Chinook S


The Chinook S, designed by Fred Hermanspann and Art Penz, first flew in 1996, as an improved version of the original Chinook of 1993. Approach control is by full deflection trailing edge flaps. Both the flaps and main wheel are hydraulically actuated. The sailplane has been used to study the effect of rain on airfoils, and dynamics at the stall.
