Use & Relationship

The Repeated Loads Design Criteria Report describes the spectrum of loads the aircraft store will encounter across its operational service life. The data will be used in the calculation of the store's fatigue life in order to verify the store has met the system performance requirements in the specified operational environment.

This Data Item Description (DID) contains the format, content, and intended use information for the data product resulting from the work task described by the contract SOW.

This DID supersedes DI-SESS-82232.
