Abstract
An engine assembly for an aircraft propulsion system includes a gas turbine engine, a gearbox, and a first drive shaft. The gas turbine engine includes an engine output shaft, an air intake, and a compressor. The air intake includes an air intake body forming an air inlet, an air outlet, and an air plenum extending between and connecting the air inlet and the air outlet. The air plenum extends circumferentially about the engine output shaft between and to a first circumferential end of the air intake and a second circumferential end of the air intake. The first circumferential end and the second circumferential end form a circumferential gap. The compressor is connected in fluid communication with the air intake. The gearbox includes a gear assembly operably connected to the engine output shaft. The first drive shaft is operably connected to the gear assembly. The first drive shaft extends through the circumferential gap.
