This research focuses on the load and stability of unmanned aerial vehicles that are as light as possible but with optimal stability functions and increasing the capacity of liquid fertilizer lifted by unmanned aerial vehicles. The increase in lift is rel... see more

A large amount of transport work of a wheeled tractor accounts for the transportation of liquid cargoes by tractor tanks. These tanks are different from road and rail tank containers with no internal partitions that would quench fluid fluctuations. The co... see more

An analysis of main engineering designs for constructions of tank cars for transportation of light oil products is presented in the paper. A special attention is paid to the connection unit of boiler and wagon frame.

The increase of volume and load-carrying capacity of tank cars is an urgent task for improving the efficiency of transportation of liquid bulk cargoes. Variants of the constructive and technical approaches, which allow increasing the specified indices, ar... see more

Every ship project would not be apart from risk and uncertainty issues. The inappropriate risk assessment process would have long-term impact, such as financial loss. Thus, risk and uncertainties analysis would be a very important process in financial fea... see more

The stability of combustible cartridge cases (CCCs) which are extensively used in the high calibre tank gun ammunition is one of the major requirements for their safe handling and storage. The results of stability tests by heating of CCC samples at elevat... see more

Resumo Este trabalho explora a relação entre conhecimento e decisão política ou entre expertise e desenho de políticas públicas, apresentando uma proposta teórico-metodológica para a caracterização de think tanks no Brasil, instituições que operam na... see more

The article is dealt with the results of dynamics research of cistern car while transporting it by the railway-ferry ship in conditions of sea rolling and pitching taking into account the incomplete filling of boiler by the bulk cargo and different wave r... see more

Motion of a train composed of tank cars with various tank incomplete filling level is considered. The analysis of results obtained has shown that if there are tank cars with high incomplete filling in the train, the permissible speed of motion is reduced ... see more
