Component Development

The paper discusses design solutions for increased-power and high-power electric rocket propulsion systems to be used in orbit-to-orbit transfer vehicles and advanced spacecraft. It reviews characteristics of their components from the standpoint of the mission to reboost the spacecraft to their target orbits, to perform the operations of transportation to the lunar orbit and to explore deep space. It discusses key criteria and procedures for selection of components, as well as problem areas in their development and ground developmental testing. The paper analyses pros and cons of using various versions of propulsion systems based on medium- and high-power electrical propulsion engines, the current status of their component development, as well as the technical feasibility of conducting developmental tests on the ground. Key words: electric propulsion engine, propulsion system, propulsion module, propellant storage system, power supply and control system, vacuum chamber, vacuum system.

Simulation Results

With the development of AC (alternating current )technique, larger power PMSM ( permanent m- agnet synchronous motor ) has been applied in the marine electric propulsion systems. In this paper the imple- mentation of the DTC (direct torque control) systems for a variable-speed 4088kW PMSM in ship electric propulsion systems has been studied. A novel control method using SVPWM (space vector pulse width mo- dulation) was proposed and a SVPWM module was designed. Then a DTC – SVPWM simulation model of PMSM with the load of propeller was found. The simulation results shows that the variable frequency speed regulation system have good response performance in the process of the motor start or speedup and through comparing the simulation results with the experiment data of the PMSM, the validity of the model is verified.
