How Lift Is Actually Generated
The equal transit time story is wrong, and the popular Bernoulli explanation is incomplete. What actually produces lift is flow turning —…

Why Reynolds Number Dominates Small UAV Design
Small UAVs operate in a regime where aerofoils designed for full scale aircraft quietly stop working. Understanding why prevents a class of…
