Understanding Side-wind Dynamics and Deciphering Ringsail Parachute DriftBy Kum Gwon Choe, Yu Mi Sin, Sol Song Pak, Ji Yong Ri, Jong Gil Pak
Abstract: The geometric complication caused by the "rings" and "sails" used to make the parachutist's canopy provides a considerable computationally problem, which is the focus of this paper's fluid–structure interaction (FSI) modeling of ringsail parachutes. Based on the sustained space-time FSI (SSTFSI) method, we have developed an FSI simulation of ringsail jumping devices. The FSI Geometric Smoothing Technique and the Homogenized Modeling of Geometric Porosity represent a pair of the above …

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 …
