Facing the Heat Barrier "The 2nd law of thermodynamicsThis volume from The NASA History Series presents an overview of the science of hypersonics, the study of flight at speeds at which the physics of flows is dominated by aerodynamic heating. The survey begins during the years immediately following World War II, with the first steps in hypersonic research: the development of missile nose cones and the X 15; the earliest concepts of hypersonic propulsion; and the origin of the scramjet engine. Next, it
