Brochure: Testing and Evaluation – Structures

NLR acts as a one-stop-shop for “Non-Standard” testing of aircraft parts, structures and materials. The traditional structural testing has evolved, it includes energy transition related testing: deep cryogenic, hydrogen, fuel cells, and hydrogen electric power trains (in full or its components). We have the capability to offer you inspection, testing, characterisation and failure analysis. For […]

Upgrade of the rotorcraft noise model (NORAH)

Current international guidance on aircraft noise modelling is limited to fixed-wing aircraft, thus not covering rotorcraft noise. In the NORAH2 project, rotorcraft noise modelling guidance was issued and implemented in a software prototype. The hemisphere-based approach of the NORAH2 project is suitable for modelling rotorcraft noise of helicopters, as well as noise created by future […]
