The source of lift force from the rotor (Rotation of two objects 'blade' creates a lifting force) blades allows the helicopter to stay in one area for extended periods of time. Each rotor blade, whether it is 2 or 7, has the ability to change pitch. This means the blade can rotate so that the nose or leading edge can tilt down or up. If it pitches up, the lift of the blade increases. Collective Controls As the blades rotate it produces lift. The pilot inputs controls that increases the pitch on all the blades at once. All the blades pitch up and produce more lift, so the helicopter rises. Cyclic Controls The pitch of the blades can also be controlled so that the blade pitches UP when it is on one side of the helicopter and pitches DOWN when it is on the other side. As the advancing blade is moving from rear to front, it decreases it Lift. Then as the blade moves to other side, it increases its Lift and pushes the helo through the air. In a simply explanation, this is what causes the helicopter to fly forward. Think of it like someone paddling a canoe. On many helicopters, the input is accomplished through the controls of the Swashplate. Custermen - Worked 11 years at Bell Helicopter.
What else can I help you with?
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.)
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.
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.
Why would a helicopter hover in the same position?
A helicopter hovers in the same position by using its rotor blades to generate lift and counteract gravity. This allows the helicopter to stay in one place without moving forward or backward.
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 long can a helicopter stay in th air?
A helicopter can stay in the air until it runs out of fule,oil etc. Or until the engine has some sort of failure ex. like it over heats.
How do helicopter stay aloft in the air?
The rotors provide lift to keep them up.
Which plane is able to stay longer in the sky?
no NO PLANE CAN STAY IN AIR EXPECT HELICOPTER JUST BECAUSE OF HIS WINGS
How does helicopter stay still in air?
The spinning rotor lifts it. The rear rotor stabilises it.
How do you make a paper airplane stay in the air long?
Trial and error. There are many different ways to make a paper aeroplane - some may be better than others.
What floats on the air?
helicopter

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
Why wouldn't a helicopter take off from the moon?
Helicopters require air for lift, and the moon has no atmosphere. Additionally, the moon's gravity is much weaker than Earth's, which would make it difficult for a helicopter to generate lift and stay airborne.
