An electromechanical power source is described for aerospace vehicles which comprises: (a) a solid propellant gas generator; (b) a turbine coupled to be driven by gas from the solid propellant gas generator; (c) an alternator coupled to be driven by the turbine; (d) means for measuring an output parameter of the alternator; (e) gas flow control valve for controlling the gas flow between the gas generator and the turbine, the gas flow control valve being an electromagnetically controlled flapper valve having a first gas output coupled to the input of the turbine, a second gas output coupled to an exhaust means and a gas input; and (f) control means for comparing the output parameter of the alternator with the required value of the parameter, the control means being coupled to control the gas flow control valve to adjust the gas flow to drive the output parameter to the required value. The control means is coupled to control the flapper valve to couple the gas flow to the turbine when the value of the parameter is lower than the required value of the parameter and to control the flapper valve to couple the gas flow to the exhaust means when the value of the parameter is higher than the required value of the parameter.
