ATV-01

On 3 March 2010 at 03:00  UTC, ISRO conducted the first test flight of the Advanced Technology vehicle, designated ATV-D01. It weighed at lift-off, and measured long with a diameter of . It carried a passive scramjet engine combustor module as a demonstration of the air-breathing propulsion technology. The ATV successfully reached Mach 6 for seven seconds and maintained a dynamic pressure of .


ATV-02

On 28 August 2016 at 00:30 UTC, the second test flight, designated ATV-D02, was launched from the Satish Dhawan Space Centre. Massing , the rocket carried an active scramjet engine demonstrator. At 55 seconds into the flight, the scramjets ignited at Mach 6 and functioned for about 5 seconds. The flight lasted a total of about 300 seconds and splashed down in the Bay of Bengal approximately from the space centre. Flame was sustained in one engine for 18 seconds and in the other for 14 seconds, producing net positive thrust.
