EXOMARS 2016 MISSION: AN OVERVIEW OF THE PHASE C ACTIVITIES PROGRESS

摘要

The ExoMars Programme features two missions, one to be launched in January 2016 and one in April/May 2018. Hence for the 2016 mission ESA is procuring a large Spacecraft Composite consisting of a Trace Gas Orbiter (TGO) and an EDL Demonstrator Module (EDM). The Spacecraft Composite will be launched from Baikonur in January 2016 by a Proton Launcher, to arrive at Mars in mid-October of 2016. The 2016 mission industrial activities are now focused on the Phase C with the System-CDR planned to be completed by the end of the current year 2013. The EDM development is on schedule; in particular the EDM SM has been subjected to leak-tests in TAS-I to prove the tightness of the aeroshell. Sine and static have followed to demonstrate capability to withstand the launch and entry mechanical loads. The EDM functional qualification campaign has also started with software integration on the EDM Avionic Test Bench (ATB). The Wind Tunnel Test campaign has been completed and the Aero-Thermodynamic Data Base is now consolidated. The High Altitude Drop Test, to verify the parachute performances in a high altitude environment, is planned for completion by the end of 2013. At subsystem level the development tests of the Crushable Structure of the Landing Platform have been completed and the structure is ready for the final qualification tests planned in October this year. The TGO Mechanical Thermal & Propulsion (MTP) and Avionics Electronic and Radiofrequency (AER) PDR's were completed in the course of the year 2012. The phase C analyses campaign has started with the Guidance Navigation and Control (GNC) Robustness Analyses. The Central Software (CSW) and Satellite Database (SDB) development is being worked out in staggers (from V0 to V4) and the delivery of the first version for the start of AIT of the TGO ATB is planned at end of November this year. The 2.2 meter High Gain Antenna has entered the detailed analyses phase and its CDR is planned in Sept 2013. The TGO Harness Manufacturing Review has been held in Jan 2013 and the Delivery Review Boards (DRBs) of the three batches are scheduled in October and December of 2013 and March 2014, respectively. At MTP level the final structural, thermal and thermo-elastic analyses have been completed, testing activities on Central Tube (CT) Structural Model (SM) and Propulsion Engineering Verification Model (PEVM) were successfully closed in June and May 2013, while Thermal Engineering Verification Model (TEVM) ones are planned to be done in October 2013. The MTP CDR is now scheduled at the end of October 2013.
