The Cabri G2 is a single-engine, two-seat helicopter made by the French manufacturer Hélicoptères Guimbal with a piston engine drive .
history
The idea and the development of the helicopter was initiated as a private project by the engineer Bruno Guimbal, who was then employed by Aérospatiale , in the 1980s. From the beginning of the 1990s, the development and testing of the project was officially supported by Aérospatiale (later Eurocopter ).
Guimbal Cabri explains the name as an acronym formed from C omfort in A utorotation B elongs to R otor I nertia . The prototype of the Cabri G2 had its maiden flight in April 1992. When Eurocopter decided against the certification and serial production of the model, Guimbal reached an agreement with the group and in 2000 founded his own company, Hélicoptères Guimbal SA. From now on, Guimbal worked on the certification of the Cabri and received approval from the European approval authority EASA according to CS-27 on December 14, 2007 and approval from the FAA on February 3, 2015 . The Cabri is intended to compete with the Robinson R22 . The price quoted is EUR 275,000. The gmbh Baden-Baden motorflug , a subsidiary of Eurocopter , received her first helicopter (D-HETA), with the serial number 1007 on 24 November 2009. The machine is there the pilot training. The Cabri G2 also holds some world records in various categories in its class.
Orka-1200
The UAV Orka-1200, which was developed by Hélicoptères Guimbal together with EADS Defense and Communications Systems , is also based on the Cabri G2 .
Helicopter trainer
Together with the Max Planck Institute for Biological Cybernetics and a helicopter operator based in Augsburg , a flight simulator with the fuselage of the G2 was developed. The fuselage was mounted on a heavy duty robot KR 500 TÜV from the Augsburg company KUKA Roboter and is able to simulate all movements of a helicopter. The Heli Trainer was presented to the public at the International Aerospace Exhibition Berlin 2010.
technology
The conventionally constructed helicopter is made of composite materials , with the fuselage being manufactured by Composites Aquitaine ( Sogerma ). It has an empty weight of less than 500 kg and is equipped with a three-bladed main rotor with blades made of carbon fiber reinforced plastic with a lead core, flapping and swivel joints with elastomer bearings and dampers, and a seven- bladed Fenestron rear rotor. The main rotor turns clockwise when viewed from above.
The G2 is powered by a 107 kW (145 PS) Lycoming O-360 -J2A four-cylinder boxer engine . The engine is the same as that of the Robinson R22, but has an additional Plasma II + ignition system from the US company Light Speed Engineering, which increases the output from 131 HP to 145 HP. This drives an intermediate shaft via a belt with a reduction ratio of i = 0.855, which in turn drives the main rotor shaft via a bevel gear with i = 0.234 (11:47). Thanks to the 170 liter tank, flights of 930 km or up to five hours are possible. Particular emphasis was placed on the helicopter's crash safety and low operating costs (for example due to the long idle times of the drive train). The cockpit is equipped with a modern multifunctional display. A noise level of 75.7 decibels is reached in the flyby .
Incidents
The machine of motorflug baden-baden gmbh (see above) crashed on April 19, 2010 during a flight at Karlsruhe / Baden-Baden airport from a height of about three meters. The pilot and the passenger of the helicopter were uninjured. In spring 2014 there were two more accidents with this helicopter type in connection with uncontrolled turning around the vertical axis.
