| The propeller or the jet engine of an aircraft pushes air backwards to propel the aircraft forward. |
| The second person who died was the guy organizing the wind machine, which was a propeller from an old Russian plane. |
| Turbine generators here wind down, the emergency system to protect the nuclear reactors from overload kicks in, and the propeller shaft stops. |
| These aircraft were pulled into the air nose first by a large propeller and when airborne would level out into horizontal flight. |
| Behind the cross, crude propeller blades on whirligigs made by local artist R A Miller and planted on Windy Hill, spin and twirl on gusty days. |
| Once airborne the rear-mounted propeller pushes the craft along and the unpowered main rotor spins to give the craft lift. |
