Bleed air duct leak detection system

摘要

A leak detector for an insulated duct carrying pressurized hot air comprises a cuff (10) secured over a circumferential cut in the insulation of the duct, thereby creating a reservoir of hot air which has leaked from the duct, a manifold (30) defining a conduit (34) therein in communication with the hot air reservoir and a cap (40) for securing heat sensitive wires (8) to manifold at the end of the conduit such that the hot air from the hot air reservoir impinges directly on the heat sensitive wires.
