Bonjour
Le nouveau multi de BJ craft est en test.
Les explications du concepteur d'avoir un fuselage moins haut
"BJ CRAFT New G2.5 Fuselage
As you know well BJ CRAFT share one fuselage for many different models.
In design of F3A plane geometry, Fuselage is a little aerodynamic effect.(except vertical tail)
So plane has completely different character/performance by the design of wing (main, tail, cannard & nose moment) geometries , even if using the same fuselage.
But airflow of fuselage can`t be calculated, to understand that you need a lot of Test/Feedback from all over the world
Air flow of G2 fuse has been understood (for 5 years), so Epilogue is stable for all over the world.
G2.5 fuse has smooth surface and shorter tall than those of G2 fuse.
Special aerodynamic things (Side intake. keel. canard. fin. etc) were deleted.
They have their own aerodynamic effect but the volume of the effect is not the same all over the world.
some places the effect are good, other place they are not good (struggle, confuse)
I want that my production model has average performance (balance) in all over the world. so I deleted those things for betterment.
The balance of my model is not top class but is suitable for all over the world.
Smooth surface presents simple airflow, that makes stable aerodynamic force all over the world
The side area of G2 fuse (Both cannalizer plan Fuse ,biplane Fuse) was resulted too large. so made it's tall shorter.
Reduced volume of fuse enables light weight. which is good merit for easy production, improve finishing quality or reinforce landing gear mount.
This is also extend life of your plane
Let`s look and see how it goes
After 5 years what result shall be comming out !
# Look carefully my pictures as they have hidden spoiler always.
Paradigm & Sky!
