Abstract: A multi-purpose application chassis may provide multiple mission services and includes a chassis housing having a front-mounted display interface, one or more rear-mounted input/output (I/O) connectors, a first front-mounted slot configured for a removable encryptor module, and a second front-mounted slot configured for a removable baseboard module. The removable baseboard module includes a first programmable logic to provide zero root of trust, second programmable logic for I/O and network processing, a chip scale atomic clock (CSAC) configured as a master time source, a plurality of storage drives for network attached storage (NAS), and a plurality of transceivers to provide I/O between the I/O connectors and the first and second programmable logic. The first slot and storage drives are configured to handle COTS SATA encryption modules as well as PCIe encryption modules, and when installed can provide Data-at Rest (DAR) NAS.

Abstract: A convection cooled chassis providing conduction cooling to components within includes a backplane card that interfaces with an interconnect assembly, and one or more VPX backplane cards, each with a plurality of component interfaces and a backplane card interface to engage the backplane card. Static elements that are not subject to redesign are disposed on the backplane card, so they do not need to be reorganized when contacts, pins, and component interfaces are altered. Different VPX backplane cards are swappable with the backplane card. The component interfaces and backplane card interface are disposed on opposing sides of the VPX backplane card.

Abstract: The modular avionics system may include one or more centralized processing line-replaceable units (LRUs), the centralized processing LRUs including at least one multi-core computer processor, one or more multi-function display (MFD) units configured to receive imagery data from the centralized processing LRUs and display the imagery data on a display device, one or more control display units (CDUs) configured to receive imagery data from the centralized processing LRUs and display the imagery data on a display device, the MFD units and the CDUs including one or more user input devices, the MFD units and the CDUs including at least one logic module, the CDUs and the MFD units configured to transmit user input data from the user input devices to the centralized processing LRUs, the centralized processing LRUs constructed from a plurality of component slices, wherein a first component slice and at least a second component slice are reversibly couplable.
