The present paper is a part of an effort to describe a methodology for designing an insensitive munition of type V against fast cook-off threat. Experimental investigation of boundary conditions is carried out in order to simulate fuel fire tests numerically for thermal analysis. The aim is to describe the boundary conditions for thermal analysis of the test item being exposed during the fast cook-off test. Thermal analyses are performed by the defined boundary condition (BC) in order to predict time to reaction. Comparison between the numerical results and experiments are also made. In addition, some information about the second part of the methodology is also provided.

Investigation of a generic warhead containing plastic bonded explosive under liquid fuel fire by numerical and test methods Şahin, Hakan; Kurtuluş, Dilek Funda; Narin, Bekir; Department of Aerospace Engineering (2015) The present work provides a design methodology for a munition against fast cook-off threat for type V insensitivity requirement. The experimental and numerical results for a generic test item (warhead) filled with a PBXN-109 explosive are presented. Two key points for the design of an insensitive munition against fast cook-off threat, which are time to reaction and critical vent area is studied. Dividing the problem as pre-ignition and post- ignition will allow one to manage this complex problem to handle e...
Development of a Design Methodology Against Fast Cook-Off Threat for Insensitive Munitions ŞAHİN, Hakan; NARİN, Bekir; Kurtuluş, Dilek Funda (Wiley, 2016-06-01) This work provides a design methodology for a typical energetic system to get Type V insensitive munition (IM) response against fast cook-off threat. Experimental and numerical results for a generic test item filled with PBXN-109 explosive are presented. Two key aspects of IM design against fast cook-off threat are investigated, which are "time-to-reaction" and "critical ventilation area". By dividing the problem to pre-ignition and post-ignition, the complexity of the problem is reduced. The first part of ...
Design of an inertia measurement device for stores Kılıç, Berkay; Dal, Hüsnü; Tüzün, Aydın; Department of Mechanical Engineering (2018) In this thesis, design of a device, which can measure mass properties of missiles or their sub-components in a single test setup, is expressed. An object, whose mass properties are going to be calculated, is attached to the device and three-dimensional, oscillatory motion about a specific point is supplied to that object. During this motion, velocity and acceleration values of the object are measured simultaneously with the force and torque values at the connection point. Mass properties of the object are c...
Development of de-icing and anti-icing solutions for aircraft on ground and analysis of their flow instability characteristics Körpe, Durmuş Sinan; Özgen, Serkan; Department of Aerospace Engineering (2008) In this thesis, development process of de-icing and anti-icing solutions and their flow instability characteristics are presented. In the beginning, the chemical additives in the solutions and their effects on the most critical physical properties of the solutions were investigated. Firstly, chemical additives were added to glycol and water mixtures at different weight ratios one by one in order to see their individual effects. Then, the changes in physical properties were observed when the chemicals were a...
Development of PDMS-based micromachining process for microfluidic reconfigurable antennas / Seyedpour Esmaeilzad, SeyedehNasim; Külah, Haluk; Topallı, Kağan; Department of Electrical and Electronics Engineering (2015) The objective of this thesis is to develop fabrication methods to implement microfluidic-based reconfigurable antennas. As the initial structure, a microfluidic based reconfigurable antenna is developed for transmitarrays, which consists of a multi-layered structure incorporating a microfluidic channel to confine liquid metal. The microfluidic channels are fabricated using soft lithography techniques where the channel material is PDMS. PDMS-to-glass and PDMS-to-PDMS bonding processes are optimized to achiev...
