X-rays refer to a type of electromagnetic radiation with a wavelength shorter than ultraviolet light but longer than gamma rays.
X-rays are used in a variety of ways in aerospace research and technology.
-
Non-destructive testing: X-rays are used to inspect the internal structure of aerospace components and materials, such as aircraft engine parts, without causing damage. This is called non-destructive testing.
-
Imaging: X-ray imaging is used to create detailed images of internal structures and systems, such as the human body in medical research or aircraft engines.
-
Satellite and space telescope: X-ray telescopes are used to study celestial objects such as stars, galaxies, and black holes. These telescopes are placed on satellites or on high altitude balloons. Examples of X-ray telescopes include NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton.
-
X-ray spectroscopy: X-rays can be used to study the composition of materials, such as minerals and metals, by analyzing the way they absorb or reflect X-rays. X-ray spectroscopy is used to study the composition of asteroids, comets, planets and other celestial bodies.
In aerospace, X-rays are powerful tools that help scientists and engineers understand the properties and behavior of materials and systems in ways that are not possible with visible light or other types of radiation.
