Abstract

The invention discloses a ducted propeller aircraft, wherein a lift system formed by ducted coaxial twin propellers is used as a main lift surface of the aircraft, so as to overcome the weight of theself-structure and the hanging load. Four ducted propellers located around the control surface can be used to control the yaw pitch and roll of the vehicle through the differential speed of the propeller. At the same time, they can also provide part of the lift for the aircraft. Compared with some existing ducted fan vehicles controlled by control rudder surface, it has the advantages of simple and reliable control, high control efficiency and good stability.

Description

technical field [0001] The present invention relates to the technical field of aircraft, and more specifically relates to a ducted propeller aircraft. Background technique [0002] Ducted unmanned aerial vehicles usually refer to those special aircraft that use ducted fans as the main power system and fuselage structure of the aircraft. This type of aircraft can not only achieve vertical take-off and landing, but also has good hovering performance. It is precisely because of its special body structure that it has incomparable advantages over traditional unmanned aerial vehicles. This type of unmanned aerial vehicle is not only light in weight, small in size, low in cost, and easy to operate, but also relies on its compact body structure and automatic flight control. The system can effectively complete tasks in various complex environments by mounting various small airborne equipment, which makes it of inestimable application value in military, civilian and scientific researc...
