How do helicopters go forward?

Helicopters move forward primarily through the tilting of their rotor blades. When the pilot adjusts the cyclic control, it changes the angle of attack of the rotor blades, causing them to generate more lift on one side than the other. This uneven lift tilts the helicopter forward, allowing it to move in the desired direction. Additionally, the rotor blades generate thrust, propelling the helicopter forward as they rotate.
