CN107554754A - A kind of aircraft lift（Or thrust）Device - Google Patents

Abstract

The present invention relates to a kind of aircraft lift (or thrust) device, particularly small size, larger lift unit；This device is tubbiness, shallow tubbiness or ware shape, built-in flabellum, and lift (or thrust) is produced by rotating, and its is compact-sized, is different from the lift unit of existing aircraft, makes it possible following transatmospheric vehicle miniaturization popularization.

Description

A kind of aircraft lift (or thrust) device

Technical field：

The present invention relates to a kind of aircraft lift (or thrust) device, particularly small size, larger lift unit, contribute to The miniaturization of aircraft.

Background technology：

With the continuous development of society, the land transportation that can't bear the heavy load can not increasingly meet the trip requirements of the mankind； Currently, or numerous aircraft use level wings, or using external propeller, there is many particular/special requirements to use condition, The shortcomings that unconquerable be present, be not suitable with the change of tomorrow requirement.In order to greatly develop air traffic, there is an urgent need to a kind of external form It is compact, relatively low transatmospheric vehicle is required to environmental condition.

The content of the invention：

In order to realize above target, its difficult point is the miniaturization of lift unit.The present invention just overcomes above difficulty very well, This device has a tubbiness, shallow tubbiness or ware shape shell 1, and outer casing bottom is closed, and top is into openning shape；On bucket (ware) inner bottom surface around Central axis is uniformly arranged several pieces air draft flabellums 2, the lower edge of flabellum 2 be close to inner bottom surface be connected as a single entity with inner bottom surface or from Inner bottom surface, side edge is close to bucket (ware) inwall or is connected as a single entity with bucket (ware) inwall, along consistent in the height and bucket of blade.

Brief description of the drawings：

Fig. 2 front views

Fig. 3 A-A sectional views

1 in Fig. 1：Shell；2：Flabellum

Shell plays a part of to protect and supports flabellum and connect drive device outside, and the effect of flabellum is excluded in bucket (ware) Gas, both, which are incorporated in, completes the function of producing lift (or thrust) under the driving of external driver device.

Embodiment：

When device ceaselessly rotates around direction of the central shaft along the air draft of flabellum 2, the gas in bucket (ware) is in flabellum 2 Ceaselessly it is discharged under effect, makes the gradual step-down of air pressure inside, external pressure is that atmospheric pressure keeps constant, inside and outside so as to produce Bottom surface pressure difference, just generated on bucket (ware) bottom plate it is upward lift power, this lifts power and rotating speed, flabellum, base areas size Relevant etc. factor, if the selection of each parameter is proper, lift power just can produce lift-off more than gravity.

Claims (2)

1. A kind of 1. aircraft lift (or thrust) device, it is characterised in that：Including tubbiness, shallow tubbiness or ware shape shell and built-in row Fan leaf；Wherein, the outer casing bottom is closed, open top；The air draft flabellum, around central axis on bucket (ware) inner bottom surface Uniformly arrangement, lower edge are close to inner bottom surface or are connected as a single entity with inner bottom surface or from inner bottom surface, side along be close to bucket (ware) inwall or Be connected as a single entity with bucket (ware) inwall, highly with bucket (ware) along consistent, variable amounts.
2. The method of work of lift described in claim 1 2. (or thrust) device is as follows：

   Rotated around central shaft along flabellum discharge directions, produce the inside and outside bottom surface pressure difference of housing.
