Technical field

The utility model relates to mechanical field, relates in particular to a kind of aircraft, specifically is meant a kind of surperficial whirlpool slot type aircraft.

Background technology

At present, the flight of various aircraft such as aircraft be lean on its screw propeller rotation or turbine rotate high speed jet backward make aircraft on high in the instrument of flight.It is the plane formula structure that the macroscopic view design on wind stick, wing, fuselage, engine parts surface is, and the moving utilization ratio of existence is low, resistance big, high shortcoming consumes energy.

Traditional understanding, whirlpool masterpiece are a kind of resistance, are to hinder its flight for aircraft.

The utility model content

The technical matters that the utility model will solve is that a kind of surperficial whirlpool slot type aircraft that can effectively utilize whirlpool power is provided.

The technical solution of the utility model is; Following a kind of surperficial whirlpool slot type aircraft is provided; The surface that aircraft and air have convection current is provided with the whirlpool groove, and the cross-sectional plane of described whirlpool groove and the angle between the surface are 90 ° ± 20 °, and the angle between the axis of the length direction of described whirlpool groove and the relative aircraft flow air flow direction is 90 ° ± 20 °; Transition connects between two adjacent whirlpool grooves; Be provided with intervallum in same the whirlpool groove, the angle between the axis of the length direction of described intervallum and whirlpool groove is 90 ° ± 20 °, and the height of described intervallum is 20%～90% of a whirlpool groove extreme depth.

After adopting above scheme, the utility model has effectively utilized the theory of catching wind of flying bird feather, and flying bird was evolved through several ten million years; Wing to catch wind very capable; Through observing flying bird wing feather macro surface is the plane, and its microcosmic surface but is an a lot of vortex groove, and the whirlpool grooved profile is circular-arc; The whirlpool groove that the utility model used is crossed air from its wind current stressed variation is wherein analyzed: 1, air flows through at whirlpool groove one by one in-flight; It is the friction of air and air; Less than air and solid surface friction force; Frictional resistance reduces, air rate strengthens, and flight performance increases; 2, air and solid surface friction drag change into whirlpool on the friction of aspect windstream, air and solid surface frictional resistance disappear; 3, eddy-currents change of direction in groove, resistance becomes power.This whirlpool that just breaks traditions is just harmful theoretical, makes whirlpool become the important motivity source.

As preferably, transition is connected to arc transition, platform transition, wedge angle transition or a kind of in the wedge angle transition of the inclination of facining the wind between described adjacent two whirlpool grooves.

Preferable, transition is connected to arc transition between described two adjacent whirlpool grooves.Adopt arc transition can reduce the friction that is produced in the circulating air process to greatest extent, and can effectively reduce noise.

As preferably, the degree of depth of the described whirlpool groove of wall scroll and the setting of width have following rule, and the parts of adhering on surface are bigger, then the whirlpool groove is wide more deeply more for thicker, otherwise then the whirlpool groove is shallow more narrow more.

As preferably, two adjacent whirlpool grooves should be set to the different degree of depth and/or width to avoid producing resonance.

As preferably, the distance between two adjacent whirlpool grooves has following rule according to the width of the parts of adhering on surface, if the width of the parts of adhering on surface is wide, the distance between two then adjacent whirlpool grooves is equidistant; If the width of the parts of adhering on surface is non-wide, the distance between two then adjacent whirlpool grooves is done adaptations to scale according to the wide variety rule of the parts of adhering on surface.

As preferably, described intervallum is the crescent schistose texture, and the bottom of described intervallum posts and fixes with the intimate of whirlpool groove and is connected, and described captive joint can be riveted joint, welds or be cast into a kind of in the one.

As preferably, described intervallum is that flexible material is processed.

As preferably, described whirlpool groove is located on the covering and is applied the surface at aircraft.

As preferably; Described aircraft be a kind of circle in the air in can be on high or glide and air between have the flying instrument of convection current, described aircraft is a kind of in airliner, screw propeller machine, autogyro, space shuttle, fighter plane, aerodone, rocket, the bionical flying bird.

To sum up, whirlpool slot type aircraft friction drag when flight in the utility model surface reduces, and air and solid surface frictional resistance disappear; Resistance becomes power; The consumption of fuel saving greatly, in addition, in the whirlpool groove whirlpool can receive, damping, storage, release and buffering wind-force; The anti-turbulent interference, safety, the stationarity that have realized operation are good, and noise is low.
