Pop-up mechanism applied to steering engine and steering wing of aircraft

Abstract

The invention discloses a pop-up mechanism applied to an aircraft steering engine and a rudder wing, the pop-up mechanism comprises the rudder wing, rudder wing pop-up fixing blocks, rudder wing pop-up pins and a steering engine shell, a steering engine part is arranged in the steering engine shell, and four rudder wing pop-up fixing blocks are arranged between the outer side of the steering engine part and the steering engine shell; the rudder wing is fixed to the rudder wing pop-up fixing block, a rudder wing hiding groove is formed between the rudder wing and the steering engine shell, a rudder wing pop-up spring is arranged in the rudder wing pop-up fixing block, and the rudder wing pop-up pin is arranged at the position, located on one side of the rudder wing, of the rudder wing pop-up spring. A containing groove is formed between the rudder wing pop-up pin and the rudder wing pop-up fixing block. The rudder wing ejection pin and the rudder wing ejection spring are matched to eject out the rudder wing, so that it is guaranteed that the rudder wing can be rapidly unfolded after the steering engine shell is ejected out, follow-up operation is guaranteed, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of aircraft steering gear, in particular to a pop-up mechanism applied to the rudder wing of the aircraft steering gear. Background technique [0002] The aircraft steering gear is an important actuator to realize the attitude transformation motion of the aircraft such as pitch, yaw, and roll. The accuracy and precision of the aircraft steering gear transmission mechanism directly affect the flight trajectory accuracy and dynamic quality of the aircraft. Due to the advantages of high precision, high efficiency, small size, and light weight, the harmonic reducer has been widely used as a transmission mechanism in various aircraft steering gears, but its stiffness is low, and the flexible wheel and flexible bearing are prone to fatigue damage, etc. These shortcomings seriously restrict the development of high-precision and high-reliability aircraft in the future. [0003] However, the current aircraft steering gears ar...

Problems solved by technology

Due to the advantages of high precision, high efficiency, small size, and light weight, the harmonic reducer has been widely used as a transmission mechanism in various aircraft steering gears, but its stiffness is low, and the flexible wheel and flexible bearing are prone to fatigue damage, etc. Shortcomings, which seriously restrict the development of high-precision and high-reliability aircraft in the future

[0003] However, the current aircraft steering gears are all fixed rudder wings after launch, and the fixed rudder wings cannot adjust the attitude of the steering gear well due to space constraints, while increasing the rudder wings requires a good deployment structure
