Product Description
Principle of Airplane Lift Demonstrator (Teaching Instrument)
Product Introduction
This demonstration of airplane lifting principe is composed of fan, aircraft model, transparent cover, slide bar, slide bar pressing plate, wood base, etc. Except for the aircraft model and slide bar pressing plate can be removed, other parts of this instrument are fixed.
The wing section of the aircraft model is round at the front end, sharp at the rear end, curved at the top, flat at the bottom, and asymmetrical at the top and bottom. In this way, when the air flows to the aircraft model (equivalent to the aircraft sliding forward), according to Bernoulli's theorem, when the air flows through the upper wing surface, the air flow will be squeezed faster, and the pressure will be reduced. When the air flows through the lower wing surface, the air flow will be affected by resistance, and the velocity will be slow, and the pressure will be large, This pressure difference forms an upward lift. When the lift is greater than the weight of the aircraft, the aircraft will fly.

Instructions
1. Before the instrument is powered on and used, ensure that all parts of the instrument are in the state shown in the schematic diagram (the aircraft model should be belly down and pass through the two sliding bars on the flat bedplate).
2. After confirming that there are no other abnormalities, close the power switch, and the internal motor runs. At this time, observe through the transparent cover, and the aircraft model will slowly rise... After the observation, disconnect the power switch
3. The height of the aircraft model can be controlled by the air volume adjustment knob.
- Take the slide bar pressing plate, take out the slide bar of the aircraft model upward, turn the model belly up, put the model slide bar forward, cover the slide bar pressing plate, and close the power switch of the instrument again. After observation, it can be found that when the model belly is upward, the model will no longer rise with the wind force.
Product feature and application
This instrument is used to demonstrate and verify the principle of wing lift when an aircraft flies in the atmosphere. The utility model has the advantages of beautiful appearance, simple operation, good verification and strong interest.
Maintenance and precautions
The instrument shall be placed in a cool and dry place after use to avoid contact with corrosive gas or liquid.
The instrument shall not be under heavy pressure or dropped to avoid damage.
