Self-propulsion on liquid surfaces
Current Opinion in Colloid & Interface Science, 2014Abstract Surface tension gradients are at the origin of the self-motion and deformation of millimeter-sized floating objects. For (quasi-)non-deformable systems, like solids and gels, the motion-mode is mainly controlled by the shape of the object and by the way the surface active propellant is released on the surrounding surface.

Liquid Propulsion Turbomachinery Model Testing
SAE Technical Paper Series, 1992<div class="htmlview paragraph">For the past few years an extensive experimental program to understand the fluid dynamics of the Space Shuttle Main Engine hot gas manifold has been in progress at Marshall Space Flight Center (MSFC). This program includes models of the Phase II and II+ manifolds for each of the air and water flow facilities, as ...

Ionic Liquid Propellants: Future Fuels for Space Propulsion
Chemistry – A European Journal, 2013AbstractUse of green propellants is a trend for future space propulsion. Hypergolic ionic liquid propellants, which are environmentally‐benign while exhibiting energetic performances comparable to hydrazine, have shown great potential to meet the requirements of developing nontoxic high‐performance propellant formulations for space propulsion ...

Liquid resistance in underwater laser propulsion
Applied OpticsTo investigate liquid resistance in underwater laser propulsion, we conducted underwater propulsion experiments with cylindrical titanium targets of identical mass but varying propulsion areas through high-speed photography. An analytical formula was derived to elucidate the relationship among the kinetic energy of the target, the energy of the bubble ...
