The intellectual understanding of aerodynamics, as well as the use of this understanding in the design of flight vehicles, has grown exponentially during the twentieth-century. How much of this growth can be called “sci

While technology normally finds its way between competing firms (often surreptitiously), this period is interesting in that companies broadly encouraged technology transfer. Wartime mobilization brought both pressures

This paper explores a major aspect of the “invention
