Do engines advance separately from airframes? I understand that 1 R&D advance needs 1 R&D engine of the right type.
Separately, and that's right
In RA3 for example both the Judy and its engine the Aichi 60 appear at 42/10 with no research allocated. But lets say for example I want to advance both by a month.
Would that mean I need 100 R&D airframes plus 100 Aichi engines AND an additional 100 Aichi engines for the engine to move forward at the same rate as the airframe?
You need 100 points, not 100 engine factories (or airframes) to advance. I don't know about RA3, but I would say that R&D for engines and airframes seem to work at the same rate;So say you are getting 30(0) = 30 points/mth frames, you'll need the same for engines 30(0).
*1* Individual airframe factories are pretty much limited to 30 points per month. [Edit] Both frames and engines are inefficient over 30 R&D
Another example (and more important in this case) is the Nakajima Ha-45. Lets say I want to move the george from 43/5 to 43/3. That would mean that I would have to move the engine forward from 43/9 to 43/3. Would that mean I have to build enough Ha45 engines to get 200 engines just for the george advancement, plus X amount of engines to match R&D airframes for Franks,Frances,Peggys and 600 PLUS Ha-45 on top of those requirements?
If this is the way it works, then I would probably also need even more then the above numbers of extra engines, as die rolls mean not every 100 will produce a 1 month advance
Once again you are confusing factories with points. Points are accumulative, factories are per month. You just need to work on the same rate of advance.
So say you get all the George factories repaired by 11/42, giving you 4 months to produce 200 points for the 2 months advance. You'd need 200/4 = 50 points/mth = 30(0) + 20(0)
Whereas the engine factory can be 50(0) IIRC see *1* above. I will double check this with a test later to ease my mind.
Tested and I was incorrect, you'd need a 30(0) and a 20(0) engine factories too.
