TBC by EE beam technology. The result of this is very encouraging.

This fan give pressure ratio of 5:1, while being distortion resistant. For a pressure ratio of 30:1 we have to improve all LP and HP stages.

UK is the most unreliable partner as defence supplier. Without tot and indigenous manufacturing capability attained as a result of tot you can not believe UK . Perhaps so gov keeps all ongoing projects or stating near future projects as low profile . But sometime they deliver also as they give...

I am giving you reply point by point . 1. I am stuck with scb and blisk because these are the tech where India struggling . However blisk , wide cord blade and scb are present in hal htfe 40 , but these new tech despite being in India not reportedly goes in Kaveri as Kaveri is noisy at ab and...

Your welcome . I am waiting for your reply . All my information based on media news , defence forum , and chatting with few people claimed that they have inside knowledge . You are most welcome . Two most revolutionary programme of Indian history I.e wafer fabrication facility and Kaveri engine...

There is two engine programme running in parallel with section of third one in Jan 2017 . First with the help of snacma of 88/57 kn with blisk and second generation scb with engine intended to fly in Tejas in 2018 . Second one is based on k8 , which gtre is running on its own to master core ...

No 4 point is my main concern , if they give us the tech of blisk and scb mass manufacturing tech , they will solve our problem . Rest we have to do our self .

K 10 will be 110 kn safe rated , with 120 kn to 125 kn max . 400 cores fund allocated with start of project from 2017 , with project completion date of 2020 . K9 will be 95 kn max with safe rated to 88 kn wet and 57 kn dry with 30:1 pressure ratio with wide cord blade with fourth stage blisk...

Blisk and scb from snecma perhaps till indigenous replacement in Kaveri snecma engine .

yes you are right , but first replacement of f404 come alive then we can target for higher thrust variant . And gtre also working separately , they can come with higher thrust . If this Kaveri snecma certified 2020 , we will have a better engine than f404 for Tejas mark 1A , with almost 70%...

Kaveri snecma going for 30:1 pressure ratio , 92 -95 kn wet thrust , ~ 1050 kg weight , fourth stage blisk , scb with thermobaric coating , 55 - 60 kn dry , with tet of ~1600 *c . Also gtre working with their own separate engine . Very unconfirmed sources , so please not ask me for link . I only...

SCB is there in htfe 25 of second generation or higher , also blisk , wide cord blade is there in htfe 25 . These all going to be in Kaveri with also thermobaric coating of plasma or ceramic coating to achieve tet . There will be better metallurgy in cold section to handle higher centrifugal...

You will be surprise to hear that new of Tejas fly with Kaveri will come earlier than 2019 . In 2019 it will be full combat menuver for international community with certification to be completed in end of 2019 and Kaveri goes in mass production in in 2020 . Actually Kaveri mainly lagging in...

DMRL develop nickle based superalloy DMD4 and DMS4 for directionally solidified and single crystal respectively . These are 100 c better temperature durable than directionally solidified blade used in Kaveri 2011 status engine . These single crystal blade certainly have to go in Kaveri but what...

No such report in media /net . One guy self claim to be closer to project has said that 1. After integrating blisk and scb a weight reduction of 100 kg from 1250 level of 2011 has occurred with improvements in thrust but exact figure of thrust not in public domain. 2. Kaveri snecma lead to...

I can safely say that this offset of snecma Kaveri also have another dimension . Who will like to loose a business of 2000 engine for amca at the cost of 6 to 8 million totalling to 12 to 16 billion usd . I think snecma Kaveri will be ~65 kn dry and ~95 kn with a tweaking of better metallurgy...

So a need of foreign expert needed . The view of mod was that even fixing Kaveri in form of consultancy will give our scientists a chance to quickly acquire the tacit knowledge and know how of this complex technique power pack fixation . And playing around it in future lead to fixing Kaveri...

And also each generation of scb is different from previous generation by 70 to 80 c . Major chunk of temperature come from thermobaric coating , which may be in order of 200 to 300 c depending on techniques . Now it is turn of mod to realise the amount of work to be done . They quickly engage...

But new mod , better scb is just beignig of challenges. New scb mean higher tet , higher rpm , higher centrifugal force on low pressure blade and disc in new conditions of higher temperature and pressure . This means new alloy of better tensile strength and temperature durability for disc ...
