Dajiang DJI FPV launch: 4k 60fps

The appearance of Dajiang FPV is very different from that of traditional UAV. In order to meet the high-speed flight, the four blade planes tilt forward greatly. The fuselage adopts streamline design and adopts grey fuselage similar to mavic Royal series, with a takeoff weight of 795g. UAV provides n, s and M gears with different speeds. The speed of M gear is the fastest, and the maximum horizontal flight speed can reach 39m / S (27m / s in China). The speed limit of N gear is 15m / s, and that of s gear is 27m / s. The maximum altitude of the UAV is 6000 meters. The UAV has a medium speed endurance of about 20 minutes and a maximum endurance of 16.8km in a windless environment. It can defend against level 6 wind. The UAV is equipped with a sensing system in the front and bottom [...]

Australia is experimenting with the innovative technology of "hydrogen production by splitting water" in the desert to take water from the air and produce green energy

A new project in Australia's interior will test an innovative technology to convert water into hydrogen by capturing water in the air and cracking it with solar energy, so that hot, dry areas can also become energy exports. Tennant Creek is an Australian town with three bars and 3000 people. It is the territory of Crocodile Dundee and has a warm desert climate. Like most parts of northern Australia, there is plenty of sunshine, but not a ton of water to export. Therefore, with Australia positioning itself as a green hydrogen energy exporter, Tennant Creek has naturally become a good place to try new technologies. It is understood that this technology does not require a lot of municipal water, nor does it need to be connected to the local power grid to produce hydrogen. It is reported that Aqua aerem, a new start-up company, has signed a 12 week trial [...]

Why do we need NASA and space X at the same time

NASA's support for space X and other companies has reshaped the U.S. aerospace industry. Traditionally, deep-rooted aviation contractors with little or no competition now pay more attention to new technologies that can reduce Aerospace costs. American companies are now competing for the global launch market, which used to be the domain of Chinese and Russian rockets. NASA also benefits from having multiple domestic and international partners to launch spacecraft and deliver crew and cargo to the international space station. Space X has helped to revive public interest in space flight. The company's excellent use of live technology makes every rocket launch and landing an exciting thing. The interest in what space X does (usually with NASA) has inspired a new generation to pursue an exciting space career. But humans still need NASA, which does much more than send astronauts into orbit. There is no business case for launching a spacecraft [...]

How space X and NASA compete

There is no competition between them. Space X is a for-profit company, while NASA is a taxpayer funded entity that is free to pursue scientific discoveries that are not directly related to economic benefits. With space X, do we still need NASA The competition between space X and NASA is usually related to NASA's "Artemis Project". In 2004, President George W. Bush announced a plan to decommission the space shuttle and return humans to the surface of the moon. This led to the birth of a crew capsule called Orion, and eventually a rocket that evolved into a space launch system (SLS). Orion and SLS are made by aerospace companies Lockheed Martin and Boeing, which in turn use their own private suppliers and subcontractors. Under the guidance of NASA, these devices are assembled in the center of NASA, and the final products are owned by NASA. These projects created tens [...]

With SpaceX, do we still need NASA

In the past, launching satellites or other spacecraft into space was a collaboration between government agencies and large Aerospace contractors. But that's history, and over the past 20 years, private space startups have proved that they can compete with larger peers and, in some cases, even take the lead. The best proof is space X, Elon Musk's space exploration technology company. Now, space X has the ability to recycle the first stage rocket and reuse it for many times, which is the scene of science fiction. In 2020, space X will also become the first private company to send astronauts into space. Currently, space X is building a huge new rocket system, which is expected to send humans to Mars one day. Looking at these incredible feats, you may wonder whether we still need NASA, or whether NASA and space X are competing with each other. But in reality, the [...]
