Development of a prototype of a multi-loop closedbrayton cycle gas turbine power system

Abstract

Aim is to develop the prototype of a multi-loop closed-Brayton Cycle gas turbine power system, whichallows to simulate the cosmic power plant capacity from tens to hundreds of kW intended for food orelectrorocket thermal engines with electric heating, as well as the powerful energy systems of spacecraft for variouspurposes. Creating a prototype model allows to study the joint operation of two gas-turbine power convertersin a single circuit of the total gas heater (which acts as an electric heater), build a control algorithm modulesin transitional processes, investigate the processes of starting and stopping of the modules, as well as select theoptimal control algorithm starting and to identify the fundamental problems in the design and construction of theinstallation in the early stages of development of space multiloop systems. The paper contains estimates of themain parameters of a closed gas turbine plant and the optimization cycle to allow the use of existing sites. Alsopresented an algorithm for calculating. Based on the data as the working fluid was chosen gelieksenonovayamixture with a molar mass of 83.9 kg/kmol, which is an analogue of the thermodynamic krypton. The parametersof a multi-loop closed gas turbine plant and layout version of the two-loop closed-Brayton Cycle gas turbinepower system.
