SUMMARYFirefly Thermal Engineers apply world-class simulation skills and expert knowledge of heat transfer to solve complex cross-discipline problems encountered during launch vehicle and spacecraft design, development, and operations. Intense thermal radiation, aero heating, cryogenics, and vacuum culminate in a complex thermal problem with a wide array of solutions. Thermal engineers will deconstruct these complex issues to ensure Firefly vehicles meet customer requirements and conform to external safety standards, while reducing margin and driving future evolution of the vehicle thermal systems.
