Bolkow Bo.108

 

Bolk-Bo-108-2


The Bo.108 is a flight test vehicle for advanced systems This also includes subsystems integrated into a new airframe. The first of two prototypes (D-HBOX) first flew on 15 October 1988 powered by two Allison 250-C20R turboshafts.. The helicopter initially undertook a flight test programme to assist in the advance of helicopter technology particularly in rotor technology, and the development of dynamic systems, anti-resonance isolation systems, composite structures, electrical and avionic systems, cockpit installations and engine integration.


Fitted with higher-powered Turbomeca TM-319 Arrius IBs engines and equipped with a single-pilot EFIS-based IFR system, the second prototype, nominally stretched by 15cm, flew in June 1991.


The Bo.108 was equipped with two Allison 250 C20-R engines but the engine compartment had been designed to allow other power units such as the Turbomeca TM319 or the Pratt & Whitney PW205B/1.
