HELSINKI Chinese private firm LInkSpace has performed its most ambitious Launch and Landing test so far amid a flurry of activity in the Commercial Launch Vehicle sector. LInkSpace Aerospace Technology Group, private Launch company established in 2014, carried out its third low-altitude untethered Launch and Landing test of its RLV-T5 tech demonstrator at 10: 30 pm Eastern August 9, in the latest step in developing a reusable orbital Launch Vehicle. 8. 1-meter-tall, 0. 65-meter-diameter, 1. 5-metric-ton rocket reach altitude of 300. 2 meters during its 50-second flight before making powered descent and Vertical Landing with an accuracy of 0. 07 meters, LInkSpace CEO Hu Zhenyu state on Sina Weibo, Chinese Twitter-like service. Launch follows two tests reaching 20 and 40 meters in March and April respectively. The latest test was carried out at a new facility in Lenghu region of Qinghai province in the northwest of the country. Chinese magazine Future Aerospace states that RLV-T5 is powered by five variable-thrust rocket engines which use ethanol and liquid oxygen, propellant combination used by German V2 rockets. The company will move ahead to kilometer-level test before proceeding to the larger RLV-T6 tech demonstrator Rocket. A full test flight of the newline-1 orbital launcher, to be capable of carrying 200 kilograms to 500 kilometers Sun-Synchronous orbit, is planned for 2021. The RLV-T6 Reusable tech demonstrator will be designed to reach altitudes of around 100 kilometers. According to Chinese press reports, RLV-T6 will be powered by Lingyun 10-ton thrust methalox engines developed by Jiuzhou Yunjian. Jiuzhou Yunjian is a BEIJING-base Aerospace startup founded in 2017 which last month carried out tests of the Lingyun engine which the company says demonstrated deep throttling and restart capabilities. In June, the firm tested the gas generator for the larger 80-ton thrust Longyun methalox engine. LInkSpace is one of four entities considered to be the first wave of Chinese private launch firms. Whereas Landspace, OneSpace and iSpace have chosen first to pursue and launch solid propellant launchers, LInkSpace has concentrated solely on developing reusable, liquid propellant launcher. Chinese NewSpace companies have received government support including Technology transfer since the policy shift in 2014, but they will also face competition from traditional space and defense contractors. Chinarocket Co., Ltd., Subsidiary of China Aerospace Science and Technology Corporation, main contractor for China Space programs, is set to test launch its Commercial Jielong-1 solid microlauncher in August following transportation to Jiuquan Satellite Launch Center in late July. Jielong-1 is designed to be fast, agile and flexible and capable of putting 150 kilograms into the 700-kilometer SSO. Test Launch will include payloads with involvement from NewSpace Satellite manufacturers BEIJING Qiansheng Exploration Technology Co., Ltd., And BEIJING Weina Star Technology Co., Ltd., Also know as Minospace, both founded in 2017. Further competition will come from the Long March 11 Launch Vehicle.

Rockets

Photo LinkSpace Reusable Rocket Landing Test do on August 10 2019. The private Chinese space industry is literally taking off and landing. August 2019, LinkSpace, Chinese New Space startup Test its prototype Reusable Rocket RLV-T5. This was the third successful LinkSpace Test this year of vertical-takeoff / vertical-Landing Technology, each progressively higher. LinkSpace completed its third successful Test of Reusable Rocket, taking it to new heights. The LinkSpace program has progressively been testing and exceeding prior accomplishments. First, in March 2019, LinkSpace reach about 20 meters. Then, in April 2019 tests, RLV-T5 blew that record away and reached 40 meters altitude. LinkSpace Launch this weekend blew those prior records away, reaching 300 meters. Through these accomplishments, LinkSpace is capturing the hearts and imaginations of Chinese people, similar to what SpaceX and Blue Origin did for America a few years ago. While most Americans were sleeping, halfway across the world in China, RLV-T5 Rocket blasted off in the desert in western China away from population centers. Even though the test was essentially in the middle of nowhere, LinkSpace Test Launch still drew crowd. LinkSpace is quickly becoming an iconic space company for Chinese to rally around. Spectators travel far from east of China to be onlookers to spectacle as RLV-T5 lifts off and reaches an altitude of about 3 / 10 of kilometer. For those that were not present, they were waiting to receive updates via WeChat, popular form of instant messaging. Many WeChat messages of congratulations were sent after RLV-T5 touch back down with just under 1 minute of flight time. LinkSpace will continue to draw local support in China and attention globally. LinkSpace will continue to draw local support like that of Mars Society China, who see reusable rockets as a necessary for their dream of reaching Mars. Ms. Angela TingTing Cui of Mars Society China Chapter was excited to see Launch. Originations like Mars Society are helping fuel new find pride in the Chinese Space industry. They are not only supportive of current efforts and helping bring public attention to accomplishments, but they are planting seeds of interest in next generation of engineers, astronauts and potentially even mar explorers. Mars Society China helps coordinate education outreach programs and summer camps for youth to become engaged in STEAM activities. Ms. Cui believes that excitement is just getting start. She, along with 260 000 others, have registered to go to Mars via Mars insight rover, courtesy of NASA. Ms. Cui further explains that this was a historic day, as everybody was excited about the first online broadcast for Chinese Rocket. Ms. Cui believes that Mars excitement in China will continue to grow. I believe 2020 Mars trend will more hotter Earlier this year, Mars Society President Dr. Robert Zubrin and his wife made visit to China. During the visit, Zubrins and Ms.

