F-18 Systems Research Aircraft (SRA) in flight
A NASA F/A-18, specially modified to test the newest and most advanced system technologies, on its first research flight on May 21, 1993, at NASA's Dryden Flight Research Facility, Edwards, California. Flown by Dryden in a multi-year, joint NASA/DOD/industry program, the F/A-18 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. 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.

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.

The National Aeronautics and Space Administration's Systems Research Aircraft (SRA), a highly modified F-18 jet fighter, during a research flight. The former Navy aircraft was flown by NASA's Dryden Flight Research Center at Edwards Air Force Base, California, to evaluate a number of experimental aerospace technologies in a multi-year, joint NASA/DOD/industry program. Among the more than 20 experiments flight-tested were several involving fiber optic sensor systems. Experiments developed by McDonnell-Douglas and Lockheed-Martin centered on installation and maintenace techniques for various types of fiber-optic hardware proposed for use in military and commercial aircraft, while a Parker-Hannifin experiment focused in alternative fiber-optic designs for position measurement sensors as well as operational experience in handling optical sensor systems. Other experiments flown on this testbed aircraft included electronically-controlled control surface actuators, flush air data collection systems, "smart" skin antennae and laser-based systems. Incorporation of one or more of these technologies in future aircraft and spacecraft could result in signifigant savings in weight, maintenance and overall cost.

One of NASA's F/A-18 Hornets on the ramp at the Dryden Flight Research Center, Edwards, California at dawn August 6, 1993. F-18 aircraft, on loan to NASA by the U.S. Navy, were flown at Dryden as support aircraft and as research testbeds. As support aircraft, they were used primarily for safety chase, pilot proficiency and aerial photography. As research aircraft, they were involved in thrust vectoring and high angle of attack research, as well as numerous smaller scale experiments.
Bob Cummings, a technician at NASA's Dryden Flight Research Center, Edwards, California, checks out a new "Smart Skin" antenna mounted on the tip of the right vertical fin of Dryden's F/A-18 Systems Research Aircraft. Flight tests of the antenna system demonstrated a five-fold increase in voice communications range and a substantial improvement in the pattern of radiation and quality of transmission compared to the standard dorsal blade antenna on the aircraft. The Smart Skin antenna system was electrically as well as physically connected to the airframe, making the aircraft skin operate as an antenna along with the antenna itself. The concept was developed by TRW Avionics Systems Division and integrated into the F/A-18's vertical fin by Northrop-Grumman Corporation.
