Westinghouse 19B Turbojet in the Altitude Wind Tunnel

The Westinghouse 19XB turbojet seen from the side in the Altitude Wind Tunnel (AWT) test section at the National Advisory Committee for Aeronautics (NACA) Aircraft Engine Research Laboratory. Westinghouse started the development of a series of relatively small axial-flow turbojets for the Navy shortly after Pearl Harbor. In 1943 the 19A engine became both the first operational US-designed jet engine and the only U.S. turbojet incorporated into an aircraft during the war in Europe. In March 1943 Westinghouse agreed to create an improved six-stage 1400-pound thrust version, the 19B. The engine underwent its first test run a year later in March 1944. Almost immediately the navy agreed to Westinghouse’s proposal for the even larger 10-stage, 1600-pound-thrust 19XB prototype. By July 1944 the navy had contracted with the NACA for the testing of both engines in the AWT. The tunnel was the nation’s only facility for studying full-scale engines in simulated altitude conditions. The wind tunnel investigations, which began on September 9, 1944, revealed the superiority of the previously untested 19XB over the 19B. The 19B engines failed to restart consistently and suffered combustion blowout
