In support of t ...http://www.ntis.gov/search/product.aspx?ABBR=N20120016509The advent of the commercial space launch industry and NASA's more recent resumption of operation of Stennis Space Center's large test facilities after thirty years of contractor control resulted in a need for a non-proprietary data acquisition syste ...http://www.ntis.gov/search/product.aspx?ABBR=N20130000303The small-scale broad area cooling (BAC) shield test panel represents a section of the cryogenic propellant storage and transfer ground test article, a flight-like cryogenic propellant storage tank. The test panel design includes an aluminum tank she ...http://www.ntis.gov/search/product.aspx?ABBR=N20130000537The present study details the high-power condensable propellant research being conducted at NASA Glenn Research Center. The gallium electromagnetic thruster is an ablative coaxial accelerator designed to operate at arc discharge currents in the range ...http://www.ntis.gov/search/product.aspx?ABBR=N20120018050A simulation framework based on the Memory-Mapped-Files technique was created to operate multiple numerical processes in locked time-steps and send I/O data synchronously across to one-another to simulate system-dynamics. This simulation scheme is cu ...http://www.ntis.gov/search/product.aspx?ABBR=N20120018049This Guide provides annual fuel cost estimates, rounded to the nearest $50, for each vehicle. The estimates are based on the assumptions that you travel 15,000 miles per year (55% under city driving conditions and 45% under highway conditions) and th ...http://www.ntis.gov/search/product.aspx?ABBR=PB2013106576This presentation covered an overview of AFRL's rocket propulsion laboratory and discussed hydrazine as a state-of-the-art rocket fuel, objectives for ionic liquids as bipropellant fuels, anion control of hypergolic activity, work on shorter ID times ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571738This study has investigated the feasibility of installing a gas generator-free turbine type power plant in the R3Y aircraft, using a circulating fuel reactor as a power source. Two variations of the cycle were considered. The split flow cycle bleeds ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131068544In-space propulsion often necessitates the use of a capillary liquid acquisition device (LAD) to assure that gas-free liquid propellant is available to support engine restarts in microgravity. If a capillary screen-channel device is chosen, then the ...http://www.ntis.gov/search/product.aspx?ABBR=N20130000453This effort addressed ignition and combustion of aluminum particles in different environments. The focus was on identifying quantifiable characteristics of aluminum ignition and combustion that are useful for development and validation of the respect ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571672A sub-model is developed to account for the drag and heat transfer enhancement resulting from deflagration-to-detonation (DDT) inducing obstacles commonly used in pulse detonation engines (PDE). The sub-model is incorporated as a source term in a tim ...http://www.ntis.gov/search/product.aspx?ABBR=N20120012911Project Themis is an in-house program within the Liquid Engines Branch of the Air Force Research Laboratory (AFRL). It focuses on investigation of liquid oxygen (LOX)/hydrocarbon high pressure combustion devices through subscale experimentation in co ...http://www.ntis.gov/search/product.aspx?ABBR=ADA572169
