A Preliminary sizing tool for minimum weight aircraft wingbox structural design
Mert, Mesut; Kayran, Altan; Department of Aerospace Engineering (2018)
This thesis presents a preliminary structural sizing tool for the design of aircraft wingbox structures. The primary goal is to obtain the least possible structural weight for a metallic wingbox by using the thin walled multi-cell box beam methods in the literature as part of an iterative process. An automatized tool based on simple and quick approximate methods is created to take advantage in the preliminary stages of design when several possible structural alternatives are being investigated. Airfoil data...
A New production methodology for vacuum infusion process of advanced composite structures
Poorzeinolabedin, Mohsen; Parnas, Kemal Levend; Department of Mechanical Engineering (2017)
Vacuum Infusion Process (VIP) is one of the Liquid Composite Molding (LCM) methods which are widely used in out-of-autoclave processes especially for the manufacturing of large scale composite parts in aerospace, automotive, wind energy and marine industries. In order to simulate the infusion process, the permeability of preforms is an essential parameter. Absence of any standard is a challenge for the determination of in-plane permeabilities of a preform. The first objective of this study is to develop an ...
A numerical simulation study on mixing of inert cushion gas with working gas in an underground gas storage reservoir
Kilincer, N; Gumrah, F (2000-12-01)
The cushion gas, providing the pressure energy necessary for withdrawal of working gas, makes up the largest part of the investment in underground gas storage projects. The suggested method of reducing this cost is the replacement of some part of the cushion gas with less expensive inert gas, such as nitrogen. In the replacement, there might be some problems due to mixing between natural gas and inert gas. Turkey has sharply increasing demand for natural gas. The constant imported gas and varying demand thr...
