aerodynamic coeffcients.......
(OP)
hi!
im working with a autopilot (small uav) and need to calculate Ixx, Iyy, Izz etc. and all the aerodynamic coefficients (incl. the derrivates).
does anybody know were i can find these values for a full scale modern glider (or a RC version)????????
so far i have used a vortex lattice prog. and analytical methods described by [Roskam part I & II, DARcorp] and [Bandu N. Pamadi, AIAA] to do estimations.
SOS, really need the actual values.....
/never thrust calculations

RE: aerodynamic coeffcients.......
why not use for beginning what a lot of NASA people use: LINAIRPRO from Desktop Aeronautics, Inc. using simple desktop programs.
RE: aerodynamic coeffcients.......
You can also use AAA from DarCorporation, which is an exellent help.
Good luck
