A micro-auxiliary power unit for supplying electric power to a vehicle includes a thermal resistant enclosure having an intake duct for receiving air, and a source of fuel. A fuel valve is fluidly coupled from the enclosure, and the fuel valve is movable between an opened position and a closed position. The micro-auxiliary power unit includes a Wankel engine to drive an output shaft and a starter-generator coupled to the output shaft to generate electric power. The micro-auxiliary power unit includes a system that has at least one sensor disposed within the enclosure that observes a condition of the enclosure and generates sensor signals, and a controller having a processor that receives the sensor signals, determines the presence of a thermal event within the enclosure and based on the determination, outputs one or more control signals to the fuel valve to move the fuel valve to the closed position.

Eductor systems and methods improve eduction by increasing swirl. An eductor housing defines a primary plenum channeling a flow stream from an inlet opening to an exit opening, and defines a secondary plenum separated from the primary plenum and channeling another flow stream from a duct inlet to exit slots. A gas flow stream is delivered into the eductor housing and is directed through the exit opening so that the gas flow stream educes the flow stream through the inlet opening and the exit opening. The second flow stream is delivered to the secondary plenum through a duct connected at an angle to induce a swirl in the secondary plenum to effect a static pressure reduction at the exit opening that draws the flow stream from the inlet opening through the exit opening.
