Abstract

The invention discloses a folding steering engine, and belongs to the technical field of steering engines. The folding steering engine comprises a steering engine body, a rudder sheet control assembly and a rudder sheet locking assembly. The steering engine body comprises an engine body, a rotating shaft, at least one rudder sheet and a motor, the rotating shaft is rotatably arranged in the engine body, one end of the rotating shaft is provided with a slot axially extending along the rotating shaft, one side of the slot is provided with a limiting block, and the motor is located on the engine body. The rudder control assembly comprises a piston rod, a locking chuck and an initiating explosive device, one end of the piston rod is slidably inserted into the machine body and connected with the machine body through a snap pin, the piston rod is sleeved with a boss, and the locking chuck is located at the other end of the piston rod. The rudder piece locking assembly comprises a spring and a limiting pin, the two ends of the spring are connected with the limiting pin and the rotating shaft respectively, and the other end of the limiting pin abuts against the rudder piece. According to the folding steering engine provided by the embodiment of the invention, the unfolding rate of the rudder sheet can be greatly improved, and the unfolding stability of the rudder sheet can be ensured.

Description

technical field [0001] The invention belongs to the technical field of steering gear, and more specifically relates to a folding steering gear. Background technique [0002] In recent years, with the continuous progress of the basic industrial level and modern technology, the rudder system is developing towards the design direction of miniaturization, long life, high efficiency and maintenance-free. Research on technologies such as unmanned aerial vehicles and cruise-guided missiles in my country has become one of the current hot spots. Due to the small size of unmanned aerial vehicles and cruise guidance missiles, the utilization rate of internal space is extremely high, which increases the difficulty of designing and developing steering gear for adjusting their space attitude or engine control. The folding steering gear came into being. Compared with the traditional steering gear, on the basis of ensuring the performance of the traditional rudder system structure, the fol...
