Computational fluid analysis of G-12 parachute

Jesus Lucio Valles, University of Texas at El Paso


The main focus is on the Computational fluid interaction of the effect of parachutes in use on stresses and forces in the material. Constant research is being done to understand how air behaves when it interacts with parachutes. Due to the high turbulence and chaotic air behavioral, it is difficult to predict the behavior of the parachute. The stresses and pressure measurements are nearly impossible to take when in actual use. By simulating such problem in a computer software major advancement is made. The measurements are now taken and the behavior of the parachute is obtained. Rather than having to physically experiment and conduct these experiments, time and a large amount of money is saved.^ In this thesis problems are solved with the help of computer software. The main objective is to use example problems to learn how to use LS DYNA Pre-Post and Post Processor, and learn in order to work on problems of our own. The objective is to duplicate an army parachute and use results to create more efficient parachutes. LS DYNA only reads K files and K files are also covered in the report, these K files are automatically created when working on the Pre Post Processor. Projects covered are a beam problem as well as a cube problem.^ The combination of various computer software is used to solve parachute problems. The results are analyzed, interpreted and a conclusion is made. All scenarios are for actual parachutes. Parachutes include the G-12 a 64 foot diameter parachute, also included are the T-10 personal parachute. The T-10 parachute, is a 32 ft diameter parachute, all parachutes covered are those used by the ARMY.^
