Design of a recovering system is one of crucial tasks in development work over the rocket projectiles. Properly designed recovering system secures the recovery of testing projectile after firing in undamaged state, what significantly reduces the time and cost of conducted tests. A parachute with its fixation to a projectile which has to be recovered are key components of the recovering system providing its proper operation. Due to the presence of high values of forces acting at the parachute opening and deacceleration of the object the proper selection of suspension is important factor for its efficient recovery. The paper present tests of breaking force for various types of suspensions connecting the object and the parachute.

Abstract: Pyrotechnic materials are one of the types of explosives which are used to manufacture products for military and civil purposes. These materials, in the event of improper storage or use contrary to their intended purpose, may work in an uncontrolled manner. In extreme cases, the phenomenon of a mass explosion involving the entire load, warehouse or transport vehicle may occur, which in turn may lead to significant losses in people or property. History cites many cases in which the explosion of spectacular pyrotechnic products, generally considered harmless, had catastrophic consequences for the life and health of many people. The risks associated with the use of pyrotechnic materials may result, among others, from: negligence on the part of producers, or organizational local authorities, lack or failure to maintain an appropriate level of security by sellers, organizers of mass events and users themselves. Due to the amount of storage in one place, pyrotechnic materials pose a particularly high risk in the places of production and storage. Over the years, there have been many disasters related to the accidental initiation of energetic semi-finished or finished products. This article describes accidents related to the activation of pyrotechnic materials in Poland and abroad. Methods for determining the degree of hazard posed by dangerous goods and examples of the Test Series 6 carried out for pyrotechnic articles are also presented.

The paper presents results of analyses of nine patent descriptions [1-9] of Polish inventions on manufacture technology of primary explosives as lead azide, lead trinitroresorcinate and tetracene, commonly used in military munitions. Five patent descriptions [1,2,7-9] were filed to the Polish Patent Office in years 1935-1975 as unclassified, and the rest patent descriptions [3-6] were applied as classified in years 1954-1962. Announcements about removing secrecy from the classified patent descriptions, were published in the News of the Polish Patent Office in year 2007.

Five patent descriptions of South Korean in-ventions on modular artillery propulsive charges and their basic elements creating such propulsive charges used in 155mm artillery ammunition, were presented. Above inventions were filed to the Korean Intellectual Property Office in years 1992-2019. Three inventions deal with central ignition systems situated inside the modular propulsive charges, and a first of the remaining two relates to double-base smokeless powder charges surrounding the central ignition systems and the second to construction of combustible containers of the modular charges. Presented inventions describe material parameters, geometry of particular elements of the propulsive modules and technologies of their manufacture. ballistics,chemical technology,modular propulsive charges for 155 mm howitzer munitions,central ignition systems,combustible tubes,smokeless powders,combustible containers,Korean inventions

The paper presents results of numerical simulations of heat transfer in the 35 mm anti-aircraft gun barrel wall made of 30HN2MFA steel during firing with combat and practice ammunition. Calculations were made for a single shot and a sequence of seven shots for two types of ammunition 35x228 mm: with FAPDS-T projectile and TP-T practice projectile. The 3150 mm long barrel was divided into 6 zones and in each zone the temperature versus time was calculated along the barrel thickness during firing. The results were compared for both types of ammunition.

The article presents the normative require-ments of the information and communication infrastructure, which also form the standard of its security. Its main considerations focus on the concept of normative infrastructure security requirements as well as their classification and characteristics. The analysis also includes the rules applicable to the public entity's definition of the requirements applicable to infrastructure and its interoperability, as well as the principles already applied when creating and modernizing a specific information and communication infrastructure.
