Research included evaluation of 20 microclimate cooling options for metabolic heat removal and updating a previous report published by the U.S. Army. Each technology was evaluated by distilling them to their fundamental thermodynamic cycles and rating them at set mission profiles for anticipated operating conditions. Work included providing thermodynamic system modeling to the research team.Thesis research included the development of a hydrostatic bearing model, a bearing test facility,… Show more Research included evaluation of 20 microclimate cooling options for metabolic heat removal and updating a previous report published by the U.S. Army. Each technology was evaluated by distilling them to their fundamental thermodynamic cycles and rating them at set mission profiles for anticipated operating conditions. Work included providing thermodynamic system modeling to the research team.Thesis research included the development of a hydrostatic bearing model, a bearing test facility, and a set of test bearings that was used to demonstrate the feasibility of a hybrid cryocooler concept. Research concluded with helping to prototype the hybrid cryocooler. Show less
