PURPOSE: A rig test apparatus is provided to set an accurate exhaust heat and pressure and allow for a fatigue test under a wide variety of operation conditions, while preventing accident caused due to an explosion. CONSTITUTION: A rig test apparatus(20) comprises a pressure unit for generating a high pressure exhaust pressure, a heating unit for generating a high temperature exhaust heat and a control unit for controlling the pressure unit and heating unit. The pressure unit includes a cylinder head(23) and a cylinder block(24) arranged at a side of a main body(21) having a chamber(22), which is configured such that a high air pressure is supplied from an air compressor(26) through an air nozzle(27). The cylinder block has a coolant passage(25) for supplying coolant for preventing overhead of the apparatus. The heating unit includes a high frequency heater(40) arranged at an outer periphery of an exhaust manifold(30) mounted in the exhaust side of the cylinder head; and a pressure regulating valve(60) arranged at an end of the exhaust manifold so as to regulate the exhaust pressure. The control unit controls operation of a valve(28) for controlling the amount of air being supplied to the air nozzle from the air compressor, high frequency heater and the pressure regulating valve.
