DOI: 10.1088/1361-6463/ab222d
Abstract: Thrust and current-voltage characteristics of pulsed cathodic arcs operating in vacuum and ambient air are presented and analyzed. In near vacuum conditions the thrust is proportional to the pulse duration, whereas in atmospheric pressure air… read more here.

DOI: 10.1115/1.4041697
Abstract: Propulsive capability of manta rays' flapping pectoral fins has inspired many to incorporate these fins as propulsive mechanisms for autonomous underwater vehicles. In particular, geometrical factors such as sweep angle have been postulated as being… read more here.
