I think it’s very unlikely that you see only a 50% reduction in overall production ramp time for the WS-15. Entire bodies of process knowledge and production systems didn’t exist for the WS-10 that now exist for every new engine going forth. The 5-10 years for the WS-10’s production to ramp up was as much about building the general infrastructure and production knowledge to do advanced turbofan production. If you take 10 years to learn C++ from not knowing *any* programming language and then try to learn Java your speed of learning isn’t going to be reduced just by half.Almost certainly would help WS-15 production set up. Which is why I said 5 years instead of the 10 years it took to take the industry go from WS-10A serial production in very limited numbers to current WS-10B and WS-10C batch production in current impressive numbers (relative to past but not impressive by US production rate for F110 in the past and F135 now).
