Boeing announces the idea of ​​a supersonic reconnaissance aircraft "Son of Blackbird" that jumps at 5 times speed of sound, 6000 km / h

Supersonic high-altitude strategy reconnaissance aircraft operated in the US Air ForceSR-71 BlackbirdAs a successor to the supersonic aircraft that Boeing can fly on Mach 5Son of BlackbirdWe announced the concept and the concept model of the concept.

In this concept model,American Aerospace AssociationForum to be held "SciTechWhat was announced in ". The idea was planned on the premise that it flew at Mach 6 at the maximum speed of Mach 5 which was higher than SR-71 which was the Mach 3, at about 6000 km per hour, and it was suitable for supersonic flight as a power source as well as a jet engineScramjet engineIs supposed to be adopted.

The bottom of the aircraft has a flat shape, somewhat irregularDelta wingShape with. And in the air intake which protruded to the bottom greatly it is structured to fit two scramjet engines.

When you see the aircraft from the top, you have a sharply pointed nose and you can see that the surface is composed of smooth curves. This is to reduce resistance during supersonic flight, at the same time to minimize heating of the aircraft by adiabatic compression, and to enhance 'stealth' which is hard to be captured by the radar. Also, the flat bottom surface is shaped to obtain lift by shock waves generated by supersonic flight, and this type of aircraft means to ride on the wave of shock wave "Wave riderIt is also called.


In Boeing, a testing machine that achieved Mach 9.68 (11,244 km / h) in 2004X-43And subsequentX-51AWe are setting up the concept of this aircraft based on, among others. Especially, it is a very difficult task to develop an aircraft that accelerates in the supersonic range from Mach 5 which is the speed range of ordinary jet aircraft, and from there to Mach 5, Boeing said that this In order to confront the challenges, we developed X-51A by adopting MDD (Multidisciplinary Design Optimization), which is a process that designers incorporate all related fields at the same time. And that know how is reflected in this time "Son of Blackbird".

This initiative is based on Lockheed Martin's Advanced Development Planning Department, which developed and produced the SR-71 Black Bird "Skunk WorksIs under developmentSR-72We are competing with each other, and both are undertaken with the help of the National Defense Advanced Research Projects Agency (DARPA). If a bowing plan is chosen, first make a demonstration machine of size F-16 fighter size equipped with one engine first, then develop research and development, then manufacture aircraft close to the actual aircraft and further research and development It is assumed that a two-step process is carried out. The final size of "Son of Blackbird" is scheduled to be about the same as 107 feet (about 37 meters) of the SR-71 Blackbird.

Although it is a high altitude supersonic reconnaissance aircraft that seems to play a major role in defense, on the other hand, the significance of its existence has been reexamined by evolution such as intelligence activities using reconnaissance satellites and drone machines that have greatly improved performance compared to the past There is also a movement to be. Also, in the case of Son of Blackbird or SR-72, which has a special structure, the body manufacturing cost and operation cost are greatly expanded, so discussion is also being made as to whether or not the result matching the budget can be obtained.
