Kuwait Space Rocket
The Kuwait Space Rocket (KSR), is a Kuwaiti project to build and launch the first suborbital liquid bi-propellant rocket in Arabia. The project is intended to be the first step towards starting a space industry in the country and a launch service provider in the GCC region. The project is divided into two phases with two separate vehicles. An initial testing phase with KSR-1 as a test vehicle capable of reaching an altitude of and a more expansive suborbital test phase with the KSR-2 planned to fly to an altitude of . in May 16 Ambition-1 launched but had a malfunction with the parachute and crashed in free fall. History The project began in January 2018 for conceptual design and planning. The team started the fabrication of KSR-1 in early 2019, and as of January 2020, KSR-1 was fully built. KSR-1 KSR-1 is a vertically-launched single stage rocket. It uses a liquid bi-propellant rocket engine burning methanol as fuel and nitrous oxide as the oxidizer. KSR-1 is intended ...

Kuwait
Kuwait (; ar, الكويت ', or ), officially the State of Kuwait ( ar, دولة الكويت '), is a country in Western Asia. It is situated in the northern edge of Eastern Arabia at the tip of the Persian Gulf, bordering Iraq to the north and Saudi Arabia to the south. Kuwait also shares maritime borders with Iran. Kuwait has a coastal length of approximately . Most of the country's population reside in the urban agglomeration of the capital city Kuwait City. , Kuwait has a population of 4.45 million people of which 1.45 million are Kuwaiti citizens while the remaining 3.00 million are foreign nationals from over 100 countries. Historically, most of present-day Kuwait was part of ancient Mesopotamia. Pre-oil Kuwait was a strategic trade port between Mesopotamia, Persia and India. Oil reserves were discovered in commercial quantities in 1938. In 1946, crude oil was exported for the first time. From 1946 to 1982, the country underwent large-scale modernization, largely b ...

Oxidizer
An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or " accepts"/"receives" an electron from a (called the , , or ). In other words, an oxidizer is any substance that oxidizes another substance. The oxidation state, which describes the degree of loss of electrons, of the oxidizer decreases while that of the reductant increases; this is expressed by saying that oxidizers "undergo reduction" and "are reduced" while reducers "undergo oxidation" and "are oxidized". Common oxidizing agents are oxygen, hydrogen peroxide and the halogens. In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction. In the second sense, an oxidizing agent is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate. Combust ...

Suborbital Spaceflight
A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the atmosphere or surface of the gravitating body from which it was launched, so that it will not complete one orbital revolution (it does not become an artificial satellite) or reach escape velocity. For example, the path of an object launched from Earth that reaches the Kármán line (at ) above sea level), and then falls back to Earth, is considered a sub-orbital spaceflight. Some sub-orbital flights have been undertaken to test spacecraft and launch vehicles later intended for orbital spaceflight. Other vehicles are specifically designed only for sub-orbital flight; examples include crewed vehicles, such as the X-15 and SpaceShipOne, and uncrewed ones, such as ICBMs and sounding rockets. Flights which attain sufficient velocity to go into low Earth orbit, and then de-orbit before completing their first full orbit, are not considered sub-orbital. Example ...

Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pad, launch pads, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as Solid-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Injector
An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow. A steam injector is a typical application of the principle used to deliver cold water to a boiler against its own pressure, using its own live or exhaust steam, replacing any mechanical pump. When first developed, its operation was intriguing because it seemed paradoxical, almost like perpetual motion, but it was later explained using thermodynamics. Other types of injector may use other pressurised motive fluids such as air. Depending on the application, an injector can also take the form of an ''eductor-jet pump'', a ''water eductor'' or an ''aspirator''. An '' ejector'' operates on similar principles to create a vacuum feed connection for braking systems etc. History The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressure-fed Engine
The pressure-fed engine is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To maintain adequate flow, the tank pressures must exceed the combustion chamber pressure. Pressure fed engines have simple plumbing and have no need for complex and occasionally unreliable turbopumps. A typical startup procedure begins with opening a valve, often a one-shot pyrotechnic device, to allow the pressurizing gas to flow through check valves into the propellant tanks. Then the propellant valves in the engine itself are opened. If the fuel and oxidizer are hypergolic, they burn on contact; non-hypergolic fuels require an igniter. Multiple burns can be conducted by merely opening and closing the propellant valves as needed, if the pressurization system also has activating valves. They can be operated electrically, or by gas pressure controlled by smaller electrically operated valves. Care ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
