In Spring 2020 I designed a blended wing body microjet concept during my Aircraft Design course. The jet was initially sized using a class 1 weight estimation before going into more detail by sizing the engines and all aerodynamic surfaces for takeoff, climb, cruise, and landing. The rudder size, airfoil profile, wing location and engine location were iterated to make the plane aerodynamically balanced and naturally stable. Using the calculated dimensions, I created a conceptual surface model of the plane.
