A TMT (Transverse Mounted Thrust) nozzle is a component used in rocket propulsion systems designed to direct the exhaust flow to produce thrust. It is mounted transversely, meaning it is oriented perpendicular to the primary axis of the vehicle. This nozzle configuration is crucial for maneuvering and controlling the direction of thrust. The nozzle's design involves precise engineering to handle high temperatures and pressures, ensuring efficient thrust generation while maintaining structural integrity. TMT nozzles are commonly used in spacecraft and missiles, where precise control of the thrust vector is essential for accurate navigation and stability.
