THK THK-5 / THK-10 / MKEK Models 5

The THK-5 was a twin-engine aircraft developed in Turkey as an air ambulance. First flying in 1945, it was a conventional, low-wing cantilever monoplane of wooden construction throughout. The main units of the tailwheel undercarriage retracted into the wing-mounted engine nacelles and the THK-5 could carry two stretcher cases plus a medical attendant.

This was followed in production by a six-seat utility transport version designated THK-5A and three examples of an improved version of the 5A designated THK-10. A single example of the type was exported, sold to Denmark.

On September 6, 1951 THK-5A serial number 503 sold to Denmark was put into service with registration OY-ACK. The aircraft, which was used as air ambulance under the name TYRKEN (TURK) until logging 961 hours and 20 minutes. In 1960 it was resold and used by air taxi companies. On 18 November 1961 the airplane suffered a landing accident and was withdrawn to a children’s park in Lagunen. The wreck was eventually scrapped.

THK-10

In total 13 were built.

When THK was taken over by MKEK, this was one of the designs selected for further work. However, although the designation MKEK-5 was allocated, nothing further came of this.

THK THK-2 / MKEK 2

In 1936, Turkey bought 36 Polish R.24E fighter, simultaneously launching construction of an aircraft factory in Etimesgut near Ankara. The director of the factory became a Pole Jeri Vedrichovsky. The first aircraft built with the help of Polish engineers was the TNK-2 training monoplane. Stanislav Rogalsky, Jeri Telsiye and Leszek Duleba took part in its development. The design team took the RWD-10 as a basis, with several modifications. Preserving the same wooden construction of the Polish prototype. The single cockpit made completely closed. The English DH “Gipsy Major” motor, was also installed on Miles M.14 training aircraft built under licence.

The design and construction of the aircraft took place in 1943-1944 at the Turkish Aviation League (Turk Hava Kurumu).

Designed for aerobatic training, the first prototype of the TNK-2 was airborne in mid-1944. The second prototype took to the air in 1945, showing better performance than the first and the British Miles M.14.

Serial production amounted to only four aircraft that served in the Turkish Air Force until the mid-1950s. In 1952, after changing the name of the company, these aircraft were renamed MKEK-2.
