Space simulator
Angelantoni Industrie

ACS space simulator delivered to the ISRO Satellite Centre in Bangalore, named HVT400MC, is one of the two largest space simulators existing in Asia and the most technologically advanced in the world.
The simulator consists in a stainless steel structure that encases the area in which the tests are conducted, a cylindrically shaped chamber 7 m in diameter and 11 m long.The system is fitted with 4 cryogenic pumps that generate the high vacuum required with a pumping capacity of 60.000 L/sec each.
Temperatures inside the cryogenic pumps drop to 10° Kelvin, corresponding to -263°C, through the use of helium, while the vacuum value reached is 10-7 mbar.The thermal system includes 15 independent circuits capable of reproducing the conditions that surround satellites when in space. The circuits gradually reproduce the entire range of temperatures experienced in space, from those on the side that is lit by the sun to those on the dark side, namely from -180°C to +180°C. Cooling is provided by liquid nitrogen stored in 4 large containers (22 meters tall) that can stock up to 500,000 liters of nitrogen.
