A small helicopter flies by generating lift through the rotation of its rotor blades. As the blades spin, they create a difference in air pressure above and below the blades, which allows the helicopter to rise into the air.
The main challenge in designing a small helicopter is achieving a balance between weight and power. Small helicopters have limited lifting capacity, so it is important to keep the weight of the helicopter as low as possible while still having enough power to generate lift and maintain flight.
Small helicopters maintain stability through the use of a tail rotor. The tail rotor counteracts the torque created by the main rotor blades, which helps to keep the helicopter from spinning uncontrollably. In addition, small helicopters may also use gyroscopic stabilization systems to maintain balance and stability.
The flight performance of a small helicopter can be affected by a variety of factors, including weight, weather conditions, altitude, and the skill of the pilot. Changes in any of these factors can impact the helicopter's ability to generate lift and maintain stable flight.
A small helicopter differs from a larger helicopter in several ways. Small helicopters typically have a lower weight and lifting capacity, as well as a smaller rotor diameter. They may also have a simpler design with fewer features and systems, making them easier to operate and maintain.
