Claims7
An intake shield for use with a gas turbine engine air intake, in which means are provided for adjusting the height of the shield to facilitate its co-axial alignment with the engine intake, said shield comprising a wheeled structure containing a hollow chamber which locates over the engine intake so as to totally enclose the engine intake apart from an aperture through which the engine intake is inserted, said chamber having at least one wall which is formed with a plurality of flow passages so as to be porous to air but impervious to vortices and debris, and the dimensions of the chamber being such that, in use, the engine draws its air through the passages in said at least one wall which present a greater area for the flow of air than that of the engine intake.
An intake shield for use with a gas turbine engine air intake, said shield comprising a wheeled structure containing a hollow chamber which locates over the engine intake so as to totally enclose the engine intake apart from an aperture through which the engine intake is inserted, said chamber having at least one wall in which a part of the wall facing the engine intake is made of acoustic absorbing material and is formed with a plurality of flow passages so as to be porous to air but impervious to vortices and debris, and the dimensions of the chamber being such that, in use, the engine draws its air through the passages in said at least one wall which present a greater area for the flow of air than that of the engine intake.
