Propulsion Aerodynamics Engineer

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 are seeking an experienced Propulsion Aerodynamics Engineer in Poway, CA. to provide technical leadership in integrating Turbofan, Turboprop, and Hybrid Electric engines into military aircraft. This role spans the full development lifecycle, including conceptual design, detailed design, and ground/flight testing. The position primarily focuses on propulsion aerodynamics across all GA-ASI aircraft programs, emphasizing subsonic and transonic flight regimes. This role is part of the Flight Technologies department in Poway, CA. (San Diego, CA.)

In addition to technical guidance, the successful candidate will support design reviews, flight test range safety board reviews, and other activities to ensure successful fulfillment of GA-ASI’s contractual obligations. The engineer will also stay informed of industry trends and advance propulsion-related design capabilities, including computational fluid dynamics (CFD) and wind tunnel testing.

DUTIES AND RESPONSIBILITIES:

• Provide technical leadership in propulsion aerodynamics for aircraft ranging from subsonic UAVs with extensive natural laminar flow (NLF) to transonic UAVs with shock-laden flows.
• Stay current with industry developments, including participation in events such as the AIAA Propulsion Aerodynamics Workshop.
• Maintain familiarity with SAE/AIR standards for aero engine integration into aircraft.
• Establish or refine standards for inlet diffusers, nozzles, ejectors, and other secondary flow paths, incorporating low observability (LO) features.
• Collaborate with the external aerodynamics team to improve thrust-drag bookkeeping practices.
• Develop methods to standardize error bar reporting for aerodynamic databases and reduced-order models (ROMs) based on rigorous statistical analysis and uncertainty quantification (UQ).
• Conduct analyses related to propulsion aerodynamics, such as creating aerodynamic databases for inlet/engine coffin plots using wind tunnel tests and/or CFD.
• Provide input on engine sizing for conceptual design of new aircraft concepts.
• Collaborate with other teams within the Flight Technologies department to enhance both new designs and existing GA aircraft.
• Present findings to internal stakeholders, external customers, and professional organizations.

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