Across the experimental model being placed in the body of hole again with through-hole, experimental model to be controlled in experimental section model during the experiment
In enclosing, the models such as support different shaping, unlike material, different size carry out the demonstration of the wind tunnel experiments such as lift, resistance；
2, the experimental section of teaching demonstration wind-tunnel of the invention, the through-hole on each side are arranged in pairs, test every time in this way
When two operating levers at least can be inserted, in this way when experiment can at least two operating levers come bolster model, with
Single operating lever bolster model is avoided, the rotation that should not occur can occur for model and interference experiment under the action of the forces of the wind；
3, the experimental section of teaching demonstration wind-tunnel of the invention is provided with the close of through-hole on the through-hole that each is opened up
Seal apparatus, to seal up through-hole, to avoid the airflow influence experimental result of through-hole is passed in and out during the experiment.Through-hole sealing dress
It is simple, easy to use, of low cost to install meter；
4, the experimental section of teaching demonstration wind-tunnel of the invention, the through-hole on each side are not only arranged in pairs, but also each
Through-hole on side is both provided with multipair, each general face is arranged 5-10 pairs, lines up two row, during the experiment can in this way
So that operating lever selects the through-hole of different location respectively on both faces, so that operating lever is formed not in experimental section with horizontal plane
Same gradient, makes model under the support of operating lever, completes different experiment tests.
5, the experimental section of teaching demonstration wind-tunnel of the invention, design is simple, and mounting hole is provided on each side, is convenient for root
Purpose constitutes the wind-tunnel of different purposes with wind-tunnel other assemblies according to the experiment, to be tested.
