Lortek, a private technological centre deeply involved in additive manufacturing technologies, is the coordinator of several European projects related to metal additive manufacturing. One of this European project is FLOWCAASH, which belongs to Clean Sky 2 framework and Airbus is the topic manager.

 .

In FLOWCAASH project, Active Flow Control actuators have been designed and manufactured at aircraft scale using Selective Laser Melting (SLM) technology and Ti6Al4V alloy. One of the main challenges of the Pulsed Jet Actuator (PJA) is the geometrical complexity since it needs to be installed in restricted spaces, in between the wing and nacelle of UHBR (Ultra High By pass Ratio) aircraft engines. The PJA is a relatively large part and is composed of several channels with abrupt and narrow curvatures. Nevertheless, […]
