Engine liner testing
The design and optimisation of engine nacelle and exhaust acoustic lining materials is crucial for reducing noise pollution and improving overall engine performance. However, verifying the effectiveness of these materials can be a complex task. NLR can assist in the design and experimental verification of engine nacelle and exhaust acoustic lining materials, as well as provide a quick comparison of the damping characteristics of various acoustic liner panels. Additionally, we can help validate the effects of grazing flow on the acoustic impedance, ensuring that your engine liner design meets the required standards and performs optimally.
