Helicopters

Then you would have total chaos in the skies.

In 2009 more than 2100 people!

An air ambulance helicopter is generally the same as an ordinary helicopter except for the fact that it is equipped to save lives just as a regular ambulance is equipped. Air ambulance helicopters must have the medical supplies necessary to save lives.

It is one of the main controls.

Aircraft do have propellers , unless they are jets.

That's what they are good at.

The rotor and rear propeller are turned by the transmission connected to the engine

Yes, helicopters fly high when on long journeys.

It is called the rotor.

An attack helicopter is best for attacking targets and a utility helicopter is best for carrying troops and supplies.

Aircraft and helicopter sales are NEVER that simple !They almost always involve spare parts, more engines, options in weapons and comms. The latest sale of Chinooks was to Australian Army who paid just over $500 Million USD for 7 CH47 F's. -The deal also included 2 full Simulators and many spare parts.

You will have to define that in a way easier to understand.

Some large helicopters use 'drogue and hose' refuelling

The front of the main rotor is tilted down

Planes have large wings, Helicopters have rotors

The size and shape define what the rotor will lift.

Helicopters are made with sophisticated specialized engines and heavy materials which is fueled with special gas. They are also made of steel which makes it really heay.

Helicopters where used in several medical settings both Civil and Military. One of the most famous of these helicopters was the Bell H-13 Sioux most noted in the show M.A.S.H.

Coast Guard Helicopter pilots usually make anywhere from $60 to $80 dollars per hour.

To start a helicopter, the energy transformation needed involves converting chemical energy stored in the fuel into mechanical energy. This is achieved by the combustion of fuel in the engine, which creates the necessary rotational motion to start the helicopter's rotor blades.

For lifting heavy objects that would be awkward or hard for a regular crane to do.

The engine is driving a transmission which turns the rotor

It is known as "Marine One"

It's up to the manufacturer which one they like.
