AI Technical Summary

Technical Problem

The existing tail nozzle cannot adjust the thrust direction, causing the aircraft to lose attitude control at low speeds.

Method used

A vector nozzle was designed. By setting a drive mechanism at the head of the turbojet engine and a vector nozzle at the tail, the ±23° pitch swing of the vector nozzle is achieved by using components such as connecting rods, rocker arms, servos and universal joints to precisely control the thrust direction.

Benefits of technology

It achieves precise adjustment of thrust direction, improves the aircraft's attitude control capability at low speeds, and enhances overall strength and temperature resistance through high-temperature resistant materials and structural design.

Abstract

This invention discloses a vectoring nozzle for use in a turbojet engine. The nozzle includes a drive mechanism mounted at the head of the turbojet engine and a vectoring nozzle mounted at the tail of the engine. A rocker arm is coaxially rotatably connected to the output shaft of the drive mechanism. A connecting rod is provided between the drive mechanism and the vectoring nozzle. One end of the connecting rod is hinged to the outer wall of the vectoring nozzle, and the other end is connected to a bearing on the rocker arm. This invention provides a vectoring nozzle that, through the connecting rod, drives the vectoring nozzle to produce a pitch swing of ±23° relative to the turbojet engine, adjusting the thrust direction generated by the vectoring nozzle. Two servo motors are used to precisely control the pitch angle, yaw angle, and thrust direction of the vectoring nozzle. Compared to traditional sheet metal vectoring nozzles, this design offers higher precision, higher strength, and higher temperature resistance.
