Abstract
A powerplant assembly includes an engine, a turbocompressor, and an overspeed protection valve. The engine includes an air intake and an engine exhaust. The turbocompressor includes a compressor section, a turbine section, and a rotational assembly. The rotational assembly includes a turbocompressor shaft, a bladed compressor rotor of the compressor section, and a turbine rotor of the turbine section. The engine and the turbocompressor form a gas flow path. The gas flow path extends from the compressor section to the air intake, through the engine, and from the engine exhaust to the turbine section. The overspeed protection valve forms a portion of the gas flow path. The overspeed protection valve is positionable in an open state and a closed state.
