    A1. Details of Mounting Position

    Distances from STA* to the separation plane are as follows:

    ・For single launch STA 6698.5 mm

    ・For multi launch STA 5238.5 mm

    *STA (station): The origin is at the top of the fairing, from which distances are measured in a

    longitudinal direction of LV, or along XB axis. The figure increases toward lower stages.

    The coordinate system in this document is the same as shown in Chapter 2.2. The origin is at the

    center of the separation plane.

    A2. PL Usable Volume

    PL usable volume is defined in Chapter 4.1.1.

    The usable volume for PL in single launch is shown in Figure 4-1.

    The usable volume for Small satellite in multi launch is shown in Figure A2-1.

    The load applied to PL’s rear flame by a separation spring during PL/LV mating dose not exceed 1,400

    N.

    PL’s rear frame shall satisfy the following requirements.

    PL’s rear frame and PAF’s separation flange are joined by a Marman clamp band. Its typical

    specifications are as follows:

    Tension : 18 [kN] or less

    (temporarily rises up to 35 kN during clamping work.)

    (6) Separation Switch (Micro Switch)

    Separation switches, which detect PL/LV separation status, are installed on LV side (PAF). More

    switches can be mounted on PL side (PL rear frame) if needed. The standard number of the switches is 2

    for each side.

    The standard specifications of the separation switch are shown in Table A3-4.

    The position of PL separation switch (if needed) and its contact surface on LV side are shown in Figure

    A3-7.

    The position of LV separation switch and its contact surface on PL side are shown in Figure A3-8.

    (7) Separation Spring

    Table A3-5 shows the number of separation springs. The number will be decided by LSP according to

    the mass of PL and the separation speed that varies for the LV configuration. The locations of separation

    springs are shown in Figure A3-2.

    If Customer requires any change in the number and location, contact your Program Director.
