The Effect of Helicopter Dynamics and Control Characteristics on Formation Flight is a theoretical study of the trajectory laws which are used to define a follower's nominal point and the control laws which determine the follower's required action. Effect of maneuvers is included in this effort to provide fundamental information on which to base the development of IFR Formation Flight equipment for the Army. Landing Control Theory for Decelerating VTOL Aircraft is an attempt to obtain optimal trajectories for decelerating landing and accelerating take-off maneuvers. The effect of acceleration, aerodynamic constraints, and terminal constraints are included in the problem formulation. Simplified equations of motion are developed and possible schemes for their solution are investigated in this start toward providing information on which development of guidance equipment can be based. A System Study of Low Visibility Approach and Landing is an effort to combine the control characteristics of Helicopters with the performance characteristics of the Pilot to determine guidance parameters needed for low visibility approaches. The models for the control characteristics, disturbances, and pilot have been chosen, and work has started on setting up a combined model. An Examination of Instrumentation Requirements to Permit Control of Helicopter and Future VTOL Flight Performance explores possible methods for improving the high gross weight take-off performance of helicopters by giving accurate aerodynamic information to the pilot in some appropriate way.
