Abstract

The invention discloses an aerodynamic layout of a supersonic silent unmanned aerial vehicle, comprising: a nose, two canards, side strips, two wings, an air inlet, a fuselage and two empennages; wherein, the nose and The front ends of the fuselage are connected, and the nose is a quasi-conical hollow cylinder that is upturned near the apex of the head and the nose has a downward inclination as a whole; two canards are arranged on both sides of the nose. side; the side strip is fused with the fuselage, and the side strip is located at the rear of the nose; two wings are arranged on both sides of the fuselage, and the wings are located on the side of the side strip rear portion; the back side of the fuselage is provided with an air inlet, and the air inlet is located at the rear of the wing; two empennages are arranged on both sides of the fuselage, and the empennage is located at the the end of the body. The invention solves the problem that there are still vacancies for hypersonic unmanned aerial vehicles flying in space.

Description

technical field [0001] The invention belongs to the field of aerodynamic layout design of unmanned aerial vehicles, and in particular relates to an aerodynamic layout of a supersonic silent unmanned aerial vehicle. Background technique [0002] In the Afghan operations from 2001 to 2002, the U.S. Predator UAV carried out the strike mission for the first time, becoming a milestone in the history of UAV development. During the Iraq War in 2003, the U.S. military deployed and used about 90 drones, mainly responsible for tactical reconnaissance, battlefield patrol and special target attack missions. U.S. drones played an important role in the air strikes on Libya. With the rapid development of high-tech military technology, unmanned military equipment has penetrated into almost every field of battlefield space. Unmanned aerial vehicles have become an important and even key force affecting the combat process and have been valued by more and more countries. The military departmen...
