| 1. | Therefore, a gearbox is inserted between the rotor hub and the generator.
|
| 2. | Two General Electric J35 turbojet engines were used, sending bleed air up through the rotor hub.
|
| 3. | They positioned the rotor hub directly over the wing centre line and behind the centre of gravity.
|
| 4. | The two-bladed wind turbine with flexible or teetered rotor hubs characterized the NASA-led program.
|
| 5. | A crash in February 1926, caused by blade root failure, led to an improvement in rotor hub design.
|
| 6. | The European 200SX initially had 257mm front brakes and rear disc service brakes with drum parking brakes in the rotor hubs.
|
| 7. | The cause of the crash was due to fatigue failure of a swashplate carrier driving link in the front rotor hub.
|
| 8. | The collective, cyclic, and differential controls were enclosed in the rotor hubs and ran in an oil-bath.
|
| 9. | This loss can be minimized by increasing the distance between the two rotor hubs, and by elevating one hub over the other.
|
| 10. | Because lift increases with speed, the outermost sections of the rotor blades generate more lift than those parts closer to the rotor hub.
