Summer 2027 - Flight Sciences - Propulsion Collegiate Intern
About The Position
The Propulsion Analysis team develops and maintains analytical methods used to predict, evaluate, and optimize aircraft propulsion system. The group's activities include engine performance modeling, cycle analysis, transient engine behavior, engine starting characteristics, inlet distortion and recovery, nozzle performance, thrust reverser performance, and compliance with regulatory requirements associated with aircraft propulsion systems. A key focus area is the development of advanced cycle analysis and off-design simulation capabilities used to evaluate propulsion system behavior across a wide range of operating conditions. The team develops analytical tools, improves modeling methodologies, and performs trade studies supporting both existing aircraft programs and future technology development initiatives. The organization collaborates closely with Aircraft Performance, Powerplant Integration, Flight Sciences, Aerodynamics, and Systems Engineering teams to ensure successful integration of propulsion technologies into Gulfstream aircraft. The selected student will gain hands-on experience in engine cycle analysis, propulsion system modeling, aircraft performance evaluation, advanced simulation techniques, and data-driven engineering decision making while contributing to active engineering projects.
