Mounting for gas turbine powerplant

A mounting for a gas turbine powerplant which comprises an inner annular casing containing a gas turbine engine, an outer annular casing surrounding the inner casing, a compressor connected to be driven by the engine and adapted to drive air through an annular duct defined between the casings, and a thrust reverser means at the outer casing for reversing the flow therethrough;

• the mounting comprising front and rear structural means arranged respectively at a front and rear location of the powerplant for supporting the powerplant laterally on a support situated at one side of the powerplant and radially outside the outer casing, tie means at said one side of the powerplant and connected obliquely to the axis of the powerplant between the inner casing at said front location and said support at said rear location, second tie means at a side of the powerplant opposite to said one side and connected obliquely to the axis of the powerplant between the inner casing at said front location and the outer casing at said rear location such that the axes of said first and second tie means at said front location intersect the axis of said gas turbine in substantially the plane of said front structural means, and means supporting said reverser means at the outer casing rearwardly of said rear location.
