Despite being dressed up with fancy language and diagrams, this thesis amounts to a statement of the blooming obvious; stalls and spins are caused when laminar flow over an aerodynamic lift surface becomes chaotic.

Since this process is chaotic, repeated experiments under the same conditions may well give significantly different results. That renders computer modelling an imprecise science with regard to prediction of stall spin characteristics. The best that can be achieved is a prediction of a range of conditions where stalls and spins are likely to occur. Actual testing in full sized models will still require a test pilot and/or remote piloting from the ground.

Where this thesis does shine is in pointing out how minor changes to aerodynamic and other surfaces of an aircraft skin can have dramatic effects on performance and stall spin characteristics. Test pilots will still have a job in years to come although some of the more obvious risks could be reduced.
