Hi im a first year ME student and im attempting to design a twin boom pusher aircraft as a personal project, below are the specifications i went with:
-NACA 4412 wings, 0.1726mm avg chord with a 0.6 taper (AR=7)
-NACA 0010 tail airfoil tail volume coefficient of 0.5
- horizontal aspect ratio of 4 and for the vertical fins aspect ratio of 1.5
- horizontal tail span of 0.3914m and vertical tail span of 0.127 (Vv=0.04)
- horizontal tail chord =0.0978m vertical root chord =0.0978m, tip chord = 0.0712
-0.47m tail moment arm
I read that the aircraft becomes unstable if my horizontal stabiliser sits in the path of the propeller. How should i go about designing my tail then? Is it a major issue? Also i would really appreciate if anyone has feedback on the specifications i went with, I am very new and this is the first aircraft ive ever designed.
