From TAI MAG 135:
Two Major Developments in the HÜRJET Project
The Jet Trainer Aircraft HÜRJET completed its 27th flight in October, successfully passing several rigorous
tests. After spending 18 hours in the air, the aircraft's testing procedures continue. The design phase of the
HÜRJET project concluded after the Critical Design Review Meeting, held on two separate days.
The Jet Trainer Aircraft HÜRJET took to the skies for the 27th
time in October. During this flight, the aircraft, which had accumulated a total of 18 hours in the air until October 11, 2023,
underwent calibration of the air data system and model verifications. For the execution of high-speed tests, the landing gear
was gathered, and the engine power was increased to Max A/B
level.
With the engine power at Max A/B, the aircraft's propulsion
system generated 50 percent more thrust, enabling speeds of
up to 0.6 times the speed of sound. The speed envelope of
HÜRJET, which aims to surpass the speed of sound, continues
to expand. In the following period, tests beyond the speed of
sound will be conducted with other HÜRJET prototypes.
Missed approach tests were conducted alongside formation flights. With these tests, the operational evaluations of
HÜRJET, designed as a jet trainer aircraft, for the use of pilots
and pilot candidates were completed. The missed approach
tests, which aimed at assessing responses to potential emergency scenarios encountered during flight training, were conducted successfully.
In the upcoming phase, HÜRJET's systems will undergo development and verification tests, aimed at expanding its current
limitations. As these limitations are extended, envelope expansion tests will be conducted, allowing for higher speeds and
altitudes. This will enable HÜRJET to perform more aggressive
maneuvers in the sky.
On September 2, 2023, HÜRJET performed a formation flight
with six Turkish Stars aircraft showcasing its success in aerobatic
flights, in addition to its basic trainer aircraft capabilities validated in the conducted tests.
Design phase concluded
Within the scope of the HÜRJET project, a Critical Design Review Meeting was held in two separate sessions with the participation of the Defence Industry Agency (SSB) Directorate General of Military Factories (AFGM) and our company.
The meetings were attended by Air Force Major General and
Pilot Kadircan Kottaş; Air Force Brigadier General and Pilot Cihangir Yay; Prof. Atilla Doğan, Vice President of Aircraft at Turkish Aerospace; Mehmet Eldem, Vice President of Flight Operations; Ömer Faruk Türkmen, Vice President of Quality and
Certification; and Abdurrahman Şeref Can, Head of the Turkish
Fighter KAAN Department at the Defence Industry Agency.
At the first session held on October 3-4, 2023, presentations
were made on various aircraft systems, accompanied by discussions where participants shared their views.
During the second session on November 20-21, 2023, the project's current status was evaluated. Subsequently, following the
presentations and the gathering of opinions, the design phase
activities concluded.
