Aiming for practical application of supersonic aircraft flying over Mach 5 until 2030 is shining the United States and China

In order for an aircraft to fly at a speed exceeding Mach (speed of sound), it is necessary to clear many conditions, and the aircraft that has exceeded Mach so far is limited to military aircraft of all countries except for the supersonic passenger plane "Concorde" It is a state that is being done. Although it is a supersonic aircraft whose development has been limited due to the adverse impact on the environment caused by the shock wave generated beyond Mach and high cost etc., it is said that the development is proceeding so that the United States and China are currently cutting their pace .

The Lockheed Martin of the United States is advancing the research, military hypersonic unmanned aircraft with the best speed Mach 6 "SR-72"is. Military-related development among Lockheed MartinSkunk works(Skunkworks) is studied by the department and is aiming for the first flight by 2030.


It was deployed in the actual war from the 1960's to the 1980'sSR-71SR-72 has the name followed by the "TRCC engine" (Turbine) equipped with a dual ramjet engine suitable for generating thrust in the hypersonic region in addition to a jet engine that normally accelerates to Mach 3 after takeoff By using the system called Rocket Combined Cycle, it enables a hypersonic flight of Mach 6 at an altitude from 30,000 meters to 100,000 meters.The TRCC engine is a flight with a normal jet fighter mounted To be realized by 2020, aiming to complete the aircraft by 2030 and put it in a state of actual deployment deployment.

Another aim at the American camp aims to realize another hypersonic aircraft,DARPASpace plane where Boeing, who was assisted by the National Defense Advanced Research Projects AgencyXS-1"is.


XS-1 is a space plane of a type combining an airplane with a wing and a rocket, and in the first stage performing liquid-fueled supersonic flight, payload (launch cargo) is set at a high altitude of 300,000 meters to 100,000 meters , To ignite the second stage rocket and carry the payload to a higher space. Up to 1.5 ton payload can be launched, the first stage is to return to the airport after flight and to be able to re-launch within 24 hours.

Meanwhile, a state-owned enterprise that is advancing space development in China ·CASIC(Chinese Aerospace Science and Industry Corporation: China Aerospace Engineering Group) are also developing similar aircraft. The spacecraft "Teng Yun" that the organization is developing is an aircraft that realizes a two-stage launch similar to XS-1, but the great difference is that the second stage rocket can be reused It is said that it will be possible to launch cargo or five astronauts up to 2 tons.


In the image at the time of launch, you can see how it is launched with a small second stage rocket on top of the larger first stage. Also, by using only the first stage, it is also possible to carry payloads of about 10 to 15 tons, and of course it is possible to use for military purposes as well.


Another state-owned company is also pursuing similar research in ChinaCASC(China Aerospace Science and Technology Corporation: China Aerospace Group Co., Ltd.). In August 2016, CASC completed the engine technology "TRRE (turbo-aided rocket-augmented ram / scramjet engine)" on hypersonic aircraft by 2020 and realized the flight with a real aircraft by 2030 We are announcing plans to make it.


CASIC of "Teng Yun" and Boeing of the XS-1 and similarly, that of a planned rocket launch of re-using the CASC. Pattern that is a plan to promote partially reusable rocket with a rocket engine, fully reusable rocket with a rocket engine, and the development of a fully reusable rocket that uses a TRRE engine in stages.


Through this development, CASC aims to establish a technology to carry people and cargo to outer space, and also watches space tourism flying with passengers on the second stage.
