Thrust Vectoring F18 Hornet |The NASA Dryden HARV Project

Thrust Vectoring - on an F18 Hornet! The Story of the NASA Dryden HARV Project:
The F-18 HARV or High Alpha Research Vehicle was a NASA testbed used to study performance at high angles of attack or alpha. The aircraft flew from 1989 to 1996 in a 3 phased research program that progressively added modifications to the Hornet. Let's take a look at the specifications of the F-18 HARV
Specifications
Length: 56 FT (17.1 M)
Height: 10 FT 6 IN (3.2 M) AT CANOPY
Wingspan: 37 FT 5 IN (11.4M)
Maximum speed: initially Mach 1.8 (1,190 MPH/1,915 KMH), subsonic with later modifications
Phase 1 weight: 31,980 LB, WITH 6,480 LB OF INTERNAL FUEL 14,506 KG / 2939 KG
Phase 2 and 3 weight: 36,099 LB ALSO WITH 6,480 LB OF INTERNAL FUEL 16,374 KG / 2939KG
Engines: Thrust Class
Each General Electric
EACH F404-GE-400 turbofan engines,
each producing 16,000 LB of thrust 71.17 kN WITH afterburner.

The aircraft that would become the F-18 HARV was actually a pre production F/A-18 and the sixth one ever built. Having been assigned Bureau Number 160780, this particular F18 was chosen as a testbed because it had a spin chute installed as the NAVY had used it to evaluate spin performance and recovery. Under NASAs use the aircraft was designated number 840.
The HARV program was a joint effort between NASA's Dryden, Ames, Langley and Lewis research centers. By the time NASA received the aircraft, it had been cannibalized for spare parts so extensively by the Navy it was assumed that the aircraft would never fly again. In fact, the engineers cataloged 400 missing parts and virtually no documentation of the existing wiring system. To get 840 airworthy, the mechanics and technicians had to cut out the existing wiring, find substitute parts, assemble and rewire the aircraft. By the time they were done, the words "Silk Purse" were painted on the fuselage, a take on the expression you can't make a silk purse out of a sow's ear.
