How did the faulty aluminum cause NASA’s $700 million satellite to malfunction?
Aluminum is the most common flying metal, and aluminum alloy is widely used in commercial aircraft and military transport aircraft. NASA’s spaceships, space shuttles and the International Space Station also use aluminum for space travel.
NASA uses several layers of gold, titanium, nickel, and aluminum to protect spacecraft, space telescopes, and rockets from space vacuum.
What kind of aluminum does NASA use?
The telecommunications rocket project started in 2011, and NASA-427 alloy started here. It has considerable potential in various automotive applications, such as cast iron wheels, control arms, rotary cutting and other parts.
What aluminum powder is currently used on the US space shuttle? The fuel and oxidant of SLS booster are aluminum powder and ammonium perchlorate, a mineral salt. The dual SLS solid rocket booster provides fuel with a powerful aluminum perchlorate reaction.
Why does rocket fuel contain aluminum? The affinity of aluminum for oxygen is greater than that of most elements, so aluminum is most obvious in aluminothermic reactions(such as thermite). This allows aluminum to burn a lot of heat, which is surprising in what is often considered inert substances such as carbon dioxide and water.
But what metal does the rocket engine use?
Metal alloys are used in today’s liquid rocket engines- Superalloys based on nickel, cobalt and iron nickel systems are widely used due to their high strength and excellent toughness in the range of 252 ° C to 1100 ° C.
Is aluminum rocket OK?
The rocket should be as light as possible, and at the same time bear the huge force generated during the launch. The main engine of most rockets is made of aviation grade aluminum or titanium, both of which are strong but light in weight.
How did the defective materials of a metal manufacturer lead to the failure of NASA’s two satellite launch missions, causing NASA to lose more than 700 million dollars?
The satellite pair covered it when flying in the air and did not separate according to the command.
Hydraulic Extrusion Portland(SPI) is now known as Sapa Profile Company. It is a subcontractor for 19 years and has produced thousands of core test documents. NASA’s orbital carbon observatory and Glory mission failed in 2009 and 2011 respectively.
The Ministry of Justice announced that an Oregon aluminum company had cheated NASA for nearly 20 years, and the mission failed.
Many years of research by NASA’s launch service program has shown that these problems are caused by defective aluminum. Home of Rockets “; pairing”; the satellite covering the Taurus XL rocket mission satellite is due to the lack of metal in SPI.
The company’s employees often modify inconvenient statistical data, violate test standards and standards, forge the speed of equipment used for testing, and use the wrong sample size.
Payload pairing track “; fragile joint”; the data of the rocket manufacturer Orbital Sciences Corporation is based on the error information of aluminum extrusions.
Fragile joint is a structural separation technology starting from ammunition.
Then they forged hundreds of customer test results, improved the company’s profits, and obtained the production base bonus.
The settlement includes all criminal and civil suspicions against Sapa Profiles Co., Ltd. Instead, the company agreed to pay compensation. Dennis Balius, the head of the laboratory, was sentenced to three years’ imprisonment for suspected involvement in fraud. After 2015, the company was prohibited from conducting business with the US government.
