How TARDEC's military research advances automotive technology

At the Tank Automotive Research Development and Engineering Center (TARDEC) in Warren, Mich., the current project may one day be part of the latest fuel saving features in a Chevrolet or Ford.

Many current features we take for granted in our high-tech cars were first developed for military or defense related purposes. For example, proximity sensors that help us park and detect unseen obstacles were first applied to anti-aircraft detection. The well-known military technology known as radar has been adapted to produce some of the features we now enjoy on autos.

According to an article by Jeff Green of the Bloomberg News, TARDEC’s current project involves converting the exhaust heat of tanks to electricity to power the onboard computer, something especially applicable to desert warfare.

Given the new CAFE standards, this is just the sort of new tech likely to show up on cars in the not too distant future. Just last June Torque News posted an article about the effort to find the right thermocouple configuration to efficiently convert the waste heat energy combustion cars produce to augment the electric power of the automobile.

Despite the governmental budget cutbacks, chances are it takes a gigantic corporation to out fund the government outlay in securing our homeland. That’s why the infrared scanners some cars now employ to detect wildlife or pedestrians at a sufficient distant to safely respond are the result of military research. Infrared scanning or vision can be useful in detecting an enemy in dark, obscured or simply vast expanses.

This correlation between automotive and military pure science has been around for a long time. A perfect example is the Jeep, first produced for the armed services in WWII and then adapted to extremely successful civilian purposes when the war was over.

“Just about any material used in a passenger car was probably improved with military research,” John Wolkonowicz, an independent auto analyst in Boston specializing in automotive history told Bloomberg News.

The automakers are big enough to put billions of dollars into the effort to improve fuel efficiency and develop alternative energy vehicles to the CAFE requirements. Meanwhile at TARDEC a $60 million lab is looking into batteries using unusual chemical reactions to extend vehicle range and working on fuel cells that convert hydrogen directly into electricity with no detectable emissions.

The lab is just 17 miles north of the Detroit headquarters of General Motors, meaning the U.S. Big Three have the inside line to the technology TARDEC develops. The site has long been a seething crucible of creation.

At the very beginning of WWII in August of 1940, the Army picked Chrysler Corp. to build the nation’s original state-owned, privately-operated fabrication plant known as the Detroit Arsenal Tank Plant, soon to be labeled the Arsenal of Democracy. The first prototype tank built by the facility, an M2, was completed in April 1941, states the official history of the plant. The Arsenal was soon switched to the production of the M3 tank, with M2 fabrication moved to the Rock Island Arsenal.

GM was also part of the war effort of the Greatest Generation and their experience and learning from the production of M-5 light tanks served to later improve Cadillac's automatic transmissions, according to Wolkonowicz. The tanks had powertrains linking two Cadillac engines with corresponding automatic transmissions. The demanding requirements of military vehicles in warfare provided the perfect learning lab, the resulting postwar quality of the combat-tested Cadillac transmission doubtless helped to build the brand’s mid-century mystique.
