That aircraft looks so good Peter; well done on its presentation! Are those
pieces
of cardboard at the radiators to help maintain engine temps?
Chris, variations in colour indicate changes in airspeed velocity; there is a
scale
if you zoom in and the velocity applied is 51m/s or 100kt; low velocity is
not necessarily a bad thing however its an indication of turbulence induced
drag around exit vent openings and rearward of aft surfaces as slower and faster
moving air rejoin, getting these two velocity streams to combine back together
more smoothly is a desirable outcome... one of my test pilots has just suggested
trying vortex generators; will be interesting to see if that has any desirable
affect... will be interesting to see just how much total drag can be reduced
and how that might be achieved!!
For the technical minded the test was carried out with theta, beta and delta all
set at zero, alpha is equal to angle of incidence. Returned output forces NM
(x) -587 (y) +4424. (Results are indicative only and may vary substantially
between
individual built aircraft)
