MBB’S BO 108 DESIGN AND DEVELOPMENT

In 1983, the MBB-Helicopter Division started design and development of a new light-twin, multipurpose helicopter, now designated as the BO 108. After an intensive phase of technology investment, many technology advances were incorporated into the design, in order to meet the many advanced characteristics required within the future market. The aircraft (prototype 1) flow for the first time in October 1988, and has accomplished about 85 flight test hours so far. This paper illustrates the design requirements, and reviews the technology advances in terms of the various components involved (rotor systems, drive system, anti-vibration system, control system, airframe, cockpit and cabin). It gives an overview about the current status of bench and in-flight testing and assesses the progress achieved in the fields of performance, flying qualities, noise and vibrations, weight, reliability and safety. Studies for increasing the aircraft’s capabilities are described and a prospective about the future program plans is also given.
