Two things keep a helicopter flying, and another keeps it flying straight.
To take off:
1) The blades are shaped like the wings of an airplane and create a difference in pressure (high underneath the wing, low above). This difference in pressure "pushes" the helicopter upwards (lift). But because of gravity, however, there might not be enough lift to take off from the ground.
2) In order to take off, the blades must rotate at supersonic speeds (to be stronger than gravity's push downwards), this make it possible to gain altitude.
To "Fly:"
1) A helicopter's blades in air act like a boat's propeller in water. If the blades rotate at an angle, it will start moving. To make the helicopter hover, the blades must be perfectly straight up. At the same time, the rotating blades make the helicopter itself rotate the other way (about the axis of rotation).
In a GPS, the helicopter would not be going anywhere like this (with no angle on the blades), but the Direction at which it is looking will be changing in circles
2) Helicopters need a way to fix this crazy-out-of-control spinning. They can use a tail rotor for this, but they can also use a "twin" set of blades that rotate in opposite directions (counter-rotating blades).
With the addition of counter-spinning blades, now the GPS will be pointing at 1 direction.
in summary:
1) By keeping the blades rotating fast enough to be lifting with the same force as gravity is pushing down, the altitude is kept the same.
2) By keeping the Blades from spinning at an angle, the Helicopter does not move to the sides.
3) By using a counter-rotating blades set, the helicopter is able to keep looking at one direction.
with these 3 things, Helicopter are able to hover in air, and their GPS can be kept and a fixed height, at fixed position on a map, and at a fixed direction.
What else can I help you with?
How would a helicopter remain stationery in air?
A helicopter can remain stationary in the air by adjusting the pitch of its rotor blades. By tilting the rotor blades slightly forward or backward, the helicopter can control its vertical lift and horizontal movement, allowing it to hover in place. Pilots use the helicopter's collective and cyclic controls to maintain a stable position.
When a helicopter is a stationary the blades on both sides of the rotor give the same lift?
Yes, when a helicopter is stationary, the blades on both sides of the rotor produce equal lift. This is necessary to balance the helicopter and keep it hovering in place. The main rotor provides lift by spinning rapidly and creating an upward force that counteracts gravity.
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.
How many syllables is stationary?
There are 4 syllables in "Stationary". Stationary (Stay-Shun-air-ee) 4 syllables
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.
What is the right way to spell stationary?
stay shun air e
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.
Can an airplane be stationary in the mid air?
Airplanes can appear to be stationary to someone on the ground, but they cannot be stationary in the air.
If you stabilize a helicopter in air then can you travel some distance due to the movement of earth?
Yes. Trouble is, most of the air moves with the earth as it rotates(it'be very stormy otherwise) so merely remaining stationary in relation to the air wouldn't help much.
What is a weather front that is standing still called?
Air masses do not stay still for longer than a few days. When a cold air mass and warm air mass meet and do not have enough force to move one another, it is called a stationary front. Stationary fronts can be still, or stay stalled in the same position for a few days.
How would a helicopter remain stationery in air?
A helicopter can remain stationary in the air by adjusting the pitch of its rotor blades. By tilting the rotor blades slightly forward or backward, the helicopter can control its vertical lift and horizontal movement, allowing it to hover in place. Pilots use the helicopter's collective and cyclic controls to maintain a stable position.
What is a nother word for stay in one place?
it is 'stationary', not stationary' as in materials, but 'stationary' as being still or something like that.
