cus it can fly
During takeoff, the helicopter blade applies lift by generating upward airflow which creates a pressure difference between the top and bottom of the blade. This pressure difference causes the blade to move upward, lifting the helicopter off the ground. The angle of attack and rotation speed of the blades also play a significant role in generating lift for takeoff.
The helicopter was designed for situations where aircraft were needed which could takeoff and land in a very small space.
Takeoff climb out speed is the speed for twin engine climb out and will get performance of best rate of climb and also it is known as (vbroc) but takeoff safety speed is the speed at which the helicopter may safely air born with one engine inoperatied and also it is known as (v2)
It can takeoff or land in where ever the position it was.... it don't need a runway...
A VTOL (Vertical Take Off and Landing) aircraft is one that can takeoff and land like a helicopter, but fly like a plane. A good example is the V-22 Osprey.
Helicopters can land and takeoff vertically and also hover in flight. Winged aircraft can not do these things.
"Helikopter," as one may guess, translates to "helicopter" in English. Helicopter, in both cases, would refer to an aircraft capable of verticle takeoff.
Helicopters need a helicopter pad to land on to ensure a safe and designated area that is clear of obstacles and hazards. Helicopter pads are designed to accommodate the specific landing and takeoff requirements of helicopters, including rotor wash and space for maneuvering. Additionally, these pads often provide a stable surface, reducing the risk of damage to the aircraft and ensuring a smoother landing and takeoff experience.
At Moscow, you have to help the robot with the colored windows to signal the helicopter to land. (see related question) You use a vertical-takeoff (VTOL) jet to travel to the various cities for the games.
An increase in ground roll.
The rotors are used for lift and thrust on a helicopter.
Interesting question. Lift is what actually allows an aircraft to leave the ground, but lift in a normal type aircraft (not a helicopter) is generated by forward movement through the air and that is produced by thrust. So, while lift is what's necessary to overcome gravity (weight), it's thrust that is needed to generate lift...so both forces are in play at takeoff.
