[Victoria A Regenie; Dryden Flight Research Facility.;]. The F HARV (High Alpha Research Vehicle), is an F variant modified to invest controlled flight at high angles of Attack. To do that it is equipped with a Thrust Vector system (TVC), advanced flight controls, and actuated forebody strakes.

The program was started in April and lasted until September The F HARV (High Alpha Research Vehicle), a former NASA research aircraft, was used to improve the safety and maneuverability of modern military fighters in combat situations.

Flight research with the HARV increased our understanding of flight at high angles of attack, helping makers of U.S fighter jets design features that will make fighter jets.

F/A High Alpha Research Vehicle Image Gallery | NASA. The Hornet's normally high angle of attack performance envelope was put to rigorous testing and enhanced in the NASA F High Alpha Research Vehicle (HARV).

NASA used the F HARV to demonstrate flight handling characteristics at high angle-of-attack (alpha) of 65–70 degrees using thrust vectoring vanes. [22]Manufacturer: McDonnell Douglas (–).

During the final phase of tests with the F/A High Alpha Research Vehicle (HARV), Dryden technicians installed nose strakes, which were panels that fitted flush against the sides of Cited by: 1. Published on The High Alpha Research Vehicle (high angle of attack) was a modified F/A Hornet used by NASA in a 3-phase program investigating controlled flight at high.

The F high alpha research vehicle was recently modified by adding a thrust vectoring control system. A key element in the modification was the development of a research flight control system integrated with the basic F flight control system.

This video presents raw, unedited material of Dryden's F High Alpha Research Vehicle (HARV) aircraft. The F HARV proved to be a useful research tool with many unique capabilities.

The thrust vectoring system, reprogrammable mission computer and On-Board-Excitation-System, and a unique ability to rapidly reprogram flight controls allowed. Flight test maneuvers are specified for the F High Alpha Research Vehicle (HARV).

The maneuvers were designed for closed loop parameter identification purposes, specifically for longitudinal and lateral linear model parameter estimation at 5, 20, 30, 45, and 60.
