 (skrăm′jĕt′)
n.
A ramjet airplane engine designed for hypersonic flight that burns fuel in the supersonic airstream produced by the plane.

(ˈskræmˌdʒɛt)
n
(Aeronautics)
a. a type of ramjet in which the forward motion of the craft forces oxygen to mix with fuel (usually hydrogen) at supersonic speeds within a duct in the engine
b. an aircraft powered by such an engine
c. (as modifier): scramjet technology.
[C20: from s(upersonic) + c(ombustion) + ramjet]
