Helicopters
A helicopter is an aircraft which is propelled and lifted in the air by one or more large horizontal rotors. Focke-Wulf Fw 61 was the first operational helicopter manufactured by Focke-Achgelis in 1936.

What fuel does a helicopter use?
Reciprocating engines: 100 octane low lead (100LL)
Turbine engines: Jet A, basically kerosene.
Helicopter is a vehicle, which flies high in the sky.Pilot flies the copter.Its capacity is very less it carries few passengers.It reaches the destination very soon so people prefer it for saving the time and for privacy
What is the difference between a chopper and a helicopter?
There is no difference, "chopper" is slang for 'helicopter'
What is the purpose of a helicopter?
It is a type of flying vehicle that helps people get around. It's advantage is being a small aircraft that can land in areas that a big aircraft can't land.
How does a Helicopter take off?
A helicopter is an aircraft that is lifted and propelled by one or more horizontal rotors, each rotor consisting of two or more rotor blades. Helicopters are classified as rotorcraft or rotary-wing aircraft to distinguish them from fixed-wing aircraft because the helicopter achieves lift with the rotor blades which rotate around a mast.
A helicopter takes off vertically by using a set of blades shaped like aerofoils to generate lift by rotating the blades at high speed and as such does not require runways
When was the helicopter invented and flown for the first time?
Henrich Focke from Germany developed the first fully operational helicopter in the world: the FW 61 with its maiden flight in 1936.
What are some of the dangers involved with helicopters?
Malfunction causing the controls to fail leading to a horrific crash(RARE). Storms causing you to lose control of the Helicopter(Unlikely with experienced pilot). and more. but if you are in a helicopter with an experienced pilot and a tested safe helicopter, you will be fine, its just a fear for most people. In winter snow conditions, there is the danger of "white out". When the helicopter approaches for landing, the rotor down wash can kick up the snow and suddenly the pilot finds himself blinded by the whirling snow and he can't see. Tail rotor strikes. The tail rotor is spinning very fast and is large. Pilots sometimes don't realize where the tail rotor is and they swing the helicopter around and hit something with it. Also passengers or ground crew have been known to walk into the blade.(rare with experienced pilot)
When were Orangutans put on the Endangered Species list?
cause they got tired of people hunting for them so the star to kill people they got tired of people killing them so they started to kill people
The name Huey is applied to the Bell military helicopter UH-1 Iroquois and its variants, including the AH-1 Cobra, UH-1Y Venom, and AH-1Z Viper. The AH designation indicates attackhelicopters, and the U designation means utility. The name can also be applied to the civilian variants, the Bell 200-series (204 up).
The original "Huey" was the UH-1E used extensively by the Marines in the Vietnam War.

Who created the first helicopter?
Igor Sikorsky .
The first helicopter was the Focke-Wulf FW 61 in 1936. Heinrich Focke and Gerd Achgelis were the creators. Full scale design and production did not occur, however, until Igor Sikorsky got involved in 1942.
Answer
Helicopters are made of aluminum alloy, steel, composite material and titanium alloy. Modern helicopters have a lot of its fuselage or blades made of composite materials.
Blades
Helicopter blades can be made out of wood, aluminum or composite. The very first helicopter blades were cut from wood laminates, just like early airplane propellors. Then they made them out of Aluminum. The front Spar of the blade is an aluminum extrusion that is shaped like a "D". The wing behind the spar is made of honey-comb aluminum which is thin as foil and aligned vertically. This is covered with a aluminum skin and a small wedge of aluminum is attached at the trailing edge.
Composite rotor blades are similar construction. The Spar is made by wrapping composite fibers around a form for the length of the blade. Then a composite honey-comb material is attached to it and covered with composite fabric material for the skin of the blade. This is baked in an oven. Usually a steel leading-edge abrasion strip is attached that acts to protect it from damage by hail and rain.
What are the raw materials used in the automotive industry?
Steel which is really important for them and oil i think?
How do helicopters change direction?
The rotor blades when spinning creates what is called the rotor disk, the disk is tilted in the direction that the pilot wishes to go.
Why do helicopters need tail rotors?
When helicopters main rotors are turning, it is the natural reaction of the fuselage of the helicopter to spin the other way, this is known as torque, a tail rotor spinning counteracts this force by pushing the other way, The rotor pedals change the pitch of the blades on the tail rotor, if the pilot wants to spin left, he compresses the left anti-torque (yaw) pedal, and the blades will alter their pitch to offer less resistance, making the fuselage spin left, if he wants to turn right, then the pilot will press the right pedal,this will make the blades on the tail rotor change pitch to make even more resistance...this overpowers the torque force and makes the helicopter turn right. hope this helps :)
Parking at my office sucks. I started commuting via helicopter. Now I just tie it to a tree and leave it running...
How much does a helicopter propeller cost?
The "propeller" of a helicoper is actually a set of rotor blades. They cost anywhere from a few thousand to a few million dollars each.
Why doesnt a egg break when you squeeze it?
The arch is one of the strongest forms in architecture. The shell is in a design that maximizes strength while minimizing material, a good idea when it requires something sit on it to hatch it out!
Some Helicopters have Oelo type struts. Sikorsky CH-53's and blackhawks, Boeing CH-47 Chinook and CH-46 Phrogs. Struts usually refer to a part of the landing gear and it purpose is to act like your shock absorber on your car to dampen out rough terrain while taxiing or during take off and landing (even thought all helicopters can take off and land vertically the heavier models that can carry more weight will try to use running takeoffs or landings for safety
Why was the helicopter invented?
One of aviation's greatest designers, Russian born Igor Sikorsky began work on helicopters as early as 1910. By 1940, Igor Sikorsky's successful VS-300 had become the model for all modern single-rotor helicopters. He also designed and built the first military helicopter, XR-4, which he delivered to Colonel Franklin Gregory of the U.S. Army.
Igor Sikorsky's helicopters had the control to fly safely forwards and backwards, up and down, and sideways. In 1958, Igor Sikorsky's rotorcraft company made the world's first helicopter that had a boat hull and could land and takeoff from water. It could also float on the water.

I cant tell you what all the buttons do but I can say the basics.
When you are seated in the right side of the helicopter in the pilot seat, you will find both your arms and legs resting on the controls.
In your left hand you will be holding the collective pitch, this increases or decreases the engine speed. This gives you the ability to control the altitude of the craft. In the right hand you have the cyclic pitch, this tilts the main rotor so the helicopter can move left right backwards and fowards. As the craft is tilted forward the chopper will start to pick up speed. Your feet rest on the rotationairy pedals. These control the tail rotor, enabling you to rotate the helicopter whilst hovering. The rotationairy pedals are usually used in combination with the cyclic and collective pitch to make tight turns at low altitudes.
For a pilot to succsessfully control the craft and get the maximum capabilities out of it. He must be at full alert at all times and use all the controls to operate the craft.
Radar awareness is also very important for the pilots safety, especially at night.
The radar hub is usually located under the nose. Some military model helicopters however, such as the AH-64 apache longbow, have the radar hub sitting ontop of the main rotor shaft.
