AN ANALYTICAL MODEL AND A COMPUTER CODE FOR THE DETAILED SIMULATION OF THREE-PHASE FLOWS IN LIQUID ROCKET THRUST CHAMBERS IS PROPOSED. THE MODEL DESCRIBES BEHAVIOR OF THE LIQUID, DISPERSED AND GASEOUS PHASES IN A MOST EFFICIENT FORM. THE CONTINOUS GAS-PHASE FLOW AND COMBUSTION ARE DESCRIBED IN EULERIAN COORDINATES; THE SPRAY FLOW, DROPLET EVAPORATION AND COMBUSTION PROCESSES ARE SIMULATED IN A GRI ...

NASA seeks intelligent monitoring and control methods to significantly extend the life and improve the safety of hybrid-electric propulsion, all-electric propulsion, and other applications where energy storage sources are used, such as in satellites and aerospace aircrafts. Lithium-based batteries are increasingly being used in many aerospace applications due to their superior energy and power den ...

Research in Flight is proposing to develop a fundamentally new, lower order, high fidelity solution approach for the aerodynamic analysis required for engine integration studies. This new approach is based on a new tool known as Flightstream. Flightstream is a surface vorticity based solver which uses an unstructured surface geometry, and a correlation for skin friction which is based on the sur ...

CU Aerospace (CUA) and the University of Michigan (UM) propose the development of the Cycle Automated Mass Flow (CAMFlow) system for reliable and well-regulated flow control. CAMFlow uses an innovative control scheme that enables stable operation using only Boolean valve states, even for the low flow rates necessary for sub-kilowatt Hall effect thrusters. This methodology removes system complexity ...

This Phase I proposal is submitted to verify the materials and process engineering of the space environment stable, multifunctional Plasma Sprayable conductive thermal control material system (TCMS) that can be applied to space hardware and can enables the hardware to carry higher leakage current through co doping process engineering for the high electrical conductivity. An innovative space enviro ...

Nuclear Thermal Propulsion (NTP) has been identified as a critical technology needed for human missions to Mars due to its increased specific impulse (Isp) as compared to traditional chemical propulsion systems. To achieve this high Isp, NTP reactors must operate at extremely high temperatures (i.e., >2400K) for long periods of time. However, many of the best materials for some reactor component ...
