Princip setrvačníku je znám několik tisíc let. Velmi dlouho se setrvačník využívá ke stabilizaci otáček nejrůznějších točivých strojů, včetně automobilů. V poslední době objev vysokoteplotní supravodivosti umožnil konstrukci setrvačníků s levitačním závěsem, které slibují využití pro stabilizaci parametrů rozvodných elektrických sítí nebo k akumulaci elektrické energie., The principles of gyroscope have been known for thousands years. For a long time gyroscopes have been employed for stabilization of revolution speed in various rotational machines, including automobiles. Recently, the discovery of high temperature superconductivity enabled the construction of flywheels (gyroscopes with a levitation suspension) that promise a wide use in stabilization of a number of parameters of the electric energy distribution network and in electric energy accumulation., Miloš Jirsa., and Obsahuje bibliografii
Stealth F-35 multi-role fighters are high-performance weapon and sensory systems allowing for a penetration into an A2/AD enemy zone guarded by radars and guided missiles. The Czech Republic’s closest zone affected by the A2 / AD concept is Poland largely covered by A2/AD systems from the Russian Kaliningrad region. Following the INF Treaty termination in 2019, it has partially expanded into the Czech Republic, using particularly 9M729 (SSC-8) long-range ground-based guided missiles of Iskander system. Thus, the technical equipment of mechanized (7th MB Hranice) and motorized (4th RFB Žatec) units of the Czech Armed Forces concentrated in the vehicle fleets can be put out of action in a single precise strike. That is one of the reasons why in September 2019 Poland, respecting the North Atlantic Treaty (NATO) commitments, decided to procure 32 F-35A fighters. Also, other NATO members can deploy fighters of this type in the area and therefore appropriate measures shall be implemented in the Czech Armed Forces as well to support and fully develop the tactics of the NATO combined air-ground operations.
The year of 2019 will enter history as a relatively sharp end of the West’s attempt to globalize the world. Nevertheless, the endeavor to connect the mankind into one big society linked by mutual communication, information, economic, cultural and ecological bonds has not come to an end; it is just that the democracy of the West will no longer be employed to achieve that. The other civilization circles have not accepted it yet and to ''civilize'' others they will make use of their power approaches that are not only of a social character but also of a physical one. The most developed concept is the A2/AD (Anti Access/Area Denial) zones establishing focused also on the Western countries including the Czech Republic. It is being developed mainly by the Russian Federation and China.
