    Swirl coaxial injector element characterization for booster engines

    Get PDF
    Recent hot fire testing at the Marshall Space Flight Center (MSFC) has indicated the swirl-coaxial element to be a viable candidate for the STBE injector. Plans are to test the current 40K lbf thrust injector at the higher chamber pressure and colder fuel temperature which are anticipated for STBE. A cold flow program to characterize the swirl coax element over a range of operating points was conducted. The results are presented and compared to the hot fire data. Predictions for compatibility, performance and stability are then presented for the uprated test conditions

    Existing peatland development and future uses for peat are described and evaluated in this report. Scenarios for future development of the study area peat industry are described in terms of employment, earnings, capital investment, and value of production. Forecasts of the potential impacts of peatland development on regional industry production, employment, earnings, and population are presented. These impacts are determined by using SIMLAB, an acronym for a regional socio-economic computer model developed at the University of Minnesota for quantitative analysis of the direct, indirect and induced socio-economic effects of events like peatland development.Land Economics/Use,
