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.
