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 …

Study on the Profile and Flow Field Variation of Parachute Coating by Seven-hole Probe MethodBy Kun Song Kim, Sun Ri, Sol Song Pak, Nam Song Pak, Kum Song Kim
Abstract: In general, the parachute test is a long test cycle, expensive, and difficult to measure with accuracy, which makes it a very laborious and time-consuming task. Therefore, attempts have been made to overcome this by using a parachute test stand or by simulation, but in our country, there is no numerical simulation of the parachute and there is no research on it. In this paper, the variation of the shape …
