The engineering qualification model (EQM) of the new Russian communications satellite Express-AMU is currently undergoing a series of mechanical tests at JSC ISS Reshetnev Company, the leading Roscosmos enterprise for the development of communications spacecraft.
The purpose of the tests, conducted in several stages, is to confirm the satellite structure's ability to withstand extreme loads arising at all key stages of its life cycle, from transportation to orbital insertion.
During the tests, specialists simulate a wide range of impacts:
- dynamic and static loads during transportation by various modes of transport;
- intense vibrations characteristic of the launch and flight of the launch vehicle;
- shock impulses that occur when the mechanism separating the spacecraft from the upper stage is activated;
- acoustic loads ("roar") accompanying the launch of the launch vehicle.
According to the Roscosmos press service, successfully passing these tests will be an important step toward creating the flight model of the satellite and will ensure high reliability of its operation in the conditions of outer space.
