Flying saucer type helicopter utilizing active airflow to generate lifting power

Abstract

The invention relates to a flying saucer type helicopter utilizing active airflow to generate lifting power. As everyone knows, the asymmetric airflow on the upper surfaces and lower surfaces of wings can generate lifting power, however for both a fixed wing aircraft and a propeller-driven aircraft, the wings move, the air is motionless, and airflow is passively generated. According to the invention, an opposite approach is chosen. Specifically, the wings are fixed, actively generated airflow flows through the upper surfaces of the wings, an air pressure difference is manufactured between the upper surfaces and lower surfaces of the wings so as to generate the lifting power, thus realizing a safe and simple aircraft that can achieve vertical take-off and landing, hovering, level flight and pivot steering. The appearance of the aircraft is similar to a flying saucer. By adjusting the angle between the airflow direction of the aircraft's upper surface and the radial direction, spin of the fuselage can be controlled, and by adjusting the flow velocity distribution of the front, back, left and right directions, the inclination direction of the aircraft body can be changed to realize level flight and direction control. The novel aircraft not only has all the advantages of traditional helicopters, but also has the characteristics of simplicity, compactness, safety, stability and the like, and is an ideal solution to one-man aircrafts and unmanned reconnaissance aerial vehicles.

Description

technical field [0001] The invention belongs to the field of aviation aircraft, in particular to a helicopter or a flying saucer aircraft capable of vertical take-off and landing, hovering and level flight. Background technique [0002] Compared with other means of transportation, the biggest advantage of a helicopter is that it can take off and land vertically and hover in the air, which makes it not need specific roads (relative to cars), airports (relative to fixed-wing aircraft), docks (relative to ships), tracks ( Compared with auxiliary facilities such as trains), it only needs a flat land slightly larger than the size of the fuselage to realize take-off and landing. That is to say, the geographical terrain basically does not constitute any restrictions on the use of helicopters. Helicopters can easily handle deserts and swamps, rivers, lakes and seas that can only be sailed by boats, or cities full of tall buildings. From this point of view, the helicopter is the mos...

Problems solved by technology

First of all, whether it is a single rotor, or a horizontal or tandem dual rotor, whether it is a coaxial reverse propeller helicopter or a tilt rotor aircraft, they all have a common feature, that is, the huge rotor, the exposed high-speed rotating rotor It is very unsafe to collide with any object. This structure greatly increases the requirements of existing helicopters on the openness of space, restricts the operation of helicopters in small spaces, and increases the unsafety of helicopters; secondly , the level flight of existing helicopters is mainly realized by the periodic variable pitch technology. This mechanical operation principle not only has...
