Description of the model.

The model is constructed as a box in the middle is an up and down mechanism where the pilot is placed. The drowning is a cardboard figure with an eye to wire on his helmet. The figure is surrounded by the sea and of course the part immediately revolves around him around to suggest the influence of the helicopter rotor on the water. Above the water moves a helicopter Sikorsky S-58. This type made its first flight in 1954. It is primarily used as military transport helicopter. He is also widely used in Vietnam. The helicopter can move in all directions. Above the door is a pulley system mounted that the drowning will be saved.

The movements of the helicopter and operating the hoist is via push buttons which are in front of the model.

The fairly strong winds is generated by two propellers.

The operation of the model:

When the program starts an initialization is first performed. The helicopter is placed in the position and the hoist is up to the top position, top position is determined by a reed switch with magnet the hook block. Then the tail rotor and main rotor rotation, the water in motion and the wind stirred.

Now the helicopter with the buttons in the best position and put the hook lowered. It should therefore be attempted to hook into the eyelet on the helmet to bring and then the swimmer to hoist. And that’s difficult because the victim is unconscious and can not cooperate, but he goes through the swell irregularly and even goes up and down several times submerged. In addition, the winds from different directions so that the hook is far from stable.

After several attempts, you can develop a strategy which eventually the drowning man will succeed to win. There are several difficulty levels possible by the prevailing wind and the velocity of the upward and downward movement of the swimmer.

See the movie especially for the operation of a thing.
