DocM Posted August 29, 2016 Share Posted August 29, 2016 Besides a hypersonic cruise missile, this may be destined for the spaceplane they tested a few months back. BANGALORE, India (ISRO PR) An important development in ISROs Air Breathing Propulsion Project (ABPP) occurred on August 28, 2016, which was the successful flight testing of its Scramjet. This first experimental mission of ISROs Scramjet Engine towards the realisation of an Air Breathing Propulsion System was successfully conducted from Satish Dhawan Space Centre SHAR, Sriharikota. After a smooth countdown of 12 hours, the solid rocket booster carrying the Scramjet Engines lifted off at 0600 hrs (6:00 am) IST. The important flight events, namely, burn out of booster rocket stage, ignition of second stage solid rocket, functioning of Scramjet engines for 5 seconds followed by burn out of the second stage took place exactly as planned. After a flight of about 300 seconds, the vehicle touched down in the Bay of Bengal, approximately 320 km from Sriharikota. The vehicle was successfully tracked during its flight from the ground stations at Sriharikota. With this flight, critical technologies such as ignition of air breathing engines at supersonic speed, holding the flame at supersonic speed, air intake mechanism and fuel injection systems have been successfully demonstrated. The Scramjet engine designed by ISRO uses Hydrogen as fuel and the Oxygen from the atmospheric air as the oxidiser. The August 28 test was the maiden short duration experimental test of ISROs Scramjet engine with a hypersonic flight at Mach 6. ISROs Advanced Technology Vehicle (ATV), which is an advanced sounding rocket, was the solid rocket booster used for this recent test of Scramjet engines at supersonic conditions. ATV carrying Scramjet engines weighed 3277 kg at lift-off. ATV is a two stage spin stabilised launcher with identical solid motors (based on Rohini RH560 sounding rocket) as the first as well as the second stage (booster and sustainer). The twin Scramjet engines were mounted on the back of the second stage. Once the second stage reached the desired conditions for engine Start-up, necessary actions were initiated to ignite the Scramjet engines and they functioned for about 5 seconds. ATV flight operations were based on a pre-programmed sequence. Some of the technological challenges handled by ISRO during the development of Scramjet engine include the design and development of Hypersonic engine air intake, the supersonic combustor, development of materials withstanding very high temperatures, computational tools to simulate hypersonic flow, ensuring performance and operability of the engine across a wide range of flight speeds, proper thermal management and ground testing of the engines. India is the fourth country to demonstrate the flight testing of a Scramjet Engine. Link to comment Share on other sites More sharing options...

Draggendrop Veteran Posted August 30, 2016 Veteran Share Posted August 30, 2016 This engine is for the RLV-TD tested last month... RLV-TD Winged Space Vehicle – Photo: ISRO Quote In a statement, ISRO describes Sunday’s test as “a modest yet important milestone in its endeavor to design and develop advanced air breathing engines including engines for ISRO’s future space transportation system.” Development on India’s Scramjet will continue to achieve a sustainable operation of the engine in the hypersonic flight regime before its introduction on the RLV-TD space plane. Flying the RLV-TD with a Scramjet will be the culmination of the current test program, but is still several years in the future. The test would see the RLV-TD blasting off atop a rocket to accelerate to a speed sufficient for the Scramjet to begin operation ahead of a guided return to a runway that is being established at the Satish Dhawan Space Center. Making slow but continuous progress, India aims to debut its operational reusable launch vehicle in around 15 years time. The operational version of the vehicle would be at least five times the size of the RLV-TD testbed and feature a combination of air-breathing propulsion and conventional rockets – enabling the first stage to complete a fly-back to a runway and the second stage to return from orbit after the completion of its mission. more at the link....
