NASA’s F-15B (upper right), later used for aerodynamic flight research, is seen here with the F/A-18B Systems Research Aircraft, on a flight from the Dryden Flight Research Facility, Edwards, Calif.
Currently being flown by Dryden in a multi-year, joint NASA/DOD/industry project, the F/A-18B has been modified into the 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 being tested aboard the SRA F/A-18 is an advanced air data sensing system which uses 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 is being evaluated for possible use on the X-33 and X-34 reusable space-launch vehicles. The primary goal of the SRA project is 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.
NASA’s F-15B aircraft is being used by Dryden as an aerospace research aircraft. Certain experiments can be placed on the Flight Test Fixture, which is mounted under the fuselage. The research projects can then be subjected to different aerodynamic loads, speeds, and temperatures. The F-15B, No. 836, was acquired in 1993 and is also used at Dryden as a research support aircraft.1993NASA Photo / unknown› 1990s Fleet Description
