Identified in the European strategy as a key enabling technology, Additive Manufacturing (AM) has a great potential for industries to reshape, improve and optimize product life cycle, with reduced environmental footprint such as material waste in production. Allowing to meet structural and multi-disciplinary requirements with complex freeform design at a much lower weight than high constrained conventional manufacturing, AM can benefit to numerous space applications. Beside manufacturing process development, software and process control are becoming absolutely necessary to support digitalization of industrial workflow. Dedicated tools such as Computer Aided Design (CAD), Computer Aided Engineering (CAE) and Computer Aided Manufacturing (CAM) were introduced in the digital manufacturing chain; however, their development was driven by standard manufacturing processes. Therefore, appropriate design methods for AM must emerge in a fully integrated end-to-end solution to foster and support the growth and competitiveness of AM. In order to support industrialization of AM, the European Space Agency has selected the Design4AM project, based on a strong partnership between Siemens and Sonaca, for “Development of Design Methods for AM including CAD Design, Optimization, FEM Analysis and Manufacturing features”. On one hand, the project aims at combining within a comprehensive end-to-end process, topology optimization, seamless CAD data flows and predictive process simulation in the Siemens’ NX™ and Simcenter™ environments. On the other hand, the integration of dedicated industrial design workflow within the enhanced Siemens Digital Innovation Platform is validated on a relevant ESA space application provided by Sonaca.

In this paper, our aim is to design and built a lightweight single-piston floating caliper, without compromising the performance. The aim is to design a caliper as simple as possible so that the manufacturing cost would be low. Mounting position can also be varied in this design. To make the caliper lighter it is necessary to remove material, Aluminium 7075 is used as the material, and Asbestos is taken as the brake pad material. To maintain the stiffness the material has to be used in a more efficient way. A computer-aided design model of a brake caliper is created in Solidworks and analyzed for stress and deformation in ANSYS Workbench.

JSC Almaz-Antey in the implementation of the integrated design of complex electronic systems, particularly radar systems, it is required to solve the problem of choosing and optimizing the design parameters of radar devices, including antenna systems, transmitter-receiver paths of radar systems (radar), algorithms and devices for digital generation and processing of radar signals, and radar systems in General. Currently there is no domestic computer-aided design systems that solve these tasks in the complex. Therefore, to solve such problems, the Concern’s enterprises are used by a number of disparate software solutions with their own development and their foreign counterparts. Due to the restrictions caused by the sanctions, the closed scope of the work, as well as in import substitution, highly relevant is the creation of CAD radar, allowing to solve the above problems in a continuous end-to-end loop design. The development of CAD radar conducted by the JSC Almaz-Antey, its subsidiaries and companies with expertise in the design of the radar, using their existing backlog. The paper shows the General architecture of a domestic computer aided design in full cycle end-to-end radar systems (facilities, stations); the concept of five levels of design in the system being developed and the basic requirements for the implementation of this concept. The specificity of the developed computer-aided design system is most pronounced in activity-based scenarios for the use of the designed product in terms of specific air and space attack and defense, and is implemented in the form of functional simulation of the fighting.

To assess the merit of using computer-aided design to model man in three dimensions, many potential problems and advantages must be considered. This paper addresses two related issues. First, it outlines several problems associated with obtaining information on the topic and second, it suggests several ways in which computer man-modelling is superior to traditional workplace design methods.
