Aeolus ASP

Aeolus Aero Sketch Pad (ASP) is an aerodynamic design application for UAVs, drones, and light aircraft. It allows you to easily model arbitrary fixed-wing aircraft concepts and to optimize model parameters (such as wing shape, or flight condition) to meet your design requirements.

Now you don't need to be an aeronautical engineer or study complex aerodynamic equations to design your own drone or light aircraft, instead you can use Aeolus ASP.
It allows you to test and validate your ideas and see the impact of design changes on the aerodynamic performance of your drone.
