The Princeton Pennsylvania Army Avionics Research Program. Take Off of Heavily Loaded Helicopters.

Abstract

ALSO AD-747 732.(*helicopters, takeoff), hovering, ground effect, mathematical models, flight paths, optimization, airspeed, accelerationcomputerized simulation, control theoryIn the report are given the results of the optimal control theory applied to the take-off of heavily loaded helicopters and the instrumentation requirements to enhance VTOL-STOL pilot flight control during the take-off maneuvers. The analysis and computation determined constrained and uncontrained extremal trajectories which maximize final altitude at a given distance (Research and Development Technical Report, ECOM 02412-4, August, 1969). The constrained optimal leads to a slightly decreased performance, but this is more than offset by the ease of implementation. The proposed take-off technique was simulated on an analog computer. A parameter sensitivity study was made which resulted in the formulation of specific instrumentation requirements. (Author)
