ABSTRACT:
A turbomachine assembly comprising: an annular compression section; a casing formed by an outer annular shell (204) and an inner annular shell (206) secured inside the outer shell by means of a plurality of radial support arms (208); an annular combustion section housed inside the casing; and an annular turbine section. The air coming from the compression section presents rotary motion with an angle of inclination relative to a longitudinal axis (X-X) of the turbomachine, and the combustion section includes angular distribution means for determining air flow direction so as to impart on the gas leaving the combustion section rotary motion with an angle of inclination that is equal to or greater than the angle of inclination of the air leaving the compression section, said angular distribution means being formed by the support arms (208), each of which presents an angle of inclination relative to the longitudinal axis (X-X) of the turbomachine that is greater than or equal to the angle of inclination of the air leaving the compression section.
