Description

More string aerofoil profile aircrafts

Technical field

The utility model relates to aircraft technology fields, provide a kind of more string aerofoil profile aircrafts that can shorten landing distance.

Background technique

Requirement of the military aircraft due to its purposes and use environment, short take-off and landing, be the basic performance that should have it One.The requirement of carrier-borne fixed wing aircraft in this respect for aircraft carrier is just more prominent.Carrier-borne fixed-wing early warning plane is boat Mother ship carrier team is even more so under current informationization war condition necessary to off-lying sea independently implements high-intensitive air fighting.Mesh The problems such as early warning helicopter that preceding China Aviation mother ship carrier uses is short there are cruise duration, flying height is low, detection range is close, can not Meet aircraft carrier fleet high-intensitive autonomous operation demand under current informationization war condition, develops during fixed-wing early warning plane is certainly The development trend of ocean naval, state.In addition, carrier-borne fixed-wing fighter plane is because using ski-jump take-off mode without being able to maintain full oil Takeoff condition on the warship of full bullet, also makes opportunity of combat be unable to give full play its fighting capacity.Attach carrier-borne fixed-wing early warning plane for aircraft carrier, It can allow fixed-wing fighter plane with the state of the full full bullet of oil from carrier-based in off-lying sea autonomous operation, allow aircraft carrier Fleet becomes the dark blue fleet for having powerful deterrent force, should be current optimal selection.

The type that carrier-borne fixed-wing early warning plane uses in the world at present is double hair whirlpool paddle aircrafts, this is that aircraft industry is present Development level determined.

To go up aircraft carrier using the carrier-borne fixed-wing early warning planes of double hair whirlpool paddle types, must at least accomplish it is winged rise, come to Under, winged remote (hang time is long).These using catapult-assisted take-off mode aircraft carrier on accomplished substantially, but Using there are no the precedents of application on the aircraft carrier of ski-jump take-off mode.This is because turbo oar engine does not have jet engine Boosting function, additional huge thrust can not be provided improve thrust ratio taking off the period, make double hair whirlpool paddle aircrafts without Method ensures that aircraft obtains the lift that reliably takes off in the state of fully loaded.This is the carrier-borne fixed-wing early warning plane of double hair whirlpool paddle types Main in the aircraft carrier using ski-jump take-off mode uses obstacle！

There are some schemes for double hair whirlpool paddle aircraft help-flys in the prior art, for example aircraft installs rocket booster etc. additional Deng.So far, the country for all not possessed aircraft carrier adopts, feasibility be it is not high, we should look for another way.

It in jet plane before aircraft carrier, is all slided and is taken off using piston-engined propeller carrier-borne aircraft, used Be plate runway.Foremost example is to launch air raids Tokyo (TokyoRaid) in World War II to be also referred to as Du Lite air strike (Doolittle Raid), this is in World War II the Pacific War, the air strike for the first time that U.S. army implements Japanese native country. Sea state was severe at that time, and fitful wind and billow enable hull acutely wave, and made to take off more difficult.And take the lead in the Du Lite to take off only There are 142.3 meters of flight-decks available, the take-off weight of B-25B Michele bomber at this time is up to 14074 kilograms.But Du Lite is still It so successfully takes off, 20 divide 16 frame B-25B Michele bombers successfully to take off totally when 18 days 9 April of nineteen forty-two, preceding to go to bomb day This domestic military target.

In fact, the test that the U.S. and Britain did is it has been proved that not only E-2 shipboard early warning aircraft can be using sliding the mode of taking off From carrier-based, C-130F transporter, U-2R reconnaissance plane slide the mode of taking off without being transformed also use From carrier-based (not being ski-jump take-off).Only relatively reluctantly, it cannot be fully loaded with, poor reliability.In the U.S., aircraft carrier is universal It is equipped with ejector, fixed-wing carrier-borne aircraft is required according to catapult-assisted take-off under the status of manufacture, and American most has reason to be reluctant See that fixed-wing shipboard early warning aircraft becomes the standard configuration on the aircraft carrier of ski-jump take-off mode.And Chinese are it should be clear that pass through The aircraft short take-off and landing ability for improving similar E-2 type, allows fixed-wing shipboard early warning aircraft to become China's ski-jump take-off mode Standard configuration on aircraft carrier is the only selection of China.

