SPIN AND RECOVERY TESTS OF A 1/28-SCALE MODEL OF THE YF-93A AIRPLANE

Abstract

Spin tests were made in the Wright Field 12-ft vertical wind tunnel. Conclusions are presented (on the basis of these tests) regarding the spin and recovery characteristics of the aircraft at 20,000 ft. These include: (1) for all load conditions and configurations tested, with ailerons held against the spin (stick left for a right spin), recovery attempts by full rudder reversal will fail to termiate the spin; (2) satisfactory to marginal recoveries will result from full rudder reversal and simulataneous movement of ailerons to full with the spin (stick right for a right spin); (3) the elevators should be full up during the first part of the spin recovery attempt for fastest recovery; and (4) the gross weight at take-off and the design gross weight over target conditions are more adverse to recovery
