A Smart Icing Detection System for any Location on the Outer Aircraft Surface 2019-01-1931
Given approximately one million small and light aircraft in the field, icing detection and icing quantification of in-flight icing is still an open research topic. Also, means are available to de-ice on ground and while airborne, however, these devices can not be efficiently controlled due to the lack of a suitable control system. Especially, pneumatic boot systems require activation just in the right instant of time.
In a collaborative research project between 2015 and 2018, a technology of energy self-sustaining, wireless, self-adhesive smart sensors for industrial sensing in an aerodynamic environment (i.e. wind turbines) was further investigated to fulfil aviation requirements.
In this paper, both the system design and first test results during flight into known icing (FIKI) of such a retrofittable sensor are presented. It will further contain details on simulation for verification of the test results and also measurement results from aircraft flying in icing conditions.
