Question

27 Concorde in Flight Constants The Concorde was a supersonic aircraft used for trans-Atlantic travel in the 1980s and 1990s, having a length of 61.8 m when sitting on the ground on a typical day when the temperature is 16.0 °C. The Concorde is primarily made of aluminum. In flight at twice the speed of sound, friction with the air warms the Concorde's skin and causes the aircraft to lengthen by 30.0 cm. (The passenger cabin is on rollers, so the airplane expands around the passenger cabin.) Take the coefficient of linear expansion for aluminum to be a 2.40 10-/oC Part A What is the temperature T of the Concorde's skin in flight? View Available Hint(s) T- oC

Answer 1

Change in temperature delta T = delta L/alpha L_0 = 30 times 10^-2/2.4 times 10^-5 times 61.8 = 202.26 degree c temperature of Concordes skin in flight = delta T + T_1 = 202.26 + 16 = 218.26 degree c
