The invention discloses a
low noise cartridge receiver and control plane for duct type vertical take-off and landing air vehicle. The
cartridge receiver is divided into a lip ring, a
cartridge receiver main body and a sawtooth bottom ring which are sequentially arrayed from top to bottom and are connected and fixed by virtue of long bolts and nuts through four screw holes;
tail guiding control planes are mounted on the inner side of the sawtooth bottom ring, and triangular sawteeth are arranged on the
tail edges of the
tail guiding control planes; and the sawteeth at the tail of the sawtooth bottom ring are of a sine form, and the end surfaces the sawteeth are vertical to the cylindrical surface on the inner side of the cartridge receiver. After the cartridge receiver is processed, the cartridge receiver main body is capable of effectively absorbing
noise produced by propellers; the structure of a speed shearing layer is influenced by the sawtooth bottom ring, so that the jet
noise ofthe duct air vehicle can be effectively reduced; and by utilizing the sawtooth structures at the tail edges of the tail guiding control planes, the tail track region is broadened, the crushing of trailing vortex is accelerated, and the
noise of turbulent flow behind the control planes is effectively lowered. Compared with a traditional multi-rotor duct air vehicle, the air vehicle utilizing the cartridge receiver and the control plane is relatively quiet during the flight, can be used for executing tasks with high concealing requirements and has wide application prospects.
