Aircraft airframe noise: Effect of bogie inclination on the unsteady flow field and noise production
Computational methods are used to determine the flow field around a simplified landing gear geometry and the far field noise levels generated by this flow. The focus of this research is on the influen....

Aircraft airframe noise: Noise control of landing gear using pereforated fairings
Landing gear noise can be the dominant component of airframe noise, especially for larger aircraft. The interaction of the airflow with protrusions and cavities gives rise to unsteady flow phenomena c....

Aircraft airframe noise: Large-eddy simulation of jet interaction with a wing
Jet engines and airframes are the two main contributors to aircraft noise, with the latter including both high-lift devices and landing gears. To achieve reductions in aircraft noise, it is necessary ....

Aircraft airframe noise: Investigation of aircraft noise in steep approach
Airframe noise has been found to be the dominant source of noise for an aircraft on approach to landing. Airframe noise is made up of the HLD noise and landing gear noise. In order to reduce noise on ....

Aircraft airframe noise: Blowing for bluff-body noise control
Landing gear noise is a major contributor to airframe noise. Wakes from upstream components impinging on downstream components are a significant source of noise. This work investigates the use of flow....
