A Real-Time 6DOF Computational Model to Simulate Ram-Air Parachute Dynamics

Abstract

Abstract-Computer simulations are used in many disciplines as a methodology of mimicking behaviors of a physical system or a process. In our study we have developed a real-time six degree-of-freedom (6DOF), computational model that can replicate the dynamics of a ram-air parachute system which is the design of parachute that is widely used by the militaries worldwide for parachute jumps. The proposed model is expected to be adapted in to a real-time visual simulator which would be used to train parachute jumpers. A statistical evaluation of the proposed model is done using a dataset taken from NASA ram-air parachute wind tunnel test.

Passivity‐based control laws for an unmanned powered parachute aircraft

“…The values of the model parameters are shown in Table 1. These parameters were obtained from real aerial platforms [5,7].…”

“…Moreover, in Li et al [6] a mathematical model and an energy-based control law are designed for a PPUAV. In Gunasinghe [7], the authors propose a six-degree of freedom (DOF) model of a parachute system with which they calculate its position and orientation in a three-dimensional space. The parachute and the load it carries are considered as a single system, but the air turbulence is not modeled.…”
