- Plný úväzok
- Prototyping of the End-Effector: Construct a laboratory prototype that embodies the conceptual design, using materials and components resilient to space conditions, including extreme temperature fluctuations and vacuum.
- Analyze Mechanical and Thermal Behavior of the End-Effector by Simulations: Leverage simulation tools for in-depth analysis of the end-effector's performance, focusing on stress distribution, thermal management, and the interaction with different spacecraft surface materials.
- Testing of the End-Effector Behavior: Implement exhaustive testing to evaluate the welding quality on various spacecraft surfaces in vacuum, ensuring compliance with ISO 14555 standards.
- Achieve High-Quality Joints on Varied Spacecraft Surfaces: Through careful design, testing, and optimization, ensure that the end-effector can produce welds that meet or exceed the quality requirements across a diverse range of conductive and non-conductive surfaces encountered in spacecraft.
- Metallographic and Metallurgical Analysis of Weld Joints: Conduct comprehensive analyses using advanced microscopy techniques to assess the microstructure, phase composition, and integrity of weld joints, providing insights into the quality and durability of the welds.
- Mechanical Testing of Weld Joints: Perform mechanical testing, including tensile, shear, and fatigue tests, to evaluate the strength and reliability of welds produced by the end-effector on different spacecraft materials.
