ABSTRACT:
A gas turbine propulsion engine for aircraft of the type in which thrust is provided only from flow of exhaust gases or a combination of flow of exhaust gases and by-pass air, the engine having a cone-shaped spinner with a solid pointed tip portion and a main body portion. The tip portion has at least a surface made of a different material from the substantially rigid material of the main body portion, the at least surface of the tip portion being flexible relative to the body portion at operational rotations of the spinner whereby ice is automatically shed from the spinner due to cracks being developed at the bond between the tip portion and the main body portion. The cracks in the ice developed at the bond are propagated by the surface deflection of the remainder of the tip portion causing any accretion of ice thereon to shed from the remainder of the spinner.
