Abstract

Exact assessment and correct simulation of atmospheric turbulence is of prime importance for soaring. Raw power spectra of turbulence should be processed using natural parameter spectrum formula and evaluating phase angle relationships, too. This makes it possible to calculate turbulence-induced sailplane loads and motions using input spectral vectors instead of the usual spectral matrices. Records of thermal traverses are best modeled as regular nonstationary processes. Exploitation possibilities of these new developments in soaring include dynamic thermaling and a more realistic fatigue load simulation. Boundary layer research, too, may benefit from it.
