Aerospace Industry Of China
As of December 2017, there are 229 commercial airports in China. Around 500 airports of all types and sizes were in operation in 2007, about 400 of which had paved runways and about 100 of which had runways of 3,047 m or shorter. There also were 35 heliports in 2007, an increasingly used type of facility. With the additional airports came a proliferation of airlines. China has the fastest growing passenger air market of any country in the world (by total passenger numbers) and between 2009 and 2014 the number of passengers increased over 47% from 266,293,020 to 390,878,784. In 2014 China was second only to the United States in total numbers of passengers carried. History The Nanyuan Airport first broke ground in Beijing near the end of the Qing Dynasty, and Chinese aviation pioneers Qin Guoyong and Li Ruyan, the principal and chief of the flight school operations established there in 1913 under then-president Yuan Shikai, had established the first airline service with a ro ...

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.

Aerospace Companies Of China
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Research ...

OneSpace
OneSpace ( zh , s=零壹空间 , p= Líng Yī Kōngjiān , l= Zero One Space ) or One Space Technology Group ( zh , s= 零壹空间科技 , p= Líng Yī Kōngjiān Kējì , l= Zero One Space Technology ) is a Chinese private space launch group based in Beijing, subsidiaries in Chongqing, Shenzhen and Xi'an. OneSpace was founded in 2015. OneSpace is led by CEO Shu Chang, and is targeting the small launcher market for microsatellites and nanosatellites. OneSpace launched China's first private rocket in 2018. The company plans to unveil its family of rockets early in 2019. At least 10 such firms have emerged since the Chinese government policy shift in late 2014 to allow private companies into the launch and small satellite sectors. Facilities OneSpace's headquarters and an R&D center is located in Beijing. Its research and development center, and manufacturing and assembly base, is located in Chongqing. Its rocket engine testing facility is located in Jiangxi Province and Shanxi Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I-Space (Chinese Company)
i-Space ( zh, s=星际荣耀, p=xīngjì róngyào, l=Interstellar Glory)—also known as Space Honor, Beijing Interstellar Glory Space Technology Ltd., Interstellar Glory or StarCraft Glory—is a Chinese private space technology development and space launch company based in Beijing, founded in October 2016. The company is developing two-stage small satellite orbital launchers based on solid propellant rocket engines procured from major Chinese government supplier China Aerospace Science and Technology Corporation (CAST). In July 2019, i-Space successfully launched the Hyperbola-1 and reached low Earth orbit on its maiden flight, becoming the first private company from China to achieve orbit. A second launch of the Hyperbola-1 in February 2021 failed to reach orbit, as did the third attempt in August 2021 and the fourth in May 2022. History The company was founded in 2016.

Rocket Engine Test Facility
A rocket engine test facility is a location where rocket engines may be tested on the ground, under controlled conditions. A ground test program is generally required before the engine is certified for flight. Ground testing is very inexpensive in comparison to the cost of risking an entire mission or the lives of a flight crew. The test conditions available are usually described as ''sea level ambient'' or ''altitude''. Sea level testing is useful for evaluations of start characteristics for rockets launched from the ground. However, sea level testing does not provide a true simulation of the majority of the operating environment of the rocket. Better simulations are provided by altitude test facilities. Sea level tests The facility must restrain the rocket and direct the rocket exhaust safely toward the open atmosphere. Structural integrity, system operations, and sea level thrust can be measured and verified. However, rockets are primarily intended for operations in very thi ...

Thrust
Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system. The force applied on a surface in a direction perpendicular or normal to the surface is also called thrust. Force, and thus thrust, is measured using the International System of Units (SI) in newtons (symbol: N), and represents the amount needed to accelerate 1 kilogram of mass at the rate of 1 meter per second per second. In mechanical engineering, force orthogonal to the main load (such as in parallel helical gears) is referred to as static thrust. Examples A fixed-wing aircraft propulsion system generates forward thrust when air is pushed in the direction opposite to flight. This can be done by different means such as the spinning blades of a propeller, the propelling jet of a jet engine, or by ejecting hot gases from a rocket ...

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
