This paper describes third aircraft model with 2 degrees of freedom. The aim of this study is to develop a mathematical model for investigation of adoptable landing gear vibration behavior and to design Proportional Integration Derivative (PID) classical techniques for control of active hydraulic nonlinear actuator. The parameters of controller and suspension system are adjusted according to be...

During its near-ground hovering phase a Short Take-Off and Vertical Landing (STOVL) aircraft creates a complex three-dimensional flow field between jet streams, the airframe surface and the ground. A proper understanding and numerical prediction of this flow is important in the design of such aircraft. In this paper an experimental facility, used to gather validation data suitable for testing C...

Abstract The sonic load of the engine is input for cabin noise design and acoustic fatigue verification in civil aircraft. Based on static database, an engineering prediction method blended wing body aircraft flight developed. In process prediction, sound source position correction, geometric diffusion, effect airframe scattering component are considered. air-frame level simulated analyzed. ove...

Beamforming is an imaging tool for the investigation of aeroacoustic phenomena and results in high dimensional data that broken down to spectra by integrating spatial Regions Of Interest. This paper presents two methods enable automated identification sources sparse beamforming maps extraction their corresponding overcome manual definition The are evaluated on scaled airframe half-model wind-tu...
