Convert electrical energy into mechanical energy (wind energy) by using the working principle of electric motors 
Understand the working principle of amphibious speedboat.
Know that the forces are acting on each other.

Speed boat is the ship's \"sprint champion\", the maximum speed up to 40-60 section, known as the \"Marine light cavalry\". Speed boats are classified according to the weapons they are equipped with, such as torpedo boats, missile boats and missile torpedo boats. Although the speed boat is small, but its power is not small, the effect is very big. For large and medium-sized enemy ships intruding into the coastal area, torpedo boats and missile boats can attack alone or in coordination with other surface vessels to eliminate the invading enemy ships. Speedboats can also be sent to attack enemy transport fleets and disrupt the enemy's maritime transport lines. The speed of the speedboat is fast, the boat body is small, can be concealed, can effectively attack the enemy base, parking field suddenly. In shallow channel, narrow sea area, cay area, etc., speedboat mining can be used.

The most powerful speed boat is missile boat, which inherited the advantages of torpedo boat, has a very important position in naval warfare. However, compared with the large and medium ships, it is weak in self-defense and poor in anti-storm performance, so it can only operate in the offshore area.

Modern speedboat is widely used in missile weapons, advanced miniaturized electronic equipment, high-power gas turbine and hydrofoil, air cushion technology, is moving towards the direction of missile, large, high-speed, electronic development. Speedboats will play an even bigger role in future naval battles


Scientific production:

1,Prepare the materials needed for the experiment, EVA+ measuring tube + battery box + motor + wind blade... .
2,Follow the instruction step to install.
3,The installation is completed for debugging.

Scientific development:
Speed boat is small, high speed, flexible, displacement is usually tens of tons to hundreds of tons, sailing speed of 30 to 40 knots, some up to 50 knots, endurance 500-3000 nautical miles. Boats are armed, and some boats are equipped with 20 to 76 mm guns. Larger boats may also contain mines, depth charges, etc. With the sensor system search, detection, weapons control, communication navigation, electronic warfare, and so on.
