Flying wing arrangement hidden unmanned aerial vehicle

Abstract

The invention belongs to the technical field of air vehicles and discloses a flying wing arrangement hidden unmanned aerial vehicle. The flying wing arrangement hidden unmanned aerial vehicle comprises a vehicle body. A first equipment cabin is arranged on the middle portion of the vehicle body, and oil tanks are arranged on the two sides of the first equipment cabin; and a second equipment cabinis integrally arranged at the front end of the vehicle body, centrally-controlled air inflow channels are arranged on the two sides of the second equipment cabin, the rear ends of the air inflow channels communicate with exhaust nozzles, and the exhaust nozzles are arranged on the rear side of the vehicle body. The flying wing arrangement hidden unmanned aerial vehicle has the beneficial effects that flying wing arrangement is adopted to improve the smoothness and simpleness of the whole appearance, and the unmanned aerial vehicle has good hidden performance and small friction resistance; wings with spanwise variable airfoil profiles are adopted to improve the aerodynamic efficiency of the unmanned aerial vehicle, and the unmanned aerial vehicle has the large cruise lift-drag ratio and high-efficiency balancing capacity; and the wings with multiple sections of different spanwise anhedral angles are adopted to improve the flight quality of the unmanned aerial vehicle, and the unmanned aerial vehicle has good lateral-direct maneuverability and stability.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a stealth unmanned aerial vehicle with a flying wing layout. Background technique [0002] The aerodynamic layout of the current unmanned aircraft usually adopts a conventional layout, that is, the wings are in front to provide the main lift, and the horizontal tail and vertical tail are behind to provide maneuverability and stability. However, due to the large number of aerodynamic components and the unfavorable interference between the components in the conventional layout, the waste resistance of the aircraft increases, thereby reducing the cruise lift-to-drag ratio. For military drones, under the irradiation of radar waves, the unfavorable scattering between more aerodynamic components will greatly enhance the radar reflection signal of the whole aircraft and reduce the stealth performance.

AI Technical Summary

Problems solved by technology

[0004] In summary, the existing problems in the prior art are: due to the lack of horizontal and vertical tail fins in the flying wing layout aircraft, there are relatively large defects in the maneuverability and stability of the whole aircraft.

In particular, it is easy to enter the lateral heading instability state where the Dutch roll diverges

Therefore, the flying wing layout aircraft is facing huge challenges in terms of flight quality and flight safety.
