Problems solved by technology

Because the aspect ratio of the rudder surface is large and the thickness is thin, if the horizontal folding method is adopted, not only the aerodynamic resistance will be greater, but also there will be a large bulge on the rudder surface, which will affect the performance of the rudder surface
At the same time, due to the limited internal space of the cabin, the general longitudinal folding method uses pyrotechnics as the power source for unfolding and transmits power through the connecting rod mechanism. Unable to meet its structural and exercise space requirements

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] The invention provides a rudder surface longitudinal folding mechanism, such as figure 1 , 2 , 3, and 4, including:

[0016] Folding rudder surface 1, fixed rudder surface 2, pin puller 5, lock in place 7, scroll spring 9, steering gear 4, tail compartment 6, rotating shaft 11 and bearing 3;

[0017] Install the steering gear 4 and the pin puller 5 in the tail compartment 6 respectively, then install the in-position lock 7 into the inner hole of the fixed rudder surface 2, and install the bearing 3 in the shaft hole of the folded rudder surface 1 through interference fit. The two sides of the tiller handle of the folding rudder surface 1 are connected to one end of a scroll spring 9 respectively; The other end is hooked on the fixed rudder surface 2, and the rotating shaft 11 penetrates the fixed rudder surface 2 and the inner hole of the bearing 3 ...

Abstract

The invention discloses a control surface longitudinal folding mechanism. According to the control surface longitudinal folding mechanism, a steering engine (4) and a pin puller (5) are mounted in a tail bin (6); an in-place lock (7) is mounted in an inner hole of a fixed control surface (2); a bearing (3) is mounted in a rotary shaft hole of a folding control surface (1) in an interference fit manner; the two sides of a tiller of the folding control surface (1) are each connected with one end of a volute spring (9); the folding control surface (1) provided with the bearing (3) and the volute springs (9) is placed in an inner groove of the fixed control surface (2); the other ends of the volute springs (9) are connected to the fixed control surface (2) in a hooked manner; a rotary shaft (11) sequentially penetrates in the inner hole of the fixed control surface (2) and an inner hole of the bearing (3) to connect the fixed control surface (2) with the bearing (3); and the fixed control surface (2) and the steering engine (4) are connected, then the folding control surface (1) is rotated to a folding position, a lock pin of the pin puller (5) is embedded in a square groove (8) of the folding control surface (1), and the folding control surface (1) is locked.

Description

technical field [0001] The invention relates to a rudder surface folding mechanism, in particular to a rudder surface longitudinal folding mechanism. Background technique [0002] In order to meet the platform mounting space requirements and increase the platform’s ammunition loading capacity, a certain type of missile needs to adopt a folding rudder surface to reduce the overall size and the space occupied by the missile. Because the aspect ratio of the rudder surface is large and the thickness is thin, if the horizontal folding method is used, not only the aerodynamic resistance of unfolding is relatively large, but also the rudder surface will have a large bulge, which will affect the performance of the rudder surface. At the same time, due to the limited internal space of the cabin, the general longitudinal folding method uses pyrotechnics as the power source for unfolding and transmits power through the connecting rod mechanism. It cannot meet its structure and exercis...
