The paper presents an application the research results previously done by group on the influence of technological parameters to the deformation angle and finish surface quality in order to choose technology parameters for the incremental sheet forming (ISF) process to produce products for the purpose of rapid prototyping or single-batch production, including all steps from design and process 3D CAD model, calculate and select the technological parameters, setting up manufacturing and the stage of post-processing. The samples formed successfully showed high applicability of this technology to practical work, the complex products with the real size can be produced in industries: automotive, motorcycle, civil...

Correction System

The system of route correction of an unmanned aerial vehicle (UAV) is considered. For the route correction the on-board radar complex is used. In conditions of active interference, it is impossible to use radar images for the route correction so it is proposed to use the on-board navigation system with algorithmic correction. An error compensation scheme of the navigation system in the output signal using the algorithm for constructing a predictive model of the system errors is applied. The predictive model is building using the genetic algorithm and the method of group accounting of arguments. The quality comparison of the algorithms for constructing predictive models is carried out using mathematical modeling.

Rescue System

The article presents brief results of the analysis of the subscriber segment of the international space search and rescue system COSPAS-SARSAT. Proposals on the nomenclature of emergency subscriber emergency terminals and direction finders are presented, which are necessary for development and production in batch production in Russia, in order to prevent a backlog in this area and to implement the import substitution program. The recommendations are developed taking into account the materials discussed at the working technical groups, the Joint Committee and the COSPAS-SARSAT Council in recent years, as well as the results of the technical analysis of the nomenclature of terminals produced and developed by foreign companies. In addition, the development of recommendations takes into account the main current and prospective directions for the development of Russia's economy and industry.
