Fluid-Structure Interaction Simulation of Parachute by Eulerian-Lagrangian penalty methodBy Pak Sol Song, Hyong Gyu Jon, Kum Kwon Choe, Kwang Ho Kim, Jong Dok Ri
Abstract: In general, modeling and simulation of a model consisting of fluid and solid combinations has been considered difficult, and it has become impossible in terms of computer dependencies and accuracy to be analyzed by Fluent or other programs. The parachute evaluation process, which is historically based on a large amount of experimental data, necessitates many falling experiments. These tests can be costly and time-consuming, and they don't always allow for …

Improving Parachute Efficiency: The Function of LS- Dyna in Fluid-structure Interaction SimulationBy Chang Kim, Kun Song Kim, Sol Song Pak, Kum Gwon Choe, Hyong Gyu Jon
Abstract: As an accompaniment to assessment of DGA Aeronautical Systems created a simulation and model-building capability to gain a better understanding of the parachute dynamic behavior and to maximize the parachute systems flight tests. This work reports on the latest developments in Arbitrary Lagrangian mathematical (ALE) methods for analyzing the properties of the quasi-steady state descent phases and canopy inflation. Thus far, none of the simulations of the endless mass type …
