a chassis comprising a cage formed by a grid of bars,
a nacelle fastened to the chassis and formed by a plurality of cowls,
a propulsion system seated in the nacelle and including a core enclosed in a casing and having a combustion chamber and a turbine provided with blades that are rotary about a longitudinal axis, a portion of the casing containing the turbine being seated in the cage,
a supply pipe configured to convey dihydrogen, winding inside the nacelle as far as a rear of the turbine, and having a radial step that passes through one of the cowls to reach an outside of the nacelle,
an injector rail seated in the nacelle, the injector rail fitted with injectors that enter the combustion chamber at a front of the turbine and having a radial step that passes through one of the cowls to reach the outside of the nacelle,
a bypass pipe fluidically connected between the two radial steps and arranged outside the nacelle, and
protection means comprising:
a protection plate arranged inside the cage in relation to the bars and extending between the turbine and the bypass pipe,
