Lead screw push rod type aircraft head deflection driving device

Abstract

The invention discloses a lead screw push rod type aircraft head deflection driving device. The aircraft head deflection driving device can generate a greater deflection angle and can provide a greater overload, and the rotation in the aircraft head deflection angle being 0 to 15 degrees and the head deflection azimuth angle being 0 to 360 degrees can be realized; in addition, when the aircraft head requires any deflection, aircraft head installing equipment can be enabled not to interfere with an aircraft head case. When the aircraft head needs to deflect, an aircraft computer sends out signals, a power mechanism receives control signals, the power mechanism drives a lead screw pushing tube to rotate, a lead screw steering mechanism converts the rotating movement into the vertical movement of a push rod mechanism, a push rod aircraft head and a rotating connecting arm mechanism rotate around a spherical sleeve, the deflection angle of the aircraft head realizes the accurate following according to input signals, the influence of the hinge moment is overcome, and the aircraft head is driven to fast deflect.

Description

technical field [0001] The invention relates to a deflection drive device, in particular to a lead screw push rod type aircraft head deflection drive device. Background technique [0002] The aircraft head deflection control device means that the aircraft head deflects at a certain angle relative to the aircraft fuselage in any direction, and generates a corresponding aerodynamic force on the aircraft head, that is, the control force of the aircraft, thereby generating a control moment relative to the center of mass of the aircraft. Make the aircraft produce a corresponding attitude angle, and finally produce maneuvering overload. The aircraft head deflection control device can realize the movement of the aircraft on the yaw and pitch channels. [0003] In the existing published technical documents, the aircraft head deflection driving mechanism has the following forms, namely piezoelectric ceramic type, magnetostrictive type, hydraulic type and swash plate type.

AI Technical Summary

Problems solved by technology

[0005] Piezoelectric ceramic and magnetostrictive materials are very expensive, and the deformation produced is relatively small, which requires a relatively complicated amplification mechanism and requires very strict conditions of use.

Although the hydraulic deflection drive mechanism can provide a large torque, it needs to be equipped with a gas and liquid structure, and is greatly affected by the ambient temperature; the swash plate type is likely to cause coupling when the aircraft head is deflected, and it can carry Less lateral overload
