Deos includes an industry standard lightweight TCP/IP stack (LwIP) with a DAL-A sockets library so it can provide data transport during in flight or on ground as part of its standard package. While it may have high data integrity (e.g., through CRC or other such mechanisms), TCP/IP over Ethernet is a non-deterministic protocol. As such, it is not suitable for avionics applications that require determinism or high robustness. In contrast, there are several are several redundant and deterministic data network technologies such as ARINC-664/AFDX, time triggered ethernet (TTE), and time sensitive networking (TSN). These interfaces are based on switched Ethernet technologies and can include system redundancy such that they are applicable for aircraft data network applications. Their feature set enables them to be used as a digital backbone for aircraft control and other applications where both integrity and availability are essential. Each of these solutions generally requires specific end
Collins Aerospace recognizes the value the warfighter gets from reducing the Size, Weight and Power (SWAP) of the avionics systems. The war fighter also sees benefit from reuse of existing avionics and mission software modules, which frequently vary in software framework and thus are allocated to separate processors. A solution, as seen in the commercial IT industry would be the use of multi-core processing and hypervisors allowing the mixing of frameworks providing rapid integration with minimal SWAP. In avionics we must additionally provide assurance. This paper will explore our application of the FACE™ Technical Standard (Ref. [1]) to obtain framework variability, used in conjunction with a hypervisor to allow the resulting frameworks to exist in a single multi-core processing environment with safety assurance to the solution. The concept proposed was validated through demonstration of US Army and Collins software running on the same multi-core processor.
ABSTRACT The goals of sustainable manufacturing, as articulated by Organization for Economic Co-operation and Development (OECD), are to reduce the intensity of material use, energy consumption, emissions and unwanted by-products - while maintaining or improving the value of products to society and to organizations. Benefits that can be achieved through this practice include improved working conditions, public image, staff morale, customer loyalty, brand value, profits, sales turnover, product performance, reduction in waste generation and staying ahead of regulatory concerns. Achieving such goals begins early in the product design phase with consideration toward materials used and processes invoked in manufacturing. Ultimately, a full sustainability assessment must include the product's End-of-life (EOL) impact, factoring environmental impacts of landfill and recycling emissions. This paper focuses on using an End-Of-Life impact assessment for a set of materials and processes commonly
ABSTRACT The current avionics integration approach is becoming unaffordable partly due to the schedule and cost associated with integrating an avionics system into each configuration of each platform using its native interface. The United States (U.S.) Army's Aviation and Missile Research, Development, and Engineering Center (AMRDEC) Director for Aviation Development tasked the Modular Integrated Survivability (MIS) team to work with the U.S. Army Aviation Engineering Directorate (AED), the Army's airworthiness authority, to explore innovative integration approaches to streamline the integration process while still satisfying airworthiness certification requirements. AED has been engaged since the inception of the MIS Science and Technology (S&T) program. The MIS team, along with AED, has focused on developing the concept of using capability interfaces to communicate with similar avionics systems. The capability interfaces are built by abstracting the native interfaces allowing for a
SW DONKI is a comprehensive Web application for space weather forecasters, scientists, and the general space weather community. It serves as an archive for space weather activities including solar flares, coronal mass ejections (CMEs), solar energetic particles, and geomagnetic storms. An innovative feature of the system is the ability to generate, modify, and store complex linkages between space weather events — creating a comprehensive network of relationships between activities, and identifying potential cause-and-effect paradigms for each space weather event. SW DONKI also provides public access to all human-generated event analysis and notifications produced by the Space Weather Research Center (SWRC) forecasting team at CCMC (Community Coordinated Modeling Center).
