The Wright model B:
The Wright Model B was a 1910 plane developed by the Wright Brothers.1
According to Wikipedia2:
We use the range 363—567 kg, since we do not know at what weight in that range the relevant speeds were measured.
From Wikipedia, we have3:
From these we can calculate:
Energy use per second
= power of engine x 1/efficiency in converting energy to engine power
= 26kJ/s / .15—26kJ/s / .30
= 86.6—173 kJ/s
Wikipedia gives us4:
We use the cruise speed, as it seems more likely to represent speed achieved with the energy usages reported.
We now have (from above):
Thus, on average each second the plane flies 17.9m and uses 86.6—173 kJ, for 0.10—0.21m/kJ.
This gives us a range of 0.036 – 0.12 kg.m/J
