    Okay than its all good :D

    Uav Project.

    The v= 14,8 ms is for lifting 18kg, and one more thing, doesnt the value of cl have to increase with airspeed? cause in this simulation it is constant it only changes with aoa and when chanching wing parameters.

    Uav Project.

    Thanks Dana, I will not make the tunnelstab, but will make something more regular lika a vertical and horisontal stab S9027 (8%) (s9027-il) . I have a question is this wing setup good ? its clark yh.

    I made some designes of delta winged uavs, all values are at fixed mass of 18 kg and are at takeoff speed.

    Uav Project.

    Wow, my thanks for all that info. Thanks to your ideas i started to do some reasearch and stumbled on a program called xflr5 its a really good one. Now im doing tests there and finding the best airfoil for the flying wing designe. If i come up with something i will ad some pictures and parameters.

    Uav Project.

    Thank you for such an informative answer;) i will read these books as soon as i get my hands on them. for start i wanted to calculate lift for each airfoil and i run in to some difficulties, like for example how do i get the Cl . For example CLARK Y AIRFOIL (clarky-il) relative to airspeed, to...

    Thank you Wizzardworks for your reply, so i found an airfoil that might suit it EPPLER 435 AIRFOIL (e435-il) but i cant find the Cl (lift coefficient) relative to speed anywhere, i would like to make initial calculations about takeoff speed and required power. Is the wingspan 3m and chord...

    Uav Project.

    So i have to make a project of a uav at school. The criterias for it - Mtow 18 kg, Engine 2.0kw, and wingspan of 3 meters, Takeoff speed 45 kmh and cruise 80 kmh . The hard part is choosing a best airfoil for it, my first pick would be MH114 13.02%. So if anybody has a better airfoil to show...
