Aerodynamic Design of a Tailless Aeroplan

Acta Polytechnica, 2001
The paper presents an aerodynamic analysis of a one-seat ultralight (UL) tailless aeroplane named L2k, with a very complicated layout. In the first part, an autostable airfoil with a low moment coefficient was chosen as a base for this problem.
