  Some questions on re-engineering the HF 24 Marut There has been a lot of twittering about the pros and cons of reviving the Marut. Many of the doubts raised and comments made were by people who had evidently not read what was being said. Dr. Sastry, however raised some questions which I elaborate here. Dr. Sastry,s questions I have put in bold.     Would the engine issue not crop up again unless we can somehow use the Adour for which we seem to have the skills to make currently. The original orpheus is probably to be ruled out?   My view is that Orpheus was orphaned at birth. This engine is cheap ,simple and easy to recreate. Getting 30kN from a basic Orpheus should be a given . From my Industry experience I know how sensitive turbomachinery is to small improvements and ,conversely ,small carelessnesses. You will note that  I have said that there are 4 foriegn engines available this means that teh Adour /Honeywell F124 are in my mind.. However the Orpheus would be serious
