Exploring the application of digital twin technology in the field of artillery equipment protection

This paper addresses the problem that artillery condition assessment work is still stuck in the way of regular maintenance and after-the-fact repair, which makes it difficult to achieve accurate equipment protection, etc. Taking a typical artillery loading system as the research object, this paper uses simulation and experimentation to carry out research on loading system condition assessment by constructing a digital twin system framework for artillery equipment condition assessment, studying the construction of twins, data transmission between physical entities and twins and other key technologies, and providing a reference method for achieving accurate artillery maintenance and protection.

Simulation study on erosion of barrel under thermal-mechanical-chemical coupling environment

Artillery is known as the “God of War”. When the ballistic performance of the barrel is reduced to the allowable value specified by the index due to erosion and wear, the life of the barrel is terminated, and the artillery equipment completely loses its combat effectiveness. The erosion and wear of the barrel involves many factors such as temperature, mechanics, chemistry. In this paper, based on the theory of internal ballistics and heat conduction, the temperature gradient distribution law of the inner wall of the barrel during the firing process of large-caliber artillery is simulated and calculated. Combined with Fick’s second law and the theory of metal phase transition, The relationship between the [C] content in the thermochemically affected layer of the barrel and the number of firing, the relationship between the thickness of the thermally affected layer and the explosion temperature of the propellant and the temperature of the inner wall were quantitatively analyzed. On this basis, the anatomical analysis of different parts of the barrel after firing verified the accuracy of the erosion model, quantitatively revealed the barrel erosion mechanism, and clarified the direction for the life improvement of large-caliber artillery barrels.

Key technology and application of gun agile optimization design based on dynamic simulation

The new generation of artillery equipment is showing the development trend of lightweight, long-range, intelligent et al. However, the traditional development mode based on physical prototype test cannot meet these needs of equipment development. In the development, there are some problems, such as lack of systematic guidance in the overall design scheme, low degree of digitalization and parameterization of the model, and long period of serial iterative development, which need to be solved by optimization design. Parametric modeling technology, hard point driven template model technology and structural optimization design technology are briefly introduced, which are the foundation of equipment optimization design. These key technologies, combined with the overall scheme design, chassis system design and ammunition loading timing optimization design of a large-caliber tracked self-propelled gun, showing the basic development route of artillery performance improvement. The optimization design of artillery type equipment are summarized in recent years, which provide reference for other similar work.

SUGESTIONTS FOR LABORATORY EQUIPMENT COMPOSITIONS FOR DETERMING THEIR CHARACTERISTICS

The world experience of creating models of weapons and military equipment, including artillery ammunition, involves numerous tests during their life cycle, checking both the products as a whole and their component.
 The article is aimed at analyzing the types of tests of artillery munitions and developing proposals for listing the necessary laboratory equipment to assess their characteristics.
 When testing artillery munitions, about 40 types of resistance tests (changes in climatic factors, strength and resistance to mechanical factors, etc.) should be carried out:
 environmental temperature change test; high humidity test;
 low temperature test elevated temperature test;
 atmospheric condensation test (ynia, dew); rainfall (rain) test;
 mold test;
 test for static effects of sand and dust; dynamic sand and dust testing;
 rapid pressure change test;
 a test for the effect of reduced atmospheric pressure; sine wave strength test;
 single-effect mechanical impact strength and durability test; strength test with repeated mechanical impact;
 test of stability at rotation;
 durability test during transport in packaged form.
 Thus, in order to improve the quality of the tests, it is necessary to define the types of tests (checks) as well as the composition of laboratory equipment for the evaluation of the characteristics of artillery equipment, namely, the climatic chamber, thermobarochamber, sand and dust chamber, mushroom-forming chamber, impact copper, transport simulation stand
 Findings. The article analyses main types of tests of artillery munitions and offers modern laboratory equipment, which should be used to assess their characteristics.

