A system for cooling a generator mounted in the tail-cone of an engine. The system comprises a fairing, which receives through an inlet thereof air from a bypass duct and directs the bypass air towards a cavity of the tail-cone for cooling the generator. The bypass air is then expelled through an outlet of a support strut positioned in fluid communication with the tail-cone cavity. The fairing inlet and the strut outlet are both positioned in a plane substantially perpendicular to a longitudinal plane of the engine. In this manner, circulation of the bypass air through the fairing, the tail-cone cavity, and the strut may be achieved. The bypass air directed through the fairing further enables cooling of service lines accommodated in the fairing. A lobe mixer is further used to direct the fairing and shield the latter from core exhaust.

Air cooling design for tail-cone generator installation

A fire detection switch for use in a fire detection circuit of a aircraft engine, having: a first resistor and a second resistor disposed in series between a common terminal and an alarm terminal; and a thermally-sensitive element having a different resistance at low temperature than at high temperature, the thermally-sensitive element disposed in series with the second resistor and in parallel with the first resistor.