It is the data of some aircrafts in the prior art below.

As can be seen from the above data, the thrust ratio of the B-25B during originating in World War II is not high, can run from plate It slides and takes off on road, it is small mainly to have benefited from wing load.So reducing wing load when taking off as possible is to ensure that fixed-wing flies Machine obtains enough one excellent ways of lift of taking off by self power.The wing load reduced when taking off can be by subtracting The weight of light aircraft increases wing area realization.But it at least should be at 24 tons as carrier-borne fixed-wing early warning plane take-off weight More than, so can only mainly set about from increase wing area, while trying every possible means to increase a little boosting power for aircraft, thus may Realize the target for the fieldlength (being no more than 200 meters) for greatly shortening full load condition and getting off the plane.This is for all fixed-wings Aircraft is all applicable.

Specific embodiment

The technical staff in the affiliated aerospace designs field of the utility model can correctly be managed by following examples and attached drawing Solve the utility model.Used in the utility model " it is preceding, after, it is left, it is right, on, under " isotropy word each means installation this is practical Those of novel aircraft direction.

Fig. 1 to Fig. 3 show the fixed-wing shipboard early warning aircraft of the mixed hair triplane state of a type variable string aerofoil profile, including preceding machine The wing 1, middle wing 2 be alternatively referred to as host wing, rear wing 3, winglet 4, connecting rod 5, support rod 6, sliding wheel 7, parachute 8, Spoiler 9, booster 10 and sustainer 11.Underlying preceding wing 1, rear wing 3 configuration structure be abdomen before airframe Portion and postabdomen by each installation of setting of ejection type hanger it is a pair of under outstanding wing, and on the configuration structure of the use of middle wing 2 is Outstanding wing, is fixed wing.Sustainer is installed on fixed-wing -- double hair airscrew engines 11, empennage is installed on centre Booster -- jet engine 10, such configuration are convenient for keeping the trim condition of aircraft.The face of preceding 1 upper surface of wing Product is not less than the 50% of host wing top surface area, and the area of forward and backward upper surface of the airfoil is not less than host wing top surface area 100%.Under conditions of no more than the span of former monoplane, the summation of 3 pairs of wing areas can for the span of three pairs of wings as a result, To reach 200% or more of former aircraft single machine wing area.Air inlet of the position that preceding wing 1 is installed in two airscrew engines Area, rear wing 3 are mounted on the exhaust area of two airscrew engines, are placed in the slipstream of middle wing 2.Preceding wing and rear wing Between connected by connecting rod 5, fixed support rod 6 in connecting rod 5, the upper end of support rod 6 and middle wing 2 constitute the company that can be launched Binding structure is also to be connected by ejection type hanger, and the middle wing 2 of preceding wing and rear wing and aircraft is made by support rod 6 It is connected, strengthens the stability that the wing that two pairs can launch is connect before dispensing with airframe.

