The separation mechanism is a critical device that transports and releases satellites during launch on-orbit. However, as become smaller more compact, the traditional belt-locking or pyrotechnic release cannot meet micro-nano satellite’s requirements. A novel kinematic system was designed, analyzed, experimentally verified to achieve non-interference non-pyrotechnic of from vehicle while mainta...

Understanding the charge-separation mechanism in organic photovoltaic cells (OPVs) could facilitate optimization of their overall efficiency. Here we report the time dependence of the separation of photogenerated electron hole pairs across the donor-acceptor heterojunction in OPV model systems. By tracking the modulation of the optical absorption due to the electric field generated between the ...

Shock-boundary layer interaction (SBLI) is a kind of problem which is frequently met in supersonic engine inlet flow and external flow. A detail study on mechanism of reduction of shock induced flow separation by MVG is carried out by high order implicit large eddy simulation (LES). To generate the fully developed turbulent flow, a series of turbulent profiles are given by previous DNS simulati...
