The objective of this study was to investigate the stability derivatives and the stability of the vectored thrust P-1127 airplane. Expressions were derived for the derivatives. The performance, derivatives and stability were found for both an accelerating and nonaccelerating transition from hover to conventional flight. The results of the accelerating transition were compared to values available from Hawker Siddeley. Both transitions were unstable for many airspeeds but the times to double amplitude were such that a pilot could control the airplane. (Author)