Inspiration or duplication

When new Line 1 was announce, media immediately drew comparisons between LinkSpace's reusable Rocket Booster and only currently flying, Orbital-class reusable Rocket Booster, SpaceX Falcon 9. LinkSpace's design features grid-fins, flat lattice control surfaces, as well as four extendable Landing legs that borrow a triangular shape and central piston from SpaceX's design. While design similarities are obvious, it is important to understand engineering considerations that may have led to these design choices. Grid fins are an interesting technology that has been used in aerospace for decades. The design allows for excellent control authority in relatively small space across supersonic and subsonic regimes. Grid fins have been a feature on Soyuz Launch abort System for decades, aiding in post-abort stability. They have also been used on bombs and missiles for compact, aerodynamic control at high speeds. New Line 1's Landing leg design is less readily defend. Using four landing legs instead of three provides tangible benefit to stability. However, low mass Landing leg designs take variety of forms, from retractable spindly legs of New Shepard, to stubby legs of Delta Clipper. Potentially, different design might be lighter or more effective for their smaller vehicle. The wide-swept legs of Falcon 9 provide a wide base to stabilize the 40m tall first stage. The new Line 1 will be half as tall with its second stage still attach. It will BE interesting to see if the new Line 1's leg design changes as the company gets closer to building first vehicle. Use of kerosene and liquid oxygen as propellants also makes sense from a reusability perspective. The density of kerolox reduces the overall size of the rocket, meaning less tankage mass is needed, resulting in a smaller stage to returning to land. While kerolox propellant still causes coking within engine, making reuse harder, SpaceX has proven that it is not a significant issue, having flown many Merlin engines multiple times across multiple firings. While the unveiled design bears striking resemblance to other operational Launch vehicles, many of common design elements come from engineering considerations.

Future of reusable designs

A wide range and vast number of newspace companies have emerged in China following the 2014 policy decision to open Launch and Small satellite sectors to private capital. Approved firms have also received support through the civil-military integration national strategy, which facilitates transfer of restricted technologies in order to promote innovation in dual-use technology and reduce costs. LinkSpace belongs to the first wave of more established companies which have carried out orbital and suborbital launch attempts, along with OneSpace, iSpace and Landspace. Space Transportation, meanwhile, is part of the later second wave of commercial launch firms. Two of these, Galactic Energy and Jiuzhou Yunjian, also recently declared progress on Launch Vehicle projects. Galactic Energy, established in 2018, announced on April 12 that it received nearly 100 m RMB in series + financing in January from Kexin Capital, New Potential Energy Fund and others. Funding will be used for production of solid engines and related development of the Ceres-1 rocket, planned to be capable of placing 350 kilograms into 200-kilometer low Earth orbit and 230 kilograms to 200-kilometer SSO, and development of reusable liquid oxygen and kerosene engines for the future Pallas-1 Launch Vehicle. Jiuzhou Yunjian Space Technology Co., Ltd., Founded in 2017 and headquarters in Beijing, in March performed successful combustion chamber test as part of development of a methalox engine named Lingyun. The Variable thrust Lingyun engine will be capable of throttling to around 30 percent thrust, according to the company, allowing vertical recovery and reuse of Launch vehicles.
