I am providing some tests I did with the projet 98 RC Drone fiber glass 3d model. (2500mm ws; 1080 lg; @60km).

Velocity Tests:

Pressure Tests:

Video Test:

98, aerodynamics, analisys, drone, mq-9, nitro, planes, projet, reaper, uav

Because the analyzed part was not built to function as part of the lifting system.

i do not understand what that drag coeficient relates to? the drag force around 7N seems normal ( around 200W to fly level is not great but it is ok ) but with that drag force S.Cd is around 40 10-3 so how can the drag coeficient be over 1??

I'm will use Autodesk Inventor for stress analysis. The drag coefficients is really awfully high for an airplane.

I'm use a 3ds Max for modeling and use Autodesk Flow Design for analysis. I use a plan for nitroplanes.com.

The drag coefficients seem awfully high for an airplane. I guess exponent is missing?

First frame shows interesting layer separation at the forehead.

Very interesting. what program are you using for analysis and how did you digitize the R/C reaper?
