Airplane Update #4

Hey there, just wanted to post some updated parameters on the newer airplane design that implements some of the design changes I wanted to make. The detailed math is below, but the most important changes involved moving the wings down to create a low-wing monoplane (it looks more aesthetically pleasing, and it'll make placing landing gear much easier), adding a wing dihedral angle of 11°, increasing the aspect ratio of the wings from 7 to 10, and adding an angle of attack of 8° to the wings. From this values such as flight speed, lift coefficient, required power, center of gravity, and spiral stability were determined (among other factors), and overall it seems that the aircraft will have greater authority over its pitch and roll while also not needing as much power as I previously thought to fly.



 I'll be posting the CATIA model of this plane in the next couple days or so, along with (hopefully) the power-plant and propeller.
