U.S. technicians complete work on turbo jet engine. Technicians in a General Electric Company plant in the eastern U.S. state of New York complete work on a turbo jet airplane engine which will be used to provide power in a propellerless P-59A fighter plane. This is one of the first photographs of a turbo jet engine released by the U.S. Army Air Forces. Maintenance of jet engines, which are simple in operation, requires less than one-fifth the time and labor required for maintanance of a conventional airplane engine. In the jet engine, air enters the front, goes through compressors, mixes with kerosene in combustion chambers where the mixture ignites, and the blasts out through a pipe in the reat to provide the force that moves the plane. The jet engine has only one-tenth the number of moving parts of an ordinary reciprocating engine. The engine requires no warmung up and the pilot can take off one minute after pressing the starter button in the jet-proprelled plane. Propeller-less planes, which attain great speed will be used against the Japenese "if they are needed", Army Air Forces authorities have stated.
