how does a helicopter land?

Question

How does landing into wind make it eaiser to land a helicopter

Answer 1

Landing into the wind makes it easier to land for a number of reasons. When landing into the wind, it is the same as landing with forward airspeed from the helicopter's point of view. A helicopter actually produces more lift when it clears the vortex created by it's rotor. Landing into the wind allows a heavily loaded helicopter maintain translational lift longer as it slows and gets into ground effect where it can also produce more lift.

Another reason is landing attitude. Having a tailwind is just like flying backward and to land vertically with a tailwind requires nose-up attitude to keep from being pushed forward by the wind.

Third, most helicopters use a tail rotor out on a boom for anti-torque. Helicopters tend to "weather vane" because of this set-up and landing into the wind keeps it stable. Also, wind from certain directions can blow the vortices from the main rotor and tail rotor toward the tail rotor giving it turbulent air and reducing it's effectiveness. So, directional control is easier when landing into the wind as well.

Answer 2

A helicopter is an aircraft which is lifted and propelled by one or more horizontal rotors. Helicopters are classified as rotary-wing aircraft to distinguish them from conventional fixed-wing aircraft. The word helicopter is derived from the Greek words helix (spiral) and pteron (wing). The first functional helicopter was created by Jan Bahyl in year 1901 of the basis of his patent from August 18, 1895. Helicoper was 6,5 m long, weight was 50 kg and it flew 50 cm over ground. On May 5, 1905 he flew up using his petrol-engine helicopter to a height of four meters for over 1500 meters. His attempt was also recorded by the International Airship Organizement Corpis. The first fully-controllable helicopter was the Focke-Wulf Fw 61 made by Heinrich Focke in 1936, the first single-rotor helicopter - the common configuration today - was made by Igor Sikorsky in 1939.

Answer 3

HI CHRIS
it does land very slowly so least damage is caused and less jerk is given to the passengers it just decereases the angle of the rotor blades
today there are new helicopters who would land like a plane but the difference is it needs a very less runway to land

Answer 4

You decrease the angle of the rotor blades, reducing the lift that the blades produce so that the lift is just slightly less than the weight of the aircraft. This causes the helicopter to slowy descend until it hits the ground.

Answer 5

It doesn't land better or easier into the wind, unless you have some good forward airspeed, which usually isn't the case when a helo lands.

Answer 6

You have plenty of great answers to your question already and I'm NOT a pilot, so I'm going with " on it's landing gear( struts, pontoons or wheels). Thank You so much for the two points.

Answer 7

there are four forces acting on any aircraft,helicopter,etc........
ther are lift ,drag,weight,thrust
and when the lift is more than the wieght u move up and when the weight is more than lift we descend down!

Answer 8

definitely not on top of you