August 1944 in Constanța. The Case of Rear Admiral Horia Macellariu

This paper focuses on the role of the Romanian Royal Navy and of the personality of the most capable commander of its maritime forces during the campaign in the East, in the 23 August 1944 decisive moments – Rear Admiral Horia Macellariu. In the context of the country’s exit from the alliance with Germany and of the political-military changes, and under the impact of the proclamation issued by King Mihai I, in Constanța, the problem for the commanders of the Royal Navy was very sensitive: the detachment from the RomanianGerman mixed command. The situation was characterised by uncertainties, the ships of the Maritime Naval Force being interspersed with many more German ships, which had a superior artillery equipment. Rear Admiral Horia Macellariu, the Commander of the Navy and directly responsible for the fate of the crews, was also under the Commander of the 9th Infantry Division. His orders, from the General Staff and the Naval Staff, to disarm or force the German troops to withdraw Southward, in Bulgaria, required special tact and diplomacy. The excellent working relationship between Rear Admiral Macellariu and German Admiral Helmuth Brinkmann helped to avoid a bloody confrontation, which could prove disastrous for the port and the city of Constanța After the withdrawal of the Germans, appointed Superior Commander of the Dobruja territory, Rear Admiral Horia Macellariu had the ungrateful task of receiving the Soviet troops, whose generals and admirals considered the Romanian Armed Forces defeated and treated them as such. A series of pressures followed, doubled by insults and hostile attitude on the part of the Soviet occupant, culminating in the forcible takeover of Royal Navy ships on 5 September 1944.

26 dywizjon artylerii ciężkiej w latach 1937–1939

Artykuł opisuje historię mało znanej jednostki artylerii Wojska Polskiego z okresu międzywojennego – 26 dywizjonu artylerii ciężkiej. Jednostka ta powstała jesienią 1937 r. w Skierniewicach na obszarze Okręgu Korpusu nr IV Łódź i została bezpośrednio podporządkowana dowódcy 26 Dywizji Piechoty. Powstanie 26 dywizjonu artylerii ciężkiej było jednym z elementów zwiększania siły ogniowej związków taktycznych piechoty polskiej. Jednak braki w sprzęcie artyleryjskim spowodowały, że do 1939 r. dywizjony artylerii ciężkiej sformowano jedynie w kilku dywizjach piechoty, w tym w 26 Dywizji Piechoty. Zamiast planowanych trzech baterii 26 dywizjon artylerii ciężkiej miał jedynie dwie baterie liczące po trzy działa (w pierwszej baterii armaty 105 mm, a w drugiej baterii haubice 155 mm). Omawiana jednostka została zmobilizowana w marcu 1939 r. Pomimo wielu trudności i braków w wyposażeniu mobilizacja odbyła się sprawnie, a braki uzupełniano w kolejnych tygodniach. W maju 1939 r. 26 dywizjon artylerii ciężkiej został przewieziony koleją do Wielkopolski (wraz z całą 26 Dywizją Piechoty) i podporządkowany dowództwu Armii „Poznań”. W wojnie polsko-niemieckiej wspierał ogniem oddziały własnej dywizji w czasie walk nad Bzurą. W ich trakcie jednostka została rozbita, a większość żołnierzy dostała się do niewoli niemieckiej.

The Mendel Journal

IN NATURE for December 30, 1909 (p. 252), there appeared a review of the first number of the Mendel Journal, by “E. H. J. S.” He also, in the same review, reviewed the current issue of Biometrika. I pass no comment upon the questionable fairness of having two such diametrically opposed journals reviewed by the same person, who, if we may judge by certain statements in the review, is himself a biometrician, or very friendly disposed towards them. I am alone concerned in dealing with your reviewer's misinterpretation and imperfect reading of certain articles of mine written under the nom de plume of “Ardent Mendelian.” He accuses me of “adopting a tone calculated to be offensive to biometricians,” and as an instance he cites the following sentence:— “We may further infer, therefore, that the discipline of the army1 is very severe, and perhaps this may throw some light upon the constant reappearance of the figure 0.5 in relation to the size of some of its artillery equipment.” 2 Your reviewer interprets this as a “serious charge of faking” directed against biometricians. I do not know upon what plan he writes his reviews or whether he reads sufficient of the article he reviews to grasp properly its tone and meaning. Nothing was farther from, my intention than to impute, want of integrity to any biometrician, notwithstanding some bad examples which they themselves have set, when they deal with Mendelians. Had your reviewer but read a few lines lower down (p. 160) he would have found the following chivalrous sentence, describing them:—
