Abstract

The invention provides an unmanned aerial vehicle using distributed ducted power and capable of short-distance take-off and landing and relates to the technical field of unmanned aerial vehicles. Theunmanned aerial vehicle has two fuselages. A front wing connects and traverses the fronts of the two fuselages, and a rear wing connects and traverses the tail portions of the two fuselages. Verticaltail wings are respectively installed directly above the tail portions of the two fuselages. An oil-electricity hybrid power scheme is adopted to prolong endurance of the unmanned aerial vehicle, andreduce weight, vibration and the oil consumption rate of a power system. Ducted power assemblies distributed on the upper surfaces of trailing edge flaps of the wings suction boundary layer airflow onthe upper surfaces of the wings so as to increase the aerodynamic efficiency of the wings. Distributed arrangement of the power system avoids a problem that malfunction of one engine causes a runawayunmanned aerial vehicle, thus improving safety of the unmanned aerial vehicle. The trailing edge flaps drive the ducted power assemblies to deflect so as to change a thrust direction, thus shorteningsliding distances in take-off and landing stages of the unmanned aerial vehicle, improving take-off and landing performance of the unmanned aerial vehicle, and expanding the application range of theunmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a short-distance take-off and landing unmanned aerial vehicle. Background technique [0002] At present, the power forms of drones are mainly divided into two types: oil-powered and electric. Oil-powered drones have a long battery life, but the weight, vibration and noise of the engine are very large, and the exhaust gas will pollute the environment. Electric drones are green, clean, light in weight and low in noise, but limited by the current level of battery technology, the power of the power system is small and the battery life is short. In addition, most drones currently use a single engine. The engine is installed at the nose or tail of the fuselage. The redundancy of the power system is low. Once a failure occurs, it is easy to cause the drone to lose control and crash. In order to solve the above problems, the existing patent technology such as the Chines...
