General Atomics Aeronautical Systems, Inc. (GA-ASI), an affiliate of General Atomics, is a world leader in proven, reliable remotely piloted aircraft and tactical reconnaissance radars, as well as advanced high-resolution surveillance systems.

We have an exciting opportunity in San Diego, CA (Poway, CA) for an Aircraft Aero Performance and Propellers Engineer to contribute to the analysis of subsonic and transonic air vehicles, especially as it relates to the prediction of aerodynamics and aircraft performance. This engineer will be involved in the creation of aerodynamic databases derived from handbook methods, inviscid tools, wind tunnel, CFD, and flight testing. Specifically, the engineer will apply their knowledge of propeller theory, modeling, and CFD. This position is within the Flight Technologies department. Responsibilities include the execution and documentation of analyses and tests related to aerodynamics, CFD (computational fluid dynamics), and aircraft performance, aircraft sizing, tool development, the estimation of budgets and schedules, and interfacing with internal and external customers as necessary to present results and ensure work is completed appropriately.

DUTIES AND RESPONSIBILITIES:

• Responsibilities will include aerodynamic database development, aircraft performance analysis, mathematical modeling, aerodynamic predictions, simulation development and support, flight data analysis, and documentation.

• Plan, manage, and execute aerodynamic analyses using tools that range from handbook methods via inviscid tools all the way to Navier-Stokes CFD and associated meshing tools.

• Develop and maintain in-house analysis and design tools, perform mathematical modeling, and provide aerodynamic design support for new aircraft and modifications to existing aircraft.

• Support various tests including wind tunnel tests and flight tests, including reducing and analyzing the data after the test and documenting the results.

• Generate reports, specifications, memos, performance charts for flight manuals, and sketches of the obtained aerodynamic and performance results and present them verbally in meetings and phone conferences to all level employees and customers.

• Occasional travel to wind tunnels, flight test sites, customer sites, and conferences.

We recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply.

• Requires strong knowledge of aircraft performance, aircraft sizing, and aircraft stability.

• Requires familiarity with aerodynamic analysis tools that include inviscid tools, 2D airfoil codes (such as XFoil and MSES), and full Navier-Stokes CFD solvers and meshers.

• Requires thorough understanding of propeller theory, including analysis methods such as momentum actuator disk, blade element method (BEM).

• Requires experience with lower-order propeller/rotor/fan tools, such as XROTOR and DFDC.

• Requires experience with setting up, meshing, and running multiple methods and fidelities of propeller representations within CFD models.

• Beneficial if the candidate has tested propellers in a wind tunnel.

• Must have a sincere interest in airplanes.

• Requires solid programming knowledge (C, C++, Fortran, preferably Matlab).

• Must have an understanding of engineering concepts, principles, and theory and experience demonstrating the application of those concepts.

• Must possess the ability to understand new concepts quickly and apply them accurately throughout an evolving environment.

• Requires a strong and respectful communicator with excellent interpersonal skills.

• Must be able to work both independently and on a team.

• Ability to obtain and Maintain a DoD security clearance is required.

Desirable Qualifications:

• Track record of repaired geometries, completed meshes and analyses using Navier-Stokes CFD solvers and meshers (preferably Fluent, CCM+ and ANSA).

• Prior experience with aircraft flight testing and knowledge of flight dynamics, flight data analysis and interpretation, and development of data analysis tools.

• Turbofan exhaust nozzle/ejector design and NPSS modeling experience

• Pilot’s license.
