Helicopters

Generally through the combination of Roll & Yaw.

Yaw axis is similar to how a car turns, on a Copter, the tail rotor either increase or decreases its thrust, which pushes the tail in one direction, the nose in another.

Roll axis is when the entire vehicle rolls to the left or right (one side drops, while the other rises). Say one is rolling to the right: the main rotor will cause a stronger lift on the left side of the rotary wing's arc. This will cause the left side to rise, while the right side lowers.

The control unit for doing this, called the Cyclic, will have the wings increase life by increasing the angle of attack just at the point where the effect will result in life on the left side. Due to gyroscopic progression, the actual force for this is applied 90' PRIOR to where it is needed.

Generally, aircraft like to combine both Roll & Yaw to perform what is called a Coordinated turn. Trying to simply roll, or only yaw will result in a very sloppy turn. The exception to this is when a helicopter is hovering: If they wish to point the nose in another direction, using just the YAW input is perfectly justified.

Very fast, they can reach top speed in a few minutes

Most larger hospitals have helicopter service for those who require life-flight attention. In most cases they involve severe head trauma that can not be treated at a smaller hospital. Information on air ambulance helicopters can be found at the Life Flight website.

It's top speed is about 185 mph

i believe the standard is 12 people

The Bell AH-1 Cobra had a Lycoming T-53- L13 Turboshaft of 1,100 hp

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.

A helicopter parent is a mother or father who hovers over their child like a helicopter. They are overly concerned with every aspect of their education and any problems they may have.

The Comanche helicopter is used for attacks designed for the United States Army, they are manufactured by Boeing Helicopters and Sikorsky Aircraft Corporation.

You can find information about military helicopters on the US Military website. It has a section specifically for helicopters of different varieties.

The Chinook helicopter is an American twin-engine helicopter. The helicopter is used by military forces. The Chinook helicopter is mainly used for troop transportation, artillery movement, and resupply on the battlefield.

The top speed of a Black Hawk helicopter is up to 150 knots. However, in actual operations, the realistic top speed would be 140 knots, equivalent to 161 miles per hour.

Some common nicknames for a helicopter are copter, chopper, hook, stick buddy, huey, helio, helo and whirlybird. Helicopters were used for medical evacuation but they are now the primary vehicle for air assault.

The original Huey of Vietnam war flew about 120 mph. In the Canadian Air Force we have twin jet Huey versions that will do about 145.

Igor Sikorsky created the first successful helicopter

Depends on the actual model of helicopter and what comes with it. Few helicopter deals are simple, all involve spare engines and other items.

There are many different sizes.

The Robinson 22 helicopter has a four cylinder pistol engine. The single-engine light utility helicopter was designed in 1973 and has been in production since 1979. The cost of one of these helicopters is about $270,000.

Someone can find information about helicopter sales from a number of websites such as: controller, aerotrader, global planet search, and aircraftonline.
