Re: Kaveri & Aero-Engine: News & Discussion

The Kaveri is ambitious. Like a student trying to crack IIT in first attempt. This is how GE did it: Their first iteration was F-404 -400, which was in dev from 1973-76, and launched in 1985-6 timeline. Max thrust was 71 KN or 16000 lb thrust. (Baseline was the J-79 engine, with same thrust goals). ...

No customer anguish, loss of face, etc.

RD-33 => 1200 hr (*Advertised)
M-53 => 2000 hr
F-100 => 750 hr
Al-31 (actual) => 500 hr

F-404 is 4000-6000 hr
F-135 apparently 20000 hr.
