Microgravity Propellant Gauging Using Modal Analysis: Phase II
Project Description
The Modal Propellant Gauging (MPG) experiment is designed to assess the mass gauging resolution of a novel implementation of experimental modal analysis (EMA). The central objectives of the MPG experiment are to (1) record the modal response of a model propellant tank at different fill-levels under unsettled, microgravity conditions, and (2) record the modal response of the propellant tank during simulated propellant transfer. Phase II of the Modal Propellant Gauging (MPG) project will assess the gauging resolution of the MPG technique at low fill fractions for unsettled, sloshing propellant simulant. Phase II will utilize a full-fidelity propellant tank with flight heritage and will extend the gauging analysis to accommodate changes in tank pressure during low-gravity propellant transfer operations. This work is a continuation of previous flight testing under T0123 and T0147.
More »Anticipated Benefits
The ability to gauge the amount of propellant in fuel tanks in low-gravity is a critical technology, as it is the only way to verify the propellant quantity without having to settle the liquid via a propulsive maneuver. This technology will benefit the commercial industry and future NASA missions.
