Abstract
The utility model discloses an airplane lift force principle demonstration device which includes a blower fan, a housing, and an airplane model. The blower fan includes a motor and an impeller. The housing is in a spiral shape. The front of the housing is provided with a spiral cover. The spiral cover is provided with a ventilating opening. The rear of the housing is provided with a speed regulating turn button and a switch. The airplane model is hung on a guide duct and is arranged on the front end of the housing, so the wind power scattering is reduced, and the wind power and the wind direction are stabilized, and consequently the experimental effect is enhanced, and the wind power unevenness and the wind direction inconsistency are solved. The students can verify the principle that an airplane wing generates the lift force along with the air flow in flying.
Description
Technical field
The utility model relates to a kind of physics teaching experiment demonstration device, relates in particular to a kind of principle that is used for demonstrating and verifying aircraft wing generation lift when atmospheric envelope flies.
Background technology
Existing like product adopts ordinary blower to make wind regime mostly; Be cut into wing with the ordinary packing plastic foam; The wind that blower fan is produced by boasting is scattering wind; The wind-force, the wind direction consistance that blow to the each point on the wing are very poor, can not verify well that aircraft wing produces the principle of lift awing.
Summary of the invention
The utility model mainly is to solve the existing in prior technology problem, produces the airplane ascensional force principle demonstration device of lift principle awing thereby develop a kind of aircraft wing of verifying well.
In order to solve above-mentioned technological deficiency, the technical scheme of the utility model is following:
A kind of airplane ascensional force principle demonstration device comprises blower fan, shell and model aircraft, and said blower fan comprises motor and impeller; Said shell is volute body; Be provided with the volute body lid in the front side of said shell, said volute body is covered with ventilating opening, and the rear side of said shell is provided with speed governing knob and switch; Said model aircraft hangs on guide duct, and this model aircraft is located at the shell front end.
As optional technical scheme, said guide duct is located at the top of said volute body, and the xsect of said guide duct is rectangle.
As optional technical scheme, said demonstration device is installed on the base plate.
As optional technical scheme; Said model aircraft comprises aircraft lifting and landing bar, aircraft and aircraft lifting and landing platform, and said aircraft lifting and landing platform adopts suspension type, is located at said aircraft before and after the said aircraft lifting and landing bar; Said aircraft wing is that the upper end is curved, and the lower end is type linearly.
The beneficial effect of the utility model is, has alleviated the wind-force scattering, has stablized wind-force, wind direction, has promoted experiment effect, has fundamentally solved the problem that wind-force is uneven, wind direction differs; Make the student can verify well that in the teaching demonstration process aircraft wing produces the principle of lift awing along with air-flow.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Embodiment
To combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
As shown in Figure 1, a kind of airplane ascensional force principle demonstration device comprises blower fan, shell and model aircraft; Said blower fan comprises motor 10 and impeller 2, and said shell is volute body 8, is provided with volute body lid 1 in the front side of said shell; Said volute body lid 1 is provided with ventilating opening, and the rear side of said shell is provided with the speed governing knob 7 and switch 6 that is installed in speed adjusting plate 5; Said model aircraft 11 hangs on guide duct, and this model aircraft 11 is located at the shell front end, and said guide duct is located at the top of said volute body; The xsect of said guide duct is rectangle, and said demonstration device is installed on base plate 3 the above model aircraft and comprises aircraft lifting and landing bar 11, aircraft and aircraft lifting and landing platform 9, and said aircraft lifting and landing platform 9 adopts suspension type; Said aircraft is located in said aircraft lifting and landing bar 11 front and back, and said aircraft wing is that the upper end is curved, and the lower end is type linearly.During operation,, open switch 6 through power lead 4 energisings, through the rotating speed of adjusting speed governing knob 7 scalable motors 10, thus the wind-force of adjusting guide duct, how Demonstrator aircraft takes off and descends.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; Can also make some improvement and retouching, these improvement and retouching also should be regarded as in the utility model protection domain.
