CFD Analysis of a Typical Hydraulic Pressure Pipe Line in an Aircraft and Suggest Methods to Optimize its Stress and Vibration
The Hydraulic system of an aircraft is one of the most critical systems which operates essential services like the Control surfaces and Undercarriage system. Operators of Airlines and MROs have frequently complained about premature hydraulic line failures. This paper is aimed at studying the Fluid-Structure Interaction (FSI) of a typical hydraulic pipeline running in tandem with other pipe lines (which is a common feature in Aircraft) and suggest solutions to optimize the stress and vibration in them which is considered as the main factor for such catastrophic failures. Both CFX and FLUENT Solvers are used in our case. The analysis is carried out concerning suitability of material properties and support structure (for a high-speed aircraft) which are under the control of designers and MROs. The Von Misses stress has been simulated and analysed to substantiate various solutions being proposed.
