Advanced Technology Vehicle

The Advanced Technology Vehicle is a modified Indian sounding rocket developed by the Indian Space Research Organisation (ISRO). It is based on the Rohini-560 rocket. The ATV program was created to test the development of a native dual-mode air-breathing scramjet engine. As of 2016, ISRO has flown two test missions.

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 3,000 kilograms (6,600 lb) at lift-off, and measured 9.10 metres (29.9 ft) long with a diameter of 0.56 metres (1.8 ft). 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 80 kilopascals (12 psi).[1][3]

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 3,277 kilograms (7,225 lb), the rocket carried an active scramjet engine demonstrator. At 55 seconds into the flight, the scramjets ignited at Mach 6 and functioned for five seconds. The flight lasted a total of about 300 seconds and splashed down in the Bay of Bengal approximately 320 kilometres (200 mi) from the space centre.[2]

Combustion was sustained in one engine for 18 seconds and in the other for 14 seconds,[4] producing net positive thrust.[5]
