JSEG Rocket Propulsion Systems Analyst (Mid Level) with Security Clearance
Company: Bevilacqua Research Corp
Posted on: January 13, 2019
Job Description/Essential Functions: Bevilacqua Research Corporation (BRC) is a Service Disabled Veteran Owned, Small Business based in Huntsville, Alabama incorporated in 1992. BRC provides "best-value" technical and management solutions to a diverse government and commercial customer base in the following key business areas: test & evaluation, systems analysis & integration, security & intelligence, and R&D. The Engineering Services and Science Capability Augmentation (ESSCA) contract provides engineering, scientific and engineering technician support to NASA Marshall Space Flight Center (MSFC) in Huntsville, AL. Come join the team whose work is destined to have a long-range effect on future generations! This position is for a Rocket Propulsion Systems Analyst who will work both independently at times and in an integrated team performing analysis to support liquid and nuclear rocket propulsion systems. Responsibilities: * Performing steady-state power balance modeling and transient system analysis of liquid propellant rocket engine systems, both chemical and nuclear fission powered, using the Rocket Engine Transient Simulation (RocETS) and Numerical Propulsion System Simulation (NPSS) tools. * Using power balance tools to define engine subsystem performance requirements (propellant control hardware, turbomachinery, injector, and thrust chamber/nozzle) and to help optimize overall engine system performance. * Analyzing rocket engine thrust chamber performance by means ranging from textbook governing relations, to chemical equilibrium tools (typically Chemical Equilibrium with Applications, or Cequel), to analysis of regeneratively and/or radiatively cooled systems with the Two-Dimensional Kinetics (TDK) software tool. * Executing control volume flow analyses ranging from isothermal, incompressible flows, to chemically reacting compressible flows, to the flow of cryogens often in their two-phase region. Apply knowledge of various mechanisms of momentum loss and heat flow for these types of flows, especially the impact of chemistry on thermodynamic/physical properties in both core and boundary layer regions, heat flow in two-phase cryogenic flows, and the role of various boiling regimes in heat/mass transfer. * Attending technical interchange, project planning, design review and other appropriate meetings to maintain a current knowledge base of design, requirements, issues, action items, and resolution activities. Identify issues, pursue resolutions, and provide supporting analyses. Complete assigned action items. Analyze requirements and assess system risks. * Understanding customer objectives and product requirements. Document and deliver analytical results with recommendations for meeting system requirements. * Performing other duties as assigned. Minimum Requirements: * Degree in Engineering or related field from an ABET-accredited university is required. Typically, educational requirements are the equivalent of a Ph.D. with a minimum 4 years of experience; Masters with at least 8 years of experience, or a BS with at least 10 years of experience. * Experience with performing systems power balance analysis on propulsion designs is mandatory. * Basic knowledge of nuclear fission power reactor physics and neutronic deposition of power within reactor subassemblies is strongly desired including the ability to understand cooling requirements for reactor subassemblies for the purpose of interfacing traditional engine system assemblies (control valves, turbomachinery, nozzle regenerative cooling) with reactor cooling needs. * Proficiency with coding in an industry standard programming language such as Python is mandatory. * Experience with one, or more, of the following tools for execution of control volume fluid network analyses: Rocket Engine Transient Simulation (RocETS), Generalized Fluid System Simulation Program (GFSSP), and/or MSC/Easy5. * Proficiency with Microsoft Office products such as Power-Point, Excel, and Word is required. * Knowledge of the impact of environment on pressure and temperature transducer outputs for measurements in a liquid hydrogen propellant system, the systemic temperature measurement error associated with heat load through traditional and resistance thermocouple type sensors, and methods to estimate and correct such errors using co-located pressure measurements are pluses. * Knowledge of common sources of measurement error associated with pressure measurements to include common flow metering restrictions and "cavitating" meters is a plus. * Ability to perform spectral analysis of rocket engine test data streams (typically pressure and temperature sensor output) to identify sources of anomalous behaviors is desired. * Knowledge of the statistical/quantum mechanical underpinnings of dihydrogen and its nuclear spin states and the ability to apply this knowledge to maintenance of a NASA-developed thermodynamic property database for the parahydrogen nuclear spin state is a strong plus. * Excellent written and verbal communication skills are required. Other Job Information (if applicable): -- * Ability to perform spectral analysis of rocket engine test data streams (typically pressure and temperature sensor output) to identify sources of anomalous behaviors is desired.
