The SR-72 project the fastest air using aircraft in the world

Lockheed-Martin Corporation has created the new concept for ultrafast aircraft what will succeed the SR-71 "Blackbird". The SR-71 was the fastest aircraft and it bases the technology, what was created in 1960's. The body of the aircraft was made of the titanium, and it has capable of flight Mach 3,2 to Mach 3,5. The maximum speed depends on the calibration and wealth of the jet engines, what were under very high pressure and temperature. And those extremely powerful jet engines were corrosion very fast, and if the motor was not thin, the maximum speed was decreased the little bit. But when the SR-71 program was canceled in 1998 there were not succeeded of that marvelous plane. And the rumors started to grow.


There was mentioned some airplanes what had code-named "Aurora" and there is actually no knowledge what does that world mean. In some discussions that were mentioned to mean the ramjet or scramjet motors or some other exotic propulsion systems like PDWS (Pulse Detonation Wave Systems". The PDWS is actually same kind of flap engine, what is used in German V-1 (Fi-103) flying bomb, In that engine has flap system, what allows the pressure of the fuel rise high, and then the ignition lightning will be given to the fuel and oxygen combination.


When the flaps what are in the front of the engine are open, the motor will suck the air, and then the frontal flaps will be closed, and the flaps of the exhaust tubes will be opened, and same time the ignition spark will be given to the motor, and then the exhaust gas would be given the speed of the vehicle. This system allowed the launch of the V-1 bombs from the ramps without the rocket. The frontal flaps were closed, and then the fuel was injected into the combustion chamber, and then the fuel was sparked. The flap ramjet works in the same way, and only the shape of the motor is changed as the ramjet or scramjet motor.

When the speed of the airplane will rise high enough, both flaps can be stayed open, and then them motor works like normal ramjet motor. The flap systems allow to use ramjets in the low speed, and another way is, of course, use normal jet motors to accelerate the speed of the airplane and start the normal ramjets after the speed was increased high enough, that the ramjets can begin to operate, and normally that speed is about 900 kilometres per hour. The SR-72 is not like normal recon plane.


It would have the capacity for Mach-6, and it can fly any point of the earth in one hour. The Business Insider magazine will give the information, that SR-72 has not mentioned using only in the reconnaissance missions. That plane could use the smart bombs like Precision guide Nuclear Weapons, GBU-32 or Maverick and Hellfire missiles in its missions. Also, it can deliver MAV:s to the operational area. The plane would be unmanned and it might use the same kind of computer systems than "Predator-UCAV's" uses, and there might have the same kind of missions than those official UCAV's have.


But the SR-72 has more capacity to make the strikes than slower "Predators". In some scenarios, those "Super Predators" can be used against all targets what the conventional airplanes can be used. There might be many sizes of those very fast aircraft, and they can be carry also MAV:s (Miniature Aerial Vehicles) in the operational zone. So they can use also as the assassination missions what have targeted well-known terrorists and other criminals. Those super fast SR-72 aircraft can conduct the USAF global strike capacity, what will now get the change to take the control of the hostage situations.
