AERODYNAMIC PROFILE FOR AIRCRAFT AND WIND ENERGY PLANTS AND METHOD FOR MEASURING ICE THICKNESS ON AN AERODYNAMIC PROFILE

摘要

An aerodynamic profile (10) for aircraft and wind energy plants comprises an aerodynamically formed structure (11), in which, for example, a phased ultrasound emitter arrangement (12) is arranged, which emits ultrasound waves in particular directions (R1, R2, R3) during operation to determine the thickness profile of a layer of ice (8) on the surface of the aerodynamic profile (10). The structure (11) is, for example, a fibre composite material arranged around a foam core (14) the ultrasound emitter arrangement (12) being laminated in the fibre composite material. During measurement of the ice thickness ultrasound waves are transmitted to the surface of the aerodynamic profile (10) and ultrasound waves reflected at the boundary surfaces of the ice layer (8) are detected, the ultrasound waves being transmitted to various particular positions on the surface of the aerodynamic profile (10) and at least one region of the surface is scanned by means of the targeted ultrasound waves in order to determine the profile of the thickness of the ice layer.
