GÖKBEY MULTIROLE UTILITY HELICOPTER

GÖKBEY Multirole Helicopter is a new generation, twin engine, 6 ton class helicopter developed in response to the growing market demand for higher mission flexibility in this class.

GÖKBEY is designed and optimized to meet and exceed the multi-mission requirements for hot & high geographical environments and for adverse weather conditions. The aircraft incorporates several new technology features to provide the highest levels of safety and operational benefits for operators.

Within the scope of the contract signed between Turkish Aerospace Industries, Inc. and Undersecretariat for Defence Industries (SSM) in 2013, GÖKBEY Multirole Helicopter is being developed for both domestic and international markets.

The platform has a five-bladed main rotor and a four-bladed tail rotor to minimize vibration and noise. Both main and tail rotor hubs are fully-articulated with elastomeric bearings. Both rotor systems are driven by a transmission system which consists of the three-stage main gear box having the capability of operation for 30 minutes in the event of loss of lubrication. Within the scope of the program, critical systems such as transmission system, rotor system and landing gears as well as aerostructures are designed from scratch in Turkish Aerospace.

GÖKBEY  has state-of-the art ASELSAN avionics with glass cockpit having two wide touchscreen (8x20 inches) Integrated Mission Displays and two touch screen (8x10 inches) data entry Touch Command Control Unit. A 4-axis dual redundant automatic flight control system is developed to provide superior performance and handling quality.

The cockpit provides a comfortable and high visibility environment for both pilots. GÖKBEY cabin is designed for comfortable seating for 12 passengers. The extensive cabin space can be configured to meet the requirements of multi-purpose operations such as cargo, VIP transportation, ambulance, off-shore and search & rescue operations. The geometry of the helicopter is optimized for maximum aerodynamic performance with retractable landing gears hence providing an efficient fuel consumption leading to better range and endurance.

GÖKBEY Multirole Helicopter incorporates two LHTEC (a Rolls Royce & Honeywell Partnership) CTS800 turboshaft engines, 1373 shp each, enabling the aircraft to perform in hot & high environments and perform safely in one engine loss condition for Category-A certification. GÖKBEY is designed for IFR and VFR single pilot operations, night operations and flight in known icing conditions.

Civil certification process of the Helicopter is ongoing with Turkish Directorate General of Civil Aviation which is planned to be followed by EASA (European Aviation Safety Authority) certification.

The first prototype aircraft has successfully performed its first flight on 6th of September 2018 at its facilities Ankara, Turkey. Serial production is expected to start after 2021.
