NPO PM produces a light-weight construction for the spacecraft
Reshetnev NPO PM developed and produced a light-weight construction of the “Express-AM44” payload module. On , it was sent to Thales Alenia Space (TAS) according to the work schedule confirmed by the customer.
It is not for the first time that NPO PM is building construction for the “Express-AM” payload modules. This time it’s a different construction design for the AM44 payload. The spacecraft “Express-AM44” is planned to launch in a cluster with “Express-MD1”, therefore the customer (the Russian Satellite Communication Company-RSCC) made new demands – to bring down the satellite mass.
According to Alexander Dostovalov, the “EXPRESS-AM” program manager in NPO PM, they had to make a new construction design despite the fact that they had already built a construction for the AM44 payload module.
Nevertheless this technical task was successfully carried out in the shortest time resulting a new light-built construction made of honeycomb panels that has become 20 kg less. The spacecraft mass was considerably reduced with using thinner skin for the honeycomb panels and changing the fluid passage profile.
Later the TAS experts will carry out integration works on the payload module equipment to further send it to Cannes and Toulouse for the testing. The works accomplished, the payload module would be sent back to NPO PM for the further integration and testing of the whole spacecraft.
The telecom satellite “Express-AM44” is being produced by NPO PM in cooperation with Thales Alenia Space under the State contract with Roskosmos, Ministry of Information Technologies and Russian Satellite Communication Company.
Reshetnev NPO PM is responsible for the satellite building on the whole including its operation systems’ module, payload module construction and L-band devices.
Thales Alenia Space supplies NPO PM with a payload module according to the contract with RSCC.
The “Express-AM” satellites are meant to replenish the national orbital constellation. The modern telecom satellites are characterized by a long lifetime, larger number of transponders and more intensive signal therefore simplifying the system’s ground segment.
