Liquid hydrogen is used extensively by NASA to support cryogenic rocket testing. In addition, there are many commercial applications in which delivery and use of cryogenic hydrogen is more economical than gaseous hydrogen. Unfortunately, loss of hydrogen resulting from boiloff can both increase the cost of the end product and create safety concerns. Sustainable Innovations and its teammates, Th ...

The process of aircraft design requires the integration of data from individual analysis of aerodynamic, structural, thermal, and behavioral properties of a flight vehicle. At present, there is no simple way to integrate the results of the analyses early in the design process. Aurora Flight Sciences and the Massachusetts Institute of Technology Aerospace Computational Design Laboratory propose to ...

Computational tools that accurately predict the performance of electric propulsion devices are highly desirable by NASA and the broader electric propulsion community. Large investments in running the long duration test programs (> 20 kHrs) at NASA GRC can be reduced with computer models and allow more focus on exploring the NEXT ion thruster design for future space missions. The current state of e ...

The innovation proposed here is a high performance, high fidelity simulation capability to enable accurate, fast and robust simulation of unsteady turbulent, reacting flows involving cryogenic propellants (such as LOX/LH2 and LOX/LCH4). The key features of this proposed capability are: (a) Hybrid RANS-LES (HRLES) methodology, and (b) flamelet modeling for turbulent combustion incorporated in a pr ...

TSRCo and CU are developing a framework to quantify and predict crew performance in various spacecraft designs in the context of the design process. The framework utilizes an elemental resource breakdown approach to relate the crew, the spacecraft design, and operations. The elements identified in the breakdown correspond to existing measures currently used in the physiological, cognitive, and ps ...
