This article designs a high-efficiency electric propulsion system for industrial trucks, such as dumper trucks. design proposes using an alternative energy storage of green H<sub>2</sub> hydrogen to reduce emissions. determines the systems' technical and power requirements, starting with each vehicle's driving duty cycles. For this analysis, longitudinal dynamic model is created, wh...

This study considers the optimal control problem of maximizing the raise in the periapsis of a spacecraft orbit using continuous variable low-thrust propulsion. The dynamics of the spacecraft in the two-body system are modeled using Lagrange’s planetary equations with the classic orbit elements as the state variables. Control is provided via the propulsion thrust components in the radial and ci...

The harmful effects of gas emissions, resulting from the consumption fossil fuels, on environment continue to increase. In order reduce these effects, new regulations are implemented in field maritime and it is getting harder comply with regulations. fact that technological developments conventional propulsion systems come a head become insufficient especially when environmental factors taken i...
