Development of Urine Receptacle Assembly for the Crew Exploration Vehicle | CU Experts

<div class="htmlview paragraph">The Urine Receptacle Assembly (URA) initially was developed for Apollo as a primary means of urine collection. The aluminum housing with stainless steel honeycomb insert provided all male crewmembers with a non-invasive means of micturating into a urine capturing device and then venting to space. The performance of the URA was a substantial improvement over previous devices but its performance was not well understood.</div>; <div class="htmlview paragraph">The Crew Exploration Vehicle (CEV) program is exploring the URA as a contingency liquid waste management system for the vehicle. URA improvements are required to meet CEV requirements, including consumables minimization, flow performance, acceptable hygiene standards, crew comfort, and female crewmember capability.</div>; <div class="htmlview paragraph">This paper presents the results of a historical review of URA performance during the Apollo program, recent URA performance tests on the reduced gravity aircraft under varying flow conditions, and a proposed development plan for the URA to meet CEV needs.</div>
