35Bs.

Whether that flex­i­bil­ity is really worth the price in reduced aero­dy­namic per­for­mance and increased main­te­nance bur­den is unfor­tu­nately not within the scope of Nordeen’s book. Even within his cho­sen lim­its, how­ever, it is neg­li­gent as a his­to­rian for him to omit any ref­er­ence to the Harrier’s trag­i­cally hor­ren­dous safety record.

While the V/​STOL Harrier fleet were a potent force in the Falklands con­flict, the advan­tage of bas­ing flex­i­bil­ity alone hasn’t proved piv­otal in any mod­ern engage­ment since. It is impres­sive to think of the devo­tion the Marines lav­ish on this one aero­dy­namic qual­ity, per­haps to the detri­ment of all else.

Danes Join JSF Effort

Tuesday, February 27th, 2007

JSF.jpg

(COPENHAGEN, Denmark, Feb 27, 2007 /​PRNewswire) — Denmark today became the ninth and final F-​​35 part­ner nation to join the pro­duc­tion and sup­port phase of the Joint Strike Fighter program.

In sign­ing the F-​​35 Production, Sustainment and Follow-​​On Development Memorandum of Understanding, Denmark extends its coop­er­a­tion in the pro­gram beyond the cur­rent System Development and Demonstration (SDD) phase, and joins the fam­ily of part­ner nations that will coop­er­a­tively develop, pro­duce, test, train and oper­ate the F-​​35 Lightning II.

“Today’s mile­stone is not the end of a process but rather the begin­ning of con­struct­ing the world’s great­est air­power coali­tion,” said Brig. Gen. C.R. Davis, F-​​35 Lightning II pro­gram exec­u­tive offi­cer. “Denmark’s long his­tory of active part­ner­ship with the U.S. and all F-​​35 part­ner nations reaches a new pin­na­cle today as the coun­try signs this MOU. This is a really great moment for the entire F-​​35 Lightning II Team.”

Denmark’s work on the pro­gram includes advanced com­pos­ites, com­mu­ni­ca­tions soft­ware, control-​​surface com­po­nents and weapons pylons.

“Lockheed Martin is proud to con­tinue its long­stand­ing alliance with Danish indus­try, which has repeat­edly shown that it is fully com­pet­i­tive with the best in the world,” said Tom Burbage, Lockheed Martin exec­u­tive vice pres­i­dent and gen­eral man­ager of F-​​35 Program Integration. “This is a day to cel­e­brate the strong rela­tion­ship between Denmark and the United States, and to rec­og­nize the Danish gov­ern­ment, mil­i­tary and indus­try for their fore­sight and dedication.”

Denmark joined the JSF pro­gram in 1997, and in 2002 was the first European nation to enter the program’s SDD phase. Over the last four months, the United States and the other JSF part­ner nations — the United Kingdom, Italy, the Netherlands, Turkey, Canada, Australia and Norway — signed the F-​​35 pro­duc­tion and sus­tain­ment memorandum.

The Lightning II is a stealthy, super­sonic, multi-​​role, 5TH Generation jet designed to replace a wide range of exist­ing air­craft, includ­ing AV-​​8B Harriers, A-​​10s, F-​​16s, F/​A-​​18 Hornets and United Kingdom Harrier GR.7s and Sea Harriers. The first F-​​35 began its flight test pro­gram on Dec. 15, 2006.

Lockheed Martinis devel­op­ing the F-​​35 Lightning II with its prin­ci­pal indus­trial part­ners, Northrop Grumman and BAE Systems, along with a world­wide sup­plier net­work. Two sep­a­rate, inter­change­able F-​​35 engines are under devel­op­ment: the Pratt & Whitney F135 and the GE Rolls-​​Royce Fighter Engine Team F136, with either engine pro­duc­ing 40,000 pounds of thrust.

CSAR-​​X Protest Upheld

Tuesday, February 27th, 2007

h-47.jpg

Boeing Co.‘s $15 bil­lion con­tract to build U.S. Air Force res­cue heli­copters should be put back out to bid, the Government Accountability Office said fol­low­ing protests by Lockheed Martin Corp. and United Technologies Corp.

The GAO said today in an e-​​mailed state­ment it rec­om­mended the Air Force reopen dis­cus­sions and request revised pro­pos­als. If after review­ing the new bids, “Boeing’s pro­posal no longer rep­re­sents the best value to the gov­ern­ment, the agency should ter­mi­nate its con­tract,” the GAO said.

