Description
Изобретение относитс к исследователь ским установкам, в частности к установкам дл исследовани двигател с внешним подводом тепла, особенно дл двигателей, работающих по упрощенному циклу Стир- линга.The invention relates to research facilities, in particular to installations for the study of an engine with external heat supply, especially for engines operating on a simplified Stirling cycle.
Известны установки дл испытани Двигател с внешним подводом тепла, содержащие корпус с цилиндром, в котором размещен поршень, кинематически св занный с валом отбора мощности, соединенным с обратимой электромашиной, и раздел ющий внутреннее пространство цилиндра на две полости переменного объема, сообщенные между собой через газовый тракт, в кото ром размещены нагреватель и основные холодильник и регенератор, и резервуары рабочего тела с высоким и низким давлени ем, подключенные к одной из полостей че рез запорные органы l.Installations for testing the Engine with an external heat supply are known, comprising a housing with a cylinder in which a piston is located, kinematically connected to a power take-off shaft connected to a reversible electric machine, and dividing the inside of the cylinder into two cavities of variable volume communicated with each other through a gas cylinder. the path, in which the heater and the main refrigerator and the regenerator are located, and the working fluid tanks with high and low pressure, connected to one of the cavities through the stop valves l.

Однако в таких установках затруднено исследование регенераторов ввиду того/ что величины методологических ошибок имеют тот же пор док, что и величины замер емых параметров (что предопределено мальгм средним давлением цикла). Сн тие ука занных ограничений св зано со снижением термонаир женности элементе конструкции и исключени паразитных тепловых потоков по корпусу двигател . Кроме того, исследование рабочих процессов с изменением рабочего тела двигател св зано с соответствующим изменением величин термонапр женности элементов газового тракта.However, in such installations it is difficult to study regenerators due to the fact that the values of methodological errors are of the same order as the values of the measured parameters (which is predetermined by the average cycle pressure). The removal of these limitations is associated with a decrease in thermal irregularity of the structural element and the elimination of parasitic heat fluxes through the engine block. In addition, the study of working processes with a change in the working fluid of the engine is associated with a corresponding change in the thermal stress values of the elements of the gas path.
