Abstract
The utility model aims at providing a dish-shaped air lifting device which is simple in structure, small in occupying space, small in manufacturing and processing difficulty, low in requirement of structure strength on materials, and low in cost. Like a helicopter, the dish-shaped air lifting device is capable of slowly flying at minimum altitude; due to simple structure and small occupying space, the dish-shaped air lifting device can be used as a lifting device of a personal aircraft; due to low cost and small processing difficulty, the dish-shaped air lifting device can be applied and popularized relatively widely and is expected to reduce traffic congestion problems in personal mobility; in addition, since airflow jetted downwards by the overall dish-shaped air lifting device is ring-shaped, the dish-shaped air lifting device is good in balancing capability, so that an operation system of the overall aircraft is simplified.
Description
Technical field
A dish-shaped air lift force device, belongs to aeronautical technology field.Aim to provide the aircraft vertical takeoff and landing lift unit of a kind of miniaturization, simplification.
Background technology
Existing comparative maturity can vertical takeoff and landing aircraft air lift force device only have the screw propeller of helicopter, control more complicated.When simultaneously complicated control system has increased the weight of lift unit itself, also increased the probability of fault generation.With respect to the present invention, helicopter is had relatively high expectations to the structural strength of screw propeller, has increased material cost and difficulty of processing.Structure is compacter, can in less space, produce larger lift, and can be by regulating and controlling the equilibrium of torques of flow deflector control and regulation aircraft.Do not need special reactive torque screw propeller.
Summary of the invention
The present invention aims to provide the aircraft air lift force device of a kind of miniaturization more, simplification.A kind of dish-shaped air lift force device, by upper strata duct wall and affixed admission port thereon, be connected with conical flow guiding device affixed on the rotor discs of middle level with air inlet screw propeller, admission port prop shaft, middle level rotor discs and the fan blade, the lower floor's duct wall that are fixed in its upper surface form; Upper strata duct Bi Yu lower floor duct wall connects by regulating and controlling flow deflector, and the rotor discs center in middle level is connected with transmission shaft, and transmission shaft is connected with the aero-engine transmission shaft of the below of whole dish-shaped air lift force device by the affixed bearing in lower floor center.Upper strata duct wall is annular arrangement, and outward flange draws in and is pot cover shape downwards; Upper strata duct wall central authorities are provided with circular admission port, are the duct of air inlet screw propeller simultaneously; Air inlet screw propeller is connected with the affixed taper counterflow unit on the rotor discs of middle level by transmission shaft; On duct wall, be connected with refluence blade, be annular arrangement permutation and distribute, the flow deflector space of two adjacent annular spread.Middle level rotor discs and the fan blade that is fixed in its upper surface, blade is circular array and distributes on rotor discs; The fan blade space of adjacent two annular spread.Fan blade affixed on upper strata duct wall flow deflector and middle level rotor discs is interlaced.Lower floor's duct wall is circular, and center is provided with drive bearing.Levels duct wall connects by regulating and controlling flow deflector; Can regulate and control flow deflector and be the air nozzle that annular arrangement is distributed in annular arrangement.
Beneficial effect of the present invention: manufacture difficulty of processing low, simple to operate, have a smooth flight, whole butterfly lift unit takes up room little, cheap.

The specific embodiment
For technological means, creation characteristic, the object of reaching and the effect that the present invention is realized is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.A dish-shaped air lift force device, is comprised of three layers of upper, middle and lowers, and upper strata is that outward flange draws formula duct wall in, the planar annular duct wall 3 at middle part and the annular duct wall 11 of the downward gathering of outward flange, consists of.Duct wall circular plane duct wall 11 inner sides, upper strata are connected with admission port and air inlet screw propeller duct 7.Middle level is that rotor discs 5 is connected with engine driveshaft through lower floor's duct wall center bearing pilot bearing by the affixed transmission shaft 12 in rotor discs center, middle level.Fan blade circular array formula on middle level rotor discs 5 distributes.Rotor discs center is connected with conical flow guiding housing 9.Lower floor is circular flat duct wall 10, and center is provided with drive bearing.The outer peripheral gathering formula of upper strata duct wall ring device 6 is connected by regulating and controlling flow deflector 8 with lower floor duct wall 10.During the operation of dish air lift force device, by admission port screw shaft 1, drive admission port screw propeller 2 rotation inspiration air-flows, screw propeller edge is provided with duct wall, so the interference of air-flow in the time of can not being subject to aircraft movements.The air-flow sucking changes the flow direction by the guide functions of conical flow guiding housing 9, along duct wall to annular nozzle diffluence.In flow process, the rotor discs of rotation 5 drives the 3 pairs of air-flows actings of blade that are fixed in rotor discs upper surface, and the high velocity air again guide functions of the annular duct wall 6 by downward gathering vertically ejects downwards.The recoil producing provides lift for whole dish-shaped air lift force device.Thereby drive whole aircraft flight.
