Statement of Work (SOW)

NASA/Goddard Space Flight Center (GSFC) aims to leverage existing design and analysis work to design and analyze the mechanical structural interfaces for microwave instruments intended for airborne science missions on the NASA Boeing 777 aircraft. The instruments include the Microwave Barometric Radar and Sounder (MBARS), the Configurable Scanning Submillimeter-wave Instrument/Radiometer (CoSSIR), and the Conical Scanning Millimeter-wave Imaging Radiometer (CoSMIR). These instruments will be mounted on the Community Interface Plate in the Boeing 777 cargo hold, and the mechanical interface must accommodate required ultimate load factors and differential pressure.

This SOW outlines five key deliverables:

1. MBARS GOLA Antenna Mechanical Analysis: Update a Pre-3 version of the analysis to include a margin of safety table based on NASA Boeing 777 cargo bay limits and Finite Element Analysis (FEA) model validation. This includes two reviews with the NASA Boeing 777 engineering team and one post-review revision.
2. MBARS GOLA Antenna Hermetic Bulkhead Enclosure Design: Design an enclosure to hold the GOLA antenna at two degrees off-Nadir, to be located on the Community Instrument Plate. This design must interface mechanically with the plate and be non-interfering with aircraft structure.
3. MBARS GOLA Antenna Hermetic Bulkhead Enclosure Mechanical Analysis: Perform mechanical analysis of the enclosure designed in Deliverable 2, following the format and requirements of Deliverable 1. This includes two reviews and one post-review revision.
4. CoSMIR/CoSSIR Hermetic Bulkhead Interface Ring Design: Design a single ring to interface the CoSMIR or CoSSIR radiometer to the 16-inch ports on the NASA B777 community interface plate. The bottom interface of this ring will be replaceable for adaptation to different aircraft bulkheads.
5. CoSMIR/COSSIR Interface Ring Mechanical Analysis: Conduct mechanical analysis of the interface ring designed in Deliverable 4, including two 1-hour reviews and one post-review revision.

The work is to be performed from task award through 10 weeks After Receipt of Order (ARO).

All design efforts require communication with NASA engineering teams as needed, and include single reviews with the NASA Boeing 777 engineering team and post-review revisions. The designs must accommodate NASA Boeing 777 draft requirements as detailed in the "NASA's Boeing 777 Design Requirements Document 7-000-STDR-801 Draft".
