Disrupting spare parts supply chains can harm the smooth running of an organization. In the case of military vehicles, weapons or other types of equipment used on the battlefield, this is a serious threat that may result in the inability to continue some tactical operations. An ad hoc way to maintain the ability to take action while the appropriate spare parts are delivered and to improve damaged devices may be to produce the damaged components locally. Such a temporary solution is possible for relatively simple elements whose structure, mechanical properties and principle of operation can be determined on a reverse engineering basis. This article describes the concept of alternative solutions for temporarily repairing damaged devices by producing spare parts in mobile specialized production subunits. This paper characterizes the types of 3D printing, contemporary examples of use in foreign armies, priorities of international alliances related to 3D printing, and a case study of repairing an unmanned aircraft by means of 3D printing. Using the experience and knowledge of foreign armies, adapting the possibilities of 3D printing applications to one's own needs, defining legal regulations and creating properly equipped subunits makes it possible to implement the presented concept. Creating conditions for implementing the described concept facilitates the production of a suitable product range in peace, crisis or conflict situations, which may significantly contribute to increasing the level of readiness of the national defense systems.

This paper shows a new strategy for developing of space logistics which is supported by safety engineering for the operational techniques and technologies in space. A new strategy is a very important for developing of space technology because account improvement range and its independence from most terrestrial network failures. The developing space logistics is observable during make of satellites which are ensuring wideranging continuous information flow among people, businesses and governments for assuring of safety and security when terrestrial network connections are disrupted. The main goal in this publication is presenting example of analysis and assessment in an industrial enterprise of space logistics.

W publikacji przedstawiono nową strategię rozwoju logistyki kosmicznej wspieranej przez inżynierię bezpieczeństwa w celu poprawy technik operacyjnych i technologii w przestrzeni kosmicznej. Nowa strategia jest bardzo ważna dla rozwoju logistyki kosmicznej, gdyż uwzględnia poprawę zasięgu oraz jego niezależność od powstałych awarii w sieci naziemnej. Rozwój technologii kosmicznej jest zauważalny przy budowie satelitów, które zapewniają wielopłaszczyznowy, ciągły przepływ informacji pomiędzy ludźmi, przedsiębiorstwami i rządami dla zapewnienia bezpieczeństwa w przypadku powstałych zakłóceń połączeń sieci naziemnej. Głównym celem publikacji było przedstawienie przykładowej analizy i oceny przemysłowego przedsięwzięcia dla rozwoju logistyki kosmicznej.

The fatigue test was carried out on an element of a rotor blade removed from the Mi-2 helicopter. The purpose of the test was to check the fatigue strength of the repaired rotor blade. Metal composite rotor blades have a metal spar in the form of a box and the trailing sections in the form of metallic honeycomb sandwich panels. The trailing sections are bonded to the spar. The repair had been carried out at the point where the trailing section became debonded from the spar at the Air Force Institute of Technology in Warsaw using a methodology developed for carrying out repairs of rotor blades’ damage. All types of the Mi family helicopters are equipped with metal composite rotors blades. Depending on MTOW (Maximum Take-Off Weight) and destination of helicopters, blades differ in dimensions, but their design solutions are practically the same. For this reason, the developed repair methodology can be used for all characteristic rotor blades structures for Mi helicopters. The fatigue test was performed at the Łukasiewicz - Institute of Aviation in Warsaw, using a hydraulically driven fatigue machine. The fatigue test was carried out by performing over 1.1 million load cycles. In repair places, upon completion of fatigue testing, no damage was found.
