Anxious slave jet flow seam 20 sprays flat fluid stream airfoil, after rectified 24 rectification of knife, increases advance and climbing power.
As shown in Figure 3-4, it is equipped with jet pipe 19 in the front end upper surface of the span 2 and tailplane 3, on jet pipe 19
Equipped with jet flow seam 20, the airflow direction that goes out of jet flow seam 20 is directed at the gentle face of arc above each wing.Spray in the span 2 and empennage 3
Flow tube 19 is connected by pipe fitting 21 with opening telescopic cover 5, and pipe fitting 21 is opened up in spademan at 2 its nearly fuselage 1, and pipe fitting 21 is
Three-way pipe, main siphunculus receive telescopic cover 22, and the operation principle of the reception telescopic cover 22 is identical with opening telescopic cover 5, and reception is stretched
The gas outlet of the air inlet connection opening telescopic cover 5 of contracting cover 22；Its second siphunculus is larger, connects jet pipe 19；Its third siphunculus
It is smaller, pass through fixed jet pipe 19 on the logical empennage 3 of the connection of connecting pipeline 23 of 1 inner wall belt controlled throttle of fuselage, the empennage 3
Upper fixed 19 structural principle of jet pipe is identical with the structural principle of the jet pipe 19 in the span 2.The span 2 and empennage 3 using into
Swept-back is preferable, and jet pipe 19 and former 4 jet flow line of jet engine is allow to form mitre and on-right angle, can reduce meaningless work(
Consumption.The overcurrent time on streamiline surface is grown with wide short wing for lift foot, increases pressure difference area and gratuitously improves lift.
As shown in Fig. 1,3,4, the upper surface of the span 2 and empennage 3 is all uniformly distributed fixed rectification knife 24, each rectification knife 24
It is parallel with the axis of fuselage 1 during vertical view.Another each wing does as usual and has traditional flap and control system and the tail vane on the perpendicular wing of empennage 3
And control system.The Novel speed-reducing plate after moving behind slightly improved flap axle center is expressed in Fig. 4, when it is lower tilts, on
Side can block air-flow shown in arrow and folding can be descended to tilt, this, which can cause aerofoil to generate negative pressure, can generate lift but not generate advance
Thrust, while the air-flow for being folded to lower section arrow generates work rising counter-force again, works along both lines, its positive good utilisation airplane inertial is to slow down
Plate is to air damping reduction of speed but does not lose lift and is allowed to suspend to offset aircraft gravity, and such aircraft, which is in, to land at a slow speed, can be complete
It is fallen into extremely low into prompt drop, meets the landing of dash road.When far place starts this operation, then runway can be shorter.It also can be used during rising
This maneuver, aircraft is substantially motionless or few dynamic, and the Novel speed-reducing plate then aircraft that gradually returns to normal rises with before when being intended to or have gone up
Into.
As shown in fig. 7,3 lower part of empennage of jet flow aircraft of the present invention is equipped with automatic control hook mechanism 26, automatic control hook machine
Structure 26 is made of movable hook 27, third hydraulic cylinder 28 and scalable rope hook 29, and movable hook 27 is fixed in or beyond tail storehouse, the
Three hydraulic cylinders 28 are fixed in tail storehouse, and piston crown is hinged the waist of movable hook 27, pass through 28 piston of third hydraulic cylinder
Movement, movable hook 27, which can be hooked or be put down, is placed on place the rear fixed scalable rope hook 29 that stretches.
Jet pipe 19 and each wing and rectification knife 24, when 19 jet flow of jet pipe, when fluid is sprayed from each jet flow seam 20,
Because at a high speed, which can generate the wall attachment effect of jet current principle, i.e. the flat fluid meeting by flat seam out in each wing upper surface
It is close to the attachment flowing of wing table without detaching, therefore is close to wing table differential of the arc face not from simultaneously because the given specified stream of rectification knife 24
Dynamic direction, the stream spray the parallel current after rectification in 1 axis of fuselage backward, even if this is first because each wing upper table is flying
The high flow rate fluid for being covered with all-wing upper table has just been obtained when machine is static, and each lower aerofoil is hydrostatic(al) air, and hydrostatic(al) is big
Air pressure is substantially greater than fluid air pressure forever, it is more than wing following table flow velocity with wing upper table flow velocity during conventional flight and generates speed difference and pressure
Poor different, the former with the latter has tens times to hundred times lift ratio, and pressure difference is very big, and then aircraft has just been obtained in static state
Strong lift gesture, when the fluid flows out backward through aerofoil, more than by above-mentioned flap maneuver, before which forms aircraft again
Into the reaction force of power, when jet sprays at full speed, original be intended to rise or begun to rise and it is former be intended into or begin into situation become fast
Speed rise with into, then without how many runway i.e. rise；Jet engine can be dropped to bottom at this time and be detached from spademan progress jet,
Work flight as common jet plane；If jet engine stop place for top in situ as usual can fly but rise into than
Greatly, can rapid increase, while the horizontal tail air-flow of empennage 3 is reduced with throttle valve, can make high-angle-of-attack flight without stall；Work as stop
When jet receives telescopic cover half, rise into than reducing；When side, the strong opposite side of wing jet flow is weak, can turn round and fly or be equipped with
Tail vane, if more than it is each it is motor-driven be equipped with the operation of suitable unilateral or bilateral flap again or containing linkage, can efficient maneuvering flight.
