For Freefly‘s AltaX aircraft, we have been optimizing their current blades using Aeolus ASP. The resulting blade shape proposed by the optimizer has been machined from Aluminum and tested a few days ago.

Efficiency improvements:

• Simulation (Aeolus ASP): 4.2%
• Test: 4.5%

With this good agreement between simulation and test we are now prototyping another blade that was found using Aeolus ASP promising approx. 19% efficiency gains.
