Within the scope of this thesis study, an optimization tool for the ballistic design of three-dimensional grains in solid propellant rocket motors is developed. The modeling of grain geometry and burnback analysis is performed analytically by using basic geometries like cylinder, cone, sphere, ellipsoid, prism and torus. For the internal ballistic analysis, a quasi-steady zero-dimensional flow solver is used. Genetic algorithms have been studied and implemented to the design process as an optimization algorithm. Lastly, the developed optimization tool is validated with the predesigned rocket motors.

Application of ultrasonic burning rate measurement method on closed bombs Mumcu, Berkan; Kurtuluş, Dilek Funda; Arkun, Uğur; Department of Aerospace Engineering (2013) In this thesis study, detailed information about solid rocket motors and ultrasonic burning rate measurement method is given. An experimental setup is prepared for applying the ultrasonic burning rate measurement method. Before performing the burning tests, some pre-tests are performed for affirming the ultrasonic sensor and obtaining some experimental coefficients. Two different types of propellants, which do not include aluminum, are produced for the burning tests. The first type of the propellants has tw...
Numerical burnback analysis of three dimensional solid propellant grains Ata, Yusuf; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2015) This study consists of developing of a three-dimensional grain burnback simulation with minimum distance method using STL (Standard Template Library) geometry output for accurate and efficient grain burnback analysis and internal ballistic solver for simulation and also prediction of solid rocket motor performance. In this work the, the new burnback simulation tool named F3DBT (Fast 3 Dimensional Burnback Tool) developed at the Propulsion System Design Department of Roketsan Missiles Industries Inc. and dev...
Ultrasonic measurement of solid propellant burning rates in closed bombs and subscale motors Atak, Özen; Yamalı, Cemil; Department of Mechanical Engineering (2016) In the scope of this thesis, applications of ultrasonic measurement method on closed bombs and test motors were investigated with various aluminized and nonaluminized propellants with the main target of evaluation of burning rates. Detailed comparison between conventional methods for solid propellant burning rate measurements such as strand burner, firing of subscale test motors and ultrasonic measurement was performed. Burning rate evaluation of eight propellant batches were determined by thirty three clos...
Analysis of grain burnback and international flow in solid propellant rocket motors in 3-dimensions Yıldırım, Cengizhan; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2007) In this thesis, Initial Value Problem of Level-set Method is applied to solid propellant combustion to find the grain burnback. For the performance prediction of the rocket motor, 0-D, 1-D or 3-D flow models are used depending on the type of thre grain configuration.
Service life assessment of solid rocket propellants considering random thermal and vibratory loads Yılmaz, Okan; Özgen, Gökhan Osman; Kuran, Bayındır; Department of Mechanical Engineering (2012) In this study, a detailed service life assessment procedure for solid propellant rockets under random environmental temperature and transportation loads is introduced. During storage and deployment of rocket motors, uncontrolled thermal environments and random vibratory loads due to transportation induce random stresses and strains in the propellant which provoke mechanical damage. In addition, structural capability degrades due to environmental conditions and induced stresses and strains as well as materia...
