Yeas, what stopped us from developing a higher shaft power Turboshaft engine based on the experience we gained?
Also RR-GTRE proposed engine is 110kn asper many reports, in future if IAF wanst a heavy class stealth fighter like f22 then we need minimum 150+ kn engine . My query is that will india be able to develop such engine without external help ? We have an example of Shakthi engine that the experience gained from Shakthi project didn't work out with us developing to a higher rated engine for imrh.
HAL is working on turboshaft engines. But this kinda project is long term and takes a decade or more. So you will obviously not see it right now.
