What is the thing on top of a helicopter called?

rotor
Overview. The helicopter rotor is powered by the engine, through the transmission, to the rotating mast. The mast is a cylindrical metal shaft that extends upward from—and is driven by—the transmission. At the top of the mast is the attachment point (colloquially called a Jesus nut) for the rotor blades called the hub.

What is the use of tail rotor in helicopter?

The tail rotor balances the forces generated from the main rotor and also allows the pilot to adjust the direction the nose is pointing when the chopper is hovering. Tail rotors are generally powered by the same driveshaft as the main rotor, allowing them to sync up.

What is helicopter blade stall?

Description. Retreating blade stall is a hazardous and damaging flight condition in helicopters and other rotary wing aircraft, where the rotor blade on the retreating side of the rotor disc in forward flight and therefore with the smaller resultant relative wind exceeds the critical angle of attack.

What is tail rotor blade?

The tail rotor system rotates airfoils, small wings called blades, that vary in pitch in order to vary the amount of thrust they produce. The tail rotor is powered by the helicopter’s main power plant, and rotates at a speed proportional to that of the main rotor.

What is the stick on the front of a helicopter?

The cyclic control, commonly called the cyclic stick or just cyclic, is similar in appearance on most helicopters to a control stick from a conventional aircraft. The cyclic stick commonly rises up from beneath the front of each pilot’s seat.

What is collective in a helicopter?

The collective pitch control (or simply “collective” or “thrust lever”) is located on the left side of the pilot’s seat and is operated with the left hand. The collective is used to make changes to the pitch angle of the main rotor blades and does this simultaneously, or collectively, as the name implies.

What is mast bumping?

Mast bumping is contact between an inner part of a main rotor blade or a rotor hub and the main rotor drive shaft (or ‘mast’). Serious mast bumping in flight usually results in the helicopter breaking up in flight, which is fatal for those on board.

What is a helicopter wing?

Unlike airplanes, helicopters feature spinning wings called blades or rotors on top. As a helicopter’s blades spin, they create a force called lift that allows the helicopter to rise into the air. A helicopter’s rotors perform the same function as an airplane’s wings.

What does Notar mean?

NOTAR (“no tail rotor”) is a helicopter system which avoids the use of a tail rotor. It was developed by McDonnell Douglas Helicopter Systems (through their acquisition of Hughes Helicopters).

What is the pole on a Russian helicopter for?

On Russian helicopters, the pole holds them up to give the illusion of flying and prevent red faced crashes. Id make a guess that its either for refuelling .OR .,….or …..

How do you identify a refuelling probe in a helicopter?

If the pole pokes out the front, it is a refuelling probe. During long search and rescue missions (CH-47 Chinook, CH-53 Stallion/Jolly Green Giant, H-60 Black Bird), they like to top off fuel tankers from KC-30 Hercules tankers. They prefer prop driven tankers that can fly slow enough for helicopters.

What are the different types of helicopters in the military?

1 AH-64 Apache. U.S. 2 MH-6 Little Bird. The Unmanned Little Bird helicopter, a smaller variant of the larger, manned A/MH-6M can be controlled by a pilot or piloted remotely.Nicknamed “the killer egg,” the Little 3 CH-53E Super Stallion.

What is the most badass helicopter in the world?
