Each company divided the cost for developing the new helicopter with the final assembly taking place in Germany. Various parts of the helicopter were produced at each company. Among the parts produced by MBB were the rotor head, rotors, and tail section. Kawasaki produced, among other parts, the transmission, main fuselage, and fuel system.
The BK 117 Helicopter was heavily based on its military predecessor, but the military version did not sell. However, its civilian version has had a few military buyers. The helicopter became very popular for medical transport, search and rescue work.
The 1985 Paris Air Show featured a military version of the BK 117 Helicopter produced as an attack and anti-tank helicopter. Eventually the military of some twenty countries purchased the civilian version of the BK 117, and none use it in an attack role.
The BK 117 Helicopter is most popular with hospitals, police and fire departments around the world. It has found other uses as a civil and military transport helicopter, plus the lifting of light to medium loads where larger helicopters would be difficult to maneuver.
The cabin of the BK 117 Helicopter typically can accommodate nine passengers as an air taxi. Six can be seated comfortably when the helicopter is used as a VIP transport.
The rotor head of the BK 117 Helicopter is made from titanium and is similar to the one used by its military predecessor. The rotor blades are made from a glass-fiber composite with a hardened stainless steel leading edge. Although similar in shape, the blades are about four feet longer than those of its military predecessor. For storage in tight spaces, two of the rotor blades can be folded.
Although normally equipped with skids, wheels, skies, or pontoons can be fitted to the BK 117 Helicopter.
A total of 443 BK 117 Helicopters were built before production ended in 2004.
