Theoretical and experimental substantiation of application of method of permanent expansion for evaluation of static strength margin of steel cylinders have been presented. Common deformation curve and deformation plasticity theories are used. A possibility is provided for justified designation of a maximum allowable coefficient of permanent expansion used at periodic inspection of the cylinders.
В статье приведено описание схемы, конструкции и программы для измерения скорости вращения двигателя квадрокоптера. Основное отличие от существующих прототипов [1] – использование инфракрасного датчика отражения, что позволяет безопасно проводить измерения и не задействовать конструкцию моторов. Вторым ...
В статье приводятся описание схемы и конструкция устройства для измерения величины постоянного магнитного поля. Основное отличие прибора от существующих прототипов заключается в использовании модуля UART-USB , что уменьшает затраты на автоматизацию и визуализацию измерений. Регистрацию магнитного поля выполняет ...
Выяснена одна из основных причин феномена "теплого" лампового звука.Показано что этот феномен является одной из акустических иллюзий, связанной с особенностями восприятия природных звуков.Статья может представлять интерес для широкого круга читателей.

Вал двигателя сделан заодно с наклонным диском, кинематически соединённым с поршнями, усечёнными по эллипсу. Нагнетательные и рабочие цилиндры сгруппированы вокруг вала и ориентированы параллельно ему. Это даёт высокую удельную мощность и снижает давление поршней на боковые стенки цилиндров.
The physical principle of the work ofVan de Graaff generator, until now, is not explained, but there is only a technical oscillator circuit. There are no calculated relationships, which give the possibility to calculate this generator. In the article physical oscillator circuit and its ...
The concept of scalar-vector potential provides for the dependence of electrical pour on the moving charge from its speed. In this concept the charge is not the invariant of speed. Up to now only indirect experiments, connected with the appearance of electric pulse with the space thermonuclear explosions ...
It is customary to assume lasers as quantum generators. But this name does not correspond to the principle of their action. Such generators present the phased lattices and are subordinated to the known laws of radio engineering. Physics of the work of such generators describes the ...
From an energy point of view its transfer on the direct current is the most advantageous method of the transfer of the large volumes of electric power up to the great distances. However, up to now there does not exist such direct-current generators, which are capable of generating the necessary level of power with the ...
From the times of Lorenz and Poincare the Lorentz force was introduced as experimental postulate, and up to now therewas no explanation of its physical nature. in the article is proven that the Lorentz force is the consequence of the dependence of the scalar ...
In the article new approaches to the solution of the problem of the propagation of electrical energy fluxes in thematerial media and the long lines are examined. The electrodynamics of plasma is examined and it is shown that theabsolute value of the vector of poytinga ...
At the basis of reactive thrust the law of momentumconservation lies. If from the closed system in somedirection is ejected work substance, for example mass, thenthere is always a recoil momentum, which is reactive thrust. Inthe photon engines work substance are electromagnetic ...
In the article is described the ferroelectrictransformer, which in contrast to the transformer with theferromagnetic of cores can work at the high frequencies. Suchpreviously transformers were not known. This opens prospectsthe creation of wide-band ferroelectric ...
The Homopolar induction was discovered byFaraday more than 200 years ago, but also up to now thephysical principles of the operation of some constructions ofunipolar generators remain obscure. There were the attemptsto explain the work of such generators by action on the ...
Ferrite is soft-iron material and therefore it cannot be magnetized. However, the rings, made from ferrite, can be magnetized in the assigned direction. This special feature of the magnetization of such rings did not have, until now, of physical substantiation. In the article are examined the processes ...
Physics of the work of transformer with the ferromagnetic core is examined. The new types of transformers withthe ferroelectric cores are proposed, and physics of the work of such transformers is also examined. Keywords: transformer, ferromagnetic material, ferroelectric, ...
