For decades, NASA has utilized subscale models of aircraft to conduct full-size performance tests.
Since the 1920s, NASA has continuously improved testing techniques, facilities, and model sophistication.
These techniques have contributed to various aircraft types, including general aviation, civil transports, reentry capsules, and supersonic transports.
This manual delves into the considerations for applying subscale results to full-scale aircraft and examines results from significant aircraft programs at NASA's Langley Research Center, Dryden Flight Research Center, and Ames Research Center.
