NIAC proposal summary
(A)We propose to pressurize existing and proposed habitats of all sizes to Include Skylab-II, Cislunar habitats, cycler habitats, Inflatables (Bigelow) The ISS and Planetary orbital habitat’s with Xenon or other Binaries of Noble gasses to augment the propellant mass of SEP stages.This could enable a SLS 130 foot long LH2 propellant tank in LEO or a Skylab-II MAX and transfer to L-2 and beyond with AARM derived SEP stage docked to exceptional large habitats.
(B)We Propose to Augment existing and proposed habitats of all sizes to Include Skylab-II, Cislunar habitats, cycler habitats, Inflatables (Bigelow) The ISS and Planetary orbital habitat’s with Xenon or other Binaries of Noble gasses to augment the propellant mass of SEP stages By utilizing Xenon or Binary Noble gases in pressurized tanks co-located inside the habitat
Both (A)(B) may be done together or separately,in the case of crew arrival the habitat is pressurised with air and the Xenon tanks empty or full serve as radiation protection
(C)An ARRM derived SEP stage docks with the augmented habitat and uses SEP propellant transfer from the habitat, conversely, a SEP stage can transfer Noble gas propellant to the habitats tanks so that the habitat can serve as a SEP propellant fuel depot and transfer vehicle
(D) we propose to use existing chemical and physics simulation programs to model Noble gasses and their binaries as to their suitability as presserants to Cryogenic chemical propellants and to find a sweets spot with dual use as a SEP propellent(Hybrid Stage).
(E) If (D) fails then the Best chemical stage Noble Gas pressurizer(Neon?) would simply be transported after chemical stage exhaustion to the SEP stage for Mixing with Xenon.We propose to model this possibility
(F) We propose to model utilizing dual use Noble gasses to inflate an NIAD or inflatable atmospheric decelerator with Noble gasses for planetary probes and habitats and to then use the inflation gas to perform orbital maneuvers.Uranus with its tilted moon system would benefit from NIAD and use the augmented noble gas to maneuver from a polar insertion science orbit to a moon science orbit.Conversely, the Noble gas is not augmented but instead replaces the weight of the existing proposed inflatables gas generator.We call this system Xe-NIAD.
Neptune would benefit from the Xe-NIAD with orbit insertion and SEP/RTG and after a Triton probe EDL , uses Triton gravity and SEP to maneuver into polar orbit science mission
(F) We propose a Cryogenic Neon “battery” This would be charged at Launch from Earth and cooled with ZBO and/or Hybrid stage LH2 or LCH4 boil off during cruise.At cryogenic propellant depletion, the Neon would expand and power a electrical generator.The Neon could also power a cold gas thruster on a Triton lander during EDL
(G) Neon Helium Binaries could cool space telescope instruments and provide electrical power with the binary expansion ratio during boil off.Binary cold gas could provide thrust/station keeping to space telescopes(three uses)
(H)Cryogenic Neon could also provide power to a Triton lander and provide a dual use cold gas thruster for a Triton hopper mission
