Abstract 3. Recipient's Catalog No. 5. Report Date January 1976 6. Performing Organization Code 8. Performing Organization Report No. H-905 10. Work Unit No.. 512-53-03 11. Contract or Grant No. 13. Type of Rewrt and Period Covered Technical Note 14. Sponsoring Agency Code - In response to the interest in airplane configuration characteristics at high angles of attack, an unpowered remotely piloted 3/8-scale F-15 airplane model was flight tested. This report documents the subsonic stability and control characteristics of this airplane model over an angle of attack range of -2OO to 53O. The remotely piloted technique for obtaining flight test data was found to provide adequate stability and control derivatives. The remotely piloted technique provided an opportunity to test the aircraft mathematical model in an angle of attack regime not previously examined in flight test. The variation of most of the derivative estimates with angle of attack was found to be consistent, particularly when the data were supplemented by uncertainty levels.
