Helicopters

Helicopters are not very well suited to high altitude flight. By their very nature helicopters less suited for high altitudes than airplanes or balloons. Additionally, since the most common usages of helicopters deals in short hops or other low-altitude duties, modern helicopters aren't designed with high altitude flight in mind.

The stratosphere is generally agreed to start at about 30,000 feet altitude. While this is pretty near to the helicopter altitude record (in 2005 an Ecureuil/AStar AS 350 B3 helicopter landed on Mount Everest (29,035 feet)) This is far higher than the ceiling of the average helicopter (10 to 12,000 feet).

No, a helicopter cannot take off from the moon because there is no atmosphere to generate lift for the rotor blades to work. Helicopters rely on air density to generate lift, and the lack of atmosphere on the moon makes it impossible for a helicopter to fly.

on a heading indicator there are 360 degrees, North being 0, East being 90, South 180, and West 270, the helicopter's flying SW, and is therfore in the middle of 180 and 270, so your answer is 225 degrees

This is the tree's transport system. The leaves spin away from the mother tree in order to land and plant far enough away from the mother tree. This way, the seed can grow without being smothered out by roots or lack of water. If you pick a leaf too soon, you will see that it's slippery, pink leaf is too heavy and will not spin. Only when leaf dries out does it create the surface area plus light weight to spin. Thus, the wind shakes it from the tree, and ZOOM...the leave with the seed detaches and flies like a helicopter.

Helicopters struggle at high altitudes due to reduced air density, which decreases lift generation, engine performance, and rotor efficiency. Furthermore, the lower air pressure makes it harder to control the aircraft, affecting its stability and responsiveness.

A helicopter blade works the same way as a wing on a fixed wing aircraft. The air flowing faster over the top of the airfoil generates lift. When a helicopter flies at a high altitude the air gets thinner. Because the air is thinner, more pitch on the blades is needed to keep the helicopter in the air. When too much pitch is on the blades the blades stall, air moves past the bottom of the blade and creates a vortex behind the top of the blade. All lift is lost and you lose altitude.

Using earth leads during helicopter refuelling can help to prevent static electricity buildup and reduce the risk of sparking which could ignite fuel vapors. By grounding the helicopter to the earth, any static charges that have accumulated can safely dissipate, ensuring a safer refuelling process.

No, the F-35 does not need to have taxiways or runways to take off or land but it can use those to to move if the F-35 wanted to but the F-35 can take off vertically without runways.

The fastest speed of a medical helicopter can vary depending on the model and manufacturer. However, most medical helicopters have a cruising speed of around 150-160 mph (240-260 km/h) and a top speed of around 180 mph (290 km/h).

A helicopter typically contains elements such as a main rotor, tail rotor, engine, fuselage, landing skids or wheels, and a cockpit where the pilot controls the aircraft. They also have various systems like avionics, hydraulics, and fuel systems.

Rotor helicopters work by generating lift through the rotation of large horizontal blades called rotor blades. As the rotor blades rotate, they create a pressure difference between the top and bottom surfaces of the blades, producing lift. By altering the pitch of the rotor blades and controlling the speed of rotation, pilots can steer the helicopter in different directions.

A helicopter experiences drag through air resistance as it moves through the atmosphere. The main sources of drag in a helicopter are profile drag from its overall shape and skin friction from the airflow over its surface. Additionally, rotor tip vortices and induced drag generated by the rotor system contribute to overall drag.

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.

A helicopter typically has mechanical energy in the form of both potential energy (stored energy due to its position) and kinetic energy (energy of motion as the rotors spin).

The higher you are from the Earth's surface - the lower the air pressure is. Helicopters are heavy machines - requiring a huge amount of effort from the rotor blades to keep it airborn. The lower the air-pressure, the harder the rotors have to work to keep the craft flying.

The shape of the blade of a paper helicopter can affect its flight by influencing factors such as lift and drag. Blades with a larger surface area or more angled design may generate more lift, while blades with a streamlined shape may reduce drag, resulting in longer flight times. Experimenting with different blade shapes can help optimize the performance of a paper helicopter.

Rapid response wiring involves direct electrical connections that enable quick and precise transmission of signals from the pilot's brain to the helicopter controls. This allows the pilot to make instantaneous adjustments in response to changing conditions, such as storm-strength winds, without any delay or lag in communication. This enhances the pilot's ability to maintain precise control over the helicopter, improving safety and maneuverability in challenging environments.

Rotocopters work by spinning rotor blades to generate lift. The weight of the rotocopter is supported by this lift force, which must be greater than the weight for the rotocopter to stay airborne. Drag is generated as the rotocopter moves through the air, which must be overcome by thrust generated by the rotor blades to maintain forward motion.

The size of a helicopter blade affects the speed of rotation by determining the amount of lift generated and the amount of drag produced. Larger blades tend to generate more lift but also experience more drag, which can impact the speed of rotation. Adjusting the blade size can help optimize the balance between lift and drag to achieve the desired speed of rotation.

A helicopter typically uses mechanical energy by converting the power from its engines into rotational motion of the rotor blades to generate lift and thrust for flight. Additionally, the engines in a helicopter can run on various fuel sources such as gasoline, jet fuel, or diesel, which provide the energy needed for propulsion.

A helicopter typically uses various forms of energy, including chemical energy from the fuel used to power the engine, mechanical energy in the rotating components like the main and tail rotors, and kinetic energy as it moves through the air.

A helicopter Pfeiffer damper works by using a rotating pendulum attached to the rotor head. The pendulum moves in response to changes in the rotor system's orientation, providing a counteracting force to reduce vibrations. This helps stabilize the helicopter during flight and improves overall control and handling.

The rotor blades of a helicopter are tilted backwards when rotating to generate lift and control the direction of the aircraft. This tilt is called "pitch" and is controlled by the pilot using the cyclic control stick to adjust the blade angle as needed during flight. The pitch of the rotor blades can be changed to move the helicopter forward, backward, left, or right.

Helicopter blades are balanced by adjusting their weight distribution to ensure that the center of mass is aligned with the rotational axis. They go through a process of dynamic balancing where weights are added or removed to minimize vibrations during flight. This process helps to improve performance and increase safety for the helicopter and passengers.
