Noise predictions of realistic landing gear configurations are obtained combining high-fidelity CFD simulations and the Ffowcs Williams–Hawkings (FWH) acoustic analogy. The aeroacoustic prediction such a complex aeronautical system depends on geometry fidelity ability mesh numerical method to resolve important flow features responsible for noise generation. To understand role small components i...

An exploratory computational investigation using RANS & URANS was carried out to understand the aerodynamics around an isolated single rotating wheel with decreasing ground proximity. The wheel was initially modelled in free air conditions, then with decreasing ground proximity and increased yaw angle with rotational speeds. Three speeds of rotation were applied to the wheel so that the effect ...

Gears are the most important parts of rotating machinery and power transmission devices. When gears engaged in meshing transmission, vibration will occur due to factors such as gear machining errors, rigidity, impact. The traditional FxLMS algorithm, a common active has been widely studied applied system control recent years. However, it is difficult achieve good performance convergence speed p...

The landing gear, which is one of the most important mechanical systems in aircraft, structure that exposed to loads, and critical loads aircraft throughout its life cycle. In addition fact gear system must have high strength these long life, performance, low volume, minimum weight, cost are criteria. For this purpose, optimum design created by making a structural analysis using finite element ...
