AMCA is a 25-ton, proper fifth-generation platform that has undergone 20 iterations to finalize the aircraft’s shaping and achieve an optimal stealth geometry. The project involves more than 100 design centers. 🧵

📷@Kuntal__biswas It is the result of institutional knowledge developed from Tejas program. The fighter will be capable of doing many types of missions including air superiority, ground strikes, SEAD.

The $250 million was among the best-spent funds on any program in the country, and it is the primary reason why any international engine house is offering to co-develop a 5th gen engine (T/W > 10). We developed DMS3 back in 2002, then DMS4, DMRL learned from HAL Koraput and eventually out did the Russians

The blades were more advanced than whatever HAL was making for AL31

In 1972, DRDL launched a secret project with an objective to reverse engineer SA-2 Surface to air missiles, acquired in the 1960s from USSR in seven years

📷 @VinodDX9 The name was given by DCAS Shivdev Singh, given V.S. Narayanan(director of DRDL) used to behave like the devil at work.

The 1974 Test device was little over four feet in diameter, and weighted around 1.4 tons. The Plutonium generated by Cirus reactor's fuel rods was used to make the first bomb

In 1970 the main plutonium extraction plant suffered a leak and was shut down leading to shortage of Pu Engineers first thought they could restart the plant within a year, but by late 1972 they told Ramanna it would take about another year

With MIDHANI set up in Hyderabad, India indigenized key titanium alloys for aerospace in forms like billets, rods, plates & sheets.

It produces up to 4-ton billets & covers all 3 classes: α, α+β & β. MIDHANI supports both Western & Russian engine alloy needs. Ti-6Al-4V, a key titanium alloy for aerospace, needs high structural integrity & strict ultrasonic inspectability (e.g. 1.2 mm FBH). The Initial Hot Processing Schedule with β and α+β forging plus 700°C annealing gave poor clarity & coarse structure.

PFBR is not the first breeder reactor in the country, India has been operating Fast Breeder Test Reactor since 1985, a 40 MWt research reactor to provide the experience for follow up 500 MWe PFBR. In a moderator reactor, the neutrons have very high energy and they are immediately slowed down by the moderator (ie heavy water), while in fast reactor neutrons are not moderated

Complete Info about Kaveri Engine (1/2)🧵 ➡️Kaveri, or GTX-35VS, is an afterburning turbofan engine.
➡️GOI sanctioned the project in 1989 with a budget of ₹382.21 crore.
➡️GTRE had already developed an engine called GTX37-14U, which was an IDDM turbojet engine.

Complete Info about Kaveri Engine 🧵(2/2)
➡️DMRL also showcased their "isothermal forging technology" with their 2000 MT isothermal forge press.
➡️They have supplied 200 HPC discs to HAL. ➡️We have done an incredible amount of work on composites, which we demonstrated with HSTDV.

Little Story about Heavy Press🧵
➡️Nazi Germany had the largest heavy die forging presses in WW2
➡️ During the aluminum shortage, they used Mg instead to make aero components
➡️ Mg is brittle & bending it causes cracks
➡️ Germany got around this flaw by using heavy presses ➡️In 1944, the US started Heavy Press Program after being impressed by German manufacturing capability.
➡️In 1946, an 18,000-ton press, built by Mesta Machinery, was completed.
