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...

This paper presents a solution to the landing gear system case study using Event-B and Rodin. We study the whole system (both the digital part and the controlled part). We use feature augmentation to build an abstract model of the whole system and structural refinement to detail more specifically the digital part. The required safety properties are formalised and proved. We propose a specific a...

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...
