 The throttle is intended to
distribute and regulate flowrate of high-temperature gas from LRE gas generator between pairs of steering nozzles in pitch/yaw/roll.
The throttle-distributor (TD) contains housing with one or two outlet windows that are semi-closed in an initial position by
a cylindrical gate. The latter is turned by electromechanical or hydraulic actuator under commands of the control system.
High reliability and service life are ensured by:
- design simplicity;
- application of heat-proof and heat-resistance friction-less sealing materials.
The required throttle characteristics is provided by respective shaping of outlet windows.
