Luft 44 could be real messy at times. Not sure I like pulse jets.
But your engineering processes are well worth watching. 
Might canard be better than tailless for flight stability? |
hi Maurice,
After several tries at this, biggest problem was getting to complicated and heavy, real heavy. Wanted something simple to do and light weight.
As it is right now stability could be an issue, only have a Static Margin of .68". This is an indication of stability. It is the distance from the CG location to the Aerodynamic Center of the model.
The aerodynamic center is a measurement of the lifting surfaces and their related "aerodynamic center". It is a complicated process. Anything forward of the CG moves the Aerodynamic Center forward.
A canard moves it forward big time. You need to have the Aerodynamic Center (AC) behind the CG location for a stable aircraft. As it is now the AC is located .68" behind the CG. I would be happier if it was an inch!
To install a canard would involve a much more complicated "control" design. With a flying wing, Elevons can work as the sole control surfaces.
Elevons control Roll and pitch, simple enough to use two servos for everything.
Rudders will be fixed.
