Abstract
With a door seal for a gas turbine engine, a gap () existing between an axially symmetrical component () and an assembly formed by several segments () is sealed by seal doors (), which are held via retaining holes () at retaining bolts () on one of the components, the seal doors () being pressed against sealing edges () of the two components, with the sealing edges () being disposed at a certain distance from each other. The retaining bolts and holes are located outside the pressure surface (A) of the seal doors, formed between the two sealing edges, thus preventing cooling air losses via a gap remaining between the retaining bolts and bores.
