2016年8月28日,印度空间研究组织(ISRO)于当地时间早上6点在Satish Dhawan航天中心成功完成了首次超燃冲压发动机带飞点火试验。试验采用了ATV探空火箭作为带飞平台,两具氢燃料超燃冲压发动机被捆绑在第二级火箭的侧面。整个试飞系统起飞总重约3277千克,起飞后两级助推器依次点火加速,在达到高度20千米、速度马赫数6的预定条件后,超燃冲压发动机点火启动,并持续工作5秒。整个飞行全程约300秒,探空火箭将溅落在距离发射点320千米外的地方。试验全过程与预定计划完全吻合,成功验证了超声速点火、稳定燃烧、进气道结构、燃油喷注系统等关键技术。


The first experimental mission of ISRO’s Scramjet Engine towards the realisation of an Air Breathing Propulsion System was successfully conducted today (August 28, 2016) 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. Today’s test was the maiden short duration experimental test of ISRO’s Scramjet engine with a hypersonic flight at Mach 6. ISRO’s Advanced Technology Vehicle (ATV), which is an advanced sounding rocket, was the solid rocket booster used for today’s 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. Today’s 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 Scramjet Engine. The successful technology demonstration of air-breathing Scramjet engines in flight by ISRO today is a modest yet important milestone in its endeavour to design and develop advanced air breathing engines including engines for ISRO’s future space transportation system.
