It destroys a liquid laminar layer on the cooled surface of the heat exchanger-crystallizer, increases flow turbulence, and decreases the average viscosity of pumpable ice.
Turbulence from the funnel and superstructure was severe enough that only three landing attempts were successful before further attempts were forbidden.
Flexibility allows the wing to be less susceptible to turbulence and provides a gentler flying experience than a similarly-sized rigid-winged aircraft.
