Malaysian public survey on the current carry-on luggage handling onboard commercial transport aircraft

The current handling of carry-on luggage inside the aircraft cabin has led to several issues such as inefficient boarding and disembarking processes. Due to the number and size of current carry-on luggage, the boarding process has been slowed down due to aisle blocking and luggage overcrowding in the overhead storage bins. To improve this situation, an automated cabin luggage system has been proposed. A public survey has been conducted to explore the general passengers' perception of current carry-on luggage handling inside the cabin and to identify potential rooms for improvement that can be catered by the automated cabin luggage system. The responses obtained from the survey indicate that the current carry-on luggage handling does have several weaknesses that can be improved by the proposed automated system.

Study the Ferro-Hydrodynamic Characteristic on FHD Bernoulli Model

A ferro-hydrodynamic ( FHD ) model, based on modified Bernoulli theory, to estimate the average ferro-flow velocity is developed in this study. In which, the effective viscosity, strongly dependent on the magnetic intensity and volumetric concentration of ferro-particle, is considered. Referred to the Langevin function, the induced magnetic pressure together with hydraulic head as well as frictional head successfully formulates the modified ferro-Bernoulli model .To correct the analytic results, a self-designed experimental mechanism, equipped with light gate and current-carry solenoid, is set up as well ,which is used to measure the average velocity of piping flow via the duration recorded for ferro-fluid passing through both light gates While compared with experimental results, a good agreement of analytic solutions will be delivered within the working magnetic intensity ,0~36 mT, and the flow velocity is found to be significantly reduced during initial magnetization 0~12 mT as the working condition, subjected to ferro-concentration 0.04~0.4 at temperature 25 oc~45 oc, is specified in this study.
