In previous works, we developed a mathematical model of the internal ballistics of a muzzle-loading smooth-bore gun and made its software implementation. Model testing has shown that our understanding of the intra-ballistic processes of this type of weapon requires serious correction. One of the defining parameters is the geometry of the powder grain. This paper reviews the information available in the literature on this issue. It is concluded that in most works on the geometry of the grain is not reported, due to the fact that the grains had some kind of intuitively justified form. Based on the analysis of the technology for producing grain gunpowder in the first half of the 19th century, it was concluded that this shape is similar to the shape of pebbles on the beach.

Sarapul timber industry enterprise – one of the oldest and largest forest enterprises in Udmurtia in its history has been reorganized more than once. In the period from 1938 to 1949 it was divided into several smaller farms, of which the fleet had only the Dulesovo mechanized forestry station. The source base on the work of this fleet during the war years is extremely limited. In the article, the reconstruction of the work of the fleet is carried out on the basis of orders for the personnel of the economy. The source falls under the law on the protection of personal data, which establishes 75 years, only after which, in 2020, the documentation became publicly available. At the beginning and end of the war, the fleet of the Dulesovo mechanized forestry station included a boat № 35 (30 hp) and one shitik (orlyana). An analysis of orders for wartime personnel showed extremely limited use of the existing fleet in the economy. Apparently, it was only by spring water that the ships were temporarily transferred to the Sarapul timber base for rafting, the rest of the time they were used for service and traveling purposes.

At the moment, unmanned aerial vehicles are an actively developing system of weapons, possibly forming into a new branch of the military in the near future. The absence of a pilot allows not only to reduce the weight and dimensions of the apparatus, but also to reduce its cost. And the operator on the ground gets the opportunity to perform much more daring dangerous actions than manned vehicles. The paper provides an overview of the features and results of the combat use of unmanned aerial vehicles in recent armed conflicts. The description of the Turkish UAV “Bayraktar” and the ammunition carried by it is given. The results of its application in the conflict in Nagorno-Karabakh, the operation “Spring Shield” and the civil war in Libya are presented in a concise form. A description of the “Tomahawk” cruise missile and the results of its use in Syria are given. The work was written on the basis of publicly available electronic media.
