Description

A kind of short tail goes straight up to gyroplane

Technical field

The invention belongs to the gyroplane of airborne vehicle, particularly a kind of short tail goes straight up to gyroplane.

Background technology

Existing gyroplane, which can be divided into, goes straight up to gyroplane and autogiro.Go straight up to master of the gyroplane by top Rotor wing rotation produces lift, from tail undercarriage to a cross air blasting, resists the body rotation caused by main rotor moves ahead, passes through Control resists the size of power to control the direction of aircraft turn, and main rotor and tail undercarriage are all by driving engine.From rotating Wing machine, is that a kind of relative wind using during preceding fly blows top main rotor rotation to produce the rotary wing aircraft of lift, top Main rotor is not connected with engine.The propeller that the power flown before autogyro is dried backward from afterbody, tail undercarriage With engine connection.In terms of profile, go straight up to gyroplane to meet load-carrying, main rotor surfaces of revolution diameter, tail undercarriage oar Disk diameter, the length of tail, engine output, the connected mode of main rotor propeller hub, the quantity of main rotor reaches harmony Balance, just there is uncoordinated long tail.Autogyro just not long tail.Although autogyro is in terms of profile and straight The machine of liter is closely similar, but is essentially different in principle and configuration aspects, autogyro and helicopter, and wherein maximum Difference be that two kinds of aircrafts seem identical main rotor.The main rotor of helicopter is the sole power source of helicopter, is passed through Wing drop disk regulation main rotor always away from controlling the size of lift, required power when providing flight again, by inclining automatically Swash plate adjusts the size of each main rotor pitch to control the direction of flight.Going straight up to gyroplane includes individual layer main rotor, variable Away from propeller hub, main rotor vertical pivot, wing drop disk, main-gear box, engine, tail undercarriage component.Autogyro is reviewed, it Greatly rotor is that discord engine driving system is connected in flight on the crown, and the rotation of rotor is fully relied on to fly before aircraft When relative wind the effect blown with self inertia, just look like a greatly windmill, and this " windmill " is only aircraft Lift required during flight is provided.Due to autorotation, the rotor of gyroplane passes to the moment of torsion very little of fuselage, such gyroplane Also just without carrying out balance to the tail-rotor of a cross air blasting as helicopter.The propeller only dried backward, which is provided, to fly The forward power of machine.Most of autogyros can not carry out VTOL as helicopter, and must be as fixed wing aircraft Equally it can just be taken off by sliding race.But, the rotor of gyroplane can be of short duration by clutch and engine progress when taking off Connection, although this is not enough to produce enough lift to take off vertically, but the active rotation of rotor can be efficiently reduced Ground run distance when taking off.In flight course, autogyro may only flight forward, and rotor always retreats Oblique；Helicopter then can with VTOL to any direction flight even hovering, the angle of inclination of rotor also with The change of heading and change, this be also awing differentiation two kinds of aircraft most intuitive ways.When flying before autogyro Power come from the propeller of aft, it is connected with the engine of gyroplane, rotates and blow air backward so that Realize the flight forward of aircraft.Moreover, autogyro has empennage, and need to control the direction of flight by it.Most attach most importance to Want, because the main rotor of autogyro relies only on self inertia rotation in flight, so aerial meeting with engine When parking runs out of steam completely suddenly, gyroplane flying height, which declines the ascending air caused, can accelerate the rotation of rotor, so that Compensate the lift of aircraft loss, gyroplane then can in the case of no power grease it in, higher security is also The design original intention of gyroplane.In summary, gyroplane advantage is gone straight up to：It can be vertically moved up or down, hover, flown to any direction； But it has a long tail, particularly in the actual use of light helicopter, a long tail, just increases volume in tow With unsafe factor, the security of autogyro can't be performed to best.Although autogiro tail is not long, There is original security, but it does not have the maneuverability of helicopter, landing will also slide a segment distance.
