Zhuque-2
LandSpace Technology Corporation (doing business as LandSpace) is a Chinese private space launch provider based in Beijing. It was founded in 2015 by Zhang Changwu. LandSpace developed its first launch vehicle Zhuque-1, powered by solid-propellant motors. Zhuque-1 was launched on 27 October 2018, however the payload failed to reach orbit due to an issue with the third stage. The company also developed the liquid-fueled Zhuque-2, based on its methalox TQ-11 and TQ-12 engines, whose maiden launch (failed to orbit) occurred in December 2022. Launch vehicles Zhuque-1 Zhuque-1 (ZQ-1, Chinese：朱雀一号 or 朱雀·南太湖号), also called LandSpace-1 or LS-1 (the name LandSpace-1 or LS-1 was originally reserved for a different rocket that did not in the end materialize; after cancellation of the rocket, the name LandSpace-1 was then affiliated to LandSpace's rocket-to-be-developed at the time, the Zhuque-1), is a -tall, three-stage solid-propellant rocket.

TQ-12 is the first Chinese liquid rocket engine developed with private funding. The engine has been designed to produce of thrust at sea level. History The engine passed its first power pack test including the turbopump, valves, ignition components, and the gas generator at a LandSpace facility in Huzhou Huzhou (, ; Huzhounese: ''ghou² cieu¹'') is a prefecture-level city in northern Zhejiang province (Hangzhou–Jiaxing–Huzhou Plain, China). Lying south of the Lake Tai, it borders Jiaxing to the east, Hangzhou to the south, and the provinc ... on March 25, 2019. The engine's first full assembly was delivered in May 2019, and a hot fire test was successfully conducted the same month. The engine passed its first 200 seconds variable thrust test on October 26, 2019. Series of 400s hot fire tests were conducted in January 2021 ...

TQ-11
The TQ-11 (, lit. ''Sky Lark 11'') is a gas-generator cycle rocket engine burning liquid methane and liquid oxygen under development by Landspace. It will be used as the second stage vernier engine for Landspace's ZQ-2 rocket. The engine has been designed to produce of thrust in the vacuum. History Landspace completed the first engine hot firing test for TQ-11 on November 3, 2019, and the engine passed a 1500 second test in 2020. On December 14, 2022, Zhuque-2 LandSpace Technology Corporation (doing business as LandSpace) is a Chinese private space launch provider based in Beijing. It was founded in 2015 by Zhang Changwu. LandSpace developed its first launch vehicle Zhuque-1, powered by solid-propel ... completed its maiden flight. The TQ-11 engines used in the rocket's second stage failed, resulting in mission failure. LandSpace planned to upgrade the second stage with one TQ-15A engine, eliminating the need for a vernier engine. The failure of TQ-11 could force LandSpa ...

Liquid Rocket Propellant
The highest specific impulse chemical rockets use liquid propellants (liquid-propellant rockets). They can consist of a single chemical (a monopropellant) or a mix of two chemicals, called bipropellants. Bipropellants can further be divided into two categories; hypergolic propellants, which ignite when the fuel and oxidizer make contact, and non-hypergolic propellants which require an ignition source. About 170 different propellants made of liquid fuel have been tested, excluding minor changes to a specific propellant such as propellant additives, corrosion inhibitors, or stabilizers. In the U.S. alone at least 25 different propellant combinations have been flown. As of 2020, no completely new propellant has been used since the mid-1970s. Many factors go into choosing a propellant for a liquid-propellant rocket engine. The primary factors include ease of operation, cost, hazards/environment and performance.

Vernier Thruster
A vernier thruster is a rocket engine used on a spacecraft for fine adjustments to the attitude or velocity of a spacecraft. Depending on the design of a craft's maneuvering and stability systems, it may simply be a smaller thruster complementing the main propulsion system, or it may complement larger attitude control thrusters, or may be a part of the reaction control system. The name is derived from vernier calipers (named after Pierre Vernier) which have a primary scale for gross measurements, and a secondary scale for fine measurements. Vernier thrusters are used when a heavy spacecraft requires a wide range of different thrust levels for attitude or velocity control, as for maneuvering during docking with other spacecraft. On space vehicles with two sizes of attitude control thrusters, the main ACS (Attitude Control System) thrusters are used for larger movements, while the verniers are reserved for smaller adjustments. Due to their weight and the extra plumbing required ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zhejiang
Zhejiang ( or , ; , also romanized as Chekiang) is an eastern, coastal province of the People's Republic of China. Its capital and largest city is Hangzhou, and other notable cities include Ningbo and Wenzhou. Zhejiang is bordered by Jiangsu and Shanghai to the north, Anhui to the northwest, Jiangxi to the west and Fujian to the south. To the east is the East China Sea, beyond which lies the Ryukyu Islands. The population of Zhejiang stands at 64.6 million, the 8th highest among China. It has been called 'the backbone of China' due to being a major driving force in the Chinese economy and being the birthplace of several notable persons, including the Chinese Nationalist leader Chiang Kai-shek and entrepreneur Jack Ma. Zhejiang consists of 90 counties (incl. county-level cities and districts). The area of Zhejiang was controlled by the Kingdom of Yue during the Spring and Autumn period. The Qin Empire later annexed it in 222 BC. Under the late Ming dynasty and the Qing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other plane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
