Westinghouse J32

From Wikipedia, the free encyclopedia

The Westinghouse J32 was a small turbojet engine developed by the Westinghouse Aviation Gas Turbine Division in the mid-1940s.

Design and development

Development of the 9.5A (military designation J32-WE-2) began in late 1942, and Westinghouse delivered the first engine to the U.S. Navy in mid-1944. The Navy selected the 9.5A to power the Gorgon II-B and III-B air-to-air missiles, but these applications did not materialize."

An improved version, the 9.5B, powered the Martin TD2N-1 Gorgon high-speed target drone, which successfully flew in 1945. The engine's high cost and continuing development delays led to the cancellation of the TD2N-1 program in 1946. Westinghouse manufactured 24 of the 9.5A and 20 of the 9.5B engines. Despite their limited use, they constituted the first family of small turbojet engines successfully developed and produced in the United States.
