TAI Hurkus is a primary and basic trainer aircraft designed and manufactured by Turkish Aerospace Industries (TAI). It is a two-seat, single-engine turboprop aircraft being developed from the KAI KT-1 trainer. It is being built principally to meet the requirements of the Turkish Air Force (TAF). The aircraft will be used to execute basic pilot training, instrument flying, navigation training, and weapons and formation training missions.
KT-1 Woongbi: Details
The Hurkus will also be exported as a civilian and military flight trainer aircraft. The first aircraft was rolled out in June 2012. Its maiden flight, which was expected to take place in 2009, was first delayed until November 2012 and then further until mid-2013. It was finally held in August 2013 and three more tests were performed in September 2013. Hurkus flew at an altitude of 10,200ft during its fourth flight.
Hurkus training aircraft design
Hurkus has been designed to execute its missions day or night. It is being built adhering to the EASA CS 23 standards. In December 2006, the Secretariat for Defence Industries (SSM) approved the eight-month conceptual design of the Hurkus. The critical design review of the aircraft was completed in April 2009.
The aircraft has been designed to be fully operational in civil and military pilot training bases all over the world. Hurkus is equipped with a Pratt & Whitney Canada engine that can produce 1,600hp of output power.

Development of the Hurkus aircraft
The development programme of the Hurkus began in March 2006 as part of the contract signed between the SSM and TAI. The programme includes the development of two aircraft variants, namely Hurkus-A basic trainer and Hurkus-B advanced trainer. Four aircraft will be designed, built, examined, verified and certified by TAI under the programme.
The aircraft was named after Turkey’s first aviator, Vecihi Hurkus. It was designated such during the eighth International Defence Industry Fair held in Ankara, Turkey. The indigenous design prototype of Hurkus was showcased at the 47th International Paris Air Show in June 2007.
Microtecnica (now part of Goodrich) was awarded a contract by TAI in April 2010 to supply the environmental control system (ECS) for the Hurkus trainer aircraft. The ECS is equipped with three major subsystems including bleed air, temperature control and cooling. The system uses air discharged from the engine to pressurise, ventilate and heat the cabin. In contrast, cooling is rendered by a separate vapour cycle compressor. Work on the first prototype of the ECS was concluded at the end of 2010. The European Aviation Safety Agency (EASA) certified the Hurkus aircraft design in July 2012.
Hurkus basic trainer/light attack aircraft conducted its first missile test: Here
The Turkish Aerospace Industries (TAI) Hurkus basic trainer/light attack aircraft conducted its first firing test with a missile on 7 March, launching a Roketsan L-UMTAS laser-guided long-range air-to-surface anti-tank missile.
The L-UMTAS missile, fired from a Hurkus at the Firing Test and Evaluation Group Command test range near the central Anatolian town of Konya-Karapinar, hit its target successfully, Turkish defence minister Fikri Isik stated on 8 April in a message posted on Twitter.
- Basic version which has been certified with EASA according to CS-23 requirements. It is intended for the civilian market
- Advanced version with integrated avionics (including HUD, MFDs, and Mission Computer). Cockpit avionics layout is similar to F-16 and F-35 fighters. The Turkish Army is considering an order for 15 aircraft.
Hürkuş-C – Image @afwing.com
- An armed version for the close air support role will have a maximum weapons load of 3,300lb (1,500kg) and also carry a forward-looking infrared (FLIR) sensor. As the Hürkuş will be capable of operating from unprepared runways, it could also attract export orders, TAI believes. The Turkish Army has expressed interest in the Hürkuş C to provide support for its attack helicopters.

- TAI plans to offer another version of the Hürkuş to support the Turkish Coast Guard’s maritime patrol operations. The aircraft’s rear seat would be occupied by an operator for a FLIR sensor using an ASELSAN FLIR system.

BDU33 and MK106 training ordinance
BDU33 training ordinance
Practice ordnance includes 25-pound BDU-33 bombs having a spotting charge that releases a cloud of smoke on impact. The BDU-33 is used to simulate the MK 82 in low drag configuration. The munitions to be loaded onto aircraft are brought to the flightline on a trailer. The BDU-33 bombs are lifted out of a metal cage on a trailer and are locked in place underneath the aircraft. The BDU-33 bombs are lifted out of a cage on the trailer and carried to the aircraft 20 feet away. BDU-33 munitions are loaded onto TERs (Triple Ejector Racks) and SUUs (Suspension Units). The BDU-33 is pushed against a spring loaded catch and locked into place. The unloading of the BDU-33 from the aircraft involves loosening the bolts and releasing the spring. The BDU-33 is carried back to the trailer. Source fas.org
