Abstract

The invention discloses a four-duct flying-wing type unmanned aerial vehicle which comprises ducts, fans, winglets and a flying-wing type wing, wherein symmetric winglets are mounted on the tip of the flying-wing type wing; four duct fan power systems are mounted on the winglets respectively; and the fans are arranged in the ducts. The invention has the following effects: (1) the four-duct flying-wing type unmanned aerial vehicle has the advantages of fast cruise, vertical take-off and landing, hovering, low noise, autonomous flight and easiness in control; and (2) control of multiple attitudes can be realized, the control method is simpler with high flexibility and is more helpful to implementing specific tasks in complicated special conditions.

Description

technical field [0001] The invention relates to an aircraft, in particular to a four-duct flying-wing unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicles (UAVs) have extensive potential in the military application of combat reconnaissance in cities and complex terrain conditions, and have become a research hotspot in countries all over the world. In terms of military practicability, especially as a UAV for urban combat reconnaissance, it is required to be able to cruise quickly, take off and land vertically, have good maneuverability, hover, have low noise, fly autonomously, and be easy to control. [0003] Fixed-wing UAVs can achieve high-speed forward flight, but do not have the ability to vertically lift and hover; compared with propeller aircraft, ducted aircraft can generate greater pulling force under the same propeller diameter and power consumption. In addition, the duct improves the safety of the aircraft and reduces aerodynamic noise. ...
