Book excerpt: Gyroscopic cross coupling between pitch and yaw was simulated with a variable-stability helicopter while hovering in a yawing maneuver to ascertain the effect of cross coupling on handling qualities. Pilot ratings of the controllability of cross coupling were obtained for various combinations of longitudinal control power, angular velocity about the yaw axis, and simulated engine angular momentum. A theoretical investigation, supplemented by simulator data, was undertaken to determine the effect of longitudinal damping on the coupling controllability. Also, a comparison was made between flight and simulator data. The results indicated that for an aircraft with otherwise satisfactory longitudinal handling qualities, the level of cross coupling is satisfactory when less than 30 percent of the available longitudinal control will trim out the largest gyroscopic coupling moment which might be encountered. Increased longitudinal damping resulted in a significant increase in the controllability of pitch-yaw gyroscopic cross coupling.

This book was released on 1961 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental and theoretical investigation indicates the extent to which the amount of cross coupling present in an aircraft is dependent on the angular-velocity damping and moments of inertia of the aircraft as well as the angular momentum of the engine. The amount of cross coupling which the pilot can tolerate is a function of the maneuvers encountered and the aircraft control power. A criterion based on pilots' opinions obtained from the simulation flights provides a means for determining the acceptability of cross coupling in VTOL aircraft as a function of the aircraft design parameters.

This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A visual flight investigation indicates the extent to which cross coupling affects handling qualities as a function of engine angular momentum, angular velocity about the yaw axis, and longitudinal control power. A theoretical examination, supplemented by simulator data, indicates the extent to which increased longitudinal damping improves the coupling controllability.
