Rudder mounting structure of blowing model

Abstract

The invention relates to the technical field of blowing models, and discloses a rudder mounting structure of a blowing model. A model body, a rudder piece, an angle change piece and an adjusting pieceare included, the model body and the rudder piece are mounted and cooperated basically via a shaft hole and a rudder shaft respectively, a containing groove is formed in the model body, so that the angle change piece can be positioned in cooperation with a matching groove in a positioning shaft of the rudder piece through the containing groove, and further the rudder piece is fixed and the angleis controlled. The adjusting piece is arranged behind the angle change piece, and can control the angle change piece by means of threads on the model body, concretely, fixedly positions the rudder piece by compressing the angle change piece and remove the angle change piece to dismount or replace the angle change piece. The mounting structure is novel in structure, reliable in installation, can greatly improve the rudder piece changing efficiency, satisfies requirement of change the state of the blowing model, and is high in structural precision, wide in changeable angle, simple in operation and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of blowing models, in particular to a blowing model rudder plate installation structure. Background technique [0002] In the development process of various types of aircraft, especially various types of missile weapons, it is necessary to manufacture a blower model for aerodynamic testing and verification. The rudder is the most important control part of the aircraft, and it needs to change various angles in the blowing test. In the structural design of the traditional blowing model, the installation base and the rudder piece are always designed as one, and the change of the rudder piece angle is realized by processing a variety of rudder pieces with different angles. However, this method requires sufficient installation area and installation wall thickness on the model, which is difficult to realize for those blowing models with smaller models and thinner walls. And this structure has disadvantages such ...

Problems solved by technology

However, this method requires sufficient installation area and wall thickness for the installation part on the model, which is difficult to realize for those blowing models with small models and thin wall thickness.

Moreover, this structure has the disadvantages of time-consuming and labor-intensive processing, and the state is not easy to replace when the blowing test is carried out.
