A spinner mounting at least one propeller hub and having a blade platform for each hub formed on the spinner body formed from a thermal insulating material capable of withstanding exhaust gasses. The platform is formed in a shape that presents an aerodynamic surface in the direction of travel of the system, preferably at a predetermined effective blade angle so as to act in concert with the blade and the gas path to minimize drag or to optimize thrust. The system may include two sets of propeller blades, and each includes a spinner and blade platform.
