Development of a Dimensionally Stable Lightweight Structure for the LISA Pathfinder Science ModuleLISA Pathfinder - SCM
 
Measuring Systems: TRITOP
 
Keywords: thermo-elastic, climatic chamber, structure deformation
 
The Science Module Structure of LISA Pathfinder - the precursor for ESA's ambitious LISA mission to detect gravitational waves - is designed to fulfil extremely stringent thermo-elastic distortion requirements. The emphasis of this abstract is the accurate measurement of the thermo-elastic performance in a dedicated distortion test.
3D Digitizing of the X-38 Space Vehicle3D Digitizing of the X-38 Space Vehicle
 
Measuring Systems: ATOS, TRITOP
 
Keywords: Computation Fluid Dynamics (CFD), CAD Comparison
 
During the development of the X-38 some computer simulations are used to allow an optimization of the design. Therefore it is very important that the form of the actual vehicle matches the form of the CAD construction. For this reason the actual vehicle has to be digitized with high accuracy and high data density. In this application note, we show how the digitizing was done with ATOS and TRITOP and how the data was treated to match the needs of NASA.
