What does rotor blades mean?
Rotor blades are on helicopters. They are the long narrow parts above the fuselage (cabin) .When these rotate they impart 'lift' to the helicopter.

How does a tilt rotor land?
As a helicopter. The blades on the V-22 Osprey are much too long for it to land as a conventional airplane would.
How long is the apache helicopter blade?
The Apache helicopter, specifically the AH-64 Apache, has rotor blades that are approximately 11.6 meters (38 feet) long. These blades are designed for optimal performance, enabling the helicopter to achieve high maneuverability and speed. Their length contributes to the aircraft's ability to generate lift and stability during flight.
How helicopter flies?
First you need to understand lift and how it is generated. If you do a google image search for "airfoil" you can see what it looks like. The top has a curve to it and the bottem is flat. As the airfoil passes through the air, lets say at a speed of 1, the air going over the top of the airfoil must travel at a higher rate of speed, maybe 1.5, that the air giong under the flat bottem. This is known as Bernoulli's Principle or lift. Now, if you take 2 or more long thin airfoils or blades and attach them to a center mast and provide a means for them to tilt and twist you have a basic rotor head of a helicopter. As the blades are spun through the air they create lift, much like if you have your hand out the car window. If you incrase the pitch of the blades by twisting them so the front edge goes up you get more lift and the helicopter goes up. If you tilt the blades to the left, fore example the helicopter will go left. Everything has an equal and opposite reaction. In this case if you turn the rotor blades to the left or counter clockwise the body of the helicopter (fusealage) will want to turn to the right. This is where the tail rotor comes into play. It pushes air to the left to keep the fusealage from turning. If you want to turn the helicopter to the left then you would incrase the pitch of the tail rotor blades to over come the twisting force of the helicopter. To turn to the right you would reduce the pitch of the tail rotor blades and let the helicopter twist agians the main rotor.
How does a helicopter rise into the air?
Simple answer: By blowing air at the ground. Long answer: Air moving in the right way can have immense force behind it. Hurricanes can flatten trees, tornadoes can pick up cows and jet aircraft can use a directed jet of air to propel itself. The Rotor blades of a helicopters are like a massive, high powered fan that blows air downwards. Each rotor blade has an airfoil profile (similar shape to the cross section of an airplanes wing), so as the rotor blade turns it generates lift, just like an airplanes wing. The when the blades turn fast enough the lift forces will be greater than the forces of gravity. The pilot can control this by altering the angle of the blades. As the pilot increases the angle of the blades, more lift will be generated. In practice all helicopters do not have much variation in rotor speed during flight, and the rotor speeds are a lot slower than most people realise. But there's a problem known as Torque Reaction. If you just have a single main rotor, then as the helicopters blades starts to get to a state where lift from the blades equal the forces of gravity, the helicopter will start to spin on the spot. (A visual thing to see this in action is watch the film Black Hawk Down, when the helicopter gets shot and loses its tail rotor). To balance the forces induced by torque reaction, most helicopters have a tail rotor at the end of the tail boom. The tail rotor blades have a variable angle controlled by the pilot, like the main rotors. Adjusting the angle of blades will balance the forces of torque reaction. Altering this angle in a hover will allow the helicopter to turn on the spot.
What are the two basic gyroscopic characteristics possessed by a helicopter rotor system?
Precession: The rotor disc tilts in the direction of the force applied, 90 degrees later. Rigidity in Space: The rotor disc stays in a fixed plane as long as the helicopter is spinning.
What did the helicopter look like?
A helicopter has two blades on the top of the body. The body is an oval sort of shape. It also has a long tail on the back to keep the helicopter balanced. LOLZ I hope you got the ANSWER you where looking for!!!
How does a bell helicopter take off?
Pushing Air downwards to fly. Rapidly spinning long, thin blades push air downwards to lift the helicopter up
What safety measures should be taken when working near a helicopter with a long pole hanging down?
When working near a helicopter with a long pole hanging down, it is important to follow these safety measures: Maintain a safe distance from the helicopter at all times. Wear appropriate personal protective equipment, such as a hard hat and high-visibility clothing. Communicate effectively with the helicopter pilot and ground crew. Be aware of the rotor blades and the potential for sudden movements of the pole. Follow all safety protocols and procedures provided by the helicopter operator. By following these safety measures, you can help prevent accidents and ensure a safe working environment near a helicopter with a long pole hanging down.
A paper helicopter that has the most hang time?
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.
How long is a rotor blade of a wind turbine?
The length of a rotor blade on a wind turbine can vary depending on the turbine size and design. On average, rotor blades can range from 116 to 328 feet (35 to 100 meters) in length for utility-scale turbines.
