RE: V12 500Hp diesel aero engine-video

RE: how does steerable nose wheel affect aerodynamics?

you have a nice sounding setup for an experiment. set up a mix to turn off your rudder and have the nosewheel remain active, see how it goes. a few mistakes hig of course

RE: wing loading

might not have the same vertical performance, but if you get the float angles tuned in it should go, just dont force it off the water, itll go when its ready. once in the air floats make enough lift...

RE: Spiral slip Stream is it real ?

on thing a stator does is trade air velocity for pressure using divergent ducts. a side effect of slowing the flow of a fluid in a smooth section is a drastic reduction in turbulence, which would...

RE: Spiral slip Stream is it real ?
