Problems solved by technology

[0003] At present, there are two main ways for aircraft to take off vertically, one is a structure similar to a helicopter, and the other is to realize the transition from vertical takeoff to level flight by rotating the thrust direction of the engine, similar to the American Osprey rotary wing aircraft or British Harrier fighter jets, the flying speed of the former method is relatively slow, while the latter method has a complex rotating mechanism and a heavy structural weight

Embodiment 1

[0039] Such as figure 1 , 2 , a kind of lift device for aircraft, it is installed on the aircraft, is connected with power source, and can produce the airflow that blows over the upper surface of aircraft wing 2, in this embodiment the lift device is propeller 3, and it is installed on the aircraft On the wings 2 on both sides of the body 1 (in this embodiment, the number of wings 2 is two, symmetrically arranged on both sides of the fuselage 1), the number of propellers 3 positioned on the same side of the fuselage 1 is equal to or greater than two (in this embodiment There are two in the example), generate forward and backward airflows on the upper surface of the wing 2 respectively, and the propeller 3 that produces the forward airflow is located in front of the other propeller 3, so that the two propellers 3 produce respectively The front airflow and the backward airflow do not interfere with each other, and the inclination angle of the 3 shafts of the propeller is adjust...

Embodiment 2

[0046] Such as image 3 , 4 , a kind of lift device for aircraft, it is installed on the aircraft, is connected with power source, and can produce the airflow that blows over the upper surface of aircraft wing 2, in this embodiment the lift device is propeller 3, and it is installed on the aircraft On the wings 2 on both sides of the body 1 (in this embodiment, the number of wings 2 is four, symmetrically arranged on both sides of the fuselage 1, and the wings 2 on the same side are arranged in parallel with each other at the same height), located at the same height as the fuselage 1. The number of propellers 3 on the side is equal to or greater than two (two in this embodiment, and different from Embodiment 1, these two are respectively arranged on different wings 2), respectively on the wing 2 upper surface to generate forward and backward airflow, in the present embodiment, because the propellers 3 with different functions are respectively arranged on different wings 2, th...

Embodiment 3

[0053] Such as Figure 7 , 8 , a kind of lift device for aircraft, it is installed on the aircraft, is connected with power source, and can produce the airflow that blows over the upper surface of aircraft wing 2, in this embodiment the lift device is propeller 3, and it is installed on the aircraft On the wing 2 on both sides of the body 1 (in this embodiment, the number of the wings 2 is four, symmetrically arranged on both sides of the fuselage 1, and the wings 2 on the same side are arranged in parallel to each other at different heights, which are up and down in this embodiment. Alignment), the number of propellers 3 located on the same side of the fuselage 1 is equal to or greater than two (two in this embodiment, installed on different wings 2), generating forward and backward on the upper surface of the wing 2 respectively Because the two propellers 3 are staggered up and down, the forward airflow and the backward airflow produced by the two propellers 3 do not interf...

Abstract

A lift device for aircraft and a take-off method using the lift device. The lift device is connected with a power source, which can generate an airflow that blows over the upper surface of the aircraft wing (2), through which the airflow generates lift to the wing (2) to make the aircraft fly, and the aircraft can be vertically lifted, or the aircraft can A state that moves slowly relative to the horizontal movement of the ground. The lift device can also have a relatively fast flight speed in a take-off state, has a simple structure and is light in weight.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a lift device for an aircraft and a take-off method using the device. Background technique [0002] Vertical take-off means vertical lift. The flight of an aircraft is divided into three main stages, namely take-off, level flight and landing. The way the aircraft takes off and lands is the taxiing method, so the airport runway is needed, and the vertical take-off and landing mainly refers to that the aircraft can It can take off vertically and land vertically on the spot without using a runway, and can not use an airport runway, which can reduce the cost of airport construction, and can also adapt to the take-off of aircraft in small spaces. [0003] At present, there are two main ways for aircraft to take off vertically, one is a structure similar to a helicopter, and the other is to realize the transition from vertical takeoff to level flight by rotating the thrust direction of the engi...
