Given: original project Orion https://en.m.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion) My idea is the addition of a centrifugal couch to regulate gravity to crew during the acceleration and deceleration phases of the trip. The Orion concept, for an interstellar ark concept, relies on an ablative pusher-plate system to act as a shock absorber and provide some relief to crew from g forces during the beginning and end phases of the trip. I want to add the centrifugal couch to this. Picture a steam locomotive. The track is the path the ark takes on its' journey. The steam in this metaphor is from the detonation, and the detonation force on the pusher plate pushes a ram that works to rotate an arm that rotates around a fixed point in line with the direction of travel. The arm is configured so that it rotates on an "axle" connected to other components that contains ark modules that are not as sensitive as biologicals to extreme g forces. There are thus multiple "arms" rotating in space, an even number of them, revolving counter to one another to negate possible yaw effects from rotation forces in space and vacuum. Similar to the steam locomotive with the buildup of steam pressure turning the wheels, the detonation in a Project Orion ark occurs at a point in time mechanically where the crew compartment attached to the end of the rotating arm in space achieves a constant gravity during rotation, and thus the rotating body translates fore and aft acceleration into centrifugal force that can simulate gravity in the crew compartment. I believe that the release in steam used to power a locomotive can roughly instruct a centrifugal couch concept that creates artificial gravity for crew and increases comfort during transition phases. The pusher plate would accept force from the detonation, and would relax once the detonation forces subsided. This ram would cushion forces for cargo, but the centrifugal couch I believe would further dampen those forces to increase survivability and comfort for crew. Currently, the concept would call for detonations every ten seconds for 30 days straight on both ends of the journey. The detonations for this timetable and this acceleration would yield 4 gees of force with each detonation for the crewed ark. I guess the question here is would the centrifugal couch concept relieve g force strain on the crew mechanically? Instead of whiplash and sleep deprivation every ten seconds for a month, is it possible to mechanically divert the forces into a rotary motion that solves a problem (whiplash, artificial gravity) and increases comfort? Or are we seriously talking about a 30 day medically induced coma so the crew can transition without becoming insane? I also have some ideas about rotary regulators for the concept that derive from analog, steampunk technology that would divert a small portion of the force of each detonation to regulate the rotary speed of each armature as a robust and reliable inherent design feature.
