ECS/TMS/NBC Subsystem

BIA Number: 15711

Pricing Information

The Program anticipates a funding level of up to $60,000 for the contract award(s) resulting from this BIA.

Detailed Description of Effort and Tasks

The ECS/TMS/NBC is a common subsystem for all FCS manned ground vehicles. The ECS/TMS/NBC subsystem provides for a conditioned cabin environment, cabin pressurization, vetronics temperature control, utility and engine equipment temperature control, mobility system temperature control, vehicle ventilation, survivability system temperature control, mission system temperature control, air supply filtration, and the air supply life support system that conditions the air that directly supports the crew during NBC events. The subsystem shall interface with NBC sensor suite and the vehicle prognostic and health management subsystem.

All components will be based on an open system architecture and facilitate block upgrades spiral development throughout the life of the vehicle.

Initial subsystems requirements and architecture will be provided at the start of the contract.

Task 1
Define subsystem hardware/software design capable of meeting the performance and interface requirements provided by the LSI. Support refinement to the subsystem performance and interface requirements.

Task 2
Provide subsystem level functional schematics

Task 3
Provide 3D CAD Envelope Models and 2D layouts of Envelope Models/Layouts of the preferred subsystem arrangement for the major subsystem elements sufficient to define subsystem-to-vehicle interfaces and to show compliance with interface requirements. Provide 3D CAD envelope model datasets to be either PRO Engineer version 2001 or CATIA V4. If not available in either of these CAD formats, a STEP format file shall be submitted. 2D layouts to be contractor CAD dataset format and one 36" wide paper plot.

Task 4
Provide simulation model of subsystem performance to support vehicle performance simulation assessments. ·

  • EASY5 or MATLAB/Simulink for subsystem level analyses

Task 5
Provide ROM Subsystem-Level Reliability Assessment

Task 6
Provide preliminary repair/maintenance concepts associated with subsystem design.

Task 7
Provide description of the critical subsystem failure modes.

Task 8
Provide SDD Test and Evaluation roadmap for the subsystem elements necessary to validated simulation models and verify subsystem performance and RAM-D requirements.

Task 9
Provide subsystem attribute sensitivity (i.e., weight, volume, power, cooling) to potential growth in subsystem performance requirements as specified by the LSI.

Task 10
Provide a fabrication concept that addresses building and assembling the ECS/TMS/NBC subsystem components in sufficient detail to support manufacturing plan development.

Task 11
Offeror shall support SDD WBS development.
