  1. EIP & NASDAT Status 1/14/2011

  2. Status • EIP Pre-Production (2 units) • Enclosure design complete • All major materials procurements issued • Subassemblies: • Ethernet Switch: Fabrication • DCMON: Subcontractor PCB layout • SSPC: Fabrication • AC Distribution: Assembly • Box-level Assembly Drawing: 25%

  3. Status • NASDAT Pre-Production (1 unit) • All major materials procurements issued (includes enclosures) • Exception: Internal IMU not purchased • Subassembly Status: • Analog Isolation Card: Design Complete, prototype tested • Interface Isolation Card: PCB Layout • Power Distribution Card: Requirements Definition • Note: Box assembly will be in-house

  4. Status • AC Distribution PCB:

  5. Status • SSPC Completed PCB Layout:

  6. Status • DCMON PCB Parts Placement:

  7. Status • Ethernet Switch Connector Board PCB: • Ethernet Switch Main PCB (Sixnet):

  8. Status • NASDAT Interface Isolation Card:

  9. Status • Changes Since PDR (EIP): • EIP cable ID • Each EIP gets unique ID (simplifies network) • (4) EIP Ethernet Connectors (was 2) • 8 10/100 ports, 4 1G ports (unchanged) • Finalized connector locations • All inputs on left, all outputs & data on front • GPS feed on right (GH only) • WoW / Gear / Cockpit Switch #1 • Using Polyfuses for cockpit switch #1

  10. Electrical • New EIP harness connectors are available from ASF for aircraft use: • D38999/26WC98PN (Interlock): 150pc • D38999/26WG16PN (AC/DC): 250pc • TV06RQW-21-75S (Ethernet): 100pc • CA-628485-134 (RJ45->quadrax): 10pc

  11. Ethernet • EIP Box Connector: See Pinouts • (2) 100Mbit x 4 & (2) 1Gbit x 2 • Mates to TVP06RQW21-75S ($800/ea) • Bulkhead Connector: • Amphenol 10-646787-75S ($1.7k/ea, $1.2k @ 12pc) • Pin / Socket, 21-75 shell style • Leak Rate: 1*10-3 cm3/s (~0.3 ft3/mission) • Mates to TVP06RQW21-75S & TVP06RQW21-75P ($600/ea) • Cable: Tensolite NF24Q100 ($4/ft) • Cost Estimate: $15k/ER2, $4k/WB57 • These items have not been purchased

  12. Mechanical • Enclosure Drawing: a9444-ASF11-341 • Expect sheet metal in house ~2/14/11 • Dimensions are same as legacy ER-2 EIP • 10.6” W x 6.72” L x 4.32” H • 38% volume reduction over GH package by consolidating EIP & ethernet switch

  13. Mechanical PDR (9/14/10) Pre-Production (12/21/10)

  14. Mechanical FRONT LEFT RIGHT Note: cross-hairs & leaders due to images pasted from EIP sheet metal drawing

  15. Schedule / Milestones • EIP Milestones: • Aircraft Fit Check: 2/4/11 • Start of Pre-Production: 3/23/11 • CDR: 4/15/11 • Start of Production: 5/11/11 • Production Complete: 7/11/11 • Risks / Issues: • ARRA funding cuts off 7/29/11 • Integration of hardware with aircraft – dates?

  16. Schedule / Milestones • NASDAT Milestones: • Start of Pre-Production: 4/11/11 • CDR: 4/15/11 • Start of Production: 5/31/11 • Production Complete: 3/2012 • Risks / Issues: • NASDAT assembly schedule tied to deployment staffing
