Compatible with OpenVPX/SOSA slot profile SLT3-PER-1U-14.3.3, Payload Modules connect directly to a dedicated 1 x1 PCIe GEN2 port to manage, monitor and control all RS-232/422/485 and ARINC 429/575 data using NAI’s multifunction I/O board Software Support Kit library package, while a 2nd dedicated 1 x1 PCIe GEN2 port handles all aspects of TTE, AFDX/A664p7 or Best Effort Ethernet utilizing TTTech’s full suite of configuration software.

In addition, NAI’s Configurable Open System Architecture™ (COSA®) allows for the reconfiguration of any board function module to support specific customer requirements with over 73 I/O, communications, measurement or simulation modules available. For example, the SC3 module can be replaced with a module that offers four redundant MIL-STD-1553 channels (FTC). NAI’s commitment of a safety critical DO-178 and DO-254 certification support path leverages the COSA modular architecture for the basis, growth and sustainment of certifiable systems.

“Certifiable solutions demand multiple deterministic communications interfaces. Customers demand modularity, configurability, adaptability and flexibility.” states Lino Massafra, VP of Sales and Marketing. “The 68G5P offers the best of all feature sets.”

Ideally suited for rugged military and aerospace applications, the VPX68 provides up to 400 Watts of power (VITA 47 CC4 temperature range, full load) with six outputs and is compliant with MIL-STD-704A-F & MIL-STD-1275E.

Other features include integrated holdup time, remote error sensing and a built-in EMI filter compliant with MIL-STD-461F — all within a single slot 1.0″ pitch, 3U package. The VPX68 is designed to meet standard 3U VPX mechanical requirements and has VITA 62 compatible keying, outputs & signaling, user programmability, I2C communication, geographical addressing, IPMI-Dual PMBus, programmable over-temperature monitor, programmable voltage and current settings which optimize the power distribution between outputs and a five-state status LED.

“The VPX68 fulfills a unique requirement expressed by our customers by providing an input which accepts +28VDC (+16 to +60 VDC continuous) and provides 50 milliseconds of holdup time at 400 Watts within a VITA 62 compatible product while meeting stringent power requirements in a compact rugged COTS package,” states Lino Massafra, VP of Sales and Marketing. “Many of today’s military systems rely heavily on high efficiency power supplies that can support OpenVPX requirements and withstand MIL-STD-704 as well as MIL-STD-1275E low and high voltage transients. The VPX68 is the latest in a complete line of NAI VPX power converters that support some of today’s most demanding system power requirements.”

“The COTS SIU36 integrates NAI’s Configurable Open System Architecture (COSA™) that maximizes modularity, flexibility, adaptability and I/O density while minimizing SWaP-C with no NRE,” states Lino Massafra, VP of Sales and Marketing. “The SIU36 is ideally suited to meet the demanding requirements of the DCU for Bell’s 360 Invictus to bring a holistic view of the aircraft systems to collect and analyze vehicle data to optimize maintenance and servicing to reduce sustainment costs.”

The DCU supports hundreds of digital and analog I/O, including programmable Discrete, A/D, D/A, Strain Gauge, Thermocouple, RTD, Variable Reluctance/Monopole, Chip-detect and LVDT with AC Reference measurement signals along with several communications interfaces including MIL-STD-1553, RS-422, ARINC-429 and Ethernet. The DCU manages, monitors and controls signals to and from the Vehicle Management System (VMS) and Heath Usage Monitoring System (HUMS).

The Bell 360 Invictus relies on proven systems and innovative processes to mitigate technical risk and improve lethality at an affordable cost for the FARA program competition that is part of the US Army’s Future Vertical Lift (FVL) program. The Bell 360 Invictus was one of two prototypes selected by the U.S. Army to complete a detailed design, build and test for a government flight test in 2023.
