Mbb/Airbus Helicopters Bo105

Twin Rotorcraft

The MBB BO105 is a light twin-engine helicopter that made aviation history in 1967 as the first light rotorcraft with a rigid titanium-composite main rotor head, eliminating the need for flapping hinges and delivering exceptional agility. Designed by Messerschmitt-Bölkow-Blohm in West Germany and first flown in 1967, the BO105 became famous for its ability to perform aerobatic maneuvers, including loops and rolls, that were previously impossible for helicopters of its class. Its hingeless rotor system provided unmatched responsiveness and control authority, making it a favorite for demanding missions where precision mattered. Powered by two Allison 250-C20 turboshaft engines, the BO105 seats up to five including the pilot and cruises at approximately 130 knots with a service ceiling around 17,000 feet. The type found its niche in emergency medical services, law enforcement, and corporate transport across Europe and North America, prized for its hot-and-high performance and compact footprint. Military variants served with armed forces worldwide, including the German Army's PAH-1 anti-tank version equipped with HOT missiles. Over 1,400 examples were built before production ended in 2001, with many still flying today in utility and air ambulance roles. The BO105's rigid rotor technology directly influenced later Airbus Helicopters designs including the BK117 and EC135, cementing its legacy as a pioneering platform that redefined light helicopter capabilities. Its combination of ruggedness, maneuverability, and twin-engine safety made it a workhorse in challenging environments from Alpine rescues to offshore oil platforms.
