Definition of Impact Angle and Impact Angle Control Law Against Maneuvering Target
Journal of the Korean Society for Aeronautical & Space Sciences, 2015 In this paper, a guidance law for intercepting maneuvering target with a desired impact angle is proposed. The proposed guidance law is modified from the optimal impact angle control law for a fixed target and given by a biased PN law with the impact angle control term in addition to the conventional PN law.

Bezier-curve Navigation Guidance for Impact Time and Angle Control [PDF]
INCAS Bulletin, 2018 This paper addresses a novel impact time and angle control guidance law using a Bézier curve. The 2nd order Bézier curve consists of one control point and two boundary points; initial point P0, middle point P1 and end point P2.

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.

Impact angle control of interplanetary shock geoeffectiveness [PDF]
Journal of Geophysical Research: Space Physics, 2014 AbstractWe use Open Geospace General Circulation Model global MHD simulations to study the nightside magnetospheric, magnetotail, and ionospheric responses to interplanetary (IP) fast forward shocks. Three cases are presented in this study: two inclined oblique shocks, hereafter IOS‐1 and IOS‐2, where the latter has a Mach number twice stronger than ...
