What else can I help you with?
Is an autogyro different than a helicopter is corectly written?
In an autogyro, the main rotor is freewheeling, it is not powered as in a helicopter.
Is the top part of a helicopter a propeller or wings?
It is called a rotor, and it more closely resembles a wing than a propeller blade
How do helicopters go forward?
Helicopters move forward primarily through the tilting of their rotor blades. When the pilot adjusts the cyclic control, it changes the angle of attack of the rotor blades, causing them to generate more lift on one side than the other. This uneven lift tilts the helicopter forward, allowing it to move in the desired direction. Additionally, the rotor blades generate thrust, propelling the helicopter forward as they rotate.
How is it to fly a helicopter?
Much more complicated than a fixed wing aircraft. -Military helicopter pilots in most services MUST qualify as fixed wing pilots before graduating to helicopters.
What happens to the advancing blade of a helicopter?
The "advancing blade" of a helicopter refers to the side of the rotor which moves forward in relation to the fuselage. As each rotor blade makes a full circle around the center, on one side of the swing, it moves forward, and on the opposite side it is moving towards the rear of the helicopter. When the helicopter is moving forward in air, the rotor blades on the advancing side are moving at a higher airspeed than the rotor blades elsewhere. Rotor speed + aircrafts forward airspeed. This results in slightly more lift on that side. Conversely the exact opposite is happening on the other side where you get Rotor speed - aircraft forward airspeed. This creates a tendency for helicopters to want to roll at high airspeed. This is one of the many odd tendencies of rotor aircraft that pilots are constantly adjusting to balance out.
How does a tandem helicopter steer?
There is a part on a helicopter that is called a swashplate, it converts non rotating controls into rotational movements via an inner ring riding on a bearing attached to an outer ring that is able to pivot on the shaft. On a tandem helicopter it uses both of them in unison most of the time. A helicopter maneuvers by adjusting the pitch of the blades to be more biased to one side, basically pushing air at an angle, causing it to go the opposing direction. So when a tandem rotor helicopter wants to fly forward it pitches both (or even one depending on what you want to do with it exactly) to fly forward. This all applies to the cyclic (steering). For yaw (turning) they either tilt the back only (to pivot around the front rotors), the front only (to pivot around the front rotors) or both (to pivot around the center). with the joy stick!!!!!!!! A helicopter with twin main rotors steers by flying the rotors just as a single rotor helicopter would do to make a turn. A single rotor helo uses the main rotor to tilt and bank. For a twin rotor helo, the two rotors do the same but can pivot the helo about its axis. The controls are a bit more complex than for a single rotor.
Is a helicopter more reliable than a plane?
Due to the complexity of a helicopter, it requires MORE maintenance than a fixed wing aircraft of a similar size. Having flown both, I would consider a helicopter less reliable,
Why rotor slots is more than stator slots in induction motor?
rotor slot more. it is to get a large rotor inductance value of inductance the stator windings
How much torque does tail rotor needs to work?
The amount of torque required by a tail rotor depends on factors such as the size and weight of the helicopter, the speed at which it's flying, and external forces like wind. Generally, tail rotors are designed to provide enough torque to counteract the torque produced by the main rotor and maintain stable flight.
How do counter rotating propellers on a helicopter increase the lift?
Counter rotating blades on a helicopter are used to replace the traditional tail rotor found on most aircraft. Because the blades oppose each other (and therefore cancel out the torque created by the other blade) a tail rotor is not necessary. This allows all of the engine's power to be used for lift rather than powering the additional rotor.
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 should I know before having the rotors on my car replaced?
When having the rotors on your car replaced, ask for a higher quality metal type of rotor. Inferior types can squeak and not dissipate heat well, causing problems sooner than you'd expect them to. A rotor must be replaced, instead of resurfaced, once the thickness specifications for the automobile and rotor brand are not being met. In Addition, if a rotor is cracked, warped, already resurfaced, or otherwise damaged it must be replaced. Many times drums, pads, and other automobile parts will have to be replaced if the mechanic sees problems once the old rotor is removed. A rotor replacement should not take more than one day and should not cost more than $100 for parts and labor at home, or over $400 at a repair shop.
