Hi @casual There are two hypersonic wind tunnels in India as far as I know. Both of them can generate scenarios upwards of 5 Machs (1) Hypersonic wind tunnel at IISc Bangalore (the desire to establish a hypersonic wind tunnel at IISc Bangalore dates back to early 1970s, however due to...

I am not the one who ever said that Pakistan has designed and manufactured a micro turbofan. It was you (based on perhaps def expo interactions). So the burden of responsibility squarely lies on the person making the claim with concrete evidences much like how certain other members do Actually...

Hi @Bratva Lets get down to deconstructing what you wrote shall we? And for a second lets be civilized. If there is indeed a Pakistani designed micro turbine as you have pointed out, dont you think there would be at least: (1) One test firing on the ground-based test facility? (2) Some related...

@Chak Bamu I edited the last para.

Hi @Chak Bamu , There are two facets of any control design: (1) Understanding the dynamics and (2) Understanding the control theory. First and foremost, one must understand the dynamics of the system. This could be achieved by going through any decent book on flight dynamics. A full nonlinear 6...

How is cloud relevant to India's research effort in control/flight dynamics? Since when did politicians start designing flight controls? Let politicians do their thing and for now focus on the primary topic of this thread.

Kindly add relevant posts with thorough background investigation.

India’s growing research potential in control theory and implications for flight control India has produced many giants in the field of control theory who have contributed immensely in various branches of this wonderful discipline. Three names that immediately come to my mind are: (1)...

Hi! Dont waste your time explaining it to people who lack the ability to grasp technical stuff. The other guy you've been explaining to, I hate to say, is downright . I mean he clearly DOES NOT understand and it is plain foolishness to waste your time and efforts on someone who does not...

This is really ridiculous. I mean no credible link to support the claim. Brahmos is a 3t missile, they adapted an air to ground version that still weighs 2.5t! It will be very difficult to convert this A2G stand off weapon to long range A2A BVR. First off they will have to bring it within 1t...

Based on my interaction with some of the CVRDE folks, they said that there's already a project going on to reduce the weight of Arjun Mk2 by at least 3.5t using HN steel and some optimization. There is one prototype getting ready that will have an all out weight less than 65t. I only wish they...

Hi @HAIDER Your assessment is not far from truth. I must add though, that, both India and China benefited from Gerald Bull's work. Most of Chinese 155mm guns are direct spin offs of GC-45/GHN-45. You see, Bharat Forge is one of the biggest forging companies in not only India but in the whole...

Hi @JamD, convergence of an algorithm and Lyapunov stability of that algorithm are two very different things. Especially in an on-policy setting. That is simply because it is very new and not mature. If you look at RL for continuous time nonlinear systems you'd realise that the whole field...

Hi @JamD , This is something that piqued my interest and since I work on reinforcement learning/integral reinforcement learning (RL/IRL) I can shed some light on this. What you have written above is partially true. I will elaborate where it is wrong. You can have a look at my papers on arxiv for...

In my opinion, the primary challenge India faces is that of bureaucracy. What corruption is to Pakistan, Bureaucracy is to India. Over the years, India does have developed some core competencies in various aspects of aerospace research like aerodynamic layout design and refinement via a lot of...

Hi @denel This is one of the most complex missions ISRO has planned/undertaken as it involves soft landing and rover. It involves not only injecting the orbiter in correct moon orbit, but also landing the rover softly on the moon surface. The complexity of this mission will only be surpassed by...

Actually it doesn't work like that. There are areas where India is closely trailing EU in technology and then there are those where they are visibly ahead of India. Since we are specifically talking about hypersonics , let's just confine ourselves to the realm of hypersonic alone and not get...

Contrary to what a lot of you think hypersonics is a very very sensitive technology and no one shares it. It is much more sensitive than nukes now.

Check it now

@The Deterrent You are actually quite right, one can obtain a lot of information over the years from GE- provided one knows where to look. As for India's doctrine, it is a work in progress. You cant really have a sound survivable arsenal if you lack various sensors- radars are just part of the...
