AEDC support aids F-15 in reaching 50-year milestone

A scale model of the F-15 Eagle undergoes testing in the early 1980s in the 4-foot transonic wind tunnel at Arnold Air Force Base, Tennessee, headquarters of Arnold Engineering Development Complex. The Air Force recently celebrated the 50th anniversary of the F-15’s deployment. Models of the aircraft, engines and other F-15 components have frequently been tested by AEDC over the past 50 years.

AEDC support aids F-15 in reaching 50-year milestone

The compatibility of the Pratt & Whitney F100 engine to the variable geometry inlet of the F-15 Eagle is evaluated in 1972 in the 16-foot supersonic wind tunnel at Arnold Air Force Base, Tennessee, headquarters of Arnold Engineering Development Complex. Since the test section was not large enough to accommodate a full-sized nose section, a special fuselage segment designed to produce inlet airflow conditions the F-15 would encounter in flight was installed in the wind tunnel. The test hardware was cycled through a wide range of altitude and speed conditions. The Air Force recently celebrated the 50th anniversary of the F-15’s deployment.

AEDC support aids F-15 in reaching 50-year milestone

A modified F-15 Eagle is flown in the late 1970s by NASA personnel at what was then known as the Dryden Flight Research Center in California to obtain aerodynamic measurements on an instrumented cone to compare with similar data taken with the same cone in nearly two dozen foreign and domestic wind tunnels. The program originated at Arnold Engineering Development Complex, headquartered at Arnold Air Force Base, Tennessee, with the purpose of developing a mathematical means of eliminating noise effects from wind tunnel data to improve its correlation with flight data.

AEDC support aids F-15 in reaching 50-year milestone

Hundreds of instrumentation lines used to sense or measure various aspects, including temperature, pressure, fuel flow and vibration, are connected to an early version of the Pratt & Whitney F100 engine in the late 1960s to prepare it for a 1970 test in one of the high-altitude test cells at Arnold Air Force Base, Tennessee, headquarters of Arnold Engineering Development Complex. The F100 would become the power plant for the F-15 Eagle. The Air Force recently celebrated the 50th anniversary of the F-15’s deployment.

Some of the dozens of different store models used during wind tunnel testing of the F-15E Strike Eagle dual-role fighter aircraft by Arnold Engineering Development Complex, headquartered at Arnold Air Force Base, Tennessee, are shown in this photo from the early 1990s. More than 500 aircraft and store configurations have been investigated throughout the years to ensure that the F-15E can safely deliver the wide array of weapons needed to accomplish its air-to ground and air-to-air missions. The Air Force recently celebrated the 50th anniversary of the F-15’s deployment. Models of the aircraft, engines and other F-15 components, including those of the F-15E, have frequently been tested in AEDC facilities over the past 50 years. (U.S. Air Force photo)
