Problems solved by technology

[0003] At present, the folding wings at home and abroad mainly adopt the horizontal folding method and the axial folding method. These two methods can reduce the diameter of the aircraft, but they are only suitable for aircraft with a relatively small aspect ratio. The longitudinal folding technology has already been used in the field of

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0024] The embedded folding mechanism of the present invention is mainly composed of a seat body, a torsion spring, screw pins, gaskets, leaf springs, cylindrical pins, pin nuts, fins or rudder blades. This mechanism folds manually and unfolds automatically. In the folded state, the diameter is 3mm larger than the diameter of the cabin body. Put the folded part larger than the projectile diameter by 3mm into the corresponding guide groove of the launch tube, which is used for the axial positioning of the aircraft launch, and ensures that the wings (rudders) are folded in place. Utilize the torsion force of the torsion spring to make the wing (rudder) unfold instantly to ensure the aerodynamic characteristics of the rudder.

Abstract

The invention provides an embedded folding wing mechanism which comprises a wing piece or a rudder piece, a seat body, a torsional spring, a screw pin, a plate spring and a cylindrical pin, and the seat body is connected with an aircraft cabin; the wing pieces or the rudder pieces are hinged to the base body through cylindrical pins, rotate around the axes of the cylindrical pins and retract intoaxial grooves in the outer wall of the aircraft cabin body or are unfolded in the radial direction of the aircraft cabin body. One end of the torsional spring is connected with the seat body through ascrew pin, and the other end is connected with a cylindrical pin to provide power for outward rotation of the wing or rudder from the aircraft cabin; the plate spring is installed on the seat body, the plate spring is located between the wing piece or the rudder piece and the seat body when the wing piece or the rudder piece retracts into the outer wall of the aircraft cabin body, the wing pieceor the rudder piece extrudes the warping face of the plate spring to deform, the plate spring rebounds after the wing piece or the rudder piece is unfolded and abuts against the side face of the wingpiece or the rudder piece, and in-place unfolding is guaranteed. A longitudinal folding scheme is adopted, the structure is exquisite, the response speed is high, and good strength, rigidity, shock resistance and installation precision are achieved.

Description

technical field [0001] The invention belongs to the technical field of testing and testing, and relates to an aircraft folding wing. Background technique [0002] In recent years, the design technology of folding wing (rudder) surface has been widely used in various aircrafts. In order to adapt to this situation, it is necessary to study the corresponding folding mechanism to make the wings (rudders) fold axially and then put them into the launch tube (box). During storage and transportation, the folded wings (rudders) of the aircraft are in a folded state. After launching out of the barrel, the wing (rudder) surface will automatically unfold to the working position through the action of the folding and unfolding mechanism, and retracted by the locking mechanism, so as to ensure the stability of the flight after the barrel is released. [0003] At present, the folding wings at home and abroad mainly adopt the horizontal folding method and the axial folding method. These two...
