Embodiment 1

[0062] see image 3 , Figure 4 , the limiting component is a vertical plate 7;

[0063] The limiting portion is provided in the vertical plate 7 with the same number of piercing holes as the number of lifting rods. Each lifting rod 3 is pierced in a piercing hole, and the lifting rods 3 and the piercing holes are all clearance fit. The bottom of the vertical plate 7 is fixed on the aircraft body 1, the driving parts 4 and the controller 5 are all arranged in the inside of the aircraft body 1, the upper wing 6 is an axisymmetric structure, and the axis of symmetry is positioned on the vertical plane passing through the central axis of the aircraft body , Riser 7 is arranged on upper wing 6 bottom and is arranged along this vertical plane, and perforation hole is arranged along the vertical direction of riser, like this, can guarantee that elevating rod 3 can only move in vertical direction.

[0064] In embodiment one:

[0065] The quantity of elevating rod 3 can be set acco...

Embodiment 2

[0071] see Figure 5 , Figure 6 , the limiting part includes two supporting bases 9; the two supporting bases 9 are fixed on the aircraft body 1, and the limiting part includes at least one guide rail 91 arranged on the supporting base 9 and at least one guide groove 32 arranged on the elevating rod 3 The number of guide rails 91 and guide grooves 32 is the same, and the shape of guide rails 91 is adapted to the shape of guide grooves 32 ; guide rails 91 are inserted or partially inserted into guide grooves 32 . The longitudinal direction of the guide groove 32 is arranged in a straight line along the axial direction of the lifting rod 3 .

[0072] In embodiment two:

[0073] The cross section of the guide groove 32 is dovetail, circular, elliptical, trapezoidal or T-shaped.

[0074] In the following, a simple two-dimensional configuration is used to test the influence of the change of the position of the upper wing on the aerodynamic performance of the aircraft when the f...

Abstract

The invention relates to an upper wing adjusting device and a high-speed aircraft. The upper wing adjusting device comprises at least a lifting poker, a driving element and a controller, wherein the lifting poker is used for connecting the driving element and the upper wing and driven by the motion of the driving element to lift up and down; the driving element is connected with the controller and drives the lifting poker to motion and lift up and down with a certain height under the action of the controller; the input end of the controller is connected with a control device of the aircraft; the output end is connected with the driving element; the controller outputs control signals according to the input signals from the control device of the aircraft, and outputs the control signals to the driving element. When the flight state is changed, the controller reads in flight parameters through the control device and obtains the lifting range of the lifting poker; the upper wing height can be adjusted through the driving element to avoid the safety problem triggered by the situation that when the flight state is changed, the shock waves of the aircraft body are crossed with the upper wing; the position of the upper wing can be controlled to obtain a better aerodynamic performance of the whole aircraft.

Description

technical field [0001] The invention relates to high-speed aircraft technology, in particular to an adjustable device with upper wings and a high-speed aircraft. Background technique [0002] High-speed aircraft mainly refers to various types of supersonic or hypersonic aircraft. Generally, the flight whose Mach number M is 1.2-5.0 is called supersonic flight; the flight whose Mach number M is greater than 5.0 is called hypersonic flight. The shock wave and boundary layer of the hypersonic flow have strong interference, which makes the analysis more complicated. Due to the strong compression of the airflow at the leading edge of the aircraft, a shock layer with a temperature of several thousand degrees Celsius will appear. Such a high temperature will make the surrounding The air molecules decompose and even ionize, which brings many new problems to the design and manufacture of aircraft. [0003] The configuration design of new high-speed aircraft is a hot issue in aircra...
