Various embodiments of the invention can include a portable power system with multiple power generation modes and mode based adjustable drag configuration. Embodiments of the invention include a system with an adjustable inlet ram air inlet, a ram air powered section (e.g. a ram air powered turbine with an adjustable ram air inlet), a fuel powered section, e.g., jet fuel powered auxiliary power unit, which is used when insufficient ram air is present or a power surge requires augmented power generation, and a generator section selectively coupled with the ram air powered section and the fuel powered section.
