HAL HTFE-25 & Other Indigenous Aero Engines Developments

A photo of the Manik engine from RM Rajnath Singh's visit to ADE.

I don't know what to make of it,


" The Jaguar fighter aircraft of the Indian Air Force was taken from France. But its maintenance and overhauling of its engine etc. is done in India only. Over a period of time, many engine parts are replaced. MIDHANI indigenized the Jaguar engine. In technical tests, the engine developed by MIDHANI was found to be superior to the original Jaguar engine. Today, Jaguar engines use parts from MIDHANI and are now in regular supply. MIDHANI’s components are flying regularly in Jaguar fighter aircrafts. "

Nothing much . The PRO of MIDHANI is doing a good job & deserves a raise & promotion.
 
This is how the indigenisation is initially asked to carry out. make the small, sometimes critical parts here. basically Govt asked all subsystems should be developed or made here gradually. mandatory 50% content in evry tender, that goes to raw materials stage as well. Midhani already made the raw materials & some components and started investing in expanding. If this is carried thru we might see some good effect in 5 years time.

Lets see how successful they are in improving MKI's engine.

We need a Engine consortium where the technical expertise of GTRE, HAL and other players can be under one roof.

HAL has had ToT of AL31F, licence of RD33 Series 3 and Adour engines. And GTRE has Kaveri.

Its criminal that DRDO is doing the work on Kaveri while the ToT of AL31F lags away with HAL.

That ToT was a purely mfg ToT not an R&D level ToT . Besides , how have you assumed that the other agencies namely DRDO , MIDHANI , GTRE , ADA , etc wouldn't have had more than a peek at the entire engine.

How else are we indigenizing components & sub components of it ?

AL31F was the deepest ToT on engine any nation will ever provide to any other nation.

The GE licence production which a lot of guys here jump about will impart us with similar levels which the RD33 licence did.

No license production of GE 414 will happen mark my words. The only engine that Americans have ever agreed for license production is F110 and that too for a nato member. Even that nato member is the biggest sub contractor of GE under a JV.

Lot of guys? Lol. Just 1 guy. Besides if you've followed the progress report on this program at B R F, lots of juicy stuff back in the day basically hinting at GTRE studying the entire engine inside out. A lot of R&D we did on it wasn't approved by the Russians & they didn't like it one bit when we usually presented them with fait accompli on the indigenization of a number of sub components.

Basically in the early days the flutter & thereby vibration caused in the engine which led to a couple of crashes were thanks to import substitution. Besides a lot of improvements were made to the design of AL31F or at least refinements carried out if you were to believe the guys at B R F.

Now I'm quoting purely from memory here when I used to follow a few programs on B R F, D F I, P D F etc circa 2010-15.

License production is very much possible but it'd be classic screwdrivergiri of CKD or SKD kits at the onset & for quite a few yrs before we move up the ladder in a very graduated manner. And in 2 decades we may get to AL31F levels, if not exactly there, in the same bandwidth.
