The paper investigates the capabilities for increased productivity, reduced lead times, and higher product quality with the concerted use of CAD/CAM/CAE and software platforms for workgroups. For the purposes of this report, the design of the reusable training-practice mortar round for short distance firing is used as an example.

The aim of the study is to find out the performance of highly skilled archery athletes in different variants of annual training. The object of research is the system of training highly qualified athletes in archery. The subject of research is thebuilding annual training of highly skilled athletes in archery. Methods of research – theoretical analysis and generalization of literary sources;analysis of documentary materials; methods of mathematical statistics. Scientific novelty. With this work, we will be able to investigates the variability of approaches to construct an annual macrocycle using the example of 2007–2018. The practical significance of our study is research a development that can be used when designing a training system for highly skilled archers. Results. In the course of the study, options for constructing annual training were identified. The distribution was based on the number and orientation of the competition. In the first variant of construction dominated by control competitions. The best results were in 2008, when Victor Ruban won the gold medal at the XXIV Olympiad Games, and the men's team stopped a step ahead of the bronze medal and took 4th place. In the second embodiment, control and qualifying competitions prevail. It should be note that this variant of construction made it possible to perform successfully at the I European Games. However, the focus was on annual training, which did not allow the license to play for the XXXI Olympics men's team. In the third embodiment, qualifying competitions prevail. The performance of competitions during this period decreased somewhat. In particular, for the women's national team was a successful performance at the European Championship.

The article explores contemporary computer tools for calculating stress-strain of mechanisms and elements for heavy weapons and machine guns. The article is intended to aid the knowledge and skills requirements in the future work of engineers and constructors in machine engineering and weapon systems.
