The High Alpha Research Vehicle is a modified American McDonnell Douglas F/A-18 Hornet used by NASA in a three-phase program investigating controlled flight at high alpha (angle of attack) using thrust vectoring, modifications to the flight controls, and with actuated forebody strakes. The program lasted from April 1987 to September 1996.

NASA’s F/A-18 High Alpha Research Vehicle, also known as the “Silk Purse,” performs a thrust vectoring test in afterburner in 1991, while anchored to the ground.

2015年6月29日 · NASA's Dryden Flight Research Center, Edwards, CA, used an F-18 Hornet fighter aircraft as its High Angle-of-Attack (Alpha) Research Vehicle (HARV) in a three-phased flight research project lasting from April 1987 until September 1996.

2023年11月15日 · The F/A-18 High Alpha Research Vehicle (HARV) retains the basic F/A-18 cockpit controls with some exceptions. Smoke generators and yarn tufts are used for flow visualization studies on an F/A-18 flown by NASA's Dryden Flight Research...

One of the objectives of this program is flight validation of ground-based design methodologies, and a modified F-18 aircraft was used to this end. This aircraft is called the NASA F-18 High Alpha Research Vehicle (HARV).

2019年2月27日 · During a three-phased flight research project lasting from 1987 until 1996, NASA’s Armstrong Flight Research Center used an F-18 Hornet fighter aircraft as its High Angle-of-Attack (Alpha) Research Vehicle (HARV) and completed 385 research flights.

scale developmental, twin-engine, single-place, F-18 fighter-attack aircraft. Built by the Mc-Donnell Douglas (St. Louis, Missouri) and Northrop (Newbury Park, California) Corporations for the U.S. Navy, this aircraft is powered by two modified F404-GE-400 afterburning turbofan engines (General Elec-tric, Lyn. , Massachusetts) .

The NASA F/A-18 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, per-

2023年8月6日 · The document provides an overview of NASA's F-18 High Alpha Research Vehicle (HARV) program, which included three phases to research flight at high angles of attack. The first phase gathered data using the standard F-18 configuration. The second phase added thrust vectoring vanes to the engines.

The F-18 HARV is powered by two modified General Electric (Lynn, Massachusetts) F404-GE-400 afterburning turbofan engines rated at approximately 16,000 lbf of static thrust at sea level.
