1. MC Type-B fit up review1 Review of MC Type B assembly clearances reviewing A-to-B and B-to-C interfaces 3/1/07 Summary: Wing interfaces look okay between A/B and B/C. There is clamp interferences between A/B (see slide 3) and between B/C (see slide 11 and 12).

2. 2 Type-A Top Bottom Type-B A side Type-B B side Top Bottom Type-B to Type-A interface

3. 3 Type A Section Cut Looking Inboard Top Type B 0.162” clearance These clamps have an interference Hole # 59 Hole # 61 Type-AType-B Clamps on A and B where there is interference or close contact is indicated. Clamp measured needed. Hole # 58 Hole # 60 A-to-B Fit-up See next slide for winding form interface.

4. 4 0.374” Type A Top Type B This will be a tight region. Metrology data of the winding form and winding in this area would be useful.

5. 5 MC Type-A to Type-B large wing interface clearance is 0.378” at the edge in the CAD model. Type-B wing Type-A wing pocket Type-B A side

6. 6 MC Type-A to Type-B large wing pocket interface clearance is 0.358” in the CAD model. Underside surface of Type-A shown in yellow.

7. 7 MC Type-A to Type-B small wing pocket interface clearance is 0.445” in the CAD model. Type-B, Side A Type-A pocket surface

8. 8 Type-B Top Bottom Type-C Cut-Away View Type-B to Type-C interface

9. 9 Outside Wing Flange B Side MC Type-C to Type-B interface clearance at wing flange B side edge is 0.272” in the CAD model located at the edge of the wing. Interfacing Type-C surface Only the edge indicated in the circle area needs to be measured. See next slide for further details.

10. 10 MC Type-B to Type-C large wing interface surface clearance is 0.628” in the CAD model. There area should be ample space for the interfacing surface.

11. 11 Type-C Type-B 0.247” shell clearance along this local region. Rotated expanded view of area indicated. This will be a tight region. It appears that the winding itself will fit okay (see next slide) although there is clamp problems

12. 12 Ignoring the clamps their appears to be no winding interferences. Type-C Clamp 61 and clamp hardware interferes with the Type-B winding and local cable. Hole 61…I think! Hole # 63 Hole # 65

13. 13 MC Type-C to Type-B large wing pocket minimum interface clearance is 0.249” in the CAD model.

14. 14 Measurements using the Leica laser tracker desired for flange surfaces.

15. 15 0.50” clearance over most of this length. Type-B Side A Measurement needed along this local edge of the Type-B winding form.

16. 16 Type A Type B Measurement needed at the top of the Type-B in this region at the top of the MC. 0.72”
