Drag cannot be eliminated because drag always acts parallel to the relative wind. We can control by purchasing or using the right airfoil on the aircraft. An airfoil with smooth surface produces more lift than one with a rough surface. A rough surface creates turbulence, which reduced lft and increases drag.
using controller to control it.. decrease weight to reduce drag
Yes, the angle of an RC helicopter can affect its speed. The tilt or pitch angle influences the lift and drag forces acting on the helicopter; a forward tilt can help achieve faster forward flight by reducing drag and increasing aerodynamic efficiency. However, excessive angles can lead to increased drag or loss of control, potentially reducing speed. Proper balance and angle adjustments are crucial for optimal performance.
A helicopter experiences drag through air resistance as it moves through the atmosphere. The main sources of drag in a helicopter are profile drag from its overall shape and skin friction from the airflow over its surface. Additionally, rotor tip vortices and induced drag generated by the rotor system contribute to overall drag.
Thrust from the helicopter's rotor blades generates lift, which enables the helicopter to overcome gravity and stay airborne. Drag acts as a resistance opposing the helicopter's forward movement, requiring additional thrust to maintain speed. Gravity affects the helicopter by constantly pulling it downward, necessitating continuous lift to counteract and remain in the air.
Drag on a helicopter can be reduced by streamlining the body and rotor blades, ensuring smooth airflow over the surfaces. Another way is to use a more powerful engine to generate more lift with less drag. Additionally, adjusting the pitch of the rotor blades to the most efficient angle helps in reducing drag.
Thrust, Drag, Lift, Weight (Gravity).
The helicopter begins to fall because gravity is pulling its weight. As the helicopter accelerates, the air passing past the helicopter creates drag, as the helicopter continues to accelerate the drag Increases until the drag becomes equal to the weight, stopping it from accelerating. Even if the helicopter did not auto rotate it would still reach a terminal speed, however the terminal speed for the non auto rotating helicopter would be a lot higher and the helicopter would take longer to reach this speed.
Birds control their Yaw by changing pitch in their main and tail wings, increasing or decreasing drag and lift from one side of their body to the other.
Hit the throttle and the helicopter will go up.
You can increase drag by increasing the surface area of an object, changing its shape to be less streamlined, or by roughening its surface. Additionally, increasing the speed of an object can also increase drag.
By increasing or decreasing the speed of the tail rotors. This unbalances the torques acting on the helicopter and causes it to spin.
