NASA Glenn Research Center engineers have concluded Phase 2 testing of an innovative, external compression inlet that could be used on manned and unmanned supersonic aircraft. Called the Parametric ...

“We were in a turn and climbing when one of the inlets showed signs of instability. Shortly thereafter—KER BLAM!—the aircraft slammed my head against the side of the cockpit and then momentarily ...

A compression spike and indications of a bypass duct splitter buried inside the inlet may build on earlier quiet supersonic propulsion concepts studied by Rolls-Royce, NASA and Gulfstream, among ...

A series of wind tunnel tests revealed the unusual engine inlet positioning for NASA’s supersonic X-plane meets the performance goals for the Lockheed Martin-designed aircraft, a NASA Glenn Research ...

Gulfstream has released new drawings of a supersonic business jet design in patent application forms, revealing features such as a telescoping nose, highly-sloped fuselage and variable-geometry wings.
