Problems solved by technology

[0002] The central cone of the traditional axisymmetric plug nozzle is connected to the cylinder of the nozzle through a fixed connection, and the realization of vector adjustment is generally divided into two types: one is to design the cylinder as two spherical segments at the front and the rear, and through The actuating system and the connecting mechanism drive the rear segment of the spherical segment to realize vector adjustment. The nozzle with this structure has a larger outline and is heavier. It is not easy to implement for an engine with strict requirements on the outline size; the other is through the actuation system. The overall deflection of the nozzle cylinder has a large force and a complicated mechanism, so it is necessary to design a simple mechanism to realize the omnidirectional vector adjustment of the axisymmetric plug nozzle

Abstract

The invention discloses a novel ball socket plug type vector nozzle. The novel ball socket plug type vector nozzle comprises a fixed nozzle shell, a movable nozzle shell and a plug cone, wherein the movable nozzle shell and the plug cone fixedly suspended inside the movable nozzle shell are in an integrated structure, and the outer peripheral surface of the plug cone is matched with the inner profile surface of the movable nozzle shell to form a convergence section and an expansion section; and the front section of the movable nozzle shell and the rear section of the fixed nozzle shell are connected in a spherical pair mode, and a movable body supporting lug arranged on the outer profile surface of the movable nozzle shell is connected with a servo system to drive the movable nozzle shell to drive the plug cone to swing.

Description

technical field [0001] The invention relates to the thrust vectoring technology of solid rocket motors, in particular to a novel ball-and-socket type vectoring nozzle. Background technique [0002] The central cone of the traditional axisymmetric plug nozzle is connected to the cylinder of the nozzle through a fixed connection, and the realization of vector adjustment is generally divided into two types: one is to design the cylinder as two spherical segments at the front and the rear, and through The actuating system and the connecting mechanism drive the rear segment of the spherical segment to realize vector adjustment. The nozzle with this structure has a larger outline and is heavier. It is not easy to implement for an engine with strict requirements on the outline size; the other is through the actuation system. The overall deflection of the nozzle barrel has a large force and a complicated mechanism, so it is necessary to design a simple mechanism to realize the omnid...
