Preparation Instructions

1Reference documentsThe applicable issue of the documents cited herein, including their approval dates and dates of any applicable amendments, notices, and revisions, shall be as specified in the contract.

2FormatThe Store Separation Methodology Plan shall be in the contractor's format.

3ContentThe Store Separation Methodology Plan shall contain the following:

3.1Freestream DatabaseThis section shall describe the development of a freestream database to include the method of data collection, data ranges, data smoothing, and the use of tie-in runs.

3.2Aircraft Proximity (Grid) DatabaseThis section shall describe the development of an aircraft proximity (grid) database to include the method of data collection, database build-up procedure, symmetry assumptions, methods used, and sample comparison plots.

3.3Six-Degree-Of-Freedom (6DOF) Model

3.3.16DOF Model DevelopmentThis section shall describe the development of the 6DOF model to include use of data inputs, such as freestream database, grid database, ejector modeling, and mass property information, to create the integrated trajectory modeling capability.

3.3.26DOF Predictions to CTS TrajectoriesThis section shall describe the generation of trajectories to include database comparison, verification of critical 6DOF input data, validation of database assumptions, adjustments made to the grid database, and sample comparison plots.

3.4Flight Envelope AnalysisThis section shall describe the analysis of the flight envelope to include the range of flight conditions, store configurations, aircraft configurations, assumptions and interpolation methods, and sample flight condition plots.

3.5Miss Distance Analysis and PredictionsThis section shall describe the analysis of miss distances in the flight envelope to include the method of calculation and assumptions, sample miss distance plots, and the definition of critical minimum miss distance criteria.

3.6Recommendation of Flight Test PointsThis section shall describe the recommendations of flight test points to include the method of comparison for flight conditions and criteria for test point selection.

3.7Recommendation of Safe and Acceptable Separation EnvelopeThis section shall describe the generation of the clearance envelope to include the definition of safe and acceptable separation criteria, use of miss distance conclusions, method of envelope generation, and sample clearance envelope plots.
