The BO 105 is a five-place, multi-purpose utility helicopter having a hingeless, four-bladed main rotor and a semi-rigid two-bladed tail rotor. The main and tail rotor blades are constructed of fiber-reinforced composite materials.The helicopter is powered by two Allison 250-C20 series engines of the free wheel turbine type. The engine power is transmitted by the main rotor transmission via independent drive systems.The main transmission consists of three major subassemblies, in which two bevel gear input stages with freewheel clutches, a spur collector gear stage and a planetary reduction stage are housed.The total fuel quantity is stored in three flexible bladder-type tanks, two main tanks (forward and aft) and one supply tank, all installed in the tank compartment beneath the cabin floor.
