FIELD: thermal investigations. SUBSTANCE: voltage drop Usi is measured across active part of each simulator, then voltage drop Ufei is measured across passive part , current through each simulator is found from predetermined dependence Isi = f(Ufei) and active resistance of each simulator is determined from equation Rsi = Usi/Isi. Unserviceable simulator is determined by comparing measured active resistance of each simulator Rsi with its rated value Rri. Entire measurement cycle is periodically repeated in the courser of assembly. EFFECT: enhanced precision of determining emergency condition, preventing failure of simulator assembly. 3 dwg
