1.6 GENERAL DESCRIPTION OF THE HELICOPTER
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.
Engines
The helicopter is powered by two Allison 250-C20 series engines of the freewheel turbine
type. The engine power is transmitted to the main rotor transmission via independent
drive systems.
Transmission
The main transmission consists of three major subassemblies in which two bevel gear in-
put stages with freewheel clutches, a spur collector gear stage, and a planetary reduction
stage are housed.
Fuel Tanks
The total fuel quantity is stored in three flexible bladder-type tanks, two main tanks (for-
ward and aft) and one supply tank, all installed in the tank compartment beneath the cabin
floor.
