The initial fixed unlocking scheme of the folding rudder generally comprises a fixed unlocking scheme by utilizing the cylinder wall constraint of the launching cylinder, a fire or electric action, and the like. For hypersonic speed cylinder-mounted aircrafts, a transverse folding scheme is usually preferred in consideration of structural bearing, heat protection and the like, and an initial fixing unlocking scheme is preferred to a scheme for restraining the cylinder wall of a transmitting cylinder in order to ensure unlocking reliability.

Detailed Description
The invention will be further described with reference to the drawings and examples.
The invention aims to provide a folding rudder unfolding and locking mechanism with small size and high torque under the condition that the size of the internal space of an air rudder is limited, and the unfolding and locking requirements of the folding rudder are met through simple and reliable mechanism design.
The invention provides a small-size high-torque folding rudder unfolding and locking mechanism which mainly comprises a fixed control surface, a movable control surface, a front rotating shaft, a rear rotating shaft, a torsion piece group, a torsion piece limiting seat, a torsion piece mounting pin, a front locking pin rear locking pin, a front locking pin pressure spring, a rear locking pin pressure spring, a limiting square key, a blocking cover and the like.
The fixed control surface is connected with the servo cabin body and the servo steering engine, and the movable control surface is driven by the folding and locking mechanism, so that the deflection of the whole air rudder according to the control instruction is realized. The fixed control surface and the movable control surface are connected through a front group of rotating matching surfaces and a rear group of rotating matching surfaces.
The movable control surface uses the torsion sheet group as a unfolding power source, the front end of the torsion sheet group is connected with the fixed control surface, and the rear end of the torsion sheet group is connected with the movable control surface through the torsion sheet limiting seat. When the control surface is in a folded state, the front end of the torsion sheet group is not moved, and the rear end of the torsion sheet group rotates along with the control surface, so that the torsion sheet group generates torsion deformation in an elastic range.
The torsion center of the torsion sheet group is coaxial with the centers of the front rotating shaft and the rear rotating shaft, and the rear end of the torsion sheet group can not rotate relative to the movable control surface, but can generate smaller axial direction, so that the torsion sheet group is ensured to bear torsion deformation load only when the movable control surface is folded, and no other forms of load exist. Further, the size and the number of the torsion plate groups need to be calculated and determined according to the moment of inertia of the control surface and the unfolding time.
The locking pin has the function of being locked reliably when the movable control surface is unfolded in place and is inserted into the fixed control surface. Further, the locking pin is prevented from being locked in place due to processing and assembly errors, and the locking part of the locking pin is designed to be conical. Further, in order to facilitate the folding of the control surface, a process threaded hole is arranged at the tail part of the rear locking pin, so that the unlocking of the locking pin is facilitated.
The functions of the front locking pin pressure spring and the rear locking pin pressure spring are to provide power for the pin-in of the locking pin, and when the movable control surface is not unfolded in place, the front locking pin pressure spring and the rear locking pin pressure spring are in a compressed state.
The front rudder shaft points to the direction of the front edge of the rudder, and the back rudder shaft points to the direction of the front edge of the rudder; the upper part is the rudder root chord pointing to the direction of the minor chord, and the lower part is the opposite; left is left as seen from the rudder trailing edge to the leading edge, and vice versa.
In summary, the main working principle of the folding rudder unfolding and locking mechanism provided by the invention is as follows: the fixed control surface and the movable control surface are connected through a front rotating shaft and a rear rotating shaft, and a torsion sheet group is designed in the rotating shaft; when the control surface is in a folded state, the torsion sheet group is subjected to torsion deformation in an elastic range, at the moment, the front locking pin and the rear locking pin are propped against the front matching surface and the rear matching surface of the fixed control surface, and the locking pin compression spring is in a compressed state; after external constraint is released, the movable control surface can rotate under the drive of the torsion sheet group, and when the movable control surface rotates to the front ends of the front locking pin and the rear locking pin start to be pinned into the front locking pin hole and the rear locking pin hole of the fixed control surface, the front locking pin and the rear locking pin are rapidly popped up under the action of the pressure spring, so that the unfolding and locking of the folding rudder are realized.