Winglet 4 is arranged in preceding wing and rear wing wingtip, and the downward winglet 4 in the direction of the winglet 4 prevents Ground connection sliding wheel is also set up below the winglet 4 of the generation of induced drag, preceding wing and rear wing, the ground connection sliding wheel 7 can both support the weight of the string wing itself before take-off, in turn ensure aircraft when moving, sliding on aircraft carrier, go here and there the wing and ground Apart from constant.The airflow generated when two airscrew engine operatings brushes underlying front and back upper surface of the airfoil, makes its list The lift that plane product generates is much larger than the lift of wing in aircraft, and effect outclass the effect of wing air blowing, booster 10, more thrusts are provided for aircraft in the stage of taking off, aircraft is improved in the thrust ratio of takeoff phase, also just improves The speed of aircraft take-off run on the landing runway of sliding jump type aircraft carrier, it is ensured that aircraft can be run in the landing of sliding jump type aircraft carrier It is independently slided and is taken off with the fully loaded state of full oil on road.After taking off, shipboard early warning aircraft two propellers sustainer and help Under the collective effect that the thrust of the offer of engine 10 is provided, predetermined security area is flown to the faster speed of a ship or plane, then booster 10 It can be closed.Because fixed-wing shipboard early warning aircraft is when security area cruises, the requirement to the speed of a ship or plane is not high.Booster It is closed the consumption that can reduce fuel oil, extends the warning cruise time of fixed-wing shipboard early warning aircraft.Due to type variable string aerofoil profile Aerodynamic environment locating for three pairs of wings of mixed hair triplane is different, and the aerofoil profile of three pairs of wings, the span is also different, In, middle wing span is maximum, and preceding wing takes second place, and rear wing is minimum.Due to airscrew engine, before tubular intake region it is straight Diameter is bigger than the diameter of tubular exhaust gas region below and wind speed is relatively small, therefore, in order to adapt to this aerodynamic environment, preceding wing 1 mean aerodynamic chord is smaller than the mean aerodynamic chord of rear wing 3；The relatively rear wing of preceding wing, it is longer and narrower, it can be more Obtain lift well.In addition, fuel tank is arranged in three pairs of wings, fullyed loaded takeoff for aircraft enough lift is provided while, three A large amount of fuel oil is carried by fuel tank of the wing built in it and is gone up to the air, the hang time of aircraft is greatly increased.Appoint if executed at that time The condition of business permits, aircraft can in the state for the mixed hair triplane of string aerofoil profile for keeping type variable, in, low speed ultra-long time it is winged Row, and aircraft carrier is returned to the mixed hair triplane state of type variable string aerofoil profile.If task condition disapproves, enter stable fly in aircraft Row state, and after the fuel tank in the fuel oil input aircraft that the forward and backward string wing is carried, the underlying forward and backward string wing that can be launched is by bullet The helicopter recycling penetrating dispensing to separate with aircraft, and can nearby being cruised in the case where open parachute pulls.At this time may be used The mixed hair triplane of variant string aerofoil profile is the fully loaded mixed bill wing type state of full oil with regard to variable body.

Airscrew engine has turbo oar engine and piston engine, preferably turbo oar engine.

Fig. 4 to fig. 6 is a kind of fixed-wing shipboard early warning aircraft of mixed hair triplane state of string aerofoil profile, preceding 1 He of wing therein Wing 3 is fixedly connected all as middle wing 2 with fuselage afterwards.Wing 1 is separately fixed on the two sidewalls of forebody before a pair, Wing 3 is also separately fixed on the side wall of rear body after a pair.Because of the stability that three pairs of wings are fixedly connected with airframe Enough, there is no need to install connecting rod and support rod.

Fixed-wing shipboard early warning aircraft, if thrust ratio is not less than 0.4, period wing load of taking off is less than 220 kilograms/square metre When, it is just fully able to slide from the landing runway of sliding jump type aircraft carrier by the power of itself and take off.It and is with lower Take off from warship speed.Whirlpool paddle -6C the engine in current China has reached 5100 horsepowers, and booster can be used and be pushed away Small-sized fanjet of the power between 2-3 tons.The fixed-wing shipboard early warning aircraft for having used the mixed hair three wings type of string aerofoil profile is developed, it Take-off weight be no more than 28000 kilograms when (maximum take-off weight only has 24161 on the warship of U.S. E-2D type shipboard early warning aircraft Kilogram), thrust ratio can achieve 0.4 or more, wing area at least can achieve the 200% of former monoplane wing area with On.The wing load of aircraft is centainly less than 220 kilograms/square metre at this time.Aircraft variable body bunchiness aerofoil profile is mixed to send out triplane not only significantly The lift for improving the stage of taking off reduces required take-off distance, the also span suitably to reduce aircraft wing It creates condition, this is to aircraft parking on aircraft carrier and moves helpful.Due to the wing load of the mixed hair triplane of string aerofoil profile Small, aircraft can keep lower speed in the period of landing of taking off, and the airscrew engine used on aircraft in addition is being landed When can invert very big resistance is provided, in conjunction with the use of spoiler 9 and drag parachute on three pairs of wings, the mixed hair three wings of aerofoil profile of going here and there Aircraft just can not automatically complete landing by check cable completely on aircraft carrier.The mixed hair triplane landing distance of aerofoil profile of going here and there Short, flight stability is good, and loading capacity is big.It is not only suitable as fixed-wing shipboard early warning aircraft, is also suitable for being required to short distance Antisubmarine plane, fuel charger and transporter from (be no more than 200 meters) landing of taking off etc. aircraft carrier or it is following build possess it is straight-through It is used on the large-scale amphibious assault ship on deck.The mixed hair triplane of string aerofoil profile is since wing has three pairs, and flight resistance is with respect to single-blade Confidential big, maximum flying speed is lower.But still it is faster than helicopter speed, voyage is remote, and load-carrying is big.Due to the mixed hair of string aerofoil profile The wing load of triplane is small, and landing is relatively lower speed, can not by aircraft carrier ejector and check cable can from Main completion landing so that the peak acceleration that aircraft and pilot must endure as is small very much, this for airplane design manufacture and Pilot bring benefit itself is very big.

