Performance Study of Thrust Control Unit with the Various Geometric Shapes
Kyoung-Ryun Kim,Jong-Ho Park 한국유체기계학회 2016 International journal of fluid machinery and syste Vol.9 No.4
This study aims to identify aerodynamic characteristics of the ramp tab, a mechanical deflector, by conducting a non-combustive experiment using compressed air and supersonic flow test equipment. With the ramp tabs installed symmetrically and asymmetrically on the outlet of the supersonic nozzle, the structure of the flow field, the thrust spoilage, the thrust deviation angle, and the lift/drag coefficients were derived and analyzed. The results show that the asymmetrically-installed ramp tabs are advantageous relative to the symmetrically-installed tabs in terms of the performance of thrust vector control, thrust deviation angle, and lift coefficient.

The characteristics and classifications of thrust vector control(TVC) systems for rocket motors are reviewed and the development trend and the applications of the TVC systems are studied. The TVC system is mainly effective while the rocket motor is operating, but that auxiliary motors can be used after the operation of the rocket motors. The TVC system is applied to the movable or fixed nozzle in accordance with the purpose of the rocket motors.
