Abstract

The invention relates to a rotary short distance takeoff unit for an airplane. An initial speed is applied to the airplane prepared to take off through circumferential movement of a mechanical disc. The centripetal force is controlled so that the airplane moves from the circumferential movement to tangential movement along a certain point on the circumference according to a given demand, and the airplane skates and takes off linearly at a given initial speed effectively, therefore the airplane takes off with a short distance on a straightaway. As the speed of circumferential movement at a sub-takeoff speed can be freely set and no power bottleneck exists, the airplane in any weight can be accelerated. The airplanes in any weight can take off within a short distance through the short distance takeoff mode. The highest target of the rotary short distance takeoff unit for the airplane is that the airplane reaches the takeoff speed directly on the disc, and the airplane takes off directly on the disc by means of adjusting an air dynamical system of the airplane. Whether the target is realized or not depends on the technological level of an automatic control system.

Description

Gyropter short takeoff device

One, technical field

A kind of aviation machine is in order to airplane short takeoff.

Two, technical background

When object moved in a circle, as long as centripetal force and centnifugal force balance, object just moved in a circle around the center of circle.When centripetal force disappears, object just certain a bit on, under the centrifugal action, do straight-line motion along the circle of contact.Speed when straight-line motion begins, the linear velocity when equaling this object and moving in a circle.Use this principle, can make aircraft accelerate to a certain speed by circular movement after, and under this speed, become the straight-line motion of circular movement into carrying out along tangent line along tangent line, reach the purpose that aircraft takes off with larger initial velocity roll-out straight ahead.

Three, summary of the invention

Rotating circular disk, aircraft gate, engine installation, autonomous cruise speed system, automatic takeoff system, automatic open-close mooring ring.

1, rotating circular disk is a deep bid that can move in a circle around the center of circle of self, and area is determined with technical capacity according to actual needs.

2, the aircraft gate is the place in order to fastening aircraft, and aircraft is fixed on the rotating circular disk, does the circumference accelerated movement under the drive of disk, puts aside the kinetic energy that takes off with this.The device of simple and effective fastening aircraft must be arranged on the aircraft gate, and this device is directly connected to the success or failure of rotary short takeoff mode.This device can't provide device characteristic without before testing.But the design of this device does not have technical bottleneck, with reference to the existing one-way anchor fitting that takes off, just may be a kind of terms of settlement with the right-angle type anchor fitting that takes off.The aircraft gate can be a plurality of according to size and the airplane tail spray characteristic Design of disk, and namely once running can be accelerated for multi-aircraft.Aircraft gate even can multilayer arrange.Namely can arrange the above aircraft of two circles.

3, autonomous cruise speed system is used for the control disk and accelerates to which kind of speed and take off sequential scheduling work.The automatic takeoff function that if possible preferably possesses aircraft, namely aircraft is accelerating until leave disk along tangent line, and the driving engine acceleration of disk motion and aircraft and the action such as take off are all finished by autonomous cruise speed system.

4, automatic takeoff system is used for the autonomous cruise speed system that control aircraft work and disk work are complementary.If current techniques can be supported this automatic control behavior, this system just directly incorporates autonomous cruise speed system into.If current automatic control technology can not realize automatic takeoff, aircraft leans in takeoff phase and manually also can finish.This system is separated the purpose of discussing with autonomous cruise speed system to be to emphasize; Do not have the automatic takeoff system, this device that takes off can use in the same old way.

5, automatic open-close mooring ring is as aircraft being fixed on the aircraft gate and folding mooring gear freely.As the fixing a kind of examination property scheme of repaying of aircraft.Be constant speed degree need to decontrol aircraft the time when rotating disk reaches, the automatic open-close mooring ring, can be under aircraft huge impulse force forward, and moment opens, and makes aircraft successfully enter sliding race state.

Four, the specific embodiment

1, the mode of supposition Spin-up once can only be the airplane acceleration of taking off

Take off when preparing, it is simple effectively fixing that aircraft enters aircraft gate and the quilt of disk.Rotating disk begins to start and accelerate, and aero-engine is also in running order lower.Disk carries out the circumference accelerated movement with aircraft under the double action of self power and aero-engine power.When accelerating to namely fixed sliding running velocity and spend, the device release of fastening aircraft, aircraft loses the control of centripetal force, take the aircraft gate as the point of contact, and large initial velocity prolongs tangent line and begins roll-out straight ahead, reaches the purpose that i.e. fixed just ski-running is run, and realizes short takeoff.Here must be clear that the initial velocity when aircraft leaves disk and begins roll-out straight ahead, must be the inferior takeoff speed less than takeoff speed, otherwise aircraft is when moving in a circle, just may to make airfoil lift surpass take-off weight out of control because speed reaches takeoff speed.Certainly, rollinging takeoff at the dish circle is the highest goal of rotary short takeoff device, and this depends on the technical merit of aircraft gate and autonomous cruise speed system.Analyzing theoretically, also is possible.Suppose when rotary speed stably reaches a certain speed, by adjusting the air generation plants of aircraft, aircraft is gone up to the air in rotation, break away from arrester on the aircraft gate by lift-off, reach tangent line aloft and break away from disk, realize the purpose of taking off.

2, the mode of supposition Spin-up is once accelerated for multi-aircraft

For multi-aircraft accelerates simultaneously, stagger the time when taking off, the row of pressing of aircraft gate must avoid the phase mutual interference that the airplane tail spray causes.During acceleration, multi-aircraft is start the engine simultaneously, and the power that they produce just can make disk obtain a huge power, and this power can be used effectively.After reaching sliding running velocity degree, by autonomous cruise speed system, an airplane is let pass, and reaches the effect of efficiently taking off.Suppose that it is possible letting an airplane two seconds fly away.

3, several combinations of rotation short takeoff mode

The first, this mode of taking off once can be accelerated for several planes.After taking off, rotating disk all needs the process of a brake, installation at every turn, and this process may be bungled the chance of winning a battle.Be used alternatingly so can design two cover rotation short takeoff devices so that a cover in use, a cover oneself in installation or await orders.Two cover apparatuses can arrange energy driver, namely when a cover slows down, can utilize the energy of deceleration, directly are another set of acceleration.Namely save energy, prevented again unloaded damage apparatus.Consider the usage space problem, can with await orders, the work such as installation is placed on below the first version and carries out.Emersion first version gets final product in good time.

The second, this device that takes off can be used with elevator, can shut down at ordinary times.

The advantage of rotary short takeoff device is;

1, technology is simple, and is maintainable high.

2, energy utilization rate is high, and cost is low.

3, use on the aircraft carrier, can use simple mechanical drive, directly use Ship's Service Power Unit.

4, during the multi-aircraft standby for takeoff, the power that the set up procedure of their driving engine produces can both be used effectively.

5, initial velocity can Set arbitrarily takes off.

6, can the take off aircraft of various weight also can be realized sharing of man-machine and unmanned plane.

The rotary short square mode of taking off of an excellence of design;

One adds medium-sized early warning plane and four fighter planes when accelerating to take off simultaneously, and early warning plane skids off disk when inferior takeoff speed begins linear accelerating and take off.Because the disengaging of early warning plane, disk load diminishes suddenly, and rotating speed moment increasing makes other aircraft reach takeoff speed, and they can change the wing angle of attack simultaneously, rolling takeoff at disk simultaneously.The power of rotation begins again to drive another set of Spin-up device and starts working.
