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
