1. The flying principle of a helicopter is similar to which of the following toys?
bamboo dragonfly
top
2.Correct answer: bamboo dragonfly
3. Answer analysis:
The cross-section of a helicopter blade is thick at the top and flat at the bottom. When the blade rotates and cuts through the air, under the action of Bernoulli's principle, the air flow speed is fast and the pressure is small on the upper surface of the blade, while the flow speed is slow and the pressure is strong on the lower surface of the blade. The resulting pressure difference causes the aircraft to gradually rise.
