All rights reserved. No US. Export Controlled Data. 12 3.3.5 SHOCK Purpose: To ensure Payloads are compatible with shock environments experienced during flight. The shock response spectrum MPE, for Q, at the Payload mechanical interface for fairing deployment and Co- Payload separations, as well as the maximum allowable shock fora single separation system are defined in Table 3-6 and Figure 3-4. These levels are defined assuming a minimum of 3 bolted joints between Co-Payloads. Customers flying mission-unique configurations are encouraged to independently evaluate the shock levels produced by their Payload’s separation system. Customer is responsible for verifying compliance to both this requirement and the shock levels for the Payload separation system. To ensure Mission safety for Co-Payloads, separation systems provided by the Customer must be approved by SpaceX (reference Section 3.4.1.3). Additional constraints maybe imposed if the separation system exceeds shock levels listed in Table 3-6. A Mission-specific analysis will not be provided by SpaceX. Verification Testing is ADVISED to the shock test levels and durations defined in Table 3-15 in accordance with the MPE defined in this section. Download 2.78 Mb. Share with your friends:
