Oct 17, 2015 at 5:56 comment added Shalvenay @Joshua -- I was simply saying that it's possible to build a liquid fueled rocket with 0 turbomachinery knowledge. Guidance definitely would be the problem -- the Chinese got solid fueled rockets of some variety working at that point in history, but never licked the guidance problem!
Oct 17, 2015 at 3:34 comment added Joshua They would use solid fuel of course. The problem is guidance.

Jul 9, 2015 at 22:15 comment added Shalvenay @pjc50 -- seconded for the most part -- I'm not sure if you need turbomachinery for hypergol fueled, pressure fed liquid rocket engines...
Jul 9, 2015 at 10:08 comment added pjc50 Too much vibration for compasses. Wind direction is always along the axis of the rocket. Gyroscope was invented in 1852. And if your culture doesn't already have controlled flight, it's unlikely to know how to build control surfaces to actually do the steering. Oh and liquid fuelled rockets definitely would require modern chemistry and turbomachinery knowledge. (I like to tell people about the book "Ignition!" by John D Clarke, a history of rocket fuel)
Jul 9, 2015 at 5:09 comment added user6760 as you are aware of the difference btw missile and rocket, can the people by the 15th century use clever mechanism for homing? such as detecting the direction of magnetic north and winds direction.
