Are helicopters powered by jet engine?
some are, but like 99% are propelled by propellors on the top Actually all helicopters use a main rotor and a tail rotor for lift and stability. Most late model helicopters utilize a jet engine and transmission power train. Not unlike a torbo prop arrangement.
How does the function of the propeller differ in airplanes as opposed to helicopters?
Fixed wing aircraft use propellers for thrust only. A helicopter uses it's rotors for lift, thrust, and directional control. The tail rotor uses blade pitch to control yaw.
What do helicopters do to the environment?
Answer Nothing more than any other type of airplane or car. Most helicopters are powered by jet engines that use a gearbox to power the rotor blades. The turbine jet engines are relatively evironmentally friendly compared to other internal combustion engines.
Oyster blade on whal clipper?
You can use any blade on any clipper, so long as you use the correct size.
Are there any RC helicopters that use button cell batteries?
yes
What kind of gas does helicopter use?
Many small ones have gasoline engines. Most large and military helicopters have jet turbines, connected to a transmission that drives the rotor.
What is a swashplate?
A swashplate is a type of mechanism which allows a rotating motion to be transferred into a reciprocating motion. It is used in some types of engines and hydraulic equipment, but the most common use is on the main rotor and tail rotors of helicopters. On a helicopter the swashplate is a part of the helicopter rotor which allows the rotor blades to be manipulated to control the aircraft. As each rotor blade swings around the center of the hub, the swashplate will increase its angle of attack on one sideof the arc, decrease it on another and so on in order to allow the helicopter to be rolled or pitched according to the pilots commands.
How can helicopters fly?
Leonardo da Vinci had drawings of a helicopter but it took Igor Sikorsky to build one that worked. They use rotor blades to create lift.http://www.explainthatstuff.com/helicopter.html
Why don't helicopters spin in circles?
The back rotor of the helicopter counters the force applied to the body of the helicopter by the main rotor by applying thrust in the same direction as the main rotor. The force from the main rotor is applied in the opposite direction the main rotor is spinning. So say the force the main rotor was exerting on the body of the helicopter was causing the tail to move left then the back rotor would be designed to apply an equal force pushing the tail right to keep it from spinning. If the back rotor of a helicopter malfunctioned it would begin to spin.
Do they use helicopters in Wisconsin?
Yes, they have many helicopters in Wisconsin.
How does a helicopter rise into the air?
Simple answer: By blowing air at the ground. Long answer: Air moving in the right way can have immense force behind it. Hurricanes can flatten trees, tornadoes can pick up cows and jet aircraft can use a directed jet of air to propel itself. The Rotor blades of a helicopters are like a massive, high powered fan that blows air downwards. Each rotor blade has an airfoil profile (similar shape to the cross section of an airplanes wing), so as the rotor blade turns it generates lift, just like an airplanes wing. The when the blades turn fast enough the lift forces will be greater than the forces of gravity. The pilot can control this by altering the angle of the blades. As the pilot increases the angle of the blades, more lift will be generated. In practice all helicopters do not have much variation in rotor speed during flight, and the rotor speeds are a lot slower than most people realise. But there's a problem known as Torque Reaction. If you just have a single main rotor, then as the helicopters blades starts to get to a state where lift from the blades equal the forces of gravity, the helicopter will start to spin on the spot. (A visual thing to see this in action is watch the film Black Hawk Down, when the helicopter gets shot and loses its tail rotor). To balance the forces induced by torque reaction, most helicopters have a tail rotor at the end of the tail boom. The tail rotor blades have a variable angle controlled by the pilot, like the main rotors. Adjusting the angle of blades will balance the forces of torque reaction. Altering this angle in a hover will allow the helicopter to turn on the spot.
Why do people use helicopters when its emergency?
cause helicopters are really fast
