Structure suitable for connecting air rudder with steering engine system

Abstract

The invention provides a structure suitable for connecting an air rudder with a steering engine system. The structure comprises a rudder shaft, a shaft sleeve and a connecting element, wherein the rudder shaft is installed on the air rudder; the shaft sleeve is installed on the steering engine; the rudder shaft is installed on the shaft sleeve through the connecting element; a second containing space is also arranged in the shaft sleeve; one side of the second containing space communicates with the outside, and the other side of the second containing space communicates with a first containingspace; and the connecting element is matched and installed in the second containing space and extends into the first containing space to be connected with an installation handle. By use of the structure that the rubber shaft is installed on the shaft sleeve through the connecting element, the quality of a guided missile is reduced, the structure is compact, the flight resistance of the guided missile is reduced, the structure can be simply assembled, the connection strength of the air rudder and the steering engine is increased, and therefore, the structure can bear a larger bending moment andtorque, has a better shearing force capability and can meet the power bearing requirement of the air rudder.

Description

technical field [0001] The invention relates to the field of missile overall design, in particular to a structure suitable for connecting an air rudder and a steering gear system. Background technique [0002] As the flight speed of missiles becomes faster and the requirements for maneuverability become higher and higher, the aerodynamic forces to be borne by missiles become larger and larger. Air rudders, as the main aerodynamic control torque output, need to withstand very large aerodynamic loads. [0003] At present, the connection between the air rudder and the steering gear system generally adopts a locally thickened connecting flange, which is connected to the steering gear system through screws. The air rudder strength test experiments show that this place is the weak link of the air rudder strength, and in order to reduce the force of the bolts, it is often necessary to increase the distance between adjacent screws, resulting in an increase in the size of the connect...
