25、TC 5 “Space”, the secretariat of which is held by DIN. This standard (EN 16603-32-10:2014) originates from ECSS-E-ST-32-10C Rev.1. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2015, an

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. Th

27、is document has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following co

28、untries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

DIN EN 16603-32-10:2014-10 EN 16603-32-10:2014 (E) 5 1 Scope The purpose of this Standard is to define the Factors Of Safety (FOS), Design Factor and additional factors to be used for the dimens

30、ioning and design verification of spaceflight hardware including qualification and acceptance tests. This standard is not self standing and is used in conjunction with the ECSS-E-ST-32, ECSS-E-ST-32-02 and ECSS-E-ST-33-01 documents. Following assumptions are made in the document: that recognized met

31、hodologies are used for the determination of the limit loads, including their scatter, that are applied to the hardware and for the stress analyses; that the structural and mechanical system design is amenable to engineering analyses by current state-of-the-art methods and is conforming to standard

32、aerospace industry practices. Factors of safety are defined to cover chosen load level probability, assumed uncertainty in mechanical properties and manufacturing but not a lack of engineering effort. The choice of a factor of safety for a program is directly linked to the rationale retained for des

33、igning, dimensioning and testing within the program. Therefore, as the development logic and the associated reliability objectives are different for: unmanned scientific or commercial satellite, expendable launch vehicles, man-rated spacecraft, and any other unmanned space vehicle (e.g. transfer veh

34、icle, planetary probe) specific values are presented for each of them. Factors of safety for re-usable launch vehicles and man-rated commercial spacecraft are not addressed in this document. For all of these space products, factors of safety are defined hereafter in the document whatever the adopted

35、 qualification logic: proto-flight or prototype model. For pressurized hardware, factors of safety for all loads except internal pressure loads are defined in this standard. Concerning the internal pressure, the factors DIN EN 16603-32-10:2014-10 EN 16603-32-10:2014 (E) 6 of safety for pressurised h

36、ardware can be found in ECSS-E-ST-32-02. For loads combination refer to ECSS-E-ST-32-02. For mechanisms, specific factors of safety associated with yield and ultimate of metallic materials, cable rupture factors of safety, stops/shaft shoulders/recess yield factors of safety and limits for peak Hert

37、zian contact stress are specified in ECSS-E-ST-33-01. Alternate approach The factors of safety specified hereafter are applied using a deterministic approach i.e. as generally applied in the Space Industry to achieve the structures standard reliability objectives. Structural safety based on a probab

38、ilistic analysis could be an alternate approach but it has to be demonstrated this process achieves the reliability objective specified to the structure. The procedure is approved by the customer. This standard may be tailored for the specific characteristics and constraints of a space project in co

39、nformance with ECSS-S-ST-00.
