Research of Airplane Waste Disposal System Tank Characteristics by Method of Numerical Simulation
The modern design enhances the role of preliminary research in aircraft development. Reducing iterations in the process of making conceptual decisions, along with the requirements for the project, and obtaining the most reliable models of the future system is one of the important tasks facing a design engineer. The article considers one of the life support systems designed to satisfy the physiological needs of the human body – a vacuum-type waste disposal system. One of the critical elements of the system is a waste storage tank. An important stage in the design of a tank is the determination of its weight and size characteristics in the early stages of development. The tank filling process has a significant influence on these characteristics which is crucial for the placement of equipment in it. The aim of the work presented in the article is to study the process of filling the tank with the help of numerical simulation methods. The results obtained in the process of numerical modeling make it possible, at the preliminary design stage, to evaluate the required air gap, to determine the total volume of the waste tank.
