Functional Description
The Parvus®DuraCOR®311 is an ultra-small form factor (SFF) tactical mission computer based on a low-
power, four-core Intel®Atom™ 3845 (Bay Trail-I) processor equipped with a rugged Flash disk and PCIe-
Mini Card I/O expansion slots. At less than 40 cu. in. in volume, 1.5 lbs. in weight, and 15W power, this
miniature multi-core rugged Commercial Off-the-Shelf (COTS) processor is an ideal x86 computing
solution for size, weight, power and cost (SWaP-C) sensitive mobile, airborne, ground, manned and
unmanned vehicle and sensor applications. Optimized for high performance energy efficient processing,
the unit boasts a quad-core 64-bit Intel Architecture (IA) CPU with integrated Intel HD Graphics.
The ultra-reliable and modular design of the DuraCOR 311 features high mechanical robustness and I/O
flexibility to meet the needs of civil and military aerospace platforms. The unit features an industrial-grade
Intel-based Computer-on-Module (COM) tightly integrated with a Flash SSD and system carrier board,
which provides a full complement of standard vetronics I/O interfaces (including USB, Ethernet, Serial,
DIO, Video, Audio), as well as up to three slots for optional add-on Mini-PCIe I/O modules. In addition to
internal mSATA and microSD card slots, the system offers an optional removable 2.5” SATA SSD storage
option for high capacity storage and information assurance requirements. Like other DuraCOR models,
the 311 leverages both an ecosystem of rugged COTS Mini- PCIe modules (including MIL-STD-1553 and
ARINC429 avionics databus interfaces) and Curtiss-Wright’s responsive, cost-competitive application
engineering services to deliver Modified COTS (MCOTS) variants quickly and without a traditional NRE
fee.
The unique combination of small size, low-power multi-core processing, and flexible I/O of the DuraCOR
311 delivers new capabilities for Command, Control, Communications, Computers, Intelligence,
Surveillance and Reconnaissance (C4ISR) applications. This compact system supports a wide operating
temperature range of -40 to +71°C (-40 to +160ºF) without fans or active cooling requirements. It thrives
in extreme shock and vibration conditions, high altitude, and humidity, making it well suited for mobile,
tactical, aerospace, and ground vehicle applications. Reliably designed for use onboard aircraft and
vehicle platforms, the DuraCOR 311 has successfully passed comprehensive qualification testing to MIL-
STD-810G, MIL-STD-461F, MIL-STD-1275D, MIL-STD-704F and RTCA/DO-160G test conditions for
environmental, power and EMI (thermal, shock, vibration, dust, water, humidity, altitude, power
spikes/surges, conducted/radiated emissions and susceptibility).
Housed in a rugged sealed IP67-rated (dust and water proof) aluminum chassis with MIL-performance
circular connectors, the DuraCOR 311 features advanced EMI filtering and power conditioning to protect
against input vehicle/aircraft voltage surges, spikes and transients. In addition, optional 50ms power hold-
up capabilities are supported for MIL-STD-704F aircraft power switch-over requirements.
