Aerothermal Engineer

The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, is located midway between Baltimore and Washington, DC. We are seeking a highly motivated, creative programmer to join a dynamic diverse group providing superior mechanical and aeronautical engineering services and products to address the hard challenges for programs of national importance.



Job Summary: Predict aerothermal behavior of new hypersonic glide vehicles and scramjet missiles in endo-atmospheric flight conditions. Create innovative aerothermal predictions and advance numerical simulation capabilities.

Duties (Listed in order of importance with the estimated amount of time spent at each task):

  1. Use these numerical models to predict aerothermal response of hypersonic glide vehicles and scramjet missiles in endo-atmospheric flight conditions. Create innovative aerothermal methodologies using and improving current and new numerical simulation capabilities including CFD to capture relevant physics of interest with materials that are potentially ablating. (40%)
  2. Participate in efforts to experimentally characterize new thermal protection system materials at the laboratory level, wind tunnel and arc jet facilities to take advantage of new state of the art materials and analysis capabilities. Work with an experienced team to analyze and develop a new innovative hypersonic glide vehicle design ensuring optimal system trades. Support the vehicle through a series of flight tests. (30%)
  3. Close collaboration with structural analysts of high temperature ablating thermal protection materials in non-equilibrium flow conditions with coupled thermal-structural nonlinear and micromechanical analyses. (20%)
  4. Document results in technical memoranda and papers, present findings to government agencies, flight test mission planners, relevant professional publications and conferences. (10%)


Note: This job summary and listing of duties is for the purpose of describing the position and its essential functions at time of hire and may change over time.

Required Qualifications:
