A turbojet having an air intake case including radial arms between an outer annular structure and an inner central structure, and a deicing unit configured to deice the radial arms by microwaves and located in the central structure. The deicing unit has a microwave generator and a transmitting element configured to transmit energy and including an inside annular waveguide located inside of the central structure. An energy distributing element configured to eliminate ice is coupled with the transmitting element by a coupling element. The radial arms are made from a dielectric composite material.

Turbojet equipped with a deicing system on the intake case

A casing structural arm of a turbo-engine is fixed between an external ferrule and a hub of the casing and is formed as a composite material. The arm has one leading edge, one trailing edge, one radially external edge and one radially internal edge. These four edges define the four corners of the arm and securing of the arm to the ferrule and said hub is ensured by two pairs of linking braces respectively secured to the four corners of the arm.
