The effect of positive or negative 'g' on autorotation in fixwed wing aircraft?
AUTOROTATION is only for Rotary Wing aircraft...not fixed wing
Why can a helicopter reach a terminal speed whilst falling during autorotation?
GAYS
Why a helicopter falling during autorotation could reach a terminal speed without the pilot changing any controls?
Because Mr moffat likes to suck eggs
Why a helicopter during autorotation could reach terminal speed with out the pilot changing the controls?
Three forces work here. There is gravity, air resistance and the lift force made by the blades autorotation. When the air resistance and gravity forces are equal in strength, this means that the helicopter has reached its terminal velocity. It cannot fall any faster than it is. As the helicopter is using auto-rotation, the pilot does not need to change any controls because the forces will balance out themselves. The helicopter, with the aid of the still spinning blades of the helicopter, will be able to make a safe landing.
What method of dispersal is used by thistle and ash and maple seeds?
Thistle seeds use wind dispersal, with their small, feathery structures allowing them to be carried by the wind. Ash and maple seeds use a method called helicopter or autorotation dispersal, where their wing-like structures allow them to spin and glide through the air.
What happens when the blade of a helicopter stops spinning in the sky?
If a helicopter blade stops spinning in the sky, the helicopter will experience a rapid descent known as autorotation. This is when the airflow through the rotor keeps the blades spinning, allowing the helicopter to land safely even without engine power. It requires skilled piloting to execute successfully.
How was the hummingbird used to invent the helicopter?
The analogy is rather weak, true, Hummingbirds can both hover and fly backwards, they also are among the smallest flying birds and have the highest relative fuel consumption. that"s biology. no hummingbirds have rotors or tail-balancing problems or autorotation clutches, etc. that"s mechanical engineering on the aircraft side. the analogy is rather loose.
How does a paper gyrocopter work?
A paper gyrocopter works on the principle of autorotation. When the paper rotor is spun or dropped from a height, it generates lift due to the air rushing up through it. The spinning motion keeps the rotor blades aligned with the airflow, allowing it to generate lift and descend gently. The gyrocopter does not have an engine but relies on the lift generated by the rotor to sustain flight.
How do you build an autogiro?
Building an autogiro involves several key steps: First, design the airframe to support both the rotor and the propulsion system, ensuring it can withstand aerodynamic forces. Next, construct the rotor system, which includes a rotor hub, blades, and a means for autorotation. Then, integrate the engine and propeller for thrust, along with necessary controls for stability and maneuverability. Finally, conduct thorough ground tests and flight tests to ensure safety and performance before regular operation.
What happen if he blades stop spinning on a helicopter when it is in the sky?
If the rotor blades of a helicopter stop spinning while in the sky, the helicopter will begin to lose lift and descend rapidly. It would enter a condition known as autorotation, where the helicopter can glide down safely by allowing the rotor blades to spin freely due to the downward motion of the aircraft. However, without engine power, the pilot would need to manage the descent carefully to achieve a safe landing. If not handled properly, it could lead to a crash.
What happens if the blades stop spinning on a helicopter when it is in the sky?
If the blades stop spinning on a helicopter while it is in the sky, the helicopter will enter a state known as autorotation. The helicopter will start to descend as the unpowered rotor blades rotate due to the upward flow of air. The pilot must carefully manage the descent and attempt to safely land the helicopter.
