The maintenance assembly, for workers to perform maintenance activities within a gas turbine engine, is capable of being arranged within a cavity, generally around a combustor, accessible from a manhole of the gas turbine engine. The maintenance assembly includes a platform, and an inflatable member cooperatively configured to the platform. The inflatable member is at a normal condition, when placed outside of the cavity, being at a deflated position and is at a working condition, when arranged within the cavity, being at inflated position so as to accommodate a shape coordinating the cavity in such a manner that the platform is advance within the cavity up to a predetermined level to enable the workers on the platform to reach at a predetermined position within the cavity to perform the maintenance activities.

1. A maintenance assembly configured for workers to perform maintenance activities within a gas turbine engine having a cavity, combustor, rotor and manhole, the maintenance assembly configured to be arranged within the cavity, generally around the combustor, and accessible from the manhole, the maintenance assembly comprising: a first platform and a second platform respectively configured to carry the workers;a u-shaped inflatable member configured to support the platforms, wherein the inflatable member has a first top-most surface and a second top-most surface, wherein the first platform is on the first top-most surface and the second platform is on the second top-most surface; andwherein the top-most surfaces are substantially parallel and completely separated from each other by the rotor when the inflatable member is inflated in the cavity; and wherein the inflatable member, when arranged within the cavity and inflated, has a bottom wall that matches a shape of the cavity in such a manner that the platforms are advanced upward into a horizontal position within the cavity up to a predetermined level to enable the workers to stand on the platforms to reach a predetermined position within the cavity to perform the maintenance activities within the gas turbine engine. 2. The maintenance assembly as claimed in claim 1, wherein the platforms are made of a wood material. 3. The maintenance assembly as claimed in claim 1, wherein the platforms are adapted to be advanced up to the predetermined position, which is at least up to a lower half position of the cavity. 4. The maintenance assembly as claimed in claim 1, wherein the inflatable member supports the platforms from below the platforms. 5. The maintenance assembly as claimed in claim 1, wherein the inflatable member when inflated is adapted to match a shape of the combustor of the gas turbine engine. 6. The maintenance assembly as claimed in claim 1 comprising: an inflating source configured to inflate the inflatable member. 7. The maintenance assembly as claimed in claim 6, wherein the inflating source is adapted to be disposed at an area outside of the cavity, the inflating source disposed at the area outside of the cavity is fluidically connected to inflate the inflatable member within the cavity. 8. The maintenance assembly as claimed in claim 6, wherein the inflating source is one of a pneumatic or hydraulic inflating source. 9. The maintenance assembly as claimed in claim 1, wherein the platforms are made of a laminate material. 10. The maintenance assembly as claimed in claim 1, wherein each of said platforms is a one-piece structure adapted to be advanced to a working position.
