Abstract

AIRCRAFT PROPULSION SYSTEM COMPRISING A TURBOMACHINE, A MOUNTING MAST, AND MEANS FOR ATTACHING THE TURBOMACHINE TO THE MOUNTING MAST. The invention relates to an aircraft propulsion system (100) comprising a turbomachine (102) having a front casing (103) with a rear face (103a) and a rear casing (105), a mooring mast (104) with a front portion (106a) to which a rear fitting (108) is attached, an arch (152) fixed to the rear fitting (108) and the rear casing (105), and on either side of the vertical median plane (P), three port / starboard connecting rods (155a-c, 157a-b) where each connecting rod is fixed between the rear face (103a) of the front casing (103) and the arch (152), where the three port connecting rods (155a-c) converge in a port convergence zone (161) at the level of the arch (152) and where the three starboard connecting rods (157a-b) converge in a starboard convergence zone at the level of the arch (152).
