An important development in ISRO’s Air Breathing Propulsion Project (ABPP) occurred on August 28, 2016, which was the successful flight testing of its Scramjet.

This first experimental mission of ISRO’s 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 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 this recent test of Scramjet engines at supersonic conditions. ATV carrying Scramjet engines weighed 3277 kg at lift-off.

Good.

I knew this was on the horizon for them to attempt. I'm glad it went well. This is a wake up call for not just China but for the West as well. Seems that Technology is becoming so cheap. What costs us here in the Western world a small fortune others are able to develop and test for pennies on the dollar.

Good for India.

Beijing you paying attention?

It's not getting a lot cheaper, the technology is getting easier to produce. While this is great news for India and very cool, this test was nothing but engines. Building a non-missile platform that can use said engines is a non-trivial task, for anyone.

I wasn't trying to give the impression it's a trivial matter. Just that through the use of modern computing and everything else that's now available to us it seems that anybody can develop some fairly sophisticated abilities that just a couple of decades ago were out of their reach.

I'm glad India is moving forward.

Now, maybe all the pork programs here in the US will die a quick and horrible death so we can finally utilize all that we've researched and has been billions of our tax dollars spent on start showing us the money.....

They can, to an extent. Getting past that point is where the trouble begins.

Is that Scramjet technology based on Germany's V1 Buzz Bomb from WW2 ?

I guess creating heat/shock resistant material/design is where the problems of further development begin?

I'm no expert but from my understanding it's the reaching a point of trying to force something through the atmosphere without melting or vibrating apart is where the real technical development is needed.

No?

Nazi's developed the "Ramjet" but by technical evolution, the scramjet is the next level of development.

That's where all hypersonic platforms run into trouble. During tests of various US platforms an 8 minute barrier was found. Every flight that successfully ignited the engine self terminated at around the 8 minute mark.

The V-1 used a pulse jet. Different beast and only really usable for missile sized platforms.

I follow but rarely post or comment on this area.

Maybe the small size has a contributing factor? A larger design may add what they need?

I know scaling of the design seems legit but who knows...


"Bigger" maybe just be better?

It may be. A larger platform would have more cooling ability and may stand up better.

i get what you're saying but the scramjet isnt a wake up call for the west, Great Britain first invented the scramjet in the 1960's, played around with it for a bit then realised it wouldnt work, Fast forward 30 years and the USA also discovers the scram jet, Then announces with great furor that they have invented the scramjet, play around with it for a bit then come to the same conclusion as the British and quietly scrap it. The problem with is is it is not feasible to use, It works by accelerating faster and pushing more air through it's engine, The more air goes through the faster it goes, sounds brilliant, but fuel consumption increases exponentially and most flights only last seconds or minutes. It also needs a parasitic takeoff, That means it must be attached to another aircraft for the takeoff and reach a very high speed for the scramjets to start working before it is released. India is about to find out what the UK and USA found out, The scramjet is way to expensive to run, flights last only a few minutes and there is no commercial value in scramjet engines.
