Hi @MastanKhan You're right, I just wish to elaborate on what you said, Failures are a part of R&D venture. It is impossible to design a new product or technology without facing failures. A lot of Pakistanis on this forum are so painfully oblivious to research and general engineering...

Hi It just saddens me the most to see a decent thread going down the drain thanks to trolling. Yes indeed Tejas indeed can be converted into an un-manned aircraft much more easily than developing lets say a fully stealth UCAV. Reasons for that are simple- 1) It would require lesser amount of...

Hi @DESERT FIGHTER There are some factual in-accuracies in your points and I believe I must correct them. 1) In response to your point #B, the development run of Pinaka-2 is already over and it has "demonstrated" a guided range of 75km in field trials. Here is a report directly from GoI- The...

Hi @Blue Marlin Read my comments above very very thoroughly. I've written the time scales necessary. Also do keep it in mind that India has already done a lot of fundamental work necessary for scramjet propulsion. In fact test fired an.engine for 20 seconds. Even after all this India will take...

Hi I'm wondering, like really wondering, do you know any of the things you've written above? I'm talking particularly of scramjet propulsion and the level of development taking place in India and comparison of similar scramjet development all over the world? You're off the mark buddy, there's...

@Taygibay We also have a server with 24 cores,however I was performing the simulations on my own system and it was taking up all the processors and RAM. The reason why AI based controls have not become mainstream is simply because of the computational complexity. In aerospace systems , of we...

Hi @Taygibay That's a very very lofty goal and unfortunately unachievable even for the great US of A. I mean the reason why it is difficult is simply because the combustion inside a hypersonic vehicle takes place super sonically-- I'm specifically talking about scramjet engine. And stabilizing...

@Taygibay In fact I'm working on such a control strategy. I'm expecting my second AIAA paper very soon. It deals with precisely such a control strategy wherein we partially know the system dynamics, yet the control system is expected to track desired trajectory. The major challenge I've faced...

Hi @Taygibay On a slightly different note, this is the indigenous micro turbofan for nirbhay CM that under went high altitude testing at LEH. It performed satisfactorily and produced 400kgf of thrust. Also no matter what fan boys say, the major challenge now in achieving hypersonic speeds is...

hi @Taygibay Yes you're right, the problem of hitting a moving target is inherently more challenging vis a vis hitting a static target.- Fig:1 The above picture deals with the problem of hitting a moving target using PN guidance scheme(not mentioned in the pic above), the PN guidance scheme...

Hi @Taygibay I was about to pass off this thread except for your post and since I believe you have requisite background. Let me shed some light on prospects of Brahmos achieving hypersonics- Unknown to a lot of folks here, DRDL is actually working on both liquid ramjet and scramjet engines. The...

HI! @Pakistani India will first try to accomplish soft landing of rover on moon surface before it can actually go ahead and create a mini biosphere. Soft landing on any extra terrestrial surface is a feat in itself.

Hi Thorough Pro, I think instead of mud slinging that you are so fond of, you should talk based on "credible" scientific facts and evidences. I never denied that Kaveri have had major shortcomings, but those shortcomings taught some major lesson to folks who are my batchmates and are working at...

Whatever that makes you feel good. Peace

@Maarkhoor You can have that opinion. It is perfectly fine to have any opinion as you like, but slowly and gradually you'll see various Indian designed engines replacing foreign ones like trainer jets, Cruise missiles, regional airliners and light fighter jets. Cruise missiles is something that...

Hi wish you had not dragged India into this, but since you have dragged it nontheless, let me clarify couple of things for you- Engine development is perhaps more complicated than developing entire aircraft. There are of course failures and shortcomings in the development process especially if...

I doubt if they would be able to get the satellite back in control.

Hi Shaheen Missile! Yes it is true that Pakistani strategic missiles in general are more road mobile vis-a-vis their Indian counterpart, but that is because Pakistan uses Chinese(which are Russian copies) or Ukrainian TELs. I believe, India should license produce series of MAZ trucks for these...

Indeed they can, because hyperbolics have higher isp compared to similar mass solid rocket. But as the trend is moving towards designing compact missiles, it is "unwise" to design a missile so gigantic and requiring hours of refueling. Besides things get a lot more dangerous in the confines of...

Shaheen! Thats not entirely true. The A-5 uses propellant very similar to A-3. In case you did not know Indian propellant evolved like this- 1) ASLV which gave rise to A-1. 2) A1~A2. 3) A3~A5 4) A4. A-4 is undoubtedly one of the most efficient solid rocket designed by DRDL/ASL for Agni series...
