Helicopter capable of takeoff and landing by utilizing wind gathering disc

Abstract

The invention relates to the field of aerodynamics, in particular to a helicopter capable of takeoff and landing by utilizing a wind gathering disc. According to the technical scheme, the helicopter capable of takeoff and landing by utilizing the wind gathering disc comprises a helicopter body, a lift device, a power device, a transmission system and an outer propeller, wherein the lift device comprises the wind gathering disc and an inner propeller, the wind gathering disc is positioned at the bottom of the helicopter body, a hole is formed in the top of the wind gathering disc and is connected with the top of the helicopter body, the inner propeller is positioned in the wind gathering disc and is connected with the power device through the transmission system, the outer propeller is connected with the power device through the transmission system, a closing door is positioned below the wind gathering disc and is connected with the helicopter body. The helicopter has the beneficial effects that the helicopter capable of takeoff and landing by utilizing the wind gathering disc is used for replacing a conventional helicopter which is driven to take off and land and fly through rotating of large propellers, the flight speed of the helicopter can be increased, the flight of the helicopter can be increased, and the energy consumption of the helicopter can be reduced.

Description

technical field [0001] The invention relates to the field of aerodynamics, in particular to a helicopter that takes off and lands with a wind gathering disk. Background technique [0002] At present, helicopters are used in daily transportation, rescue and military affairs. The current helicopters use the power system to drive the large propeller to rotate, exert downward force on the atmosphere, and then use the reaction force of the air to make the aircraft rise. At the same time, the power unit also outputs power to the external small propeller to offset the large propeller The reaction force produced by the propeller in operation. The large propeller changes the angle of the blades through the swash plate to realize the way of changing the flight attitude and forward flight. Because the rotating area of ​​the large propeller of the existing helicopter is very large, the resistance of the whole machine is too large during ascent and flight, so the flight speed is low an...