When aircraft landing, first beginning position will be moved on jet engine, subtract jet and fly slowly, open simultaneously the deceleration upwarped
Plate tilts proper angle, and a part allows flight from the outflow of top airfoil gaseous blast as forward thrust, but the stream is because of brake drag effect
Its jet flow is prevented to fly again, and aerofoil stream but with lift, therefore occur aircraft by based on uplift force and what forward force was reduced
Phenomenon, thus it can descending at slow speed, equally shorten runway, and drag parachute open then stroke it is also short.Or by it is above-mentioned
It states maneuver flap to tilt down, shorter runway effect landing will be obtained.If making high-angle-of-attack flight with the maneuver, aerofoil flies gas
Stream is hampered by the head that flap is slightly pulled, and the air-flow being folded down by it increases spray downwards and then increases upward kinetic energy, can generate
Rise the effect that radius reduces, mobility increase is very big, because it is torrent, more than usual air velocity to the work of flap
With.
If making runway shorter or zero runway, hooked when taking off with automatic control hook mechanism 26, jet is allowed to put hook, aircraft up to peak
It will take off in the case of highest thrust and lift, then runway will be shorter or be zero.Automatic control hook mechanism 26 is by movable hook 27, third
Hydraulic cylinder 28, scalable rope hook 29 form.Movable hook 27 is fixed on tail lower hinge, and gib head can expose or the machine of retraction fluting
In tail, waist has the piston crown that hole is hinged third hydraulic cylinder 28, and third hydraulic cylinder 28 is fixed on the corresponding position tail of tail
Portion is articulated in deck store, makes the cylinder body that can shake, and scalable rope hook 29 can be located in ground with Retractable before and after aircraft gate.
It is firmly scalable with hand hook in the case that cause movable hook 27 has been put down after scalable rope hook 29, which is hooked, to be extended by third hydraulic cylinder 28
Rope hook 29 is at 27 mouth of hook of movable hook and tightens scalable rope hook 29 and tenses positioning, and when engine start and up to Best Thrust when dashes forward
So movable hook 27 is retracted unhook, then aircraft immediately with maximum raise power into liter, then runway can be shorter, and it is female to be especially suitable for aviation
Warship carrier-borne aircraft rises soon, and land used saves big portion, can make warship overloading aircraft and slightly save fuel oil, mobility is superior.Also may be used during aircraft landing
The pintle that aircraft puts down is mixed with traditional arrester wires faster to stop aircraft.It can make former aircraft carrier cancel electromagnetic launch, and increase
One times of number of aircraft or more, while air maneuver is more preferably.Large area runway can be saved for airport or home airdrome can be used
The number of aircraft doubled or more.For wartime, common level land or highway can be used as airport to lift road, have strategy meaning
Justice.Enormous expenditure is saved above.
High temperature alloy such as titanium conjunction can be used in each mechanism parts of the jet engine of more than the present embodiment, all high temperature that relates to
Gold, nickel base superalloy, ceramic based high-temperature alloy, titanium rhenium alloys, rhenium alloys etc., are selected depending on feelings.
The course of work of jet flow aircraft of the present invention is as follows：
Before taking off, two jet engines 4 are in highest point, and opening telescopic cover 5, which is in, shrinks alignment reception telescopic cover
22, it fires an engine, is rectified after spraying the rectified cover 18 of air-flow, form bigger blowing force by shrinking the telescopic cover that is open through appropriate
5 enter appropriate appropriate opening receive telescopic cover 22 again the second siphunculus through pipe fitting 21 enter in the jet pipe 19 on spademan 2 and
Enter in the jet pipe 19 on empennage 3 through third siphunculus and connecting pipeline 23, the fluid is full of in each jet pipe 9 and from jet flow
It stitches 20 full sealings to spray in flat, which sprays to each aerofoil with wall attachment effect tightly attached aerofoil, and top airfoil corresponds to bottom wing
Face, lower aerofoil is there are one air static pressure, and high-velocity fluid is flowed through as a very big negative pressure top airfoil, then up and down it is wing into
Very High Pressure Difference, uptrend in generation, while because the fluid is flowed out along wing tip, and blowing force acts on aircraft into advance gesture after generating,
Maximum lift and forward force are just obtained when 4 full speed jet of jet engine, sliding running how many road are just liftoff rises.Or it uses
Above-mentioned Novel speed-reducing plate method makes generation suspension gesture, then there are few runways to rise.
