Turkey is pushing deeper into advanced fighter propulsion with a new turbofan engine designed to support next-gen air platforms.
The engine, known as Güçhan, delivers 42,000 pounds (19,050 kilograms) of thrust, placing it in the same performance bracket as powerplants used in fifth-generation combat aircraft like the American F-35.
It has a diameter of 50 inches (127 centimeters) and moves about 420 pounds (190 kilograms) of air every second.
With a bypass ratio of 0.68:1, the design is optimized for power and speed, reflecting an architecture focused on high-performance operation in demanding conditions.
The Güçhan also incorporates advanced turbine blades manufactured entirely in Turkey, underscoring the country’s expanding domestic aerospace production capabilities.
Once operational, it is expected to power future variants of the KAAN fighter and other autonomous combat aircraft.
Key technical details such as dry thrust output, compressor pressure ratio, and endurance cycle data remain undisclosed.
Stepping Into the Test Phase
Nilüfer Kuzulu, director of the Turkish Ministry of National Defense research and development center, said six prototype units have already been produced, with qualification testing expected to begin later this year.
This suggests the design phase is largely complete, with the program now entering physical validation.
During testing, the engines will undergo thousands of hours of operation at maximum output, exposure to extreme temperatures, and stress tests including scenarios such as bird strikes.
Once ground evaluations are completed, the prototypes will move to flight testing using flying test beds, with full-scale production expected only afterward.
The Güçhan turbofan engine was showcased at SAHA Expo 2026 in Istanbul.
