A hypersonic scramjet engine comprising:

• (a) an inlet having an inclined upper wall and having an aft portion;
• (b) a combustor serially connected to said aft portion of said inlet, said combustor having a top portion;
• (c) an exhaust nozzle serially connected to said combustor;
• and
• (d) a plurality of horizontally-spaced-apart fuel injectors disposed in, and connected to said top portion of, said combustor, each said fuel injector including a housing having a generally horizontal top wall, an inclined bottom wall, and a generally vertical end wall attached together to define in cross section a generally right triangle, said housing also having two generally vertical side walls having a said-generally-right-triangle shape, said side walls attached to said top, bottom, and end walls to define a fuel-tight, generally right-triangular wedge, said top wall having a fuel inlet orifice, said end wall having at least one convergent-divergent fuel outlet nozzle, and at least one wall of said bottom and side walls having a plurality of spaced-apart fuel-exit holes, wherein said bottom wall of each said fuel injector is generally coplanar and coextensive with said upper wall of said inlet.
