What Is a Helicopter? NASA

Most helicopters have a single main rotor but require a separate rotor to overcome torque. This is accomplished through a variable-pitch antitorque rotor or tail rotor. This is the design that Igor Sikorsky settled on for his VS-300 helicopter, and it has become the recognized convention for helicopter design, although designs do vary. When viewed from above, most American helicopter rotors turn counter-clockwise; French and Russian helicopters turn clockwise. WebHelicopter engines can be either piston or gas turbine turboshaft. Air is drawn in, compressed, mixed with fuel, ignited, then the rapid expansion of the gas is harnessed to turn a drive shaft which is fed to the main transmission. The engines use gasoline (Avgas) or Kerosine (Jet A1) to power them. WebA wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of … theoretical probability lesson tes

WebApr 12, 2024 · Propeller blades are fixed to their hub at an angle, just as the thread on a screw makes an angle to the shaft. This is called the pitch (or pitch angle) of a propeller and it determines how quickly it moves you forward when you turn it, and how much force you have to use in the process. WebJul 21, 2024 · The work done to keep the helicopter hovering is that generated by the motion of the rotor blades as they move through the air. The two key notions that go into the calculation of this work are lift and drag. Lift is the upwards-pointing force that balances gravity and keeps the helicopter hovering.
