Hi, I was wondering if anyone could give me an idea of the temperature on the leading edge of the wing or the nose of a mildly sonic aircraft? Should I just calculate the stagnation temperature and assume this was over the first plus and minus 5% of the wing?
Best regards
Mark

Probably a bit quick

High-reflectivity Paint
Because the Concorde moves faster than sound, the air pressure and friction (collision with air molecules) really heat up the plane. The temperature of the aircraft’s skin varies from 261 degrees Fahrenheit (127 degrees Celsius) at the nose to 196 F (91 C) at the tail. The walls of the cabin are warm to the touch. To help reflect and radiate this heat, the Concorde has a high-reflectivity white paint that is about twice as reflective as the white paint on other jets. The heat encountered by the Concorde causes the airframe to expand 7 inches (17.8 cm) in flight.
