@porky_kicker @Bleh @Karthi @fire starter @patriots

can somebody else verify this news? eurasiantimes is not reliable. is French Safran really going to help us?

Indian 5th-Gen Aircraft To Be Fast-Tracked As DRDO, French Tech Giant Safran Set To Join Hands




Not sure about this report, may be a counter propoganda for CAG report.

Safran is about to build some facilities in India an entire engine development plan still in discussion??? I don't know

Current plans by Safran.

a new Safran Aircraft Engines facility making turbine parts in Hyderabad.

production startup at the new Safran Electrical & Power electrical wiring plant in Hyderabad.

Safran announced that it was to build a new 13,000-sq.m. plant in Hyderabad in India to make parts for the LEAP engine. The plant will be gradually ramped up, reaching its full production rate in 2023 when it will be delivering over 15,000 parts each year to support the LEAP’s sustained production rate. The plant will ultimately employ some 300 people, all of whom will follow a comprehensive training program. The plant will also be based on Safran’s highest standards for industrial processes and machinery, including real-time monitoring of production parameters and the latest integrated production inspection methods.

or anybody else? do we have anything similar to this chinese mosquito?
and what's the last known status of HAL RUAV

This can be done by ,drones which is used for spraying insecticides ...not a big deal ......but Indian ruav is a different platform.....Indian ruav will be able to deliver 25 kg payload at Siachen...no other platform can be used like this

They are already organizing fashion show of MICA, Derby, Russian junk (as per IAF ) just to appease their masters but shy away by miles when it's come to Indian products.
How Astra is immature despite of clearing all due trials?
Ok.
Lets try to bring your crying to a logical end here. Lets have a look at some of the BVRAAM in use with IAF now.

As you could see in the table below, all the missiles we are using now has decades of development and tweaking behind them before being ordered.

Whenever a new missile like Astra is inducted, a whole lot of user tests and trials are conducted around it and documentation is made. Then this documentation goes around for other pilots to study on and make a strategy around the missile to use in real scenario. Multiple exercises are held with the missile and if needed tweaking on its software or hardware are done. Then only it matures as a system. Astra is just a infant now. IAF has to conduct multiple exercise with it to know about its optimum usage envelope.

So yes. It would need more time for Astra to mature as a system.

thanks for reply, any latest known status regarding HAL RUAV?
It's currently in design-development phase. With proper funding, it's achievable in 1 year. Annual report 2019-20 dosen't mention anything about RUAV.
The broad specs are as follows:
The 200 kg UAV, which is equipped with a twin-blade main rotor and a locally developed petrol engine, is stated to have a range of 200 km, endurance of six hours, and a service ceiling of 6,000 m. The platform, the fuselage of which is 4.2 m long and 1.28 m wide, is reportedly capable of flying at a top speed of 200 km/h and can carry a 40 kg payload.(defenceupdate.in)

For more details on kind of payloads

Please don't give this kind of logics If you have nothing to say then better remain quiet.
According to you, Above said missile were immature when they were inducted?? You mean, relevant countries were fool and inducted immature missiles, some of them even used in War. Meanwhile they has been keep updating our Imported air force about deficiency and tweaking. Once Imported- Cum- Scientist IAF came to know that there no further up-gradating is possible Hence, missile is fully matured and let it Induct. In another words, induct when it become obsolete. Only a IAF's guy can give such logics.

If we go by your logic, Meteor inducted in 2016 and IAF signed the deal in the same year that too without any real war experience. Moreover, IAF has been boasting on Meteor like they themselves gave it birth after profound labor pain

IAF should buy Meteor only after 2026. Sir, why are you not applying your own logic now ?? Why don't we give Meteor to each pilot and ask for optimization and induct only after 2026?? Hain Sir? Why This logic only apply on Astra ??

You want to give Astra to each and every pilot for years of evaluation but Sir, Why IAF didn't bring all these genius pilots on the day of field trials ?? Atleast they should tell under which profile trials need to be done ??

180 nm this is baba hazam jamane ki technology
Its a RISK processor for IoT devices. Fairly good start. Apart from mainstream desktop processors, most of such processors utilize higher lithography nodes only. Most Controllers are made using over 100nm process.
This is not a technology area where you can start directly at level world's major companies are working on.

Please provide source if you have. Couldn't find any credible links in google.
IBM has done test production on 5nm few years back and they were only first one at that time in the whole world. Their team was also working on 3nm wafers but has not succeeded yet.
Its highly unlikely any Indian facility having Lithography machines of even lower than 100nm, forget about 3nm.

Regarding 3 nm technology in iits and iisc: that is true as well as false. The thing to be considered here is that these research institutions have some rudimentary silicon vlsi fabrication technology. Some have electron beam lithograph machine where small features can be made. However those are single devices ( a single diode, or a single mems device etc.) in a small silicon substrate, usually done for educational and research purposes. After fabrication, these single devices are tested for their electrical properties, and if found good results, those results are published in journals.But those devices will never be used by anyone in this world.
Here the point to remember is that it is not a foundry, where batch processing of chips each of which consists of billions of transistors can take place.
In an actual foundry like that of intelligence or TSMC, the node (7nm) is the gate length of each of the billions of transistor of the ic they are fabeicating. Also currently the technology is finfet. We currently have no analogue of these massive foundries in India.
Also same size node from different companies are not actually same in size. Samsung 8nm nodes are smaller and denser then TSMC 7nm node. Intel 10nm nodes again denser and smaller than AMD's 7 nm nodes.
Similarly many so called 5nm test batches are actually larger than new TSMC 7++ nodes.
You can define your node as 3nm based on size of any random part but on global level it could be bigger than other companies 5, 7, 8 or even 10 nm nodes.

Is node defined by actual channel length or gate length?
