Objectives: 

The main aim of the CA3ViAR project is the design of an Open-Test-Case Fan geometry that will develop instability mechanisms which are representative for UHBR fans of civil aircrafts and perform a comprehensive experimental investigation to measure aerodynamic, aeroelastic and aero-acoustic performance in a wide range of operational conditions.

Experimental tests will be performed in the Propulsion-Test-Facility (PTF) of the Institut für Flugantriebe und Strömungsmachinen (IFAS) of Braunschweig, Germany. The proposal CA3ViAR will target several objectives. Initially a literature review of the main issues affecting composite UHBR engine fans will be performed by the Technische Universität Braunschweig (TUB).

The design of the Low-Transonic Fan (LTF) will be led by TUB with support from DREAM (an Italian SME) in terms of aerodynamic shaping as well as from Leibniz Universität Hannover (LUH) and IBK in terms of aeroelasticity and aeroacoustics. The LTF test article, to be mechanically designed by IBK, will be conceived in a way to experience aerodynamic and aeroelastic instabilities in an expected way during wind-tunnel operations.

Manufacturing-related activities will be performed under IBK supervision through subcontracting to well-recognized manufacturer specialized in rotor blades and parts made of composite and metallic materials, while requirements for the test article integration will be provided by TUB, responsible of WT instrumentation and operations. The execution of the experimental tests aimed at measuring fan instabilities (e.g. stall, flutter, etc.) will be performed by TUB with support from LUH.

The last technical phase of the project will be the calibration and the eventual validation of aerodynamic, aeroelastic and aero-acoustic models according to WT test data acquired in the PTF. This last technical phase will be led by LUH, with a strong support from all the other partners.
