Hi,
The best way I can explain static/dynamic is static thrust is what you need to get going, basically how much air your fan
can shift at full power when the model is stationary , dynamic is the thrust change when the model is moving through the air, this is the result of inlet/fan/tailpipe combination.
Essentially if you are looking for static thrust then go for a Byron type pusher fan, if you're looking for the best
dynamic then go for Dynamax/Ramtec tractor type fan, looking at your drawing then I suggest you move the fan rearwards, you
need more inlet than you have, also do you want the weight forward ??
Regarding the tailpipe then if you were using a pusher fan then a straightforward taper is fine, but using the Dynamax then
you need to apply area rule (as per my previous entry) to maximise performance. Hope the makes sense.
Anyone got a picture of just the tailpipe assembly they can post, I dont unless I strip out a model, this would help getting the
point across....Mike
