The SR-71 Blackbird

NASA YF-12 Blackbird Program

The joint NASA-Air Force YF-12 research program lasted 10 years (1969-1979) and produced a wealth of data on materials, structures, loads, heating, aerodynamics, and performance for high-speed aircraft.

Thermal Loads Research

To measure the thermal loads on the YF-12 required some extraordinary ground tests. At the supersonic speeds the aircraft achieved, high temperatures produced by friction with the atmosphere made it difficult to separate the aerodynamic from the purely thermal effects upon the airplane.
