just want to clarify a couple of points.
NO turbojet in the world will propell anything to mach 3! so the spud who said that, needs to go back to class. when it reaches Mach 1, the cones at
the intake move forward down the intake duct to restrict the airflow in the engine and to lower the ambiant pressure as it enters the combestion
section. from this point it then becomes a Ramjet, capable of taking the aircraft to around 3,500 KM/H around Mach 3.3-3.5 depending on the temp of
the air around the jet.
as for the raptor, go to
Lockheed Martin company website
The Aurora has been spotted over the North Sea by oil rig workers, doing air to air refueling. and the tell tale contrails from a pulse detonation
engine have been seen also from what im led to believe, the black projects are not tested at Nellis anymore, since its become too world famous. that
have apparently set up camp in som fairly inhospitable mountainous area in Montana or something.
The Foxbat does near enough mach 3, and is the aircraft to hold the record for the fastest and highest Ejection, Mach 2.6 at 66,000 ft! Nice!
fastest Passenger Jet in the world, since the demise of concord is another 1960's design, the Vickers VC10, currently in RAF service as a
passenger/cargo transport and Air to Air Refueling tankers. The Queen of the skies! wish i still worked on them, instead of the crappy Tornado!
