Abstract
A method for controlling the acceleration of a vehicle (10) reentering the sensible atmosphere, comprising executing a lofting translational rocket burn at an altitude of greater than about 40 km whereby the vehicle (10) reenters the sensible atmosphere at a maximum accelerative force of less than 4 g.
Claims13
A method for controlling the acceleration of a vehicle reentering the sensible atmosphere, comprising executing a lofting translational rocket burn after achieving apogee and at an altitude of greater than about 40 km whereby the vehicle reenters the sensible atmosphere at a maximum accelerative force of less than 4 g.
A method for controlling the acceleration of a vehicle reentering the sensible atmosphere, comprising executing a power dive rocket burn after entry of the vehicle into the sensible atmosphere whereby the vehicle reenters the sensible atmosphere at a maximum accelerative force of less than 4 g.
A method for increasing the acceleration of a vehicle reentering the sensible atmosphere, comprising initiating a downward translational rocket bum after achieving apogee and pore to reentering the sensible atmosphere so as to increase the maximum decelerative drag force imposed upon the vehicle during reentry.
A method for increasing the deceleration of a vehicle reentering the sensible atmosphere, comprising executing an upward translational rocket burn after reentering the sensible atmosphere so as to augment the decelerative drag force imposed upon the vehicle during reentry.
A method for extending the period of minimized dynamic pressure observed at apogee by a vehicle traveling proximate the edge of the sensible atmosphere, comprising executing a translational rocket burn through apogee wherein the thrust of the bum is sufficient to substantially counterbalance the downward accelerative force of gravity and thereby extend the period of minimized dynamic pressure observed at apogee.
