How does air resistance affect a falling helicopter?
the same that it would affect any falling object. The higher the air resistance the thicker the air density. This will result in a higher drag coefficient and will slow the fall of the object.
How does the lift thrust drag and gravity affect a helicopter?
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.
What happens if the blades stop spinning on a helicopter when it is in the sky?
If the blades stop spinning on a helicopter while it is in the sky, the helicopter will enter a state known as autorotation. The helicopter will start to descend as the unpowered rotor blades rotate due to the upward flow of air. The pilot must carefully manage the descent and attempt to safely land the helicopter.
How does the wingspan of a falling helicopter effect the speed?
It wouldn't, the propellers are designed to propel the helicopter off of the ground, thus the word propeller, not to make the helicopter glide. The wings are too thin to hold up a helicopter and that is why they spin to gain ground as well as using kinetic energy to lift up. The propellers would eventually bend or snap if the helicopter would be to fall, the speed of the wind would break or damage the propellers.
In terms of impulse and momentum why is it important that helicopter blades deflect air downward?
The blades impart a downward impulse to the air and produce a downward change in the momentum of the air. The air at the same time exerts an upward impulse on the blades, providing lift. (Newton's third law applies to impulses as well as forces.)
How fast would a helicopter blade need to be to catch the air on fire?
Since air is not inherently flammable, there is no speed at which a helicopter blade would catch the air on fire.
What floats on the air?
helicopter
Can a helicopter work in space?
No, only specially designed rockets can go up into space. As soon as a helicopter reaches our atmosphere boundaries, it would burn up. Rockets on the other hand, have been specially made to hold such extreme temperatures. :)
How does an air ambulance helicopter differ from an ordinary helicopter?
An air ambulance helicopter is generally the same as an ordinary helicopter except for the fact that it is equipped to save lives just as a regular ambulance is equipped. Air ambulance helicopters must have the medical supplies necessary to save lives.
How does a helicopter use newtons third law?
The helicopter blades push air down. By Newton's third law, the air pushes the helicopter upward.
How can you get money for helicopter flight training?
Join the army or air force as a helicopter pilot.
What is the name of Obama's helicopter?
Marine One for helicopter and Air Force One for aero
How many feet away should you remain from a helicopter with rotors in motion?
It is not really about how many feet you are away from it. it is more about where you are standing near it. you can perfectly walk under the blades of a helicopter while in motion. just try not to jump or throw things things in the air. always enter the helicopter from the front of it, not from the back where the tail rotor or tail boom is
Why cant a helicopter work on the moon?
A helicopter requires air to generate lift from its rotors. Since the moon has no atmosphere, there is no air for the helicopter to push against and create lift. This makes it impossible for a traditional helicopter to work on the moon.
How does air resistance affect a falling helicopter?
the same that it would affect any falling object. The higher the air resistance the thicker the air density. This will result in a higher drag coefficient and will slow the fall of the object.
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.
How old do you have to ride in a helicopter?
It depends on the circumstances. A rescue helicopter, for instance, would be allowed to take anyone. The helicopters at an air show may have some restrictions due to insurance etc.
