Acoustics Research Engineer

Acoustics Research Engineer Mechanical Engineer V NASA Glenn Research Center Brook Park, Ohio HX5 is an award-winning provider of engineering, research and development, and technical services to clients such as NASA and the Department of Defense. Founded in 2004, HX5 is a fast-growing veteran- and woman-owned company with locations nationwide. HX5 at the NASA Glenn Research Center in Cleveland, Ohio is currently seeking a part-time temporary Acoustics Research Engineer with experience in the analysis of noise generated from transonic jet flows. The selected candidate will perform the following tasks: - Investigate how acoustic excitation parameters influence the generation, amplification, and suppression of guided jet waves (GJWs) in a Mach 0.95 jet. - Reproduce and validate reported GJW phenomena using the COMSOL Multiphysics software package. - Identify frequency ranges in which upstream-propagating GJWs are maximally amplified and those in which they are naturally suppressed. - Verify linear scaling and superposition behavior of the numerical model with respect to source strength. - Evaluate the use of source placement as a control parameter for enhancing or suppressing GJW modes. - Investigate whether phased or multiple-source configurations can suppress upstream propagating GJW modes. - Documenting, reporting, and presenting results clearly and concisely. Required Skills: - Exceptional knowledge and experience with the analysis of jet acoustics. - Specialized experience using COMSOL to evaluate guided jet wave physics. - Strong analytical skills for interpreting complex datasets from test campaigns. - Excellent written and verbal communication skills with a record of high-quality publications and presentations. - Proven ability to integrate effectively into multi-disciplinary research teams and collaborate with diverse stakeholders. - High motivation, creativity, and problem-solving ability. Other Desired Skills: - Familiarity with Federal regulations for aircraft noise emissions. - Familiarity with jet noise experimental measurements and analysis. - Familiarity with aircraft engine analysis and design.
