The Bölkow Bo 102 was a stationary helicopter trainer from the German manufacturer Bölkow Developments KG . With the Bo 102, a GRP rotor blade was used for the first time in a helicopter , which was intended for longer idle times.
history
According to the plans of the designer Ludwig Hofmann , a ground-based education and training device was developed in the mid-1950s, which should minimize the risks involved in training helicopter pilots and reduce operating costs by 7/8. After completing a 500-hour endurance test, five copies of the device were delivered to the Bundeswehr in 1959 . The Heli-Trainer was also used in France (2), Great Britain (2), Spain (5), Italy (2) and Yugoslavia (1).
construction
The Bo 102 essentially represented a single-seat helicopter permanently attached to a damping frame. The frame could also be placed on a circular float (rubber bead) so that horizontal movements were also possible.
The helicopter part had a single-wing glass fiber reinforced GRP main rotor with a semi-rigid suspension and a diameter of 6.57 m. A 29 kW (40 hp) three-cylinder two-stroke engine ILO L 3x375 was used as the drive. The power was transmitted to the rotor via a planetary gear with freewheel. The single-blade tail rotor was driven by an intermediate gear for torque compensation .
The entire frame as well as the fuselage frame was designed as a welded tubular steel construction. The pilot's seat had a large windshield. Normal helicopter controls and basic instrumentation were used.
The two fuel tanks together held 66 l; the total weight was 720 kg, including the float, fuel, students and the teacher sitting outside the cabin.
The free-flying training helicopter Bo 103 , which used the structure of the Bo 102, was experimentally derived from the trainer .
