Schematic Design and Computational Studies of Thrust Vector Control for Spacecraft

Electromechanical actuators have taken the place of hydraulic and pneumatic actuators in many applications, especially for the purpose of Thrust Vector Control (TVC). The aim of this project is to design and analysis of an electromechanical actuator for spacecraft applications using the analytical formulae and/or Finite Element Analysis techniques. The  major components of EMA are: Brushless  DC servo  motor,  belt drive and  a  roller  screw,  which  converts  rotational  input into  linear  output and column  to which the nozzle will be attached and a power supply. The design of 3-D model of the EMA has been drawn using AUTOCAD, which is then followed by the structural analysis using state of the art software ABAQUS for tensile and compressive stress analysis.
