Space engineering - Electrical design and interface requirements for power supply

Space engineering - Electrical design and interface requirements for power supply

The target applications covered by this standard are all missions traditionally provided with power distribution and protection by LCLs/RLCLs (science, earth observation, navigation) with exclusion of telecom applications which are traditionally provided with power distribution and protection by fuses.
The present standard applies to power distribution by LCLs/RLCLs for power systems, and in general for satellites, required to be Single Point Failure Free.
The present standard document applies exclusively to the main bus power distribution by LCLs/RLCLs to external satellite loads.
Internal power system protections of LCLs/RLCLs are not covered.
Paralleling of LCLs to increase power supply line reliability is not covered by the present standard, since this choice does not appreciably change the reliability of the overall function (i.e. LCL plus load).
In fact, a typical reliability figure of the LCL (limited to the loss of its switch ON capability) is 20 FIT or less.
If the load to be connected to the LCL line has a substantial higher failure rate than this, it is not necessary to duplicate the LCL to supply that load.

Ingénierie spatiale - Exigences de conception et d'interface électriques pour alimentation bord

Vesoljska tehnika - Električna zasnova in zahteve vmesnika za napajalna omrežja

Vse ciljne aplikacije, zajete v tem standardu, so misije, ki so običajno zagotovljene z distribucijo električne energije in zaščito z omejevalniki LCL/RLCL (znanost, zemeljska opazovanja, navigacija), razen telekomunikacijskih aplikacij, ki so običajno zagotovljene z distribucijo električne energije in zaščito z varovalkami.
Ta standard se uporablja za distribucijo električne energije z omejevalniki LCL/RLCL za napajalne sisteme in na splošno za satelite, ki morajo biti brez enotočkovnih napak.
Ta dokument se uporablja izključno za distribucijo električne energije prek glavnega vodila z omejevalniki LCL/RLCL za zunanja bremena satelita.
Notranja zaščita napajalnih sistemov omejevalnikov LCL/RLCL ni zajeta.
Vzporedna vezava omejevalnikov LCL za povečanje zanesljivosti oskrbe z električno energijo ni zajeta v tem standardu, saj ta izbira ne spremeni znatno zanesljivosti celotne funkcionalnosti (tj. omejevalnika LCL z bremenom).
Običajna vrednost zanesljivosti omejevalnika LCL (omejena na izgubo zmogljivosti vklopa stikala) je 20 FIT ali manj.
Če ima breme za povezavo z linijo omejevalnika LCL znatno višjo stopnjo napake v primerjavi z omenjeno, podvojevanje omejevalnika LCL za napajanje tega bremena ni potrebno.

The present standard document applies exclusively to the main bus power distribution by LCLs/RLCLs to external satellite loads. A particular case of LCLs (Heater LCLs, or HLCLs) is also treated. The HLCLs are the protections elements of the power distribution to the thermal heaters in a spacecraft. Internal power system protections of LCLs/RLCLs are not covered. Paralleling of LCLs to increase power supply line reliability is not covered by the present standard, since this choice does not appreciably change the reliability of the overall function (i.e. LCL plus load). In fact, a typical reliability figure of the LCL (limited to the loss of its switch-on capability) is 20 FIT or less.

EN 16602-60:2023

The Scope of the Standard remains unchanged.
This standard defines the requirements for selection, control, procurement and usage of EEE components for space projects.
This standard differentiates between three classes of components through three different sets of standardization requirements (clauses) to be met.
The three classes provide for three levels of trade-off between assurance and risk. The highest assurance and lowest risk is provided by class 1 and the lowest assurance and highest risk by class 3. Procurement costs are typically highest for class 1 and lowest for class 3. Mitigation and other engineering measures may decrease the total cost of ownership differences between the three classes. The project objectives, definition and constraints determine which class or classes of components are appropriate to be utilised within the system and subsystems.
a.   Class 1 components are described in Clause 4.
b.   Class 2 components are described in Clause 5
c.   Class 3 components are described in Clause 6.
The requirements of this document apply to all parties involved at all levels in the integration of EEE components into space segment hardware and launchers.

Space product assurance - Processing and quality assurance requirements for hard brazing of metallic materials for flight hardware
EN 16602-70-40:2023

This Standard specifies the processing and quality assurance requirements for
brazing processes for space flight applications. Brazing is understood as the
joining and sealing of materials by means of a solidification of a liquid filler
metal.
The term brazing in this standard is used as equivalent to soldering, in cases that
the filler materials have liquidus temperatures below 450 °C.
Brazing and soldering are allied processes to welding and this standard is
supplementing the standard for welding ECSS-Q-ST-70-39.
This standard does not cover requirements for:
• Joining processes by adhesive bonding (ECSS-Q-ST-70-16),
• Soldering for electronic assembly purposes (ECSS-Q-ST-70-61),
• Soldering used in hybrid manufacturing (ESCC 2566000).
The standard covers but is not limited to the following brazing processes:
• Torch brazing,
• Furnace brazing,
• Dip Brazing and Salt-bath brazing,
• Induction Brazing.
This Standard does not detail the brazing definition phase and brazing pre-
verification phase, including the derivation of design allowables.
This standard may be tailored for the specific characteristic and constraints of a
space project in conformance with ECSS-S-ST-00.

This standard addresses the requirements for performing verification by testing of space segment elements and space segment equipment on ground prior to launch. The document is applicable for tests performed on qualification models, flight models (tested at acceptance level) and protoflight models.
The standard provides:
• Requirements for test programme and test management,
• Requirements for retesting,
• Requirements for redundancy testing,
• Requirements for environmental tests,
• General requirements for functional and performance tests,
NOTE Specific requirements for functional and performance tests are not part of this standard since they are defined in the specific project documentation.
• Requirements for qualification, acceptance, and protoflight testing including qualification, acceptance, and protofight models’ test margins and duration,
• Requirements for test factors, test condition, test tolerances, and test accuracies,
• General requirements for development tests pertinent to the start of the qualification test programme,
NOTE Development tests are specific and are addressed in various engineering discipline standards.
• Content of the necessary documentation for testing activities (e.g. DRD).
Due to the specific aspects of the follow ing types of test, this Standard does not address:
• Space system testing (i.e. testing above space segment element), in particular the system validation test,
• In-orbit testing,
• Testing of space segment subsystems,
NOTE Tests of space segment subsystems are often limited to functional tests that, in some case, are run on dedicated models. If relevant, qualification tests for space segment subsystems are assumed to be covered in the relevant discipline standards.
Testing of hardware below space segment equipment levels (including assembly, parts, and components),
• Testing of stand-alone software,
NOTE For verification of flight or ground softw are, EN 16603-40 (ECSS-E-ST-40) and EN 16602-80 (ECSS-Q-ST-80) apply.
• Qualification testing of tw o-phase heat transport equipment,
NOTE For qualification testing of tw o-phase heat transport equipment, EN 16603-31-02 (ECSS-E-ST-31-02) applies.
• Tests of launcher segment, subsystem and equipment, and launch facilities,
• Tests of facilities and ground support equipment,
• Tests of ground segment.
This activity will be the update of EN16603-10-03:2014
