The most Advanced Helicopter design by Megaev.com!
A helicopter is an aircraft that is lifted and propelled by one or more horizontal rotors.
Helicopters are powered either by a piston engine that uses
100-octane low-leaded fuel or a turbo-shaft engine that uses Jet A fuel.
Turbo-shaft engines are a form of gas-turbine propulsion designed to produce shaft
power rather than jet thrust. They are typically used for very
short business aviation flights of less than 100 miles,
at altitudes of less than 1,000 feet.
The interior of a business helicopter typically seats 4-6 people and is configured
similar to the inside of a small car.
Helicopters are often attractive to business people because of their ability to
land at a variety of heliports and outlying airports.
Most helicopters have a single main rotor, but torque created as the engine turns
the rotor causes the body of the helicopter to turn in the opposite direction to the rotor
(by conservation of angular momentum).
To eliminate this effect, some sort of anti-torque control must be used.
The design that Igor Sikorsky settled on for his VS-300 was a smaller tail rotor.
The tail rotor pushes or pulls against the tail to counter the torque effect, and this
has become the most common configuration for helicopter design.
Some helicopters use other anti-torque controls instead of the tail rotor,
such as the duct ed fan (called Fenestron or FANTAIL) and NOTAR.
NOTAR provides anti-torque similar to the way a wing develops lift through
the use of the Coandă effect on the tail boom.
Tandem rotors are two counter-rotating rotors with one mounted behind the other.
Coaxial rotors are two counter-rotating rotors mounted one above the other with the same axis.
Inter-meshing rotors are two counter-rotating rotors mounted close to each other at a
sufficient angle to let the rotors inter mesh over the top of the aircraft without colliding.
Transverse rotors are pair of counter-rotating rotors mounted at each end of
the wings or outrigger structures.They are
found on tilt rotors and some earlier helicopters.
Quad-copters have four rotors often with
parallel axes (sometimes rotating in the same direction with tilted axes) which are commonly
used on model aircraft.
