FIELD: physics. ^ SUBSTANCE: stand has a closed secluded circulation loop in which a compressor with a controlled drive, a heater, a test object and a cooler are joined in series by pipes. The stand also has a socket piece for releasing air pressure with a first throttle inside which is connected to the circulation loop between the output of the compressor and the heater, an air pumping line which has a receiver connected through a second throttle to the circulation loop between the input of the compressor and the cooler, where the said receiver is also connected to the output of an extra compressor whose input linked to the atmosphere. ^ EFFECT: reduced energy and financial expenses on testing, provision for dynamic stability of operation of the stand and reproduction of a wide rage of analysed parametres. ^ 1 dwg |
