Investigation of Control and Stability Augmentation Requirements for Tandem Tilting Ducted Propeller VTOL Transports

摘要

Theoretical and analog computer investigations were conducted to determine the control and stability augmentation requirements for tandem tilting ducted propeller VTOL transports. The type of aircraft considered had performance capabilities similar to those required for the Tri-Service VTOL Transport.nInitial studies were directed toward establishing representative aerodynamic characteristics for the aircraft. Calculated handling qualities were then compared with existing handling qualities criteria to evaluate the performance of constantgain, programmed-gain, and adaptive control and stability augmentation systems.
