Abstract
The utility model discloses a kind of external rudder faces using flexible, hinged, including rudder face, flexible hinge and airfoil structure, when rudder face rotates inelastic deformation only occurs for flexible hinge, can solve loss of lift and airfoil structure and energy loss caused by rudder clearance caused by when general built-in rudder face rotates.The utility model is a kind of high lift device for aircraft raising pneumatic efficiency, while reduces production difficulty, maintains easily.
Description
Technical field
The utility model belongs to technical field of aircraft design, and in particular to a kind of external rudder face using flexible, hinged.
Background technology
For general aircraft, the gesture stability of pitching, rolling and the yaw of aircraft depends mainly on rudder face.
In conventional airfoil structure structure, rudder face is placed in airfoil structure, and the connection of rudder face and airfoil structure is completed by hinge.It is such
Structure so that between airfoil structure and rudder face that there are gap fluid can generate vortex when passing through aerofoil, cause energy loss.It is such
Built-in rudder face during rotation is driven, changes the lift coefficient of airfoil structure, completes the posture conversion of aircraft.In addition
A kind of seamless rudder face technology using flexible flexible structure, realizes the rotation of rudder face, but the bearing capacity of rudder face is poor, should
With not extensively.
Utility model content
Loss of lift caused by during to solve general built-in rudder face rotation and airfoil structure and energy caused by rudder clearance
Loss, the utility model provide a kind of external rudder face using flexible, hinged.
To solve the above problems, the technical solution of the utility model is：A kind of external rudder face using flexible, hinged,
Including rudder face, flexible hinge and airfoil structure, the rudder face further includes the rudder angle for being fixed on rudder face bottom part body, the aerofoil knot
Structure further includes steering engine and transmission shaft, and the rudder face is fixedly connected on the rear rafter of the airfoil structure by the flexible hinge, with
The rear rafter of the airfoil structure is moved for shaft rotation, and when the rudder face rotates inelastic deformation only occurs for the flexible hinge.
Preferably, which is made of carbon fibre material.
Preferably, the material of the flexible hinge is has sticking macromolecular fibre.
The steering engine installed on the airfoil structure pulls the rudder angle of the rudder face bottom by transmission shaft so that rudder face occurs
Rotation, at steering engine neutral position, transmission shaft is parallel to rudder face, the connecting line perpendicular to rudder face and airfoil structure rear.
Preferably, which is a kind of driver of position (angle) servo.
Preferably, one or more steering engines and transmission shaft can be installed on the airfoil structure, corresponds the rudder face
On one or more rudder angles.
Preferably, the transmission shaft is metal material.
Preferably, the transmission shaft further includes the attachment device with steering engine and rudder angle.
Rudder face is placed on the outside of airfoil structure in the utility model, is not interfered with the lift coefficient of airfoil structure, be ensure that winged
The loading capacity of row device；Stiff flexible material covers the gap of rudder face and airfoil structure, avoids the energy loss at this.This
A kind of external rudder face using flexible, hinged that utility model is related to enormously simplifies the production technology of airfoil structure and rudder face,
Improve production qualification rate；Simultaneously during the use of aircraft, this rudder face is easy to maintain, adaptable.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Rudder face 10 described in Fig. 1 and Fig. 2 includes the rudder angle 11 for being fixed on 10 bottom part body of rudder face, and the airfoil structure 30 wraps
Containing steering engine 31 and transmission shaft 32.
The flexible hinge 20 is pasted on rudder face 10 and the upper surface of airfoil structure 30 and rudder face 10 and airfoil structure respectively
30 lower surface so that rudder face 10 is fixed on the rear rafter of airfoil structure 30.
The steering engine 31 and 32 nested encryptions of transmission shaft, transmission shaft 32 are fixed with rudder angle 11 with bolt.
Steering engine 31 described in Fig. 3 can pull transmission shaft 32 after being powered, and transmission shaft 32 pulls rudder angle 11, realize rudder face 10 with
Rafter is moved for shaft rotation after airfoil structure 30.During rudder face 10 rotates, inelastic deformation occurs for flexible hinge 20.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but not to this practicality newly
The limitation of type protection domain, those skilled in the art should understand that, on the basis of the technical solution of the utility model, ability
Field technique personnel would not require any inventive effort the various modifications or changes that can be made still in the protection of the utility model
Within the scope of.
