The Westinghouse J30, initially known as the Westinghouse 19XB, was a turbojet engine developed by Westinghouse Electric Corporation. It was the first American-designed turbojet to run, and only the second axial-flow turbojet to run outside Germany (after the British Metropolitan-Vickers F.2).[1]

J30
Type	Turbojet
National origin	United States
Manufacturer	Westinghouse Aviation Gas Turbine Division
First run	19 March 1943
Major applications	FH Phantom
Developed into	Westinghouse J32 Westinghouse J34

A simple and robust unit with six-stage compressor, annular combustor, and single-stage turbine, it initially gave 1,200 pounds of thrust but improved to 1,600 in production versions. Its first flight was under a FG Corsair in January 1944. It was developed into the smaller J32, and the successful Westinghouse J34, an enlarged version which produced 3,000 pounds of thrust.

Das Westinghouse J30 war ein US-amerikanisches Turbojet-Triebwerk, das ab 1941 im Auftrag des Bureau of Aeronautics der US Navy entwickelt wurde. Zwischen der US Navy und den US Army Air Forces gibt es seit 1946 eine Übereinkunft, dass von der Marine beauftragte Strahltriebwerke gerade Nummern erhalten, während der Luftwaffe ungerade Nummern zugeteilt werden.[1]
