WP 1 is related to Management including risk management, coordination, and communication within the project team as well as with the TM, is done by Villinger. In order to ensure proper management and coordination of the project, weekly telecons are being held between the TM and the consortium.
With regards to disseminationa and exploitation, several actions were taken also after the project End. A workshop with several people from Propeller industrie has been held to show possibe rotorblade/propeller IPS applications. In addition, attendance during SAE conference in Vienna 2023 was used to dissiminate the project results.
WP2:
Under the framework of WP2, the design and development of the heater layer-based IPS to be incorporated into a prop rotor or panel composite structure will be delivered. CFD simulations were performed in order to determine the requirements for the heater layer in terms of location and arrangement of heating zones on the rotor blade and power density for anti- icing and de-icing strategies. A number of anti-icing and de-icing zones along the rotor blade have been defined to ensure proper ice protection properties.
WP3:
The general works performed in WP3 was the realization, verification and preliminary testing of the Villinger heater layers on coupon level.
Partner CEST has performed extensive material characterisation and qualification tests of coupons combined with the evaluation of materials safety and compatibility in accordance to the DO160 specification. For this testing campaign, rectangular-shaped flat coupons provided by the TM to Villinger and equipped with different heater layer configurations have been used.
The outcome of this test campaign was to show compliance against all required environmental hazards and to test surface quality and uniformity of the Villinger heater layer applied on GFRP coupons.
WP4:
In WP4, structural element test specimen, representative of the actual system design later applied to a blade specimen, were manufactured for structural testing at Aviatest's facility. 5 coupons, consisting only of the structural laminate base material, without electrical elements included, were tested to establish the laminate strength and failure modes.
Furthermore, differernt Coupon types with functioning electrical elements, including the heater layer, busbars and cables were produced in order to establish the material testing in WP6.
WP5:
In WP5, the static specimen heater mats were produced successfully implemented into the environmental demonstrators.
In addition, heater mat coupons for various tests were manufactured
WP6:
In WP6, structural testing of various test coupons is done. There were some failures in the bus bars as well as in the substrate materials, for this reason. the loads were revised and additional testing is performed. The endurance testing could be finished.
WP7:
The main works performed in WP7 was preliminary testing of the environmental prop rotor spin demonostrator as well as the static testing on two demonstrators (mid-wing and root specimen) in the RTA Icing Wind tunnel.
WP8 & WP9:
During WP8 and WP9 the results from both environmental and structural testing were analized.
