Flight tests were conducted by NASA with the basic YAV-8B to establish reaction control bleed flow in low-speed flight to measure jet-induced ground effects, and to conduct infrared measurements of hot gas flow fields near the ground for correlation with computational fluid dynamics predictions.

Flight tests were conducted by NASA with the basic YAV-8B to establish reaction control bleed flow in low-speed flight to measure jet-induced ground effects, and to conduct infrared measurements of hot gas flow fields near the ground for correlation with computational fluid dynamics predictions. The bleed-flow tests provided a detailed look at the attitude-control power used by the pilot during maneuvers in all the phases of jet-borne flight. Flight research was completed with this aircraft in late 1997.
