- Summary
-
Summary: Results of spin-tunnel tests of 65 models indicated that when the airplane design simulated that of the earlier single-engine type, with mass distributed chiefly along the fuselage, aileron-with and elevator-up settings aided recovery, and the rudder was the predominant control for recovery. When the design approached the design of multiengine airplanes (or the more recent single-engine airplanes with wing tanks and wing armament) with the mass distributed chiefly along the wings, however, aileron-against and elevator-down settings were conducive to the most rapid recovery and the elevator was the predominant control. The primary importance of the mass distribution of an airplane in determining its spinning characteristics is demonstrated and a useful criterion for predicting the optimum control manipulation for recovery, based on a non-dimensional mass-distribution parameter, is presented. Charts that should be useful for such predictions to both the pilot and the designer are included.

"NACA WARTIME REPORTS are reprints of papers originally issued to provide rapid distribution of advance research results to an authorized group requiring them for the war effort. They were previously held under a security status but are now unclassified. Some of these reports were not technically edited. All have been reproduced without change in order to expedite general distribution."
