Abstract

A novel parallel-wing aircraft is composed of main body and parallel wings, which has a long trough shape and can swing up and down along its central line to obtain lifting force and drive force. Its advantages are high power efficiency, low cost and vertical taking off or landing.

Description

Parallel wing airplane

The present invention relates to a kind of parallel wing airplane.

This aircraft is made up of keystone configurations such as fuselage peace guide vanes, but VTOL function is applicable to the aviation industry.

Autogyro in the world today, its keystone configuration are that the fuselage and the rotatable wing are formed.Through improvement for many years, the performance of this aircraft is become better and better, and has obtained very big benefit.But this aircraft also exists many shortcomings and not enough place, mainly contains that efficient is not high, manufacture difficulty is big, cost is high, is difficult to popularize and uses.

Purpose of the present invention provides a kind of later-model VTOL function aircraft, is flat guide vane formula aircraft, and it is the dynamic efficiency height not only, and easy to manufacture, and manufacturing expense and operating costs are cheap, can be extensive use of the performance enormous function.

The object of the present invention is achieved like this, this aircraft no longer comes ascending, descending flight with the rotation wing, and uses flat guide vane instead, swing lifting flight in the space parallel with the fuselage cephalocaudal direction, improved efficient so greatly, thereby can alleviate the deadweight of driving engine and simplify manufacture craft.

Provide the simplified schematic diagram of this aircraft below

Figure one is that the internal organs of this aircraft is looked simplified schematic diagram

Figure two is that simplified schematic diagram is looked on the left side of this aircraft

Figure three is the poor flat guide vanes of type of the length of this aircraft

Further discuss the structure and the principle of this type aircraft below in conjunction with simplified schematic diagram.With reference to figure one, this is that the internal organs of this aircraft is looked simplified schematic diagram, and flat guide vane AB, CD, EF, GH are with fuselage cephalocaudal direction MN cocurrent and parallel.Figure two is that simplified schematic diagram is looked on the left side of this aircraft, and flat guide vane AB, CD, EF, GH swing up and down along the line of centers of self respectively.Figure three is flat guide vanes of this aircraft, and it is a long poor shape.Flat guide vane has the valve of subtend, i.e. the blade P of two sections of its head and the tail ₁P ₂Relatively.When flat guide vane during along the swing of self line of centers, move downward the valve closure above that section, make aircraft obtain power upwards, the valve above that section of upward movement is opened, and reduces the resistance of air.The flat guide vane of this aircraft is in the horizontal direction the time, and its cephalocaudal direction is parallel with fuselage cephalocaudal direction MN, and flat guide vane swing is along fuselage cephalocaudal direction MN, rather than vertical with it.Their pendulum angles are symmetrical up and down with level, and aircraft obtains upward force, and under their pendulum angles deflection, promptly bigger than normal to lower angle, aircraft also can obtain component forward, and aircraft is flown forward.This wing separation fuselage both sides, it can a side one wing, and a machine two wings also can side both wings, a machine four wings.One machine both wings are simple in structure, but the stressed frequency of aircraft is relatively low, one machine, four wings, the structure relative complex, but the stressed frequency of aircraft is higher relatively, stressed relative equilibrium, and this wing swings up and down by the driving engine handle and drives, the angle of the bottom generally is taken at 45 ° up and down of horizontal directions on this wing, aircraft is obtained almost be power vertically upward, improve the efficient of power greatly, and the autogyro of current pivoting leaf, it obtains raising force by the blade rotation, but in the blade rotary course air has been produced friction, wasted a part of power, when high speed rotating, waste very big, blade is not a level, but oblique, and the component of the power that it produces just vertically upward, therefore dynamic efficiency is not high, and this has just caused motor dead weight much bigger.One machine both wings, the width of wing is generally got 1 to 2 times of airframe width, length is wide 4 to 10 times of wing approximately, one machine, four wings, the width of wing is relatively littler, generally gets 0.5 to 1 times of fuselage width, and wing length can be done longerly, be 6 to 12 times of wing approximately, can make the hunting frequency of wing low like this.If require the wing hunting frequency higher, the width of wing, length can be hanged down relatively.Comprehensive other factors also is as load-carrying, flying speed, height applied environment etc.

This aircraft adopts with parallel the putting down to wing of fuselage, makes aircraft to be flown its easier acquisition power forward forward, has improved aircraft power efficient greatly, simplifies the structure of aircraft, thereby greatly reduces the deadweight and the cost of aircraft.

This aircraft is owing to the dynamic efficiency height, so the aero-engine deadweight is less, and manufacturing process is simple again, so cost is low, favourable being extensive use of.Can be widely used in aspects such as traffic, afforestation fertilising, fire-fighting, rescue, spy side, tourism, have huge economic and social benefit.
