FALCON USER’S GUIDE ENVIRONMENTAL COMPATIBILITY VERIFICATION Prior to launch, SpaceX requires that customers verify the compatibility of their systems with the Falcon vehicles’ maximum expected flight environments. SpaceX initiates this process by providing the applicable environments. The customer then summarizes its approach to environmental compatibility verification, and the process concludes with the customer providing test data to SpaceX, if necessary (Table 7-2). Table 4-16 summarizes the typical verification activities performed by the customer and provides test levels based largely on Section 4.3 of this guide. Mission-unique limit levels and coupled loads analysis levels will be developed during the mission integration process and will serve as the basis for the verification activities. Alternate verification approaches may be acceptable, but coordination with SpaceX is required. Table 4-16: Spacecraft environmental compatibility verification example Environment Verification Activities and Test Levels Quasi-Static Loads Qualification: Limit levels x 1.25 (Section 4.3.1) Protoqualification: Limit levels x 1.25 Acceptance: Limit levels x 1.0 Sine Vibration Qualification: Limit levels x 1.25, two octave/minute sweep rate (Section 4.3.2) Protoqualification: Limit levels x 1.25, two octave/minute sweep rate Acceptance: Limit levels x 1.0, four octave/minute sweep rate Acoustic, Shock, and Customers shall provide details and justification showing compatibility of spacecraft Random Vibration hardware to acoustic, shock, and random vibration environments presented herein. SpaceX (Section 4.3.3 – does not have specific requirements on spacecraft test margins; however, SpaceX generally 4.3.5) recommends the following standards as references when developing spacecraft/component test campaigns: GEVS (GSFC-STD-7000), SMC-S-016, or NASA-STD-7001A. Test campaigns that do not align with methodologies presented in the above standards should have sufficient accompanying justification. SpaceX can aid in evaluation of these environments if requested Electromagnetic SpaceX standard service includes an electromagnetic compatibility assessment. (Section 4.3.6) SpaceX recommends electromagnetic interference/compatibility testing be conducted for RF-sensitive payloads and may request insight into relevant testing performed Pressure SpaceX recommends venting analyses be conducted and may request insight into relevant (Section 4.3.7) analyses performed Thermal SpaceX recommends thermal cycle and thermal vacuum testing be conducted and may (Section 4.3.8) request insight into relevant testing performed © Space Exploration Technologies Corp.
