Design of a frangible composite cover for missile launch tube

Akkaş, Ozan
In this thesis study, launch tube covers are investigated and a frangible cover is designed by using composite materials. Requirements which are derived from system level requirements are taken into consideration during the design phase. Suitable composite manufacturing method and materials are selected after literature survey. Load levels are determined by using experimental and analytical approaches. Material constants and limits are obtained from literature and coupon tests. Design parameters of the cover are chosen and determined by using finite element analysis. After conducting sizing of the cover by using finite element analysis, detailed design is completed. After that, a mold is produced in order to be used for resin transfer molding and cover prototypes are manufactured. A burst test set-up is designed and covers are tested in order to obtain inner and outer burst pressures. Experimental results are compatible with analytical results. Then the cover is used in firing test and desired results are observed.


Use of split-disk tests for the process parameters of filament wound epoxy composite tubes
Kaynak, Cevdet; PARNAS, LEVENT; ŞENEL, FİKRET (2005-08-01)
The aim of this study was to investigate processing parameters of continuous fiber reinforced epoxy composite tubes produced by the filament winding technique. For this purpose, split-disk tests (according to ASTM D-2290 standard) were performed for the specimens produced with two different epoxy resin systems, five different fiber materials and five different winding angles. By determining the hoop tensile strength and modulus of these specimens, the effects of three filament-winding processing parameters;...
Design of a tuned vibration absorber for a slender hollow cylindrical structure
Aksoy, Tuğrul; Özgen, Gökhan Osman; Acar, Bülent (Informa UK Limited, 2020-09-01)
In this paper, details of the design work for a tuned vibration absorber to be used on a hollow cylindrical structure is presented. The vibration problem is of resonant type and the tuned vibration absorber is designed to suppress the displacement vibration response of the free end of the slender hollow structure dominated by the contribution of its lowest transverse vibration modes. The structure is modeled using a commercial finite element software. Finite element model of the structure is verified using ...
Design of a high temperature erosion apparatus for testing of boiler tubes
Ergün, Hüseyin; Aydınol, Mehmet Kadri; Öztürk, Tayfur; Doruk, Mustafa (2013-07-25)
An apparatus was designed that enables the testing of boiler tubes against erosion. The apparatus makes use of a tube sample and simulates conditions similar to those prevailing in boilers in lignite-based power plants. The apparatus is composed of 3 components: a furnace for heating the sample, a loading system that allows the application of tensile stresses while allowing its rotation, and an erosion unit that delivers abrasive particles to the surface of the sample. The unit, as designed, would allow tes...

This paper presents a new design and analysis tool that is developed to be employed during the design process of axial flow compressors. The tool chain implemented by this design tool consists of five parts: a mean-line design tool, followed by a blade geometry parametrization tool. Then 3D blade geometry is created, next a high quality structured mesh is generated and completed by Computational Fluid Dynamics (CFD) solution. All components employed in the new tool are either new developments, or achieved b...
Behavior of steel-concrete partially composite beams with channel type shear connectors
Baran, Eray; Topkaya, Cem (2014-06-01)
This paper summarizes the findings of an experimental study investigating the flexural behavior of partially composite beams incorporating channel type shear connectors. Results from monotonic load testing of four full-scale steel-concrete composite beams and a steel beam are presented. The main effort focused on identifying the variation of strength and stiffness properties of beams with various degrees of partial composite action. Behavior of channel shear connectors in the composite beam specimens is rel...
