    In 1966, Ford fitted a production W-1000 6x4 tractor with a low pressure 375 horsepower model A-707 gas turbine and demonstrated it in North America and Europe (the UK and Germany).

     

    Ford said they had “succeeded in overcoming the problems previously experienced in harnessing the gas turbine engine. The Ford A-707 engine is now in use in surface vehicles, land and water, in addition to industrial generator applications. It features a unique regenerative system which recaptures exhaust waste, a variable turbine nozzle and electronic controls”.

     

    In 1970, following 18 years of gas turbine research, Ford opened a gas turbine engine plant in Toledo, Ohio to build and sell turbine engines for heavy truck, bus, marine and industrial usage. But Ford closed the plant in 1973, after continuing issues of turbine heating, and a devastating flood that shuttered a single-source supplier’s only plant. (Ford got out of the turbine business just as Mack and GM were beginning to use new ceramic materials to create second generation gas turbines)

     

    Here’s an impressive Ford promotional video on the gas-turbine powered W-1000 COE.

    Turbine Trucks in the Future

     

    Commercial Motor  /  November 4, 1966

     

    FORD OF AMERICA, convinced that the turbine engine will play an important part in trucks of the future, has announced a new 375 h.p. prototype research gas turbine engine designed specifically for a current truck model.

     

    Called the Model 707 Turbine, the new engine made its debut at this month's annual meeting of the American Trucking Association in Washington, and has been installed in a U.S.-spec Ford W-1000 heavy truck.

     

    Marketing of the 707 is not expected before the early 1970s and to advance the turbine design towards production stage, Ford has put a new gas turbine laboratory into operation at its Dearborn (Michigan) research and engineering centre.

     

    Nearly 15 years' work by Ford engineers went into the new engine, which, claims Ford, provides numerous technical and operational advantages. "For instance," says the company," compared with a conventional truck engine of equivalent h.p., the new 707 weighs one ton less and occupies considerably less space. It can pull nearly 37 tons at up to 70 m.p.h."

    European Debut of Ford Gas Turbine

     

    Commercial Motor  /  August 16, 1968

     

    Ford Motor Co.'s announcement that the latest version of the US Ford 707 automotive gas turbine will be exhibited next month at the Commercial Motor Show, Earls Court, gives point to the forecasts made by Mr. Walter Manning, chief engineer of Ford Truck Product Engineering, in this country, that the turbine will take over from the diesel for heavy vehicle applications. And it highlights the fact that the brain power behind the design and development of the 707 has been supplied by Mr. Ivan Swatman, a British-born engineer.

     

    Mr. Swatman will unveil the 707 at Earls Court in the same week that he describes the development of this and other Ford turbines in a most revealing and important paper at CIVI's Fleet Management Conference at the London Hilton.

     

    The 375bhp Model 707 gas turbine made its domestic debut at the annual meeting of the American Trucking Association in Washington.

     

    In the second of “The Next 10 Years" series, Mr. Manning said that by the mid-1970s the gas turbine would be in a favorable position, compared with the diesel, for applications to heavy vehicles requiring power outputs of 250/300bhp. And he forecast that units with outputs as low as 200bhp would eventually be acceptable on economic grounds for trucking and some non-trucking vehicles.

     

    Designed to propel 35-ton tractor-trailer at speeds up to 70mph, the 707 is currently undergoing extended durability tests fitted in a W-1000 truck built by Ford of America. It saves about 2,000lb in weight compared with a diesel of comparable output and is said to operate at a fuel consumption equivalent to that of a diesel over a wide speed range. Moreover, it has a very low noise level.

     

    The unit should cover 600,000 miles between major overhauls, and is easy to service with conventional tools. The only wearing parts of the major components comprise the turbine shaft and bearings.

     

    Of particular importance for fuel economy, the 707 incorporates a regenerator in the form of two power-driven heat exchangers located between the turbine-driven compressor and the combustion chambers. The regenerator takes exhaust heat to preheat the incoming air, which reduces the amount of heat wasted in the combustion process. Combustion is continuous at temperatures of around 1,500/1,800 degrees F.

     

    Fuel economy is also improved by the use of variable-pitch vanes, which direct the hot gases from the combustion chamber to the power turbine. Changes of pitch are made to accord with changes of power output.

     

    The provision for varying the pitch of the vanes also enables the unit to be employed for overrun braking. A retarding force of up to 2801-ip is available from overrun braking at the touch of a pedal.

     

    Because the lubricated components are isolated from the combustion chamber, oil consumption is negligible. There is no radiator and the compactness of the engine facilitates siting of the auxiliaries. It also gives greater latitude in cab design.

     

    The compressor of the 707 operates at up to 37,500rpm, while the maximum speed of the power turbine is 31,650rpm. Reduction gearing gives an output-shaft speed of 3.000rpm.

     

    Liberal use is made of castings to facilitate the economic use of high-grade materials in quantity production of the unit. The main block, bearing housing and end covers are nodular-iron castings. Commercially available cast-nickel alloys are employed for the turbine wheels.

     

    Ivan Swatman. who is chief engineer of US Ford's turbine operations, is now an American citizen but was born in St. Albans, Hertfordshire, where he served an apprenticeship before taking a job as a development engineer with D. Napier and Son. He worked on experimental turbines with that company until moving to the USA as a project engineer on industrial turbines. Later he spent 6 years as project engineer on Solar Aircraft's industrial turbines before joining Ford at Dearborn in 1956. Since then he has been responsible for the design of all Ford's gas turbines.

    A Ford gas-turbine, presumably the model A-707, was also installed in a C-800 cab-forward vocational chassis in 1966.
