Question

The route the Concorde took is displayed below. ch 2 / Recherche Mach 2 Circuit de la boucle:1h 40 the circular region in which people on the ground hear the Concorde's sonic boom directly, not reflected from a layer in the atmo- sphere, is a function where h, the Concorde's altitude in kilometres, T, air temperature at ground level in degrees Kelvin, where degrees Kelvin is equal to degrees Celsius plus 273.15, and Ta, the vertical temperature gradient, i.e. the temperature drop in degrees Kelvin per kilometre. (a) Over the interval [50,300] kilometres for D and (0,5] degrees Kelvin per kilometre for Ta, with an air temperature on the ground of 30 deg degrees Celsius, plot the level curves (contour plot) in the (D, Ta) plane when the plane is at height h5,10, 15,20 kilometres. (b) Assume that the Concorde passes through the sonic barrier at an altitude of 16.8 km, with a vertical temperature gradient of 5 Kelvin per kilometer How far due north of the French coastline must the Concorde fly to ensure the radius of the sonic boom carpet does not reach the coast?
