specific Embodiment approach 1

[0019] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment, this embodiment comprises folding propeller 1, fuselage 2, left rear wing 3, right rear wing 4, left front wing 5, right front wing 6, two vertical empennages 7, two vertical empennage pin shafts 8 and four A rotating hinge 9, folding propeller 1 is installed on the head of fuselage 2, arranges like this to be conducive to the ejection launch of flying robot, left front wing 5 and right front wing 6 are symmetrically arranged on both sides of fuselage 2 front ends, left rear wing 3 and The right rear wing 4 is symmetrically arranged on both sides of the rear end of the fuselage 2, and the left front wing 5, the right front wing 6, the left rear wing 3 and the right rear wing 4 are respectively hinged with their corresponding rotary hinges 9, and each rotary hinge 9 is connected to the fuselage. 2. The corresponding steering gear is connected inside (the hinge 9 is driven by the ste...

specific Embodiment approach 2

[0021] Specific implementation mode two: combination Figure 4 The present embodiment will be described. The left front wing 5 and the right front wing 6 of the present embodiment are rotated forward by 0° to 90° from a position parallel to the fuselage 2 . Such an arrangement can ensure rapid and accurate deployment of the wings of the flying robot and that the front wings can only be swept back during flight, thereby reducing the complexity of the control of the flying robot. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0022] Specific implementation mode three: combination figure 2 The present embodiment will be described. The left rear wing 3 and the right rear wing 4 of the present embodiment are rotated backward by 0° to 90° from a position parallel to the fuselage 2 . This arrangement can ensure that the wings of the flying robot can be deployed quickly and accurately, and that the rear wing can only be swept forward during flight, thereby reducing the complexity of the control of the flying robot. Other components and connections are the same as those in the second embodiment.

[0023] Working principle of the present invention:

[0024] (1) Before the flying robot ejects and takes off, each wing rotates to a position parallel to the fuselage 2, see figure 1 and figure 2 ;

[0025] (2) After the flying robot is ejected, the left front wing 5 and the right front wing 6 are fully deployed after turning forward 90° under the driving of the steering gear; the left rear wing 3 and the ...

Abstract

A variable grazing angle catapult tandem wing flying robot, in order to solve the problem that the two front folding wings and the two rear folding wings of the existing catapult flying robot cannot be unfolded separately, which limits the motion attitude control of the flying robot question. The present invention comprises folding propeller, fuselage, left rear wing, right rear wing, left front wing, right front wing, two vertical empennages, two vertical tail pins and four rotary hinges, and the folding propeller is installed on the head of the fuselage , the left front wing and the right front wing are symmetrically arranged on both sides of the front end of the fuselage, the left rear wing and the right rear wing are symmetrically arranged on both sides of the rear end of the fuselage, and the left front wing, right front wing, left rear wing and right rear wing correspond to them respectively Each rotating hinge is connected to the corresponding steering gear inside the fuselage. Two vertical tail fins are symmetrically arranged on both sides of the tail end of the fuselage, and the vertical tail fins are installed on the upper surface of the tail end of the fuselage through torsion springs. . The invention is used for attitude control of flying robots.

Description

technical field [0001] The invention relates to a catapult flying robot, in particular to a catapult tandem wing flying robot with variable grazing angle. Background technique [0002] At present, the catapult flying robot has been favored by the majority of researchers due to its high launch speed, good launch stability, and ability to launch in complex terrain. At the same time, the wings of the catapult flying robot can be folded, which is convenient for transportation and storage. Usually, the control method of flying robots is to use ailerons and tail rudders to realize its roll and pitch attitude control. However, due to the wing folding characteristics of catapult folding wing flying robots, this method will make the folding structure more complicated and the number of parts increase, the failure rate is also relatively high. At the same time, for the tandem wing layout, if two ailerons are used to control, the control force generated is small and the response speed ...
