ANKARA, Turkey — Turkey’s defense procurement authorities have given pace to their work to select an engine know-how supplier that will be the backbone of the TF-X, an indigenous Turkish fighter jet in the making.
“We may not hold onto our original target of officially announcing a technology partner (for the engine) in January, but we will come very close to it,” said a senior procurement official familiar with the program.
At the end of October, Turkey’s top procurement official, Ismail Demir, said his office would announce its decision on the TF-X engine in January 2018.
An official from Turkish Aerospace Industries, the prime local contractor for the TF-X program, said talks with a number of potential technology suppliers and their local partners have recently matured enough to give decision-makers a clear picture.
“The idea is to rely on foreign technology in order to build, in the longer term, an indigenous engine that will power the TF-X,” the TAI official said. “I think we are close to an understanding.”
The TF-X program is run by the country’s procurement agency, the Undersecretariat for Defense Industries. But the decision on the engine will be made by the ultimate panel that oversees top procurement decisions ― the Defense Industry Executive Committee, which is chaired by Prime Minister Binali Yildirim.
In October 2016, engine-maker Rolls-Royce offered a joint production partnership to Turkey with a view to powering planned Turkish platforms and potential sales to third parties. The British company’s proposal involved a production unit in Turkey to manufacture engines for the TF-X, as well as for helicopters, tanks and missiles.
A year before that, in October 2015 a memorandum of understanding had been signed between Turkey and Rolls-Royce for technological know-how and a production unit. Under the plan, Rolls-Royce will launch an advanced manufacturing and technology center in Turkey ― the company’s eighth such unit worldwide.

U.S. engine-maker Pratt & Whitney is also in the picture. In 2014, the company inaugurated its Turkish partnership with local aviation company Kale to produce critical engine parts for the multinational new-generation F-35 fighter jet. Kale Pratt & Whitney, the joint venture, will manufacture the parts of the F-135, the engine for the F-35.
Meanwhile, Tusas Engine Industries, a government-controlled engine maker and TAI’s sister company, is currently working to refine a 20-year road map for the design, development and manufacturing of a local aircraft engine, also with the aim of powering the TF-X.
Industry sources say the engine selection is the most critical phase in the TF-X program.
“All other design work will depend on the engine to be selected,” the TAI official said. “Once we have decided on the engine, the rest of the program will automatically gain pace.”

Turkey chooses jet engine variant for indigenous trainer

ANKARA, Turkey — Turkey’s aerospace powerhouse and procurement authorities have agreed on a program to launch a jet-engine version of the country’s first indigenous basic trainer aircraft, the Hurkus.
The turboprop Hurkus has been developed by Turkish Aerospace Industries, which earlier this year set out for the Hurjet, the Hurkus’ jet version.
TAI officials said a decision by the board of directors in August paved the way for the Hurjet’s development program. They estimate a six-month “preliminary architecture phase” for the start of the program.
One TAI official said it was unclear if the Hurjet will have a single engine or a twin engine. “If we decide to [go] for the twin-engine option, we will need to redesign the Hurkus for the jet version,” he said.
The Hurjet is expected to make its maiden flight in 2022. It will have a maximum speed of Mach 1.2 and can fly at a maximum altitude of 45,000 feet. The Hurjet will have a maximum payload of 3,000 kilograms. The Hurjet will replace the aging T-38 aircraft in Turkey’s inventory.
TAI officials say they also want to develop an armed version of the Hurjet for both the Turkish and export markets.
TAI already is working on an armed version of the Hurkus. Under the plan, the company will develop and manufacture 12 Hurkus-C armed trainers with a follow-on option to deliver 12 more.
According to the contract signed between TAI and the country’s procurement office, the Undersecretariat for Defense Industries, or SSM, the program for the armed trainers will involve maximum-possible locally developed software and hardware, including their design and integration.

Turkish officials have successfully tested the Hurkus-C equipped with L-UMTAS, a laser-guided, long-range, anti-tank missile. L-UMTAS was developed by the state-controlled missile-maker Roketsan primarily to operate from attack helicopters. In 2016, the system was qualified and integrated into the T-129, a Turkish attack helicopter built under license from AgustaWestland.
The aircraft also features other locally developed ammunition including CIRIT, TEBER, HGK and LGK. In addition, it can use INS/GPS-guided bombs, conventional bombs, non-guided rockets and machine guns.
The armed Hurkus features armored body parts, a self-protection system, a data link, laser tacking, an electro-optical and infrared pod, an external fuel tank, and advanced avionics, according to TAI. With its 1,500-kilogram payload that can be utilized through seven external hard points, the Hurkus-C will perform light-attack and armed-reconnaissance missions.
TAI expects the armed Hurkus to be widely used in Turkey’s increasing counterinsurgency fight against pro-Kurdish and Islamic militants both inside Turkey and across its border with Syria and Iraq.
TAI’s engineers began to design the Hurkus in 2004. For the Hurkus program, TAI signed two contracts with SSM: one for prototype development and the other for serial production. Under a June 2014 serial production contract, TAI will deliver 15 aircraft with a follow-on option for 40 more.
The Hurkus platform features a single Pratt & Whitney Canada PT6A-68 turboprop engine that comes with a power rating of 1,600 shaft horsepower and a maximum speed of 574 kph. TAI’s sister company, Tusas Engine Industries, which specializes in engines, is locally developing a turboshaft engine to replace the Pratt & Whitney Canada engine.
