Hürjet Tests Transonic Speeds for The Supersonic Phase
Turkish Aerospace (TUSAŞ)’s Hürjet advanced trainer and light combat aircraft prototype has reached a speed of Mach 0.9 at an altitude of 30000 ft. With Hürjet being developed for a maximum speed of Mach 1.4, the test is closer to the supersonic regime than the others, marking another milestone.
The speed specified translates to a speed of 272.8 m/s, considering that the speed of sound at 30000 ft is 303 m/s, lower than sea level at 340 m/s. Mach 0.9 is considered transonic speed in many cases where there is a drastic drag increase until the aircraft reaches the speed of sound. The lower air density at said altitude (2.67 times less than sea level) also causes performance losses. The flight test serves as a verification for Hürjet’s aerodynamic optimisations required to go through the transonic regime and eventually reach the supersonic speeds. Thus, the advanced trainer can be expected to achieve supersonic speeds in the next tests.
