[Global Network Reporter Xu Luming] At the Tianjin Direct Expo in 2019, a mysterious flying saucer-like aircraft in the outdoor static exhibition area was placed in the most prominent position. Although the information on public display shows that it is a wing-body fusion high-speed helicopter called Super Great White Shark, it is still difficult for ordinary audiences to connect it with the helicopter. To this end, Global Network reporters interviewed the development side of this UFO to uncover the mystery of this aircraft.
Key words: military use
According to the field personnel of the Big-billed Parrot Aerospace Technology Laboratory who developed the helicopter, Super Great White Shark is a Wing-Fuselage high-speed helicopter designed for military purposes. Its original intention is to consider military purposes. As a military aircraft, the current open static model and structural diagram do not show the weapon mounting mode of this high-speed helicopter. Reporters learned from the scene that the aircraft will mount weapons by installing short wings and weapon racks on both sides of the fuselage, which is the same way as the current mainstream armed helicopter short wings mounting weapons. However, considering the aerodynamic sound speed, the shape design of the short wings and hangers of the Super Great White Shark will be specially processed and optimized.

At present, in the world, wing-body fusion helicopter technology can be said to be a blank in the field of military applications. As soon as Super White Shark appeared, it was reported by American, British and Russian media. Foreign media also pay close attention to the official presentation of the helicopter, such as a composite Wing-Fuselage fusion high-speed helicopter configuration designed for future digital information battlefield.
According to an article published in the Daily Star on November 11, Super Great White Shark has attracted wide attention because of its unique shape design. It looks like it was inspired by alien science fiction movies. The report quoted an unnamed former MI6 chief as saying that if it could successfully fly into the sky, it would be the first fused wing-body aircraft ever to work properly. Russia Today also said that if Super Great White Shark could operate in the sky, it would mean that Chinese helicopter designers have solved a centurys problem of building a fused wing-body aircraft that can work properly, which has been one of the problems that have plagued the Western helicopter industry since World War II. The Drive, a US military website, reports that the super white shark may evolve into an advanced, high-speed, ground-to-ground wing vehicle capable of fast maneuvering missions at altitudes close to the ground, which is valuable for reconnaissance or temporary raids.

Key words: wing-body fusion
UFO-like wing-body fusion aircraft was once a top-secret weapon developed by military powers, but it faced technical obstacles in the early stage, which could not meet the needs of actual use and combat. During the Cold War in the 1950s, the United States developed a prototype aircraft called the Avro Flying Vehicle. At that time, the Avro Flying Vehicle was a sci-fi explosion meter, with 124 blades in the central circular hole 1.5 meters in diameter. It was driven by three J69 turbojet engines. There were two bubble independent cockpits in the upper layer and three wheel landing gears underneath.
The US Army Secretly Developed Avro Flying Vehicle
However, the performance of the Avro Flying Vehicle in the subsequent tests was unsatisfactory. First of all, the stability problem caused by the complex power transmission structure was exposed, and the mooring test in September 1959 also occurred the phenomenon of uncontrolled oscillation. The flight performance of the prototype in the actual test can not satisfy the U.S. military. The maximum speed is only 56 km/h, and the flight altitude is only 1.1 m, which is completely unable to compare with the ordinary fighter. Due to technical problems, the Avro Flying Vehicle project did not achieve satisfactory results until the end of 1961. With the passage of time, the Avro Flying Car program has come to an end.
The main reason for the failure of the Avro Flying Vehicle is its stability. Super Great White Shark and Avro Flying Vehicle adopt completely different design concepts. Super Great White Shark belongs to a culvert aircraft, but strictly speaking, it is a high-speed helicopter with a composite wing-body configuration. At the same time, it adopts a coaxial twin-rotor design, which provides lift while counteracting the counter-torsion. At the same time, the rotor system also has a high-speed helicopter. After optimization, the stability of the aircraft can be maintained in high-speed flight.
Overall Layout of Super Great White Shark
The rotor of traditional coaxial twin-rotor helicopter is located at the top of the helicopter and can maintain good stability at low speed. However, in the complex environment of high-speed flight, intense turbulence can easily make the helicopter out of control. Wing-body fusion can solve this problem well. The design of super-great white shark has the final configuration only with the accumulation of previous generations of technology. u3002
Many netizens questioned this, believing that super great white shark seems to have little in common with these helicopters in appearance. Where did the so-called reference design come from? To this point, the scene personnel also carried on the answer. According to him, before the development of Super Great White Shark, the laboratory had fully studied five configurations of conventional single-rotor with tail rotor, coaxial twin-rotor, longitudinal twin-rotor, parallel twin-rotor and cross-twin-rotor, and accumulated abundant technology. On the basis of thorough research on these basic configurations, the Super Great White Shark configuration was formed, and the wing-body was integrated in it. The application of helicopter technology is also based on the traditional helicopter configuration. The design concept of Super Great White Shark also opens up a new way of thinking and direction in the application of wing-body fusion technology in helicopter field.

In the development plan of Super Great White Shark, the future high-speed helicopter project named XS-1 was also launched, aiming at developing a new type of high-speed helicopter with manned configuration based on artificial intelligence era and an auxiliary wingman (a high-speed unmanned helicopter) to verify the application of wing-body fusion technology in helicopter design field.

According to reports, the high-speed helicopter will realize the free transition from low speed to high speed through the rudder or turbojet engine on both sides after takeoff, with the maximum design speed of 650 km/h and cruise speed of 450-600 km/h. The high-speed helicopter will eventually achieve a maximum takeoff weight of 13,227 pounds (about 6 tons), which can carry a minimum payload of 3306 pounds (about 1.5 tons) and a maximum payload of 5511 pounds (about 6 tons). 2.5 tons) to meet the rapid maneuvering deployment of combat units in the future military field; at the same time, this Wing-Fuselage fusion configuration of high-speed helicopter will achieve the maximum load of 1575 km (450 km/h flight 3.5 hours), or airplane transit flight 2950 km (650 km/h flight 4.5 hours); and verify its pilot ejection lifesaving system, which will accumulate preliminary information for future high-speed helicopter flight safety. Technical experience.
Key words: future straightening
In addition to the static model of Super Great White Shark, another straightening technology program was also displayed at this direct exposition. According to the design data, this heavy transport helicopter named Elephant King has a rotor diameter of 37.6 meters, a height of 10.6 meters, an air weight of 29 tons, a maximum take-off weight of 58.5 tons, a maximum horizontal flight speed of 450 km/h, a range of 2350 km, a practical lift limit of 7000 meters, and its crew consists of five people.

From the design data, this new configuration of wing-body fusion straightening technology is better than the existing Russian Mi-26 helicopter overall performance, but because there is no technical validation aircraft flight test, the design data can only be used as a reference. According to their laboratory engineers, there is still a long way to go in the field of high-speed Helicopter Research and development in China.
