Solar Thermal Loading for an Aircraft Cabin

  1. Sep 23, 2010 #1
    I have been asked to estimate the thermal load (in Watts) of a small, commercial aircraft (ie, King Air B300, B350) sitting on a tarmac on a hot day due to solar irradiance. The solar irradiance specified is 1120 W/m^2, the total surface area of the fuselage is about 52.93 m^2, and the emissivity of the paint has been estimated as anywhere from 0.47 to 0.97. How do I get Watts? I've calculated the following but it seems too high:

    (1120)*(52.93/2)*.47 = 13,931 Watts....isn't this way too high?
