Full-Scale Engine Research in AWT (1951).Performance of Various Types of Aircraft Engines (1947).Comparison of Turbojet, Afterburner, and Ramjet in AWT (1947).NACA Inspection Talks on the AWT (1947).AWT Investigations of Jet Engines (1945).The AWT contributed to a succession of advancements of jet engines that resulted in a tremendous surge in thrust capabilities in the late 1940s and early 1950s. The AWTРІР‚в„ўs most important contributions to the jet engines of this era involved restarting at high altitudes, afterburners and variable-area nozzles, and windmilling. Researcher then attempted to introduce various modifications to improve the performance. Most AWT test programs first determined the engineРІР‚в„ўs performance and operating range at different altitudes. Researchers operated the engines over a range of altitudes, velocities, and engine speeds. The AWTРІР‚в„ўs post-war research focused on the improving engine performance at high altitudes and refining components such as the afterburner. They also studied other types of engines, including the turboprop and ramjet.

NACA researchers conducted extensive testing of General ElectricРІР‚в„ўs (GE) TGРІР‚вЂњ180 and TGРІР‚вЂњ190 and WestinghouseРІР‚в„ўs 24C and J40 during this period. For most investigations, the airflow was ducted directly into the engine inlets.

The NACA upgraded the Altitude Wind Tunnel (AWT) several times during the 1940s and 1950s to keep up with the increasingly more powerful jet engines. With the end of World War II in the fall of 1945, the laboratory ( renamed the Lewis Flight Propulsion Laboratory in 1948) underwent a major reorganization to focus on the new turbojet and missile technologies. The AWTРІР‚в„ўs post-war testing and improvement of axial-flow turbojet engines was the facilityРІР‚в„ўs most enduring contribution to the aerospace field.
