چکیده
The space industry is seeking new solutions for the development of lightweight, inexpensive and easy-to-manufacture on-board communication payload devices. One proposed technologies additive manufacturing (AM) polymeric materials that are subsequently metallized. devices developed using this technique must be operational in particular environment conditions. In work we study integrity filters made by against extreme conditions mechanical stress, temperature power management as described standard European Space Agency (ESA) satellite payload. To carry out qualification space, two types X-band with identical frequency responses have been designed manufactured: a classic H-plane waveguide cavities filter, three on surface-mount technology (SMT). Two SMT low height rectangular filters, while third one high circular filter. This selection was intended to verify AM offered good results regardless topology. vibration tests were performed: sinusoidal sweep random vibration. These emulate transport launching Furthermore, it measured natural its variation after being exposed order evaluate their physical integrity. thermal analysis performed emulating profile experienced during working Then, handling carried out. secondary electron emission yield material (metallized polymer) firstly measured. levels, location at which multipactor discharge would occur analyzed both, low-height standard-height, filters. Finally, both subjected those under vacuum conditions, check if said discharges occurred. stress prove can survive hard operation commercial payloads. report levels handle without risk radiofrequency (RF) breakage. All these allow fully qualify spatial applications.

متن کاملLaser beam welding of titanium additive manufactured parts
In this paper the joinability of titanium Additive Manufactured (AM) parts is explored. Keyhole welding, using a pulsed laser beam, of conventionally produced parts is compared to AM parts. Metal AM parts are notorious for having remaining porosities and other non-isotropic properties due to the layered manufacturing process. This study shows that due to these deficiencies more energy per unit ...
