India's Defense Research and Development Organization (DRDO) will hold trials of domestically-developed hypersonic combustion ramjet in 2013, reports PTI referring to DRDO director Vijay Kumar Saraswat. According to him, the propulsion system will be capable to work at speeds six times higher than sound speed. Saraswat declined to give any details of the prospective project.

Presently, India is developing a hypersonic missile capable to accelerate up to six Mach numbers. The project is developed by Russian-Indian joint venture BrahMos. The new ammunition will be based on supersonic cruise missile BrahMos already operated by Indian Army. In its turn, BrahMos missile is based on Russian cruise missile Onyx.

Today, active development works on hypersonic vehicles are held by the US, Russia, and Brazil. In particular, American planemaker Boeing jointly with US Air Force is developing hypersonic missile X-51A Waverider accelerating up to six Mach numbers. Besides, Lockheed Martin designs hypersonic vehicle Falcon HTV-2. In its turn, Brazil is developing missile 14-X also supposed to fly at speeds exceeding six Mach numbers.

As was reported late in Aug 2011, Russia's Tactical Missiles Corporation had started research works on a hypersonic missile project. According to the company's chief designer Boris Obnosov, Russian missile will be capable to fly at speeds 12-13 times as high as sound speed.

Besides, it is considered that the Baranov Aircraft Engine Building Institute is also engaged in development of hypersonic vehicle Igla under Project Holod-2. Its deputy director Valentin Solonin told AviaPORT on Apr 22, 2012 that the institute was researching integration of a ramjet and an airframe.

"We research effective compression, combustion, and expansion processes occurring in hypersonic vehicle's propulsion plant, and consider its integration with the airframe. Also, we actively study thermal states of ramjet and airframe. Since the inside temperature makes 2,600-2,700 degrees Celsius and the flight is quite continuous, there are some problems regarding thermal state", Solonin said.
