THIOVEC (Trademark) TVC Nozzle Warm Gas Actuation.

摘要

Warm gas actuation of a THIOVEC TVC nozzle was demonstrated using a solid propellant gas generator and a solenoid operated bi-stable flapper-type warm gas valve. The TVC nozzle's dynamic characteristics were obtained in a series of bench tests with simulated motor chamber pressure producing the resistive torques normally experienced under motor operating conditions. These bench tests provided frequency response, phase lag, slew rate, and system hysteresis data which proved the system to be a viable candidate for low-maintenance, cost-effective TVC nozzle system applications.
