So what did godrej win before?
This is most likely for missile purpose , ie NASM MR kind. This was a tender about 4 months ago and at that time Godrej already had a contract for some other turbo engine. Godrej one is probably manik stfe off my mind, could be mistaken though. 20 numbers suggested it was to be used in uav or missiles more likely.
The main problem of Kaveri was afterburner. Is it an indication they solved the problem ?
Buy their shares. Listed company hai. Have bought some last month.
They are a very well known aerospace precision engineering company who had a higher export business due to the less developed aero industry within the country. They are part of supply chain for some of the big global OEMs. Their IPO was quite recent , I think from last December you could subscribe, many of us did. Azad used to make precision parts in some defence projects, in missiles mainly. This is probably the first time they are foraying into a lead integrator role, similar to what Godrej&Boyce, L&T, HAL etc do.
Ab yeh Bencho Azad Engineering Kaun Hai?....
The major problems of the Kaveri engine were the creep, screech & combustion instability. The last 2 problems were being caused by the afterburner. Creep related issues have been worked out with the application of a new Yttria stabilized-cubic zirconia bi-layer thermal barrier coating on the turbine vanes & blades.
DRDO reported that this new afterburner provided a stable wet thrust output. The new AB section also provided marginally higher wet thrust at marginally lower SFC.
They did show in one doc about plan to integrate kaveri on a tejas. I posted it somewhere, if that plan goes ahead then it is likely that kaveri is able to give around 80-81kn wet thrust in relatively stable condition imo, given MoD claimed 80kn class engine thrust capability.
Yes, and by the time the Tejas Mk1/1A fleet need a new engine the Kaveri should become fully ready. The timing fits. In the meantime, the dry Kaveri engine production line would be fully established & could be used for producing the full-sized engine.
Soooooo, what happened to it ?
