Vacuum Testing

We implemented a systemic scientific approach to thermal vacuum development of spacecraft, which integrates the problems of thermal calculations, thermal vacuum tests and accuracy evaluation for mathematical models of heat transfer by means of solving identification problems. As a result, the following factors increase the efficiency of spacecraft ground testing: reducing the duration of thermal vacuum tests, making autonomous thermal vacuum testing of components possible, increasing the accuracy of thermal calculations

Holographic interferometry at around 10 µm wavelengths has many advantages. It offers the possibility of large deformation measurement, while being much less sensitive to external perturbations. We present the state-of-the art of this technique applied to several industrial cases of the space industry. In particular, we demonstrate that the technique is well adapted to measurement of full-field deformation maps of space structures undergoing large temperature variations typical to what they experience in space conditions.
