The Airframe Noise Reduction Challenge David P. Lockard Langley Research Center, Hampton, Virginia the airframe noise of an aircraft in this “clean” configuration would only be about 8 dB quieter on approach than current civil transports. To achieve the NASA goal of 10 dB noise reduction will require 3 Effect of Component Noise.

Aircraft Airframe Noise and Installation Effects- Research Studies Leung CHOI CHOW, Pierre LEMPEREUR, Knut MAU The principal aircraft and engine manufacturers in Europe are facing increasing pressure to reduce aircraft noise clic-clelia.com by: 1. Almost 40 Years of Airframe Noise Research – What did we achieve? Werner Dobrzynski Airframe noise is generated through the interaction of turbulent Landing Gear Noise – Baseline WT-Studies B 1/16 scale MLG Baseline full scale or close to full scale LG tests. The noise from such aeroplanes during approach is largely dominated by airframe noise, i.e. the noise generated by the interaction of flow and those aircraft components deployed for landing, such as the landing gears and the wing high-lift clic-clelia.com: Werner Dobrzynski, Hanno Heller, Jan Delfs. Aircraft noise pollution is a harmful noise effect produced by any aircraft or its components during the various phases of a flight. Sound production is divided into three categories: Mechanical noise—rotation of the engine parts, most noticeable when fan blades reach supersonic speeds.

Various papers on numerical methods for engine-airframe integration are presented. The individual topics considered include: scientific computing environment for the s, overview of prediction of complex turbulent flows, numerical solutions of the compressible Navier-Stokes equations, elements of.
