It must be said that Google's drones have been in full swing recently, not only returning to the center of global technology media focus, but also receiving clear support from the White House. Burning!
However, Xiaobian's Virgo colleagues have noticed that there are some voices overseas that call ProjectWing a work of art. They can't be touched, and there are too many difficulties. The distance is still far away, so Google is likely to skip the ticket this time.
Strong Google will jump tickets? How can this be?
Calm down and think about it, this kind of questioning is not impossible. Although in this project, Google has concentrated almost all the world's ideas. Among them are researches on small-scale battery-driven vertical landing technology from China, Kalwa's research on drones in uncertain environments in ProjectGREX, and even the research results of Kawashima's anti-disaster system NEDO. However, it is a huge challenge for Google to successfully develop a tailstock-type unmanned aerial vehicle that can be freely converted between two flight modes and can fly vertically and horizontally.
Today, Xiaobian will bring you to understand the past and present life of the tailstock drone, and the spoiler of a Chinese advanced tailstock drone, I hope that after the spoiler, Xiaobian does not have to be invited to drink coffee.
First, the difficult exploration
The tailstock aircraft first began in World War II Nazi Germany. In the spring of 1944, the Allies began a deep bombing of the German mainland, which made it difficult to find even a complete take-off runway even though the German Nazis had a large interceptor group. As a result, the German Nazis began to consider the development of an aircraft that does not rely on the airport, can use small open space for take-off and landing. In the end, the German Nazis accepted Bachem's Ba349 vertical take-off interceptor program, and wanted to create a new concept fighter that could take off from any place and then use rockets to attack the Allied bombers, scattered in hidden locations, in the alliance. The army bomber group was attacked when it passed. This new concept fighter with a rocket bombing the Allied bomber is also the origin of the tail-mounted aircraft. But the war soon ended in the following year, and the tailstock aircraft became the doomsday technology of the German Nazi leader.

After World War II, the United States and Europe were also very interested in tailstock aircraft. In 1948, when the US Navy tendered for fighters that could take off and land vertically from the deck of a warship (not an aircraft carrier), a total of eight design proposals were proposed by six companies. Two years later, the US Navy chose Convair XFV-1 and Lockheed XFY-1 to enter the finals. However, during the flight test, the XFV-1 prototype crashed during the landing. The XFY-1 prototype was eventually put on hold due to difficulties in handling and insufficient engine power. In the same period, the US Air Force and Ryanair also developed the X-13 verification machine. In 1957, the X-13 successfully conducted a test flight, which verified the technology of the jet tail-type aircraft, but it was not further developed due to poor practical performance. During this period, the most valuable mention was the “Beetle†series. The European tail-seat aircraft was mainly led by Dr. Zborovsky, a German engineer who had worked as a German engineer during World War II, and designed the "chafer", "蜣螂", "象虫" and "bean elephant". The series is named after the beetle. In 1959, the "Beetle" carried out 8 test flights, and the 9th test flight lost control of the explosion, after which the project was terminated.
The outdoor patch cable is four pairs of UTP/FTP/SSTP CMR cable, suitable for outdoor aerial and pipe, can prevent moisture intrusion.
The performance meets the requirements for the patch cables in ANSI/TIA/EIA-568B.In order to make the twisted pair in the movement of the wire will not break, except for the skin protective layer, the external PE also has a certain toughness.
At the same time, in order to facilitate the joint production and reliable connection, copper core should not be too soft, not too hard, too soft is not easy to joint production, too hard is easy to produce joint fracture;With the technological innovation, double-layer sheath can solve more technical problems of weak current system more effectively.