Lockheed Martin, the world’s largest defense com­pany, and United Technologies’ Sikorsky unit protested Boeing’s Nov. 9 award, say­ing the Air Force didn’t uni­formly apply the cri­te­ria used to eval­u­ate the three bids. Boeing’s order for 141 HH-​​47 heli­copters, a vari­ant of its twin-​​rotor Chinook fam­ily, was picked to replace Sikorsky’s Pave Hawk air­craft. The award was put on hold dur­ing the GAO review.

Fun for Feds and Fathers (and Delta Force)

Not only is this tech in play in the GWOT, with prom sea­son rapidly approach­ing, it also looks like a manda­tory sys­tem for sub­ur­ban house­holds across the heartland.

This from the manufacturer’s site:

“The Track Stick receives sig­nals from twenty four satel­lites orbit­ing the earth. With this infor­ma­tion, the Track Stick can pre­cisely cal­cu­late its own posi­tion any­where on the planet to within fif­teen meters.

“The Track Stick will work any­where on the planet Earth. Using the lat­est in GPS map­ping tech­nolo­gies, your exact loca­tion can be shown on graph­i­cal maps and 3D satel­lite images.

“The Track Stick’s micro com­puter con­tains spe­cial math­e­mat­i­cal algo­rithms, that can cal­cu­late how long you have been indoors. While vis­it­ing fam­ily, friends or even shop­ping, the Track Stick can accu­rately time and map each and every place you have been.”

trackstick-ad.jpg

Yes. That’s why I need this device. Often I wake up and won­der, “Gee, where have I been and how long was I indoors before I wound up face­down on my neighbor’s lawn?”

The company’s web­site does men­tion an “oh, by the way” at the bot­tom of the home­page: “It is ille­gal to track some­one with­out their {sic} permission.”

Do our spe­cial forces and the CIA know that? They cer­tainly don’t want to get them­selves into any more hot water.

It’s a (Future) Gas, Gas, Gas

Saturday, February 24th, 2007

F22-tanking.jpg

The US Air Force has just issued a rather innocuous-​​looking notice for a new tech­nol­ogy called “active com­bus­tion con­trol.” But this is quite a momen­tous devel­op­ment, and here’s why.

Today, the Air Force has two kinds of war­planes that can sur­vive in com­bat in which fight­ers and bombers have to com­pete with inte­grated air defenses as well as increas­ingly sophis­ti­cated enemy fighters.

One is the Northrop Grumman B-​​2A bomber. It’s rel­a­tively slow, but super-​​stealthy. It can fly for a long time and drop a lot of weapons.

The other is the Lockheed Martin F-​​22A. It’s extremely fast and also super-​​stealthy. But it doesn’t fly for very long with­out refu­el­ing and can carry only a cou­ple of strike weapons (okay, eight if your talk­ing about the Small Diameter Bomb).

The miss­ing link is a sin­gle air­craft as nim­ble as the F-​​22, as long-​​range as the B-​​2 and as at least as stealthy as both. In short, it’s the dream war­plane for every gadget-​​hearting Air Force general.

This meld­ing is the basic con­cept for what the Air Force now calls the “Next Generation Long Range Strike Aircraft.” It’s sup­posed to be ready to enter ser­vice by 2018 to 2020.

The trick to meet­ing this sched­ule is for some com­pany to come up with the next break­through in air­craft engine tech­nol­ogy. The break­through is called “active com­bus­tion con­trol,” which is just a fancy name for inte­grat­ing a fuel injec­tor into an aircraft’s propul­sion system.

Aircraft engines using active com­bus­tion con­trols should be able to fly longer dis­tances at a lower rate of fuel consumption.

With today’s engine tech­nol­ogy, the flow of gas into the com­bus­tion cham­ber is fairly unre­stricted, which is not very effi­cient. Many years ago, the auto­mo­tive indus­try fixed this prob­lem with fuel injec­tors, and now the aero­space indus­try wants to make a sim­i­lar leap — although at a far greater level of sophis­ti­ca­tion, of course.

It’s a new spin on an old con­cept. In the past, air­craft design­ers used variable-​​geometry wings (think: F-​​111, F-​​14, and B-​​1) to be more effi­cient in high-​​speed and cruise-​​speed. With active com­bus­tion con­trols, the goal is to recon­fig­ure the engine instead of the air­frame to be opti­mal in both states.
