How much power (average) is required to keep a 1000 kg object still in air by putting a helicopter like rotating blades on it.(The entire weight of the motor to rotate the blades is included in 1000 kg).
Perhaps look at the human-powered helicopter quest to get a ballpark figure. The feat is borderline attainable, so find out the weight of the craft and pilot, and you know the power a superfit athlete can develop for a short time, so just scale this up by x5 or x10, whatever. Regard this as the lower bound for your goal.anubodh said:How much power (average) is required to keep a 1000 kg object still in air by putting a helicopter like rotating blades on it.(The entire weight of the motor to rotate the blades is included in 1000 kg).

The energy needed to stay in the air is less if you don't want to go anywhere.
The formula for calculating the power needed to keep a 1000kg object in the air is P = mgh/t, where P is power, m is mass, g is gravitational acceleration, h is height, and t is time.
The higher the object is in the air, the more power is needed to keep it there. This is because as the object gains height, it gains potential energy which must be counteracted by an equal amount of power.
No, the power needed to keep a 1000kg object in the air is not constant. It varies depending on factors such as the height of the object, air resistance, and external forces acting on the object.
Air resistance, or drag, acts in the opposite direction of the object's motion and requires additional power to overcome. The greater the air resistance, the more power is needed to keep the object in the air.
Yes, the power needed to keep an object in the air can be reduced by increasing the height of the object, reducing air resistance through streamlined design, and minimizing external forces acting on the object.
