The weight of the helicopter affects the terminal speed by influencing the rate at which the helicopter falls. A heavier helicopter will reach a higher terminal velocity compared to a lighter helicopter, as the force of gravity will be greater on the heavier helicopter, causing it to accelerate faster. Additionally, a heavier helicopter may require more lift to counteract its weight, which can also impact its terminal speed.

What is effect of the weight of the helicopter on the terminal speed?
When an object falls in the air, the air resistance opposing its motion increases as its speed rises, so reducing its acceleration. Eventually air resistance acting upwards equals the weight of the object acting downwards. The resultant force on the object is then zero since the two opposing forces balance. The object falls at a constant velocity, called its terminal velocity, whose value depends on the size, shape and weight of the object. This is just like Newton's laws, an object will accelerate if the forces acting upon it are unbalanced; and further, the amount of acceleration is directly proportional to the amount of net force (unbalanced force) acting upon it. Falling objects initially accelerate (gain speed) because there is no force big enough to balance the downward force of gravity. Yet as an object gains speed, it encounters an increasing amount of upward air resistance force. In fact, objects will continue to accelerate (gain speed). Or summat like that...
What is the terminal velocity of a helicopter?
Terminal velocity is generally associated with a falling object, not a powered one. Therefore I must assume that the helicopter has experienced Engine/rotor failure. Rotor failure is important because even unpowered, the rotor can be used (auto-gyro) to safely land.Let's supposed the rotors have been blown off. The falling body of the helicopter will reach a 'Terminal Velocity' of between 100 and 140 mph, depending on its Drag value. Its drag value will depend on its shape and size.
Why a helicopter during autorotation could reach terminal speed with out the pilot changing the controls?
Three forces work here. There is gravity, air resistance and the lift force made by the blades autorotation. When the air resistance and gravity forces are equal in strength, this means that the helicopter has reached its terminal velocity. It cannot fall any faster than it is. As the helicopter is using auto-rotation, the pilot does not need to change any controls because the forces will balance out themselves. The helicopter, with the aid of the still spinning blades of the helicopter, will be able to make a safe landing.
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity during this 5 second interval her acceleration?
is constantly decreasing until it reaches zero when she reaches terminal velocity. At that point, her acceleration is zero and she falls at a constant speed, experiencing air resistance equal in magnitude to her weight.
What is the solution to the helicopter physics problem?
The solution to the helicopter physics problem involves understanding the principles of lift, thrust, weight, and drag to keep the helicopter in stable flight. By adjusting the rotor blades' pitch angle and speed, the helicopter can generate enough lift to counteract its weight and stay airborne. Additionally, the helicopter's engine provides the necessary thrust to move forward or hover in place. Properly managing these forces allows the helicopter to maneuver effectively in the air.
Why a helicopter falling during auto-rotation could reach a terminal speed without the pilot changing any controls?
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.
What afectes does weight have on a helicopter?
It has a very extreme effect, if it is too heavy, it will not rise.

Will the thickness of the flap effect the rotation of the helicopter?
Rotation, no. Lift, yes. If you increase the surface area of the propeller, then you alter the lift to weight ratio.
What is the weight of a helicopter?
The weight of a helicopter can vary depending on its size. Helicopters can range in weight from a few thousands pounds to as much as ten thousand pounds.

How much down force is needed to lift a helicopter?
The same force as the weight of the helicopter and its crew and cargo.
What are the forces that have to be overcomed to launch a helicopter?
Gravity and weight.
