The '''Advanced Technology Vehicle''' is a modified Indian [[sounding rocket]] developed by the [[Indian Space Research Organisation]] (ISRO). It is based on the [[Rohini (rocket family)|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 {{convert|3000|kg|lb}} at lift-off, and measured {{convert|9.10|m|ft}} long with a diameter of {{convert|0.56|m|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 {{convert|80|kPa}}.<ref name="thewire" /><ref name="isro1">{{cite web |url=http://www.isro.gov.in/update/03-mar-2010/successful-flight-testing-of-advanced-sounding-rocket |title=Successful flight testing of advanced sounding rocket |publisher=Indian Space Research Organisation |date=3 March 2010 |access-date=10 September 2016}}</ref>

==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 {{convert|3277|kg|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 {{convert|320|km|mi}} from the space centre.<ref name="isro20160828" />

Combustion was sustained in one engine for 18 seconds and in the other for 14 seconds,<ref>{{cite AV media |url=https://www.youtube.com/watch?v=G4S6S7nj4xU&t=2605 |archive-url=https://ghostarchive.org/varchive/youtube/20211221/G4S6S7nj4xU |archive-date=2021-12-21 |url-status=live|title=EML by Dr A S Kiran Kumar Chairman ISRO |series=Dr APJ Abdul Kalam Memorial Lecture |publisher=Extra Mural Lectures IIT Madras |work=YouTube.com |access-date=5 November 2016}}{{cbignore}}</ref> producing net positive thrust.<ref>{{cite AV media |url=https://www.youtube.com/watch?v=ftJDivTCfQg&t=936 |archive-url=https://ghostarchive.org/varchive/youtube/20211221/ftJDivTCfQg |archive-date=2021-12-21 |url-status=live|title=Heads of Agencies Plenary at the 67th International Astronautical Congress |publisher=SpaceRef |work=YouTube.com |access-date=5 November 2016}}{{cbignore}}</ref>
