This paper studies several problems that may exist in the aerodynamic design of low Mach number general aircraft. and discusses the design characteristics of the pressure distribution of some related airfoils while part of the characteristics is verified by a multi-point laminar airfoil design case. Firstly. several issues which exist in the aerodynamic design of low Mach number gener... https://www.roneverhart.com/Dudley-ASA-Thunder-ZN-Hycon-12-52-300-Softballs-4A-068Y/
