Royal industrial communication operation or strategy? The Chinese Aeronautical manufacturer Comac (Commercial Aircraft Corporation of China), a state company, said he considers embarking on the supersonic adventure.
The manufacturer, who seeks to find a place with Boeing and Airbus, presented a study around C949, a supersonic plane that would fly in Mach 1.6 (1,960 km/h) by 2049. which connects Shanghai with Los Angeles in five hours.
This study was conducted by the Shanghai Aircraft Research and Design Institute.
The imagined device is much higher than the legendary concord, with a variable fuselage, an autonomy of 11,000 kilometers (against 7,200 kilometers), silent and less greedy motors, generating a less strong supersonic boom, and will embark between 28 and 48 passengers in the business class, less than the 100 seats of the concord.
If Cabac has become a credible player in the aeronautical sector, in particular with his C919 that competes with the Boeing 737 single-color and the Airbus A320 (which has no certification for Europe and the United States yet), the observers remain skeptical. The development of a supersonic plane takes time, a lot of money and unique technical experience.
Obviously, the company has the support of the Chinese state that intends to make Comac a serious competitor of Boeing and Airbus. However, the manufacturer continues to depend a lot on Western technologies for their devices.
Propaganda?
Therefore, it is necessary to order between a certain propaganda disseminated by the Chinese authorities and the viability of said project, for which Comac has no experience. The year 2049 was not randomly chosen, corresponds to the centenary of the creation of the People’s Republic of China.
In this field, only one project, only a project seems concrete, is that of American boom technologies with overture.
The company successfully succeeded last January the first supersonic flight of its XB-1 demonstrator plane in Mojave Air & Space Port in California. It rose to 35,290 feet of altitude and pushed the gases to reach Mach 1.122 (or 1,385.4 km/h), therefore, it crosses the sound wall for the first time.
And it is also the first time that such a plan has developed independently of an army or a state.
The XB-1 is a demonstrator that should serve as a technical basis for the plane called overture that Boom really wants to produce and market.
Based in Denver, Colorado, the young company has been developing this device since 2014 since 2014. It has raised funds of $ 100 million in 2019 and received 130 Pre -orders of American and Japanese companies. Today it has its own super assembly user.
The objective shown by the manufacturer It is embarking Around 70 people for transoceanic connections. With a speed of 1.7 machines (against 2.2 for the concorde), it will fly twice faster than current devices.
Therefore, the overture is aimed at trips such as New York-Roma in less than 5 hours (instead of 8), San Francisco-Séul in just over 8 hours (instead of more than 12 hours) or Zurich-Philadelphia in less than 5 hours (instead of 9 hours). 600 roads on the planet would be usable, says Boom, much more than the concord. Boom Supersononic aims to “start up before the end of this decade.”
