PROJECT DEVELOPMENT

Created by today:
ECS: 1500 new MBDs with 1900 new instances;
ICS: 475 new MBDs with 850 new instances;
CM, CRN: 198 new MBDs with 1300 new instances;
VP: 137 new MBDs with 800 new instances.

PROPOSALS

PVDF downers:
+ maintainability; easier to install and remove; flex hose and insulation elimination - reduced P/N quantity; installation and assembly procedures reduction; better separation with surrounding structure; weight saving; ducts cost saving.
- curved complex spud (if no flex hoses); temperature expansion and transfer additional loads to structure need to resolve; anchors is required.

Rotomolded downers:
+ straight simple spud; no issue with temperature expansion.
- cost; weight; hard to remove; may require partial removal of Vertical Panel assembly; more part numbers consuming.

Flex hoses

Original design

SEC. 46;
- All MoCo ducts are Kevlar but for the downer;
- New Design will be supported mostly by WEM brackets but for the section joint (SEC. 44-46);
- One MoCo duct uses OFCR as a support by means of back-to-back saddle installation;
- New silicone duct downer is now placed in SEC46.

riser to recirculation

Study in progress

(system removal required)

Disadvantages: Requires to remove central duct e.a. disconnect of all 4 downer packs; Requires to remove opposite RH sided downers and related system elements – LGV and CRN cable

Advantages: Less cost design. Total 2 supports per pack. No need to have additional 8 ducts, 8 sleeves, 8 brackets, 2 spanner bars, 6 close outs, 2 insulation details on LH side like on two-piece-downer design; No need to disconnect downers from 3rd support, no need to remove drip shield with electrical equipment

Removal: thru central area Design: downer – single piece downer, 1st end of pack – sleeve, 2nd end of pack – flex hose, supports per pack – 2

Systems to remove: LH OUTBD manifold, MOC duct (for access to sleeves between central duct and downers), Central Air duct, RH downers pack, LGV, CRN cable

Flex hoses

Downers

(one on each STA) for central assembly module to support different Systems and assemble them off the AP.

Redesign Vertical Panels to accommodate wire bundles, ECS ducts and risers to one common module.
