Optimisation of Energy Transfer in Reluctance Coil Guns: Application to Soccer Ball Launchers

open access: yesApplied Sciences, 2020
Reluctance coil guns are electromagnetic launchers having a good ratio of energy transmitted to actuator volume, making them a good choice for propelling objects with a limited actuator space. In this paper, we focus on an application, which is launching

Modal Analysis of a Discrete System in the Form of a Rocket Launcher Installed on a Motor Vehicle [PDF]

open access: yesProblemy Mechatroniki, 2016
A discrete model of an unguided rocket missile launcher installed on a motor vehicle was developed on the basis of a real assembly. The model is simplified to a vertical plane; it has four degrees of freedom and is adapted for a modal analysis.
