Abstract At present, very few CubeSats have flown in space featuring propulsion systems. Of those that have, the literature is scattered, published in a variety of formats (conference proceedings, contractor websites, technical notes, and journal articles), and often not available for public release.

Aircraft Distributed Electric Propulsion Technologies—A Review
IEEE Transactions on Transportation Electrification, 2022Global transportation has shifted toward electromobility to achieve net-zero emission, and in the next few decades, commercial electric aircraft is likely to become a reality.

Electric/Hybrid-Electric Aircraft Propulsion Systems
Proceedings of the IEEE, 2021The idea of electric propulsion for transportation is not new; indeed, the first cars, nearly 200 years ago, were electric. However, our dependence on fossil fuels over the last 100 years is now being questioned, and as a global society, we are moving ...

Gradient Quasi‐Liquid Surface Enabled Self‐Propulsion of Highly Wetting Liquids
Advanced Functional Materials, 2021Self‐propulsion of highly wetting liquids is important in heat exchanger, air conditioning, and refrigeration systems. However, it is challenging to achieve such a spontaneous motion as these liquids tend to wet all the surfaces due to their ultralow ...

Full-scale simulation of self-propulsion for a free-running submarine
The Physics of Fluids, 2021It is important to predict the self-propulsion performance of full-scale marine vessels during the design stage. With the development of highperformance computational techniques, full-scale ship-free running simulations focused on self-propulsion ...

Publisher Summary This chapter describes the propulsion aspects that must be taken into account when discussing rocket propulsion systems. The modem ideas of rocket propulsion actually had their beginnings in the 1880s in the small Russian town of Kaluga, south of Moscow.
