    SECTION I

    MISSION AND OBJECTIVES

    I-i. PURPOSE.

    l-Z, This section describes the mission and objectives of boilerplate 13 (figurel-l). A mission profile is shown in figure 1-2.

    1-3. BOILERPLATE 13 MISSION.

    1-4. The Apollo-Saturn compatibility tests have the initial objectives of de-veloping and qualifying the spacecraft and systems to be used for manned earth-orbital flight. The unmanned boilerplate 13 configuration is the first of theselaunch vehicle and spacecraft compatibility tests. This test will also serve todemonstrate certain environmental and systems compatibilities. Boilerplatesare research and development vehicles which simulate production spacecraft insize, shape and structural soundness. Boilerplate 13 is equipped withinstrumentation to record mission parameter data for engineering review andevaluation. The data gained from testing of boilerplate configurations will beused in determining production spacecraft flight parameters.

    i-5. APOLLO FIRST ORDER TEST OBJECTIVES.

    1-6. The following are the primary test objectives of the boilerplate 13 flighttest:

    a. Demonstrate the physical compatibility of the launch vehicle and space-craft under preflight and flight conditions,

    b. Determine the launch and exit environmental parameters for verificationof design criteria.

    1-7. APOLLO SECOND ORDER TEST OBJECTIVES.

    1-8. The following are the secondary test objectives of the boilerplate 13 flighttest:

    a. Demonstrate the structural integrity of the launch escape system underflight loading conditions.

    b. Demonstrate satisfactory launch escape tower jettison.

    c. Demonstrate compatibility of the R&D communications and instrumentationsystems with launch vehicle systems.
