Problems solved by technology

[0002] Traditional flexible wing platforms mainly include flexible wings, airframes, etc. Among them, the flexible wing, as a mechanism for generating lift, can be divided into round umbrella and parafoil. Poor, the parafoil has the function of controlling the platform, but its actuator, that is, the steering gear, needs to pull the paracord, and the general layout is relatively large. For platforms with size restrictions, the contradiction between size constraints and autonomous flight is difficult to solve

Embodiment 1

[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 The shown long-endurance flexible wing controllable platform includes a cylindrical body 1 and a flexible parafoil 19. The body 1 includes an umbrella cabin 9 that can be separated from the body under the control of the flight control system. In the umbrella cabin 9 and connected to the body 1 by the umbrella rope 20; the umbrella rope 20 and the body can be connected by the ring screw 11;

[0026] The body is provided with a cutting surface 22, and the cutting surface 22 is provided with two power arms 3, a fixed structure 4 for folding and limiting the power arms 3, and driving the power arms to expand. The rotating mechanism 2 for locking the power arm;

[0027] The far end of the power arm 3 is provided with a motor 6 controlled by the flight control system and a propeller 7 driven by the motor 6 to rotate.

[0028] The flight control system is the core of the entire flexible wing platform, which controls the ...

Embodiment 2

[0031] Such as figure 1 , figure 2 As shown, the body structure of this embodiment is optimized on the basis of the foregoing embodiments, that is, the body includes a top-down umbrella cabin, a flight control cabin 12, a power cabin 16 and a load cabin 18, and two adjacent cabins Separated by a partition 15 with holes, the flight control system is arranged in the flight control cabin, and the power cabin is provided with a power system that provides electric energy for the flight control system and other electronic equipment such as loads. The setting with holes on the partition facilitates the setting of the connection lines between the various systems.

[0032] The flight control system is connected with the power system 17 and the signal receiving system. The signal receiving system includes a GPS antenna 10 and a chain antenna. The signal receiving system is placed in the umbrella cabin.

[0033] Such as image 3 As shown, the rotating mechanism 21 includes a torsio...

Abstract

The invention discloses a long-endurance flexible wing controllable platform, which includes a body and a flexible parafoil. The body includes an umbrella cabin that can be separated from the body under the control of a flight control system. In the cabin and connected to the body through parachute ropes; the body is provided with a cut surface, and the cut surface is provided with two power arms, a fixed structure for folding and limiting the power arms, and driving the power arms to expand and the two power arms to unfold A rotating mechanism that locks the power arm when it reaches a straight line; the far end of the power arm is provided with a motor controlled by the flight control system and a propeller that rotates under the drive of the motor; it itself has better controllability, power The dual-motor differential control of the arm provides the steering ability for the platform to realize the autonomous flight of the platform.

Description

technical field [0001] The invention relates to the field of flexible-wing platforms, in particular to a long-endurance flexible-wing controllable platform that flies autonomously, is suitable for missile delivery, and stays in the air for a long time. Background technique [0002] Traditional flexible wing platforms mainly include flexible wings, airframes, etc. Among them, the flexible wing, as a mechanism for generating lift, can be divided into round umbrella and parafoil. Poor, the parafoil has the function of controlling the platform, but its actuator, namely the steering gear, needs to pull the paracord, which is generally arranged in a large size. For platforms with size restrictions, the contradiction between size constraints and autonomous flight is difficult to solve. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a long-endurance flexible wing controllable platform. [0004] The present inventi...
