High-altitude long-endurance unmanned aerial vehicle with foldable telescopic wings

Abstract

The invention discloses a high-altitude long-endurance unmanned aerial vehicle with foldable telescopic wings, and relates to the technical field of aviation. The problems that an existing high-altitude long-endurance unmanned aerial vehicle occupies too large space during transportation and storage due to the fact that the wingspan is too large, the maintenance cost is high, and rapid deployment is difficult are solved. The unmanned aerial vehicle comprises a vehicle body, two front folding wings, two rear folding wings, two front telescopic wings, two rear telescopic wings, two folding empennages, two folding propeller blades, a plurality of folding mechanisms and a plurality of telescopic mechanisms, the front folding wings are symmetrically arranged on the two sides of the front end of the abdomen of the vehicle body respectively, and the front telescopic wings are inserted into the outer side ends of the front folding wings; the rear folding wings are symmetrically arranged on the two sides of the rear end of the top of the fuselage respectively, the rear telescopic wings are inserted into the outer side ends of the rear folding wings, the folding empennages are symmetrically arranged on the two sides of the rear portion of the fuselage respectively, and the two folding propeller blades are symmetrically arranged at the tail of the fuselage. The invention is used for the high-altitude long-endurance unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a high-altitude long-endurance unmanned aerial vehicle with foldable and telescopic wings. Background technique [0002] Due to its good aerodynamic performance and good fuel economy, high-altitude and long-endurance UAVs are suitable for long-term reconnaissance and surveillance tasks at high altitudes, and can be used as unmanned combat platforms. HMI has the characteristics of rapid deployment, easy maintenance, and low operating cost. However, the wingspan and large wing area of ​​general high-altitude and long-endurance drones will cause the drones to take up too much space during transportation and storage, which not only increases the difficulty of ground maintenance and transportation, but also increases operating costs. It is also difficult to deploy quickly. [0003] In order to solve this problem, consider adopting the method of folding and deforming the wings, so ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of the existing high-altitude and long-endurance drones, which lead to excessively large wingspan during transportation and storage, high maintenance costs, and difficulty in rapid deployment, the present invention proposes a high-altitude drone with foldable and telescopic wings. Long-endurance drones can change the length of the wings of the drone during storage and transportation. On the premise of ensuring sufficient wing area for high-altitude and long-endurance drones, they can be folded and folded into In the circular launch tube, not only the occupied volume is reduced, it is convenient for storage and transportation, but also the UAV can be quickly deployed by means of cannon fire or high-altitude drop, and you can also choose to launch the UAV at the right time
