WebNov 1, 2016 · Spitfire radiators were designed to use Meredith effect as well, although clearly not so efficiently as in the P51. However, that doesn't apply to a ducted fan. Perhaps the most efficient way to get the optimum thrust from a ducted fan is to have some variation in the inlet and exhaust areas, although weight and complexity probably rules it out. http://www.rcex.cz/kestazeni/EDF_THR3.pdf
