The successful development of small commercial turbogenerators for automotive and other applications presents a major economic challenge. Current aerospace turbogenerators in the 60 kilowatt power range sell for around $500 per kilowatt. Volume automotive turbogenerators prices must be $30 per kilowatt, or less — a 94% reduction. Turbogenerators for aerospace applications have drastically different requirements on almost all important criteria from automotive turbogenerators. The production of commercial turbogenerators requires a radically different organizational setting, mindset, and overhead structure from that necessary for the aerospace industry. Ground up designs which take an integrated approach to material selection, method of operation, fabrication techniques, supplier base, assembly methods, and low cost overheads will be necessary for commercial success. Significant innovation and simplification, and the natural effects of high volume production are also required. Success will likely require lean, agile, innovative, and specialized organizations.

The existing radar and radio navigation facilities sometimes do not satisfy the increased requirements for the accuracy, efficiency and reliability of information support for navigation in the organization of movement in the rough waters of the Arctic region in difficult climatic and meteorological conditions. This article offers a comprehensive approach to the information support of navigation based on technical solutions that significantly increase the capabilities of navigation tools in the rough waters of the Arctic zone. The proposed approach to the creation of fundamentally new high-precision information tools for solving a wide range of new tasks in the Arctic zone based on radar provides a higher class of accuracy and functionality compared to those currently used. The technical requirements for radar facilities are defined and the use of a new generation of highly informative multifunctional coastal radars in combination with new mobile pilotage terminals is proposed. The application of the proposed technical solutions and the principles of building navigation systems will significantly increase the safety and efficiency of navigation in waters with increased complexity of navigation organization. The proposed approaches will ensure the solution of the such tasks as: monitoring of air, surface and ground space, local navigation system for safe navigation of ships, helicopter flight, landing of helicopters on offshore drilling platforms and ground airfields, mooring of vessels to drilling platforms and terminal berths. It also support monitoring and dispatching of ship traffic in ports and the area of responsibility of terminals, including monitoring the position of ships at anchorage. Will be sufficient simplify high-precision operational assessment of the ice situation and the weather in the radar area of responsibility, protection of offshore drilling platforms and territories of onshore terminals, information support of means of protection against potential terrorist threats.

Producing class S propellers and water jet impellers presents serious challenges for propeller manufacturers. To overcome these challenges and consistently manufacture propellers with superior quality, an integrated approach was adopted when developing and implementing a process for Computer Numerically Controlled (CNC) machining of propeller surfaces. Highlights of this process are: (1) CNC machining of all blade surfaces; extreme surface blending, (2) CNC machining to final form & finish without hand grinding and (3) high precision, better than class S. This paper will describe various challenges encountered in the production of CP propeller blades and how these challenges were overcome in order to produce accurate CP propeller blades which exceed class S tolerances.

The structure of the complex of design procedures of the complex of design procedures of the system of accounting requirements for assembly in design of manufacturing methods of mechanical processing is formed in the article, and the mathematical and methodological implementation for the realization of the integrated blocks of design procedures of this system is considered. The employment of this integrated approach within the framework of the existing multi-nomenclature production allows to reduce the assembly time of high-precision products and the number of incomplete parts (work-in-process).

In current conditions, the necessity to produce many high-precision tooling and machines has increased many times over. That is why the improvement of such products manufacture becomes of paramount importance due to the increasing requirements imposed on them. The existing approaches to ensuring the quality and accuracy of high-precision products are not universal and not always can be implemented when producing high-precision goods. For a comprehensive solution to this problem, the authors proposed using an integrated approach – the complex of formalized design procedures of the system for accounting of the requirements to the high-precision products assembly when designing the manufacturing methods of machining. However, for the establishment of relations between the process design and designing preproduction of multi-product manufacture, the transition to the assessment of the production manufacturability of goods and deeper integration of this system into the structure of the system of automated sequencing of manufacturing methods, it is necessary to search for ways to improve the existing approaches of the developed system. The paper considered in detail the enlarged block of design procedures for the analysis of requirements to the assembly of high-precision products, since this stage is directly related to the designing preproduction, and the initial data obtained in the course of its implementation ensure the quality of choice of rational manufacturing methods of machining of parts. The authors propose the techniques to improve mathematical, methodological, and algorithmic support of this enlarged block implementation. The introduction of the proposed solutions will allow performing effectively the design dimensional analysis of a high-precision assembly unit in an automated mode and forming a set of assembly requirements, which, as a result, will allow ensuring the expansion of digitalization of the process design and designing preproduction and the transition to intelligent production systems.
