Description: NASA's F/A-18 Hornet is seen here in a banked turn over Rogers Dry Lake in the Mojave desert on an early research flight. It was flown by NASA's Dryden Flight Research Center, Edwards, California, in a multi-year, joint NASA/DOD/industry program, the former Navy fighter was modified into a unique Systems Research Aircraft (SRA) to investigate a host of new technologies in the areas of flight controls, airdata sensing and advanced computing.

One of the more than 20 experiments tested aboard the SRA F-18 was an advanced air data sensing system which used a group of pressure taps flush-mounted on the forward fuselage to measure both altitude and wind speed and direction--critical data for flight control and research investigations. The Real-Time Flush Air Data Sensing system concept was evaluated for possible use on the X-33 and X-34 resuable space-launch vehicles.

The primary goal of the SRA program was to validate through flight research cutting-edge technologies which could benefit future aircraft and spacecraft by improving efficiency and performance, reducing weight and complexity, with a resultant reduction on development and operational costs.
