China inAstronauticsA major breakthrough has been made in the field, and a reusable test has been successfully issuedAstronauticsUtensil. ThisAstronauticsIt is independently developed by China and is known as an aerospace vehicle that is "too advanced and inconvenient to display". It has already flown two missions before, using China's own CZ-2FRocketsCarry out the launch. The first mission was completed in 2020 and lasted more than 1 day;The second mission was launched in 2022 and lasted 276 days. Now this is its third flight, and it is believed that it will be in orbit for a longer time.
This trialAstronauticswith the United Statesx-37bThere are some similarities in that they all need to rely on carryingRocketsCarry out the launch. But it is important to note that this cannot be called "in the true sense of the word".Aerospace aircraft”。Although they are shaped to look like airplanes and are capable of flying into space, they are inAtmosphereOnly unpowered gliding flights can be carried out. In general, they belong to the small ones".Astronauticsairplanes".
Successful launch test in ChinaAstronauticsAt the same time, the United StatesRocketsBut there were some difficulties. For example, the United StatesULA rocketThere was a delay in the launch of the Peregrine Probe to the Moon. And SpaceX's Falcon 9 is heavyRocketsCarryx-37bThe tasks of the aircraft were also postponed because they needed to be reconfigured. In contrast, the Chinese oneLong March-2F rocketHowever, it has always maintained a high success rate and is known as the "magic arrow".
There are several reasons for this discrepancy. First of all, ChinaAstronauticsThe cause has always adhered to the pursuit of highReliabilityand the spirit of high security, always keep improving. Whether it is the chief designer or other related personnel, it is always an important task to inherit technology and accumulate technology.
Secondly, ChinaAstronauticsGrowing up in an environment of siege and lockdown, they are constantly pushing their limits. Long March carryingRocketsThe increase in the number of launches per year is also a reflection of their continuous breakthroughs. And the United States, after the end of the Cold War, carried out "deindustrialization" and "hollowing out of manufacturing", making theirRocketsThere is a fault line in the inheritance of technology, which is easy to cause the problem of delay and technology advancement.
Finally, the United States is inAstronauticsThe contractor approach employed by the field, which leads to their carryingRocketsThere are many problems with the ** business. ** The situation of the quotient is unstable, resulting inRocketsThe inheritance and development of technology is facing difficulties. China, on the other hand, has adopted an independent research and development approach, which allows it to control betterRocketstechnology and progress.
According to China's development plan, China is inAstronauticsThe field has a clear technical route and development goals. According to the "863 Project" and "921 Project", ChinaShenzhou spacecraftThe construction of the space station has been successfully implemented, on the basis of which research and verification of a new generation of spacecraft have been carried out.
China's current research and development direction includes small-scale "Astronauticsairplanes" and large" suborbital reusable launch vehicles. Small".Astronauticsairplanes "are similar to Americanx-37b, need to rely onRocketsCarry out a vertical take-off booster launch, and then in theAtmospherePerform unpowered gliding flights. The large "suborbital reusable launch vehicle" has horizontal take-off and landing capabilitiesAerospace aircraft, similar to the Soviet "Buran" and the American oneColombiaNo.".AstronauticsAirplanes, which can be plugged in or built-inRocketsNudge.
ChinaAstronauticsThe success of development is inseparable from the inheritance and accumulation of technology, as well as for highReliabilityand the relentless pursuit of high security. ChineseLong March-2F rocketThe success rate has always been high, which is also due to the fact that China has always maintained a Xi attitude and has constantly pushed its own limits in technology.
In short, ChineseAstronauticsThe cause continues to grow and develop, and important achievements have been made. At the same time, we should also remain humble from othersAstronauticsXi and learn from experience in a strong country to avoid making similar mistakes for our countryAstronauticsProvide strong support for the further development of the business.
