NOMENCLATURE PR = pressure ratio D exit = nozzle exit diameter A/D = analog to digital I/O = input and output • m = mass flow rate P(s) = SR-30 turbojet engine transfer function G c (s) = PID controller transfer function K p = proportional gain T i = integral time constant T d = derivative time constant
Studied the feasibility of adaptive optics for laser Doppler wind velocity measurements and laser power beaming from Earth to a lunar base. Developed models suitable for system identification algorithms to determine wind profiles from laser distortion measurements. Developed computer software tools for computer graphics, time series analysis and simulation.
