1
Both the small propellers and the main rotor are powered by the twin turbine engines.
2
The main rotor was building up speed, and McGarvey had to cup a hand over his earpiece.
3
The container sailed through the air until it floated into the path of the main rotor blades.
4
A bullet pinged off the main rotor.
5
The first landed safely but the tail rotor of the second helicopter hit the parked helicopter's main rotor.
6
Another important result derived here is the association between the number of main rotor blades and likelihood of accidents.
7
It's main rotor disintegrated on coming into contact with the ground while the tail rotor hit a low wall.
8
McGarvey and Pete hurried around to the front of the chopper, ducking low as the main rotor began turning.
9
If the engine fails, the craft still can land safely thanks to the lift generated by its auto-rotating main rotor.
10
As soon as the main rotor began to spin, its tip buzz-sawed against the windowpane, jarring the room with a grating vibration.
11
As the helicopter descended the left-hand rear side of the main rotor disk struck a six metre high lamppost, causing it to spin.
12
Satisfied with that, his left hand played with the pitch control, changing the pitch of the main rotor and bringing the bird down several feet.
13
The wash from his main rotor, and theirs, flattened the water below them, pushing it out into little, rimmed and smooth ponds within the sea.
14
The X2 uses a coaxial main rotor system, eliminating the need for the tail rotor that typically counters the torque of a single main rotor.
15
The hoist cable snapped after it became snagged on the Conningbeg lightship off the Saltee Islands and the recoil smashed in the main rotor blades.
16
Where a helicopter uses its main rotor for propulsion and lift and the rear rotor for balance, the gyrocopter gets propulsion from a rear propeller.