Fig. 7 to Fig. 9 is a kind of fixed-wing airplane carrier fighter of type variable string aerofoil profile biplane state.Only before host wing Wing 1 before being arranged on the fuselage of lower section, the configuration structure of underlying preceding wing 1 are a pair of by ejection hanger installation in aircraft preabdomen The underlying preceding wing that can be launched, the winglet 4 that the wingtip of preceding wing has direction downward prevent the generation of induced drag, preceding machine Ground connection sliding wheel 7 under winglet both supports the weight of the string wing itself before take-off, in turn ensures that aircraft is moved up in aircraft carrier When moving, sliding, the string wing and ground distance are constant.The fixed-wing airplane carrier fighter of type variable string aerofoil profile biplane state, by making The gross wing area that aircraft is increased with underlying preceding wing 1, reduces wing load, required coasting distance and liftoff speed when taking off Degree is all with reduction, and it is winged to accomplish that full oil completely bounces.And the area of underlying 1 upper surface of preceding wing is not less than aircraft main wing 50%.Because it uses high-lift airfoil, the position of installation is in the air inlet area of two engines, table on wing before making The lift that the unit area in face generates is much larger than airplane main wing.This can generate biggish new line lift in takeoff phase, The resistance of taxing for greatly reducing aircraft nose wheel enables fixed-wing airplane carrier fighter to rush to sliding jump runway at faster speed. The amount of fuel of fuel tank also has the function of adjustment takeoff phase airplane trim concurrently in preceding wing, and a large amount of fuel oil is carried and is gone up to the air, The hang time of fixed-wing airplane carrier fighter can be greatly increased.In order to balance underlying preceding wing to aircraft bring takeoff phase compared with Big new line lift can also become providing positive lift force originally in the aircraft tailplane that takeoff phase is usually to provide negative lift State, which in turns increases the total lifes in stage of taking off.When aircraft has gone up to the air, it is no longer necessary to which underlying preceding wing is given When aircraft bring lift, the spoiler on underlying preceding wing can be opened, to eliminate the extra new line that underlying preceding wing generates Lift.Enter stabilized flight condition in aircraft, and the fuel tank of the fuel oil input aircraft of fuel tank and/or other pairs in preceding wing are oily After case, underlying preceding wing can be launched by ejection and be separated with aircraft.The fixed-wing of type variable string aerofoil profile biplane state at this time Airplane carrier fighter is monoplane state with regard to variable body.If executing the condition license of task at that time, aircraft can keep type variable Go here and there aerofoil profile biplane state, in ultra-long time, low cruise flight, and with type variable string aerofoil profile biplane state return navigate It is female.

It, can also be easily with the full bullet of full oil if the invisbile plane in China has used type variable string aerofoil profile double-vane type State is slided from the landing runway on the existing aircraft carrier in China and is taken off, and with warship in block stowage, aircraft carrier or future are built It independently takes off on the large-scale amphibious assault ship for possessing straight-through deck made, after completion task under fuel charger cooperation, directly returns Marine operation sequence is added in the mode of operation in land base.Invisbile plane is independently taking off into stabilized flight condition, and will After the fuel tank and/or other auxiliary fuel tanks of the fuel oil input aircraft that fuel tank carries in preceding wing, underlying preceding wing can be with aircraft solution It is de-, it is abandoned in the case where open parachute pulls.If underlying preceding wing used in invisbile plane equally may be used using stealthing design With the stealthy state for allowing invisbile plane to keep certain, in ultra-long time, low cruise flight, and it is stealthy with type variable string aerofoil profile Biplane state returns to aircraft carrier.In the case where wartime, airfield runway was partially damaged, all fixed-wing opportunities of combat can pass through Using the mode of type variable string aerofoil profile double-vane type, coasting distance when taking off is reduced to keep lift-off fighting capacity.
