Modeling and Dynamic Analysis of a Rocket Towed Net System

doi:10.3969/j.issn.1000-1093.2019.09.009

Abstract

Abstract: The complex dynamical behaviors of rocket-towed net system are analyzed for system design. A three-dimensional model consisting of a rigid rocket model and a lumped mass net model is built based on the aerodynamics theory. The rocket towed net system model is solved by the fourth-order Runge-Kutta method in simulation. The proposed lumped mass model is compared with a rigid multibody model, and the flight dynamics characteristics of rocket towed net system are studied by analyzing the center of mass trajectory, velocity, and pitch angle of rocket in the experimental results. The flying test of an experimental system prototype was conducted. Simulated and experimental results show that the desployed distance accuracy of rocket towed net system is about 90% of the system length. Key

Key words: rockettowednetsystem, multiplebodydynamics, lumpedmassmodel, flyingtest
