Guidance law with impact time and impact angle constraints
Chinese Journal of Aeronautics, 2013 AbstractA novel closed-form guidance law with impact time and impact angle constraints is proposed for salvo attack of anti-ship missiles, which employs missile’s normal acceleration (not jerk) as the control command directly. Firstly, the impact time control problem is formulated as tracking the designated time-to-go (the difference between the ...

Impact of wastewater fouling on contact angle
Biofouling, 2009 Capillary dependent systems are highly influenced by surface fouling and may degrade as material surface properties change. In anticipation of a spacecraft microgravity fluids management system exposed to highly variable wetting conditions, the impact of urine wastewater fouling on capillary contact angle was examined.
