ABSTRACT:
A connection device is disclosed for connecting a burner ring or flame holder made of a composite material and having a "V"-shaped cross-section, to an afterburner chamber duct of a turbojet engine. The connecting device has a cylindrical portion and a trapezoidal portion. The cylindrical portion extends through hollow projections formed from the composite ring material and extending from the ring in an upstream direction. The converging, opposite sides of the trapezoidal portion bear against inner surfaces of the converging flanges forming the "V" cross-section of the ring. The cylindrical portion is then attached to the afterburner duct via a link-bar mechanism.
