Abstract: The invention is concerned with an improved individually replaceable insulation pack comprising a high temperature resistant thin flexible metallic sheet having a porous insulation blanket formed of interlaced ceramic fibers held against a side thereof and including a fine mesh of wire covering the surface of the blanket which is not adjacent to the sheet and holding the blanket against the sheet. The blanket does not contain a binder and is not bonded to the sheet.

Abstract: A turbine shaft and bearing assembly for a gas turbine is positionable as a unit in a turbine housing while providing means for lubrication of the associated bearings and means for communicating cooling fluid to the associated turbine wheel. The turbine shaft and bearing assembly which is the subject of this invention is applicable in one embodiment to a gasifier turbine housing or in another embodiment to a power turbine housing.

Abstract: The invention is concerned with an improvement in a modular gas turbine engine assembly comprising a tubular case, a gasifier module detachably attachable with a first end thereof adjacent a first end of said case and a power output module detachably attachable with a first end thereof adjacent a second end of said case, said case and said modules defining a partially walled off combustion-ducting section within said engine. The improvement comprises a plurality of individually replaceable insulation packs which provide heat insulation between the combustion-ducting section walls and each of said case, said gasifier module and said power output module. In another sense the invention comprises an improved individually replaceable insulating pack comprising a high temperature resistant metallic sheet having a porous insulation blanket and including a fine mesh of wire covering the surface of the blanket which is not adjacent to the sheet and holding the blanket against the sheet.

Abstract: An overload safety device in an output gear box of a high speed turbine engine protects the output gears and shaft system of the turbine against damage due to instantaneous high loads imposed on the turbine as, for example, high loads due to out-of-phase paralleling of a generator. The device comprises interleaved friction discs normally compressed together under a predetermined load by a plurality of spring-biased clamping bars. When the torque load on the friction discs exceeds a predetermined amount, the discs will separate axially against the clamping bars whereby the torque overload is alleviated.
