How does a helicopter fly without wings?
A helicopter flies do to rotorblades rotating. Most helicopters have two rotorblades, one to lift the helicopter off the ground, and the second, most commonly found on the tail, for stability.
What is the top part of a helicopter called?
The top part of a helicopter would most commonly be considered the rotor blades (which spin to provide lift).
Why does the total weight of the shuttle decrease in the first 20 seconds?
its weight decreases since most of that weight is fuel and is being burnt off to get lift
What is a weightlifting contest?
it's contest to see who can lift the most weight.
How is it to fly a helicopter?
Much more complicated than a fixed wing aircraft. -Military helicopter pilots in most services MUST qualify as fixed wing pilots before graduating to helicopters.

What bird can lift the highest weight?

What are Huey Helicopters used for?
The military helicopter, also known as the Huey, are used for command and control, transportation, and also assault gunships. These helicopters are the most famous military helicopters.
Why does a helicopter fly?
The rotor, shaped like an aeroplane wing, creates lift in the same way. The problem is in maintaining stability, as it will cause the body of the helicopter to rotate, too. That is why most helicopters have a tail rotor, to counter that effect and grant the pilot stability.
How does a helicopter hover in the same spot?
The lift/propulsion method used by a helicopter is capable of producing an overall thrust vector with virtually no horizontal motion. The lift method of planes (fixed wing), requires movement to produce lift. There are many possible helicopter configurations - most designs use some variation of multiple rotors placed in such a manner that rotational force is compensated for, allowing stable flight. Lift is able to be generated because the rotors (which are essentially just spinning wings) are still moving through the air, while the airframe overall stays in the same place.
What is the maximum weight man can legally lift?
Weight lifting is not illegal, but the most weight ever lifted was by Louis Cyr. He lifted 4,175lbs onto his back.
