Abstract:
1. An exhaust assembly for producing rotational torque about a principal axis of a mass ejection drive system, said exhaust assembly comprising: a plurality of vanes suitably configured to at least partially intrude into a ejecta stream produced by the mass ejection drive system in order to produce rotational torque about the principal axis of the mass ejection drive system; said vanes configured to selectively disengage intrusion into said ejecta stream in order to substantially cease production of torque forces about the principal axis of the mass ejection drive system; a plurality of tailfins operatively coupled to the vanes, wherein said tailfins are suitably configured to selectively deploy from at least partially stowed positions in response to dispositional intrusion of said vanes with respect to said ejecta stream; and a housing having a vane recess suitably configured to receive one of the vanes, to lock the one vane in a position that at least partially engages the ejecta stream, and further suitably configured to allow unlocking and rotation of the one vane so that the one vane at least partially disengages from the ejecta stream.
