The applicability of MFD thrusters to satellite power systems [PDF]
, 1980 The high power self field MPD thruster uses electromagnetic forces rather than electrostatic to accelerate a neutral plasma. The most attractive application of MPD thrusters to satellite power systems is in the area of electric propulsion for a cargo ...

The Effect of Chemical Reactivity on the Formation of Gaseous Oblique Detonation Waves
Aerospace, 2019 High-fidelity numerical simulations using a Graphics Processing Unit (GPU)-based solver are performed to investigate oblique detonations induced by a two-dimensional, semi-infinite wedge using an idealized model with the reactive Euler equations coupled ...

A new propulsion concept for high propulsive hydrodynamic efficiency
Ocean Engineering, 2022 A novel marine propulsor concept is presented for high hydrodynamic efficiency. Optimum performance is sought by thrust-producing counter-flapping foils cyclically oscillating along a closed trajectory. The thrusting device exhibits low propulsion loading and low viscous losses.
