STUDY OF MOTION OF MODEL OF PERSONAL-OWNER ORnLIAISON AIRPLANE THROUGH THE STALL ANDnINTO THE INCIPIENT SPIN BY MEANS OFnA FREE-FLIGHT TESTING TECHNIQUE

摘要

A study of the motion of a personal-owner or liaison airplane through the stall and into the incipient spin has been made by cata¬pulting a dynamic model into still air. The results showed that the model became unstalled in inverted flight after its initial rotation of substantially l80° in roll. Since the rates of rotation were low, it may be inferred that termination of the incipient spin would be most readily obtained by proper control movements at this point.
