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! Folks! Randomly sifting through internet after ASAT tests, I ran into these pics. This missile seems a bit bigger for Agni-1*. It is also not the ASAT weapon that was tested recently- kindly compare both the stages and it'll become apparent that it is very different from the ASAT that was...

These are perhaps the first ever pics available in public domain via Google Earth, wherein one can see the Arihant parked besides Chakra. As one can see, Arihant is slightly longer than the Chakra, perhaps as much as 10m longer. However the beam seems smaller. In the pics one can easily identify...

Hi! DRDO's annual report has just been published and it contains wealth of information on various systems except strategic ones. For instance DRDO's report has this to say about Nirbhay and indigenous turbofan: Analyzing, open source report on Nirbhay we see that Nirbhay has a potential to...

Hi I wish to highlight some of the broad areas where DRDO is currently working on. Some of these areas have seen profound success and others not so much. Either way I will put forward some of the systems DRDO is working on. Radars: This is one of those areas where DRDO have had substantial...

Hi everyone! These are some of the developments and my own thoughts based on my interaction and experience with radars. Some of the major modes realized so far in uttam AESA radars are- 1)Air-Air mode (a) Target acquisition mode (b) Countermeasure support mode (c) Performance monitoring (d)...

This video is from a recent seminar held at Aero India-2017 bangalore. Notice the kind of R&D activity going on in india in the field of solid rockets/dual pulse motors/throtleable ramjets etc etc. Interestingly DRDL faced severe combustion instability issues in the design of their dual-pulse...

Quad-Packed HELINA ATGM for LCH. This photograph has been taken from DRDO's annual report. Plans are definitely in place to have HELINA in quad pack configuration on board LCH. So,all in all,LCH can field 8 HELINA ATGMs along with 4 Mistral A2A missile. This combination makes it super deadly...

It is so nice to see that ISRO is seriously working on semi-cryogenic engine for GSLV MK-3. 1)According to Dr Sivan(LPSC),semi cryogenic engine will simply boost the payload carrying capacity from 4-5 tonnes class(to GTO) to 6-7 tonnes class--or an improvement of 2-tonnes straight! With...

NEW DELHI: Leading the pack of the country’s premier educational institutes in terms of patents, the Indian Institute of Technology - Madras (IIT-M) has filed applications for, and secured, the most number of patents among IITs. According to the Human Resource Development Ministry, IIT Madras...

A group of engineers at the Indian Institute of Technology Madras (IIT-M) has cracked the elusive secret code of thermoacoustic instability, a problem that gas turbine and aerospace industry has been grappling with for decades, incurring losses to the tune of $1 billion annually. The team has...

If true,then it is perhaps the most significant news of the year! It seems india today test fired B05 or K-15 short range SLBM from arihant SSBN.This was the first test of K15 from ARIHANT. K-4 however will replace K-15 in near future. LIVEFIST: BREAKING: Arihant Fires Unarmed Missile...

Hi folks! This is my first thread and i will be writing on TERCOM guidance in certain depth.My analysis is NOT rigorous and doesnt entail signal processing.I can deal with it later in my subsequent threads if readers feel it necessary So what is TERCOM?Well the first thought that comes to our...

Here is my little analysis, as to why FBRs/TBRs are better that rivals for PWRS/PHWR 1) A breeder reactor is designed to create more fissile material (nuclear fuel) than it consumes. Depending on the Breeding Ratio of a reactor, it can produce new fuel at a greater or lesser rate. The...
