When a helicopter float motionless the work done on it is zero.But why does it still consume energy?A similar question is why when we hold still a weight, we must consume energy(we feel fatigue)?
Yeah, just a bit. . .phinds said:I think the aerodynamics of it all may be a bit more complicated. . .
Both are inefficient ways to generate a static force. The energy goes into moving air and heat.fxdung said:When a helicopter float motionless the work done on it is zero.But why does it still consume energy?A similar question is why when we hold still a weight, we must consume energy(we feel fatigue)?
They don't always consume energy when floating motionless...fxdung said:When a helicopter float motionless the work done on it is zero.But why does it still consume energy?
Due to the nature of the question, the aerodynamics are unimportant and the Newton's 3rd law + definition of work (power) explanation is all that is needed.phinds said:I think the aerodynamics of it all may be a bit more complicated than that simple explanation, but you get the idea ...
Why does a helicopter float motionless but still consume gas?
Helicopters dont float, They hoverfxdung said:When a helicopter float motionless the work done on it is zero.
Yup, that description couldn't be much closer. . . as to how the real deal works .A.T. said:The energy goes into moving air and heat.
Helicopters use fuel to power their engines, which in turn rotate the blades and create lift. Without this lift, the helicopter would not be able to stay in the air and would eventually crash.
Helicopters have a complex system of rotors and control surfaces that allow them to hover in one place. By adjusting the pitch and angle of the rotors, the helicopter can counteract gravity and stay in one spot.
No, a helicopter needs to constantly consume gas to maintain its position in the air. Even when hovering, the rotors are still spinning and using fuel to maintain lift.
When a helicopter is flying, it needs to use more power to move forward and maintain lift. This requires more fuel consumption compared to when it is hovering in one spot.
The weight of a helicopter directly impacts its ability to hover. Heavier helicopters require more power and fuel to maintain lift, while lighter helicopters can hover more easily with less fuel consumption.
