| 41. | The annular air intake surrounded a reduction gear for propeller drive takeoff, and the exhaust duct was also annular.
|
| 42. | Engineers reused the reduction gear from the Type 81, enabling the 1.5 ton van to use a flat four engine.
|
| 43. | The cross connect gear splits the power from the gas turbine via both main reduction gears to the two shafts.
|
| 44. | The prototype was powered by a Gnome Omega driving a three-bladed aluminium propeller through a 2 : 1 reduction gear.
|
| 45. | But the reduction gears, which take up a tremendous amount of space and are difficult to maintain, will be gone.
|
| 46. | This eliminated the noise from the main reduction gears, but the cost was to have a huge main propulsion turbine.
|
| 47. | Much like the Ferret, rear wheel drive is transmitted directly to epicyclic hub reduction gears, also known as bevel boxes.
|
| 48. | Each axle was powered : the traction motors were axle hung, nose suspended, driving the wheelsets via a single reduction gear.
|
| 49. | Engine No . 2 also received the new style cylinder banks and was tested both with and without the reduction gear.
|
| 50. | A notable feature of the Pobjoy R was the propeller reduction gear which allowed the small engine to operate at more desirable higher speeds.
