If the local speed of the aerofoil relative to the air were Mach 1 , the temperature of the local section would be around 1.2 times ambient temperature. Hub Mach number is obviously lower than tip Mach number, and conduction through the prop would tend to reduce temperature gradient along its length. So I imagine the answer would be no more than 5 to 10% above ambient (absolute temperature). Hope this helps, unless someone can come up with a definitive answer. Gerald Wilson.
