Development of interior ballistic simulation software

Danış, Faik
In this study, an interior ballistic simulation program is constructed for solid propellant conventional guns. In accordance with this purpose, interior ballistic calculations are studied numerically and two numerical models are produced: zero dimensional model and one dimensional model. Zero dimensional model, which is based on lumped parameter approach, examines variation of ballistic parameters with ignition of propellant grains in order to find muzzle velocity. In one dimensional code, the problem is modeled as one dimensionally as inviscid flow and Roe approximate Riemann solver is used as solution technique. Both of the models can simulate real gas flow by introducing covolume based on Noble-Abel equation of state. The differences between numerical models are examined.


Ballistic design optimization of three-dimensional grains using genetic algorithms
Yücel, Osman; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2012)
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 algor...
Performance prediction of nozzleless solid propellant rocket motors
Özer, Ali Can; Özyörük, Yusuf; Department of Aerospace Engineering (2015)
Integral rocket ramjet (IRR) type propulsion systems have many advantages over conventional solid rocket motors when used in tactical missile systems. Nozzleless boosters are one of the applicable concept choices for the system [1]. During the design and development phase of solid propellant rocket motors, simulation and prediction of behavior of a given motor by numerical tools is important in terms of decreasing the development duration and costs. The present approach includes performance prediction of no...
Experimental analysis on the measurement of ballistic properties of solid propellants
Cuerdaneli, S.; Ak, M. A.; Ulaş, Abdullah (2007-06-16)
Ballistic properties of solid propellants play an important role in the performance of the solid propellant rocket motors. Therefore, ballistic properties of a likely propellant should be known and provided to the design engineers. In this study, a specific AP/HTPB composite solid propellant (SCP) was examined to obtain steady-state linear burning rates as a function of pressure and propellant initial temperature, temperature sensitivity, and pressure deflagration limit (PDL). In some tests micro-thermocoup...

Coşkun, Volkan; Sert, Cüneyt; Acar, Bülent (2019-06-14)
Development of a solver in order to estimate the material response of charring ablative materials which are utilized as thermal protection systems in space vehicles is presented. First, the governing equations for modeling transient thermal response of charring ablative materials and the adopted numerical solution schemes are reviewed. The governing equations include energy balance, pyrolysis kinetics and mass balance. Solution of the governing equations in conjunction with appropriate boundary condi...
Thermal radiation from solid propellant rocket motor plume
Özen, Güzide; Selçuk, Nevin; Department of Chemical Engineering (2015)
Radiation emitted from rocket plumes plays a significant role in quantifying infrared (IR) radiative signature which is essential for identification and tracking of rockets. Prediction of plume radiation necessitates simultaneous solution of conservation equations for mass, momentum, energy, chemical species and radiant energy to provide input data for the radiation code. This is carried out by a Computational Fluid Dynamics (CFD) solver. As CFD solvers are CPU time expensive, an accurate and CPU efficient ...
