Scaling trajectories in civil aircraft (1913–1997) [PDF]

open access: yesResearch Policy, 2000
Using entropy statistics we analyse scaling patterns in terms of changes in the ratios among product characteristics of 143 designs in civil aircraft. Two allegedly dominant designs, the piston propeller DC3 and the turbofan Boeing 707, are shown to have triggered a scaling trajectory at the level of the respective firms.
