Abstract
The present invention is a kind of have conventional airplane speed and car and boat economic performance, course of new aircraft of super hedgehopping.Application surface effect principle of the present invention and adopt can make full use of the special canard aerodynamic arrangement of surface effect, but can be in the surface effect district with only be with tonnage with required blade area below 1/3 and the just stabilized flight of engine power of speed of a ship or plane routine high-altitude vehicle, and can need not the airport on common ground, water surface landing.Be a kind of can be in the ocean, desert, open country, marsh, glacier be widely used in the energy-saving aircraft of new generation of the army and the people's transportation.
Description
The present invention is a kind of have conventional airplane speed and car and boat economic performance, course of new aircraft of super hedgehopping.
Asia, the supersonic flight of conventional high-altitude vehicle are very fast, but its oil consumption is very big, and need airport installation supporting, so operating costs is very high.Though helicopter can be without the airport, operating costs is very high, and freight volume is limited.The car and boat energy consumption is lower, use economy, but its running speed is too low.
Late nineteen seventies, the uncommon small-sized hydroairplane X-114 in a kind of low latitude that once designed of West Germany engineer Libiee adopts the conventional tail of single-blade peace down formula layout, take-off weight 1500kg, load 500kg, speed per hour 150km, utilizing surface effect in-flight, oil consumption is lower than its high-altitude flight.But after Libiee wished and dies in an accident in once taking a flight test, this machine development stopped.This can be regarded as a kind of surface effect machine, but the utilization of its surface effect is not very abundant, and flying speed is also lower.
The wing that the surface effect principle is meant motion is during near ground (water surface), and following gas washing stream is restricted, and the lower surface flow velocity reduces, and static pressure raises, and difference of pressure increases up and down, and wing lift increases.Along the mobile airflow drops of spanwise, tip vortex reduces thereupon simultaneously, and induced drag reduces.
The objective of the invention is the application surface effect principle, adopt the aerodynamic arrangement that can make full use of surface effect, obtain a kind of speed of a ship or plane (300-600km/h) more than middle subsonic, and energy consumption is far below the super extreme low-altitude high-speed aircraft of the energy-saving of high-altitude vehicle below the car and boat level.
The present invention proves that by tens of model plane contrast test flights the 1ift-drag ratio of surface effect district wing is more than 3 times of high-altitude at least.Surface effect district height is directly proportional with aircraft organism bottom area and its blade area, is about 1/10 of the span, and near more from the rest surface, and surface effect is strong more.
When the present invention flew in the surface effect district, blade area only needed same Airfoil, and same tonnage with below 1/3 of speed of a ship or plane high-altitude vehicle blade area, just can obtain same big lifting flight, because aerofoil can make takeoff and landing performance degenerate after too little, so optimum value elects 1/3 as.Its wing resistance also is reduced to below 1/3 of high-altitude thereupon simultaneously, so its thrust in the surface effect district when also only needing the high-altitude below 1/3, promptly in the surface effect district during only with the high-altitude required engine power just can obtain the same high-altitude speed of a ship or plane below 1/3, because the too little meeting of power makes its motor-driven accelerating ability variation, so optimum value elects 1/3 as.As seen its its usage economy is more than 3 times of high-altitude vehicle, and this is the present invention reaches car and boat energy consumption level in the flight of surface effect district main innovative approach.
As shown in drawings, underbelly of the present invention is ship shape body (1), is equipped with the landing of receipts formula to take turns, and forms special canard aerodynamic arrangement by front wing (9), rear wing (7), this layout makes the present invention can obtain maximum surface effect effect, makes the wing 1ift-drag ratio the highest.Winglet (3) hollow oil storage type floating drum (2) down both can be used as additional fuel tank, can improve this machine takeoff and landing performance waterborne again, winglet (3) can reduce airfoil vortices, the stream line pattern flight lamp (4) of its upper end helps night flying under the situation that does not increase windage, manipulation wing flap (8) and elevating rudder (6) can make full use of surface effect and improve takeoff and landing performance.
The present invention adopts advanced duct slurry fan (5) to advance, and can need not the airport on common ground or water surface landing, and shrinking can be in narrow ground, hydroplaning behind the wing.
The aerodynamic arrangement of each surface effect flight vehicle, blade area and cruising power all are certain, can only a certain height constant speed stabilized flight in the surface effect district so objectively limit it, surmount this and fly height, wing lift descends immediately, and body is returned to the former height that flies naturally; Height like flying is in this height, and wing lift obviously increases, and body is got back to the former height that flies equally.The employing reserve power of cruising can make aircraft quicken and increase flies height, operates elevating rudder again, just can climb tens to fly height to hundreds of rice.
Not only economy is splendid so the present invention flies in the surface effect district, and flight stability is good, particularly safety is much higher than in the air when water surface flying, manufacturing cost also can be far below high-altitude vehicle, after the development of maximization intercontinental model, in the ocean of taking up an area of the most of area of ball and desert, open country, marsh, glacier, all can be widely used in the army and the people's transportation, be economic energy-saving all-rounder of new generation.
