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 ...

One of the most important components an aircraft is landing gear. In today`s modern gears, mostly oleo-pneumatic shock struts are used. Analytically, gear can be modeled as a mass-spring-damper system. The model used in study included such strut, tire and wheel. Furthermore, tapered metering pin was added to order control area orifice by which hydraulic oil flows during act impact force. Landin...

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 ...
