Description
Technical field
The utility model belongs to scientific and technological activities vehicle technology field, relates in particular to a kind of for ejection type soaring aeroplane
The step wing of model.
Background technology
Ejection type soaring aeroplane model is as toy or begins to learn the teaching aid of aviation knowledge very long history.Traditional bullet
The wing for penetrating aerodone typically uses plano-convex aerofoil profile, as shown in figure 1, needing conscientious careful polishing when making, loses time；
In addition, its precision is difficult to grasp, it is necessary in advance work it out the aerofoil profile of wing, and this needs grinding tool or unified production
Line, takes energy very much.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of for ejection type soaring aeroplane model
Step wing.
The purpose of this utility model is achieved by following technical proposals.
A kind of step wing for ejection type soaring aeroplane model, including a wing, the upper surface of the wing along its
Length direction is formed with a ladder platform, and the ladder platform is located at position at chord length 45~55%, the ladder platform
Shoulder height is the 4%----6% of chord length.
In the above-mentioned technical solutions, the wing is made up of wing stage casing and 2 wing tips, and 2 wing tips are fixedly mounted with respectively
Two ends in the wing stage casing.
In the above-mentioned technical solutions, the wing tip upper counterangle is 15~25 degree.
In the above-mentioned technical solutions, the wing tip upper counterangle is 20 degree.
In the above-mentioned technical solutions, the wing stage casing is arranged on the fuselage of ejection type soaring aeroplane model by mortise and tenon mechanism
On.
In the above-mentioned technical solutions, the wing tip is packed in the two ends in the wing stage casing by way of bonding.
In the above-mentioned technical solutions, the ladder platform be located at the place of chord length 50% position.
Compared to prior art, the beneficial effects of the utility model are：Ladder platform of the present utility model makes wing formation " platform
Rank wing ", step wing makes simple, time saving and energy saving, and the processing and control of aerofoil profile are accurate, with the excellent of reduction wing weight
Point.Step wing of the present utility model, which is arranged on ejection type soaring aeroplane model, can improve the lift-drag ratio of wing, increase machine
The stalling angle of the wing.
Brief description of the drawings
Fig. 1 launches the wing of aerodone for tradition；
Fig. 2 is wing of the present utility model；

Fig. 4 is Fig. 3 partial enlarged drawing；
Fig. 5 is the schematic diagram of rotating vortex behind ladder platform；
Fig. 6 is the dimensional structure diagram that step wing of the present utility model is arranged on ejection type soaring aeroplane model.
Wherein, 1 is wing, and 1-1 is wing tip, and 1-2 is wing stage casing, and 2 be fuselage, and 3 be empennage, and 4 be ladder platform.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
As figures 2-6, wing 1 and empennage 3 are installed on fuselage 2, are formed with the front portion of fuselage for adjusting ejection
The through hole (not shown) of formula aerodone model center of gravity and the hook portion (not shown) of ejection.Wing uses three-stage
Install, wing is made up of wing stage casing 1-2 and 2 wing tip 1-1, as shown in Fig. 2 wing stage casing is horizontally mounted by mortise and tenon mechanism
On fuselage, making the connection of wing and fuselage becomes very simple and accurate, and manual connection speed is only needed to 20 seconds；2 wing tips point
The two ends in wing stage casing are not packed in by way of bonding, the wing tip upper counterangle is 20 degree, install anti-on wing tip using angle device is determined
Angle, makes two wing tip upper counterangle errors be less than 2~3 °, uniformity is strong.
As shown in figure 3, being formed with a ladder platform 4 (in wing tip and wing tip along the wing length direction in the upper surface of wing
The upper surface of section is each formed with ladder platform), ladder platform is located at position, the shoulder height of ladder platform at chord length about 50%
For the 5% of chord length.Ladder platform makes wing formation " step wing ", and step wing mainly utilizes the ladder platform in wing chord
Rotating vortex below makes the laminar flow of airfoil surface become turbulent flow, and the rotating vortex flows through machine as the ball in bearing
The air-flow velocity of wing surface does not subtract, and is difficult to separate with aerofoil surface, so, lift can be nearly all produced from the leading edge of a wing to trailing edge
Resistance is reduced, as shown in Figure 5.Lift increase, drag reduction improve the lift-drag ratio of wing, increase the stalling angle of wing.
In addition, wing of the present utility model makes simple, time saving and energy saving, and the processing and control of aerofoil profile are accurate, easy, with reduction
The advantage of wing weight.Step wing of the present utility model has the effect of traditional airfoil, is provided with flying for this step wing
Its experimental performance of machine is better than the ejection aerodone of traditional airfoil.
The ejection mode for being provided with the ejection type soaring aeroplane model of the utility model step wing is：Ejection is held using left hand
Rod, the right hand takes ejection type soaring aeroplane model (left hand is in the oblique upper of the right hand), (with ground) wide-angle (75~85 °) ejection mode
Take off.Ejection type soaring aeroplane model when taking off almost vertically upward, while rolling counterclockwise, is changed into level to peak and slides
Xiang.Be provided with the utility model step wing ejection type soaring aeroplane model take off in this way can make aircraft straight line hang down
Directly climb, the energy of elastic almost can be improved all to the height of aircraft.
Exemplary description is done to the utility model above, it should explanation, do not departed from core of the present utility model
In the case of the heart, it is any it is simple deformation, modification or other skilled in the art can not spend creative work etc.
Protection domain of the present utility model is each fallen within replacing.
