What is the fuel burn rate for climb of a C-130J Hercules?
A rough estimation: for a mass of 60000 kg, the energy needed for that (1000 ft = 305 m) altitude change will be 60000 x 9,8 x 305 = 179 MJ. Jet fuel has a heating value of 44 MJ/kg, and if we assume a global conversion efficiency of –say– 7%, the fuel needed would be 179/(44 x 0,07) = 58 kg...
