Kamov helicopters.
The development of the helicopter hasn't stopped. Nowadays there are new configurations like the NOTAR (NO Tail Rotor) and tilt rotor systems that are being further developed and refined.

Helicopters
Helicopters were first conceived by Leonardo da Vinci. Today, they perform a wide range of lifesaving roles, as well as roles in filmmaking, police work, and agriculture.
Helicopters. Aircraft deriving their lift from one or more mechanically driven rotors.
Uses of helicopters

Helicopters depend on rotors for lift, and although rotors are airfoils, they act differently than airplane wings in several important ways. These differences account for several of the major problems early designers had.
Helicopters were first developed and built as early as the first half-century of flight. Despite this it was not until 1942 that helicopters reached full scale production with 131 of Igor Sikorsky's first helicopter being produced.
RC helicopters are sophisticated and very difficult to fly.
Often considered the most difficult radio-controlled (RC) vehicles to navigate with precision, ...
Still, helicopters operate to very different parameters than fixed-wing airplanes. The overhead rotor serves as the equivalent of a wing, and maintaining rotor speed is critical. Losing rotor speed is somewhat analogous to stalling an aircraft wing.

If lift did not require power airplanes would have the same range full as they do empty, and helicopters could hover at any altitude and load. Best of all, propellers (which are rotating wings) would not require power to produce thrust.
A: Thank you for your interest in learning to fly helicopters. The ride you and your sons took while at AirVenture must really have made an impression.
Mean Aerodynamic Chord - MAC : On small airplanes and on helicopters, the center of gravity location is identified as being a specific number of inches from the datum. The center of gravity range is identified the same way.
Control system used in helicopters. Changes pitch of blades in relation to their position via a swashplate. A flybar with paddles is used to gain responsiveness. The two systems are linked with Control Levers.

LTE: Loss of Tail Rotor Effectiveness in helicopters. A low speed aerodynamic characteristic that can result in an uncommanded rapid yaw rate that does not subside of its own accord. Also known as 'unanticipated yaw' or 'loss of tail rotor authority'.
It is an extremely significant effect for helicopters. When the helicopter is in forward flight, the blade on one side has a much higher airspeed than the other.

aircraft - A machine used for flying. Airplanes, helicopters, airships and jets are all aircraft.
airflow - The motion of air molecules as they flow around an object, such as a wing.

At this period, French aviation was in a state of continuous development, with numerous flying machines being constructed and perfected. These included dirigible airships, machines with flapping wings, helicopters, and balloons with wings.
It's required equipment on commercial jetliners, corporate jets, and larger turbine-powered aircraft including helicopters, but not smaller single- or twin-engine airplanes. The FDR is typically located in the tail section of the airplane.

Helicopters can't really fly - they're just so ugly that the earth immediately repels them! Learn from the mistakes of others. You won't live long enough to make all of them yourself.