According to automatic control hook mechanism 26, then the runway is shorter, because of it when full speed jet just puts hook, passes through third hydraulic cylinder 28
Pull-up movable hook 27 flexible rope hook 29 is made to bump against tail body lower part and break off relations, aircraft has obtained peak acceleration before unhook,
Therefore break off relations after scalable rope hook 29 is by tail lower tail lug hook, it takes off rapidly.In normal flight, jet engine 4 can
Drop to bottom, carry out conventional principle flight, receive telescopic cover 22 at this time and collapse opening to minimum according to aforementioned structure, to meet air
Principle of dynamics, first opened when making a return voyage jet opening telescopic cover 22, even if then rise jet engine 4 to highest order jet opening stretch
5 alignment jets of contracting cover receive telescopic covers 22, open each airfoil camber flap, make aerofoil stream by butting part or whole, before making
It reduces or disappears into power, because top airfoil fluid still has, upper and lower pressure difference exists, and lift remains, and forward force or only relies on aircraft and is used to
Property then can, because the horizontal tail of spademan 2 and empennage 3 still has lift, thus will not stall it is out of control, treat to drop pass before ground soon or gradually close engine
4, opened by flap or drag parachute, then can dash road or the landing of shorter runway then may be used.Also it is not excluded for separately setting biography with traditional tail
System stops hook and hooks arrester wires shutdown.Make outside when Fig. 4 angles position band tilts according to Novel speed-reducing plate, which can stop
Sprayed after aerofoil jet flow, it both generated negative pressure in aerofoil makes generation lift, while the stream and can fold down it is rectangular into rising counter-force gesture,
It works along both lines, then can land under very slow state of flight, form dash road, this operation is just carried out if far, at flying speed
In pole slow state, then landing runway only counts meter Yi Ke.
During as maneuvering flight, according to the solution of the present invention, turn, turn left Ru left and right, left wing subtracts Jet Stream, left wing
Climbing power reduce, while tail vane turn left or add left flap upwarp or it is sagging (regard descending manner turn round or ascending manner turn and
It is fixed), aircraft "Left"-deviationist is then turned left, and is similarly turned right, and right flank subtracts more than Jet Stream similarly symmetry operation, cancels：Or allow jet engine
4 drop to bottom is upwarped opposite side with certain side flap and is had a downwarp with conventional airplane turn；When diving instantly, according to the scheme of invention,
2 bilateral of spademan upwarps proper angle front reduction gear plate, and damping makes forepart thrust reduce sinking, but 3 horizontal tail automatic control throttle valve of empennage
It opens to most ambassador's jet flow maximum, empennage 3 has upwarped relatively or, just formation underriding sagging plus 3 flap of empennage.Or using jet
Engine 4 drops to bottom, dives in a conventional manner；If High Angle of Attack to be obtained rapidly rises, according to the solution of the present invention or empennage
3 flaps upwarp or close empennage jet with throttle valve, and 3 flap of empennage upwarps, and rear body is made to sink, the span 2 is slowed down
Plate has a downwarp, in addition the span 2 has torrent pressure difference that forebody is made to increase above, then can generate High Angle of Attack and rapidly rise.Or using jet
Engine 4 drops to bottom, and it is motor-driven that this is carried out in a manner of conventional flight.But the present invention is because aerofoil has always compared with lift, same to learn
It practises driving time and is not easy to stall, but custom answers slight changes.
For safety, it is all with former Traditional control, then without warning or sound in cabin, otherwise with warning i.e. by second set of behaviour
Make；Or linked completely with computer with second set, tradition is a set of to use origin operation, but only pull second set completely with second set
Switch, then all custom operations are constant, but of the invention with second set at this time, and combined operation is previously set with program, is wrapped
All hydraulic cylinder is included, autonomous linkage is formed, to meet traditional operation.
Specific embodiments of the present invention are described in detail above, but it is only used as example, the present invention is not intended to limit
In particular embodiments described above.To those skilled in the art, any equivalent modifications to the invention and replacement
