'''Reusable Launch Vehicle–Technology Demonstration Programme''' is a series of [[technology demonstration]] missions that has been conceived by
For this purpose, a winged reusable launch vehicle technology demonstrator ('''RLV-TD''') has been configured. The RLV-TD acted as a flying test bed to evaluate various technologies like powered cruise flight, [[hypersonic flight]], and autonomous landing using air-breathing propulsion. Application of these technologies would bring down the launch cost by a factor of 10.<ref name="Presentation">{{cite web |url=http://www.livemint.com/Politics/T25O2kOeVcOL2vRfml0baK/Isros-small-steps-towards-developing-its-own-reusable-rocke.html |title=Tuesday, December 22, Isro's small steps towards developing its own reusable rocket [Reusable Launch Vehicle (RLV)] program |work=LIVE MINT, IN |date=2015 |access-date=2015-12-23 |archive-date=2016-05-26 |archive-url=https://web.archive.org/web/20160526125339/http://www.livemint.com/Politics/T25O2kOeVcOL2vRfml0baK/Isros-small-steps-towards-developing-its-own-reusable-rocke.html |url-status=live }}</ref> This project has no connection with the [[Avatar (spacecraft)|Avatar]] spaceplane concept by India's [[Defence Research and Development Organisation]].<ref name="Avatar is DRDO">{{cite web |url=http://dos.gov.in/sites/default/files/USQ251.pdf |title=Government of India Department of Space |date=March 14, 2012 |access-date=2016-04-27 |quote=Feasibility study of project "AVATAR)" has been done by a group of scientists in DRDO.
