Abstract

A variant of the parametric representation of a single use complex product in the process of its creation during testing is described, when structural failures of the product or its component parts according to one or more parameters specified in the technical specification, requires the implementation of modifications is required, leading to changes in general set and repetition trials, however, it is possible to reduce the volume of tests by taking into account a priorii information. This is especially true, while ensuring the reliability of complex space products of single use, the components of which pass the first stages of ground tests, and then as part of complex space products the stages of flight tests. The structural failure of any component of a space product during ground testing must not have the effect of occurring during flight tests as if it had been part of the product. Meanwhile, the completion of the component element of a singleuse product, the structural failure of which occurred at the stage of flight tests in the product, and the evaluation of its effectiveness, can be carried out at the stage of ground tests, in the case of a complex product consideration in parametric form. It can significantly reduce the cost of flight testing of a complex product, in the case of the product composite element effective refinement at the stage of ground testing, without a significant (temporary) reduction in the overall reliability of a single use complex product.
