Title:
CONTROL DEVICE FOR ROCKET
Document Type and Number:
WIPO Patent Application WO/2015/182456
Kind Code:
A1
Abstract:
 To drop a discarded item, such as a discarded nth-stage rocket or a single-stage rocket of which the engine has stopped, into a safe area while consuming as much carried fuel as possible to improve launch capability. The flight path of a two-stage rocket (1) is periodically predicted during flight, and the predicted drop point when a first-stage rocket (11) or a fairing (15) is separated and discarded is periodically predicted from a second-stage rocket (13) at each passing scheduled point in the predicted flight path. As long as there is a passing scheduled point such that the predicted drop points of the first-stage rocket (11) and the fairing (15) are both within the safe area, a process is periodically performed to designate the passing scheduled point furthest from the launch location of the two-stage rocket (1) as the separate-and-discard point of the first-stage rocket (11), and when the two-stage rocket (1) reaches this separate-and-discard point, the first-stage rocket (11) or the fairing (15) is separated and discarded.
