Do the rear blades of a helicopter lift the helicopter?
NO, the main rotor does the lifting and the small rear propeller is used to stop it spinning around and help with steering it.
How the rotor is made to turn in a helicopter and in an auto gyro?

Why do some helicopters have a small tail rotor?
Tail rotors are to correct the effect of engine torque and help steer the helicopter
How does a girocopter work?
Ok...its gyro-copter to start lol. They differ from helicopters in that they are in "Auto rotation" all the time during flight which means the relative wind blows through the rotor causing lift from the underside. An engine driven pusher propeller is used to push the gyro into the wind, hence causing the main rotor to turn and generate lifting forces. In a helicopter, the engine directly drives the main rotor and the tail rotor. The tail rotor is used to offset the huge torque from the main rotor in the helicopter. The gyro does not need this torque corrector as the main rotor is freewheeling and has a rudder in place of a tail rotor for directional control. When a helicopter engine fails, it must drop a good distance to have the main rotor pick up enough speed to help flair for a lesser crash impact. The gyro is already in auto rotation and hence needs a much much less drop in altitude to keep up rotor speed for a safe landing.
Why are tail rotors perpendicular to the main rotor?
Because without a tail rotor the body of the helicopter would spin the opposite way of the main rotor so the tail rotor is perpendicular to prevent that : Way it works is the tail rotor spins at the same speed as the main rotor to over power the body's need to spin by giving just the right amount of need to go the other way : Hope I Helped , jd703
How autorotation is used to help land a helicopter safely if the engine fails?
Autorotation is a flight maneuver that allows a helicopter to land safely in the event of an engine failure. During autorotation, the pilot lowers the collective pitch, allowing the rotor blades to continue spinning due to the upward flow of air through the rotor system. This creates lift and allows the helicopter to descend in a controlled manner. The pilot then manages the descent rate and performs a flare just before landing to reduce vertical speed and ensure a safe touchdown.
94 Cheyenne 305 won't start new rotor ignition module coil plugs and wires rotor is turning but still wont start checked fuel system please help?
do you have spark, is the timing set correctly, do you have injector pulse?
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.
How does the helicopter do to help the environment?
they help in fighting fires.
What is the terminal velocity of a helicopter?
Terminal velocity is generally associated with a falling object, not a powered one. Therefore I must assume that the helicopter has experienced Engine/rotor failure. Rotor failure is important because even unpowered, the rotor can be used (auto-gyro) to safely land.Let's supposed the rotors have been blown off. The falling body of the helicopter will reach a 'Terminal Velocity' of between 100 and 140 mph, depending on its Drag value. Its drag value will depend on its shape and size.
How does wind help a helicopter fly?
it does
