Helicopters

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.

No, helicopter blades do not break the sound barrier. The tips of the blades can approach the speed of sound, but the entire blade does not exceed the speed of sound.

Depending on the make of the helicopter, some will rotate clockwise and others will rotate counter-clockwise. However, the main rotor and tail rotor will spin opposite of each other. If the tail rotor spins clockwise, the main rotor will spin counter-clockwise. The main rotor also spins for lift, the tail rotor for control.

The main rotor on a helicopter creates lift, which allows the helicopter to become airborne and maintain its altitude during flight.

Weight affects the hang time of a helicopter by influencing its lift capacity and fuel consumption. A heavier helicopter will require more power to generate lift, which can reduce hang time. Lighter helicopters are generally more maneuverable and efficient, resulting in longer hang times.

To improve the hang time of a paper helicopter, you can try adjusting the weight distribution by adding paper clips to the body to help it float longer. Additionally, trimming the blades to ensure they are balanced and have a larger surface area can also increase the hang time. Finally, experimenting with different folding techniques and angles of the blades may also help optimize the helicopter's performance.

Yes, the length of the wings can affect the speed of a paper helicopter. Longer wings typically provide more lift and stability, which can result in a smoother and potentially faster descent. However, other factors like weight distribution and design also play a role in determining the overall speed of the paper helicopter.

Because as you increase altitude, the density of air decreases. To compensate for the decreased air density the rotor blades need a greater angle of attack, pushing the retreating blade closer to stall(reducing the maximum airspeed)

Because the air is thinner there is less air for the rotors to push down on.

The long standing world record at the current times is held by aerospatiale test pilot Jean BoUlet who flew the M1-12 lamma to a height of 40,005 ft, On the same flight he also grabbed the record for longest autorotation ever in a helicopter, as the engines failed as soon as he lowered the power due to the extreme colded and lack of air into the engine.

The tail rotor is moving "perpendicular" to the main rotor, not "opposite".

The tail rotor creates thrust opposite to the thrust of the main rotor, to keep the fuselage from spinning.

Most helicopters spin the main rotor counter-clockwise looking from above, which puts a clockwise rotation on the fuselage. You need a tail rotor pushing the tail counter-clockwise to keep the fuselage pointed in the direction the pilot chooses.

All aircraft, not just helicopters, have wind limitations. Essentially they are placed so that structural limits will not be exceeded. If too much wind force is exerted on part of an aircraft that is not strong enough to withstand that force then a catastrophic failure could occur.

The lift/propulsion method used by a helicopter is capable of producing an overall thrust vector with virtually no horizontal motion. The lift method of planes (fixed wing), requires movement to produce lift.

There are many possible helicopter configurations - most designs use some variation of multiple rotors placed in such a manner that rotational force is compensated for, allowing stable flight. Lift is able to be generated because the rotors (which are essentially just spinning wings) are still moving through the air, while the airframe overall stays in the same place.

According to Infinity specifications the fuel capacity is 20.0 Gallons

A helicopter pilot can increase lift by increasing the pitch angle of the main rotor blades or by increasing the collective pitch angle, which changes the angle of attack for all blades simultaneously. This increases the helicopter's vertical thrust and lift.

A helicopter creates lift through its main rotor blades, which generate lift by spinning rapidly and creating a pressure difference between the top and bottom of the blades. This pressure difference causes air to flow over the rotor blades, creating lift that allows the helicopter to become airborne.

To calculate the horsepower used by the helicopter, you first need to convert the lifting work into units of power (horsepower). The formula to calculate power is: (Force * Distance) / Time. In this case, you would calculate (800 lbs * 200 ft) / 1 min to get the power in foot-pounds per minute. To convert that to horsepower, you would divide by 33,000 (the number of foot-pounds per minute in 1 horsepower).

Helicopters require at least two propellers to achieve stability through a concept known as "counter-torque". The main rotor produces torque that would rotate the body of the helicopter in the opposite direction. The tail rotor or fenestron is used to counteract this torque, providing stability by keeping the helicopter from spinning uncontrollably.

A helicopter achieves lift through its main rotor blades, which spin rapidly to create lift by generating airflow over the rotor blades. The shape of the rotor blades and the angle of attack can be adjusted to control the lift produced. This lift overcomes gravity, allowing the helicopter to become airborne.

A helicopter moves forwards by the rotors spinning, and being slightly tilted. So if the rotors are flat, it will hover. This is because the air being pushed by the rotors is going straight down, not onto another surface, thereby making it go forwards.

the answer to this question is pull it is the opposite to push.push is the force that makes it go forward and pull is the force to bring you back...go liverpuddlians:):):):):):):):):):):):):):):):):):):):):):):):):):):):):):)

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. :)

The rotor blades on a helicopter work the same way as wings on a fixed wing aircraft. The air passing faster over the top of the airfoil generates lift. Helicopter rotors spin so that the lift is generated without having to have forward airspeed like a fixed wing aircraft.

I've never heard that. However, helicopters are limited to the altitude that they can hover, which would limit a Rescue helicopter from picking up a stranded mountain climber. In the high altitude, the air is "thinner" which means the air pressure is less. This limits the effiency of the rotor blades. However, usually the first indication of a problem is when a helicopter tries to hover at high altitude and the tail rotor looses it thurst and the helicopter goes into an uncontrolled spin. This was common with the Bell Model 206B. Even though a helicopter may be limited to the altitude at which it can hover, that does not mean it can't fly at that altitude. If a helicopter maintains a high forward air speed, it can still fly over mountains; its only when it stops and hovers that it may have problems.

Helicopters generate lift and thrust through the rotation of its main rotor blades. By changing the pitch of the blades, the helicopter can control its altitude, direction, and speed. Additionally, the tail rotor is used to counteract the torque created by the main rotor to keep the helicopter stable.
