Smoke generators and yarn tufts are used for flow visualization studies on an F/A flown by NASA's Dryden Flight Research Center, Edwards, Calif., in its High Alpha Research Vehicle (HARV) by: 1.
The NASA F/A High Alpha Research Vehicle (HARV) has been the flight test bed of a focused technology effort to significantly increase maneuvering capability at high angles of attack. Development and flight test of control law design methodologies, handling qualities metrics, performance guidelines, and flight evaluation maneuvers are described.
NASA Formulation of the High- Alpha Technology Program With this recent interest in high-a flying qualities in the aircraft community, NASA has emphasized high-a research as well, although NASA has always been interested in high-a flight. Research conducted by NASA includes aileron rudder interconnects, thrust vectoring, and unconventional.
In high alpha, the air is moving vertically from the bottom of the nose to the top instead of horizontally from front to back. By changing the deflection of one of the strakes more than the other, the pilot can push the nose one way or the other.
In normal forward flight, they aren't much use. Full write up from NASA here. In flight test programs conducted with NASA Dryden Flight Research Center, Systems Technology explored high speed flying qualities with the SR and evaluated high angle-of-attack demonstration maneuvers with the F/A High Alpha Research Vehicle.
More recently, aircraft icing identification techniques were evaluated with the NASA Twin Otter. NASA F/AC High Alpha Research Vehicle. Repaint of NASA HARV F/AC Hornet using Acceleration default F Textures only.

His flight-test experience includes loss of control mitigation and handling qualities evaluations using the Calspan Learjet in-flight simulator, ground-handling evaluation of the T, a probe-and-drogue demonstration-maneuver evaluation program conducted by the USAF Test Pilot School using the variable-stability NTA, a poststall maneuvering.
A high-fidelity nonlinear model of the F/A is developed for controller analysis using F/A High-Alpha Research Vehicle aerodynamic data in the open literature.
He started as a research engineer in structural dynamics working on flight research programs such as FXL, X, and High Alpha Research Vehicle doing ground vibration testing and flight flutter testing. His research included flight flutter techniques, active structural damping, and piezoelectric systems tests.
InDavid was the chief. High Agility Flight Dynamics and Control of Aircraft Control Methods • Handling qualities and control laws are very important for an agile aircraft.
• No use of agility if the control system is sluggish and inaccurate. “An Overview of Controls and Flying Qualities Technology on the F/A High Alpha Research Vehicle”, NASA NASA used the F High-Alpha Research Vehicle (HARV) to flight-validate high angle-of-attack (alpha) handling qualities that had not been done previously because of the difficulty in performing such tests in a safe and methodical manner.
F/A stabilators were also used as canards on NASA's FS/MTD.

NASA used the F HARV to demonstrate flight handling characteristics at high angle-of-attack (alpha) of 65–70 degrees using thrust vectoring vanes.
 F/A stabilators were also. The high wing sweep and taper meant that wing tip stall would be a problem and an airfoil with smooth stalling characteristics was required for the wing tips. The high speed NACA 6A (straight trailing edge) series of airfoils offered the best design flexibility for such an application.
Hypersonic flight, traditionally defined as speeds above Mach 5, meant new problems for aerodynamicists, one of which was the role of heating. At high speeds, friction causes the surface of a vehicle to heat up.
At Machthe speed NASA's X research aircraft reached in the early s, temperatures exceed ° F (° C). NASA is Born The research in high-speed, high-altitude flight resulted in a solid foundation for manned orbital flight. Langley’s accomplishments in the s were remarkable.
