The Use of Optical Metrology in the Aerospace Industry GOM
Component Testing Aerodynamics of Sample Return Capsule
· Devices to return rock or dust samples from space are so called sample return capsules
· Return capsules are designed to protect a sample container, which is stored inside the capsule, from the extreme heat produced during the re-entry into the atmosphere
· The return velocity of approximately 45000 km/h (13 km/s) must be drastically reduced before the capsule enters lower layers of the atmosphere to prevent overheating
· A blunt geometry of the capsule is thus mandatory to produce enough resistance for velocity reduction in higher atmosphere layers

· A blunt geometry of the capsule is thus mandatory to produce enough resistance for velocity reduction in higher atmosphere layers
· Blunt geometries are tending to be aerodynamically instable and are starting to swing, especially when decelerated to the speed of sound and below
