EVOLUTION OF 360 DEGREE LOCAL SITUATIONAL AWARENESS (LSA) TO AID THE WARFIGHTER

2024-01-3451

11/15/2024

ABSTRACT Northrop Grumman has developed a software and hardware solution to provide enhanced 360 degree local situational awareness (LSA) to enable the warfighter with an overmatch capability on today’s modern battlefield. The architecture exploits technological gains in cameras, video processing, and video compression. The approach allows rapid comprehension of local and remote situational views presented with operational relevance for a ground combat platform or tactical wheeled platform crew. The 360 Degree LSA approach provides direct visualization of relative positioning of targets, threats, and lines of fire; and additionally offers common situational understanding / operational picture from the dismounted soldier to higher echelon commands. The approach provides prioritized information through LSA software to provide an enhanced view to the warfighter whereas the squad leader becomes an integral part of the crew with a view of the common operating picture (mounted) and

The Operation Phase as the Currently Underestimated Phase of the (Safety and Legal) Product Lifecycle of Autonomous Vehicles for SAE L3/L4 – Lessons Learned from Existing European Operations and Development of a Deployment and Surveillance Blueprint

2023-01-1906

12/29/2023

Advanced Autonomous Vehicles (AV) for SAE Level 3 and Level 4 functions will lead to a new understanding of the operation phase in the overall product lifecycle. Regulations such as the EU Implementing Act and the German L4 Act (AFGBV) request a continuous field surveillance, the handling of critical E/E faults and software updates during operation. This is required to enhance the Operational Design Domain (ODD) during operation, offering Functions on Demand (FoD), by increasing software features within these autonomous vehicle systems over the entire digital product lifecycle, and to avoid and reduce downtime by a malfunction of the Autonomous Driving (AD) software stack. Supported by implemented effective management systems for Cyber Security (R155), Software Update Management System (R156) and a Safety Management System (SMS) (in compliance to Automated Lane Keeping System (ALKS) (R157)), the organizations have to ensure safe and secure development, deployment and operation to

Investigation on the Impact of High-Temperature Calendar and Cyclic Aging on Battery Overcharge Performance

2022-01-0698

03/29/2022

With the degradation of lithium-ion batteries, the battery safety performance changes, which further influences the safe working window. In this paper, the pouch ternary lithium-ion battery whose rated capacity is 4.2 Ah is used as the research object to investigate the impact of the high-temperature calendar and cyclic aging on tolerance performance. The overcharge-to-thermal-runaway test is performed on the fresh cell and aged cell (90% SOH). The inflection point of voltage for aged cells appears earlier than that of the fresh cell, while the voltage corresponding to the inflection point is the same for them, which means that the voltage at which lithium plating occurs is the same. However, the voltage plateau and the crest voltage before thermal runaway of aged cell are significantly higher than that of the fresh cell. Besides, ohmic heat, reversible heat, and side reaction heat make contribution to the thermal runaway triggering. Among them, the side reaction heat plays a dominant

Aviation Oxygen Safety Management System Analysis

2018-01-600104/15/2018

Oxygen has been a significant variable in flight operations for nearly 60 years. Today, the use of oxygen is almost synonymous with rocket, jet and turbo-prop operations affecting more than 45,000 aircraft worldwide. Today’s pilot flies farther, higher and longer than ever before, and does so at an ever increasing frequency. While the past 60 years have yielded tremendous advances in propulsion, avionics, materials and many other areas, oxygen and its role in aviation has remained largely stagnant. Although considered a major aircraft system and an essential component in high altitude operations, the orthodox mantra of ‘engineering it better’ has produced only limited results, most of them in the area of dispensation equipment (masks). In recent years Aeronautical Data Systems and collaborative entities have begun working to create a standardized and comprehensive aviation oxygen safety management system. This paper includes a general examination of what a new aviation oxygen doctrine

Avoiding Safety Scandals by Controlling the Risk of Material Changes

2017-01-0373

03/28/2017

Achieving functional safety in mechatronic systems with growing product functionality is a major challenge in systems engineering. Following the current discussion, this challenge is mostly allocated to electronics and software development. For most of the scenarios this focus is feasible. Product design - the construction of the product - defines the properties and the appearance of the product by shape, material and assembly. So, the product design is often not under control of the safety management system. A hazardous deviation of part shape can be easily identified after the parts product or at least at its mounting. A wrong assembly is controlled by assembly documentation or data (e.g. screw torques) and identified at end of assembly line checks. The identification of a hazardous material choice depends on the product material class. Product materials can be separated into two classes: passive or active materials. Passive materials (e.g. car body) can be distinguished in as

Determining a Safety Baseline for Unmanned Aircraft Systems

2011-01-2686

10/18/2011

Unmanned Aircraft Systems (UAS) emerge as a viable, operational technology for potential civil and commercial applications in the National Airspace System (NAS). Although this new type of technology presents great potential, it also introduces a need for a thorough inquiry into its safety impact on the NAS. This study presents a systems-level approach to analyze the safety impact of introducing a new technology, such as UAS, into the NAS. Utilizing Safety Management Systems (SMS) principles and the existing regulatory structure, this paper outlines a methodology to determine a mandatory safety baseline for a specific area of interest regarding a new aviation technology, such as UAS Sense and Avoid. The proposed methodology is then employed to determine a baseline set of hazards and causal factors for the UAS Sense and Avoid problem domain and associated regulatory risk controls

Managing Risk Reduction using a Relative Risk Prioritization Tool

2007-01-387109/17/2007

The Safety Management System (SMS) provides an environment where undesired events (proactively or reactively identified) are evaluated for the effect on safety using Risk Analysis. When the risk is evaluated, an interim risk reduction (mitigating action) may be applied to reduce the risk to a level that allows operations for a longer period before the safety issue is fully resolved. The risk assessment provides a means of evaluating the risk level and it may be difficult to quantify the “benefit” of interim mitigations that will reduce the risk. Prioritization of issues in the same risk category of the Risk Matrix is often simplified to a schedule and logistics basis of the final corrective action and often does not adequately show the benefit of the interim mitigating actions taken. Employing a concept used in System Reliability Analysis, the Design / Process Failure Modes and Effects Analysis (Design FMEA as defined in SAE J1739) uses a Risk Priority Number as a tool to identify the
