Abstract
This work aims to map hydraulic and pneumatic systems applications in the military machinery and equipment. There are a lot of machinery and equipment used by the Army that use hydraulic and pneumatic systems due to their advantages. Each type of power system has its own advantage, in the case of fluid power systems, we can develop high forces through small devices (good power density) and high response velocity due fast acting with high accelerations. Besides we can also have energy storage capacity through hydropneumatics accumulators, self cooling properties, best reliability in hard work and flexibility of installation of their actuators through a combination of hose and low weight actuators. The Brazilian Army has a constant concern to modernize their technological equipment in order to keep up with other countries and to increase production capacity. This modernization will increase effectiveness, efficiency and capacity of the Army machinery and equipment. In consequence of this modernization the Army will be able to fulfill its missions in the best possible way. As a methodology for this work, various databases of scientific papers, patents and research reports were used in order to verify previously developed solutions and monitor the design evolution of mechanisms and hydraulic and pneumatic systems used by the Army. By means of a classification of applications, it is intended to show the evolution of equipment and technologies used and to identify where the applications of fluid power systems best suit, besides identifying product ideas and characteristics desirable that have not yet been developed as a way of viewing future products. As results, we present a new viewpoint about military machinery centered on three main modular systems: mechanisms, power drive system and control system. Highlighting the power drive system, where we have focused the current state of hydraulic and pneumatic systems and shown how they are being used in machinery and equipment used by the Army. It can be concluded that the best application depends on the different scenarios and the results of this work can also serve as a guideline for future research and improvement of military equipment and machinery taking into account new aspects of energy efficiency.
