Product information "Helicopter"
A helicopter is a vertical take-off and landing aircraft that transmits engine power to one or more nearly horizontal rotors for lift and propulsion. These work as spinning wings or aerofoils. Helicopters are thus rotary-wing aircraft and are by far the most important representatives of this large group of aircraft. "Rotorcraft" is also the appropriate translation of the word helicopter, or heli for short, which is composed of the ancient Greek ἕλιξ hélix (Gen. ἕλικος hélikos) "coil, spiral, screw" and πτερόν pterón "wing". The principle of lift in the form of a spiral was already known to the ancient Chinese, who had used it 2500 years ago in the toy "flying top". Leonardo da Vinci had made sketches of a helicopter in his "Paris Manuscripts" around 1487-1490, but it was not until the 20th century that the technical implementation of this idea succeeded.

The rotating rotor blades generate dynamic lift from the incoming air. As with the rigid wings of an aircraft, this depends, among other things, on their profile, the angle of attack and the incoming air velocity (which is not constant over the blade length), see main rotor. When a helicopter is moving forward, the incident flow velocity changes because the orbital velocity and airspeed of the forward-moving blade are added together. As the blade moves back, they subtract. Due to the aerodynamics of the rotor blades, asymmetrical forces are created on the blades moving forwards and backwards during flight, which in older models had to be absorbed by flapping and pivoting joints on the attachment, the rotor head. Newer designs do without these joints. In these newer models, the rotor head and blades are made of a composite of materials of different elasticity (elastomers as well as high-strength and lightweight metals such as titanium) that can cope with the constantly changing dynamic forces in terms of size and direction without damaging the components.
