Abstract
The utility model relates to a small wind tunnel testing device for students, in particular to an aerial craft model test appliance. The utility model resolves the viewing test problem of air performance of the aerial craft model. The technical proposal is that an air conduit 2 is fixed and arranged on a base plate 1, an air blowing hole 6 is arranged at the rear end of the air conduit, an air delivery conduit 7 is connected with the rear end of the air blowing hole, the air delivery conduit is connected with the air outlet of a electric blower 8, and a moving sealed cover 4 is arranged between the air conduit and the air blowing hole. The utility model testing device is mainly used for the students to view and test the performances of different aerial crafts designed by the students.
Description
One, technical field
The utility model provides a kind of wind tunnel test device, and a kind of specifically student is with little wind tunnel test device.
Two, background technology
Along with " refreshing five ", the Heaven of " Shenzhou VI ", and the propaganda of China's new fighter have emerged one space flight upsurge in China, also excited many pupils and students' innovation passion, they thirst for starting to invent various following aerospacecrafts themselves very much.So at first the dummy vehicle of being invented can be brought the wind-tunnel of doing experiment with regard to needing.
We know that the wind-tunnel in the reality is mysterious, and the ordinary people can't see, and does not also realize.Need to do yourself a maneuverable little wind-tunnel in order to solve test.For this reason, with reference to some books, the picture of newspapers and periodicals publication has finally formed technological innovation scheme of the present utility model.
Three, summary of the invention
The purpose of this utility model just provides a kind ofly to be used for student and ordinary people, easily the small-scale test wind-tunnel of control operation.
Realize that the technical solution of the utility model is such: the student is with little wind tunnel test device, forming has base plate 1, electric blower 8, concrete structure is: be set with air channel 2 on base plate 1, this rear end, air channel is provided with conical blowing mouth 6, the rear end of this blowing mouth is connecting air delivery duct 7, this air delivery duct is connecting the air outlet of electric blower 8, is provided with movable gland bonnet 4 between air channel and blowing mouth.
Imitate for obtaining dissimilar wind, between air channel and blowing mouth, can be provided with cramp bar 3, screw propeller 5 is housed thereon; Or fence parallel on the horizontal direction is set.
Be the size of controlled wind speed and air quantity, on air delivery duct 7, can be provided with valve.
The beneficial effects of the utility model are: this student controls simple with little wind tunnel test device safety easy to use; Can obtain different wind and imitate, as rotation wind, Parallel airflow etc.; The size of may command wind speed and air quantity is convenient to investigate the quality of institute's test flight device lift like this, is highly suitable for student and ordinary people and gives full play to the imagination of oneself, and following aircraft is found in the autonomous innovation invention.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Fig. 2 gland bonnet 4 of band activity not wherein.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described as follows:
Embodiment 1: the student is with little wind tunnel test device, forming has base plate 1, electric blower 8, concrete structure is: be set with air channel 2 on base plate 1, this rear end, air channel is provided with conical blowing mouth 6, the rear end of this blowing mouth is connecting air delivery duct 7, this air delivery duct is connecting the air outlet of electric blower 8, is provided with movable gland bonnet 4 between air channel and blowing mouth, and air delivery duct 7 is provided with valve.
Embodiment 2: the student is with little wind tunnel test device, forming has base plate 1, electric blower 8, concrete structure is: be set with air channel 2 on base plate 1, this rear end, air channel is provided with conical blowing mouth 6, the rear end of this blowing mouth is connecting air delivery duct 7, this air delivery duct is connecting the air outlet of electric blower 8, is provided with movable gland bonnet 4 between air channel and blowing mouth, and air delivery duct 7 is provided with valve.
For obtaining rotation wind, between air channel and blowing mouth, be provided with cramp bar 3, screw propeller 5 is housed thereon.
Embodiment 3: the student is with little wind tunnel test device, forming has base plate 1, electric blower 8, concrete structure is: be set with air channel 2 on base plate 1, this rear end, air channel is provided with conical blowing mouth 6, the rear end of this blowing mouth is connecting air delivery duct 7, this air delivery duct is connecting the air outlet of electric blower 8, is provided with movable gland bonnet 4 between air channel and blowing mouth, and air delivery duct 7 is provided with valve.
For obtaining Parallel airflow, between air channel and blowing mouth, be provided with fence parallel on the horizontal direction.
When the various embodiments described above were used, after electric blower 8 connected with the mains, fan blower was sent wind into air delivery duct 7, by blowing mouth 6, at last with wind air inlet duct 2, forms a wind-tunnel.Aircraft is positioned over the flight quality that gets final product the viewing test aircraft in the wind-tunnel.
