The Future of EMI Shielding Is Lightweight, Flexible, and Ready for Flight25AERP09_0509/01/2025
Modern military aircraft represent some of the most complex electronic environments ever engineered. These platforms integrate advanced avionics, radar systems, data links, and communication networks that must function seamlessly in hostile, high-frequency environments. In these mission-critical contexts, electromagnetic interference (EMI) poses a silent but serious threat that can degrade signal integrity, cause crosstalk between systems, or even lead to mission failure. The combination of increasing data rates, higher frequencies, and more complex electromagnetic environments demands shielding solutions that can deliver superior performance while contributing to overall system weight reduction. This challenge has driven innovation toward advanced materials that maintain electrical effectiveness while dramatically reducing mass.

Determining Worst-Case Execution Time Bounds for Multi-Core Processors2025-01-015505/02/2025
Demonstrating deadline adherence for real-time tasks is a common requirement in all safety norms. Timing verification has to address two levels: the code level (worst-case execution time) and the scheduling level (worst-case response time). Determining which methodology is suited best depends on the characteristics of the target processor. All contemporary microprocessors try to maximize the instruction-level parallelism by sophisticated performance-enhancing features that make the execution time of a particular instruction dependent on the execution history. On multi-core systems, the execution time additionally is influenced by interference effects on shared resources caused by concurrent activities on the different cores, which are not controlled by the scheduling algorithm. In the avionics domain, the new FAA AC 20-193 / EASA AMC 20-193 guidance documents formalize predictability aspects of multi-core systems and derive adequate measures for timing verification.

Assignment Criteria for Function Allocation to Commercial Aviation System Security Domains2025-01-015605/02/2025
Aircraft cabin management is characterized by operational and business processes. Both are defined as a logical sequence of activities that occur during the flight. While the operational process includes activities to ensure flight safety, such as take-off, cruise and landing, the business process activities are related to adding value to the customer, i.e. the passenger. They are to be certified by the authority as a part of the aircraft type certification. These processes are defined by the airline and are described as part of the airline’s business model. While the scope of operational processes for passenger safety within the aircraft cabin should remain as unchanged as possible, the increasing competitive pressure on airlines is leading to a constantly rising number of services in the cabin. To prevent compromising cabin safety from increased cabin crew workload during the cruise phase, there is a growing trend toward digitizing operational and business processes. The digitized

Innovative High-Performance Active Dampers for Effective Mitigation of Helicopter Main Rotor Vibrations2025-01-016305/02/2025
Helicopter vibrations, primarily generated by the main rotor-gearbox assembly, are a major source of concern due to their impact on structural integrity, cockpit instrument durability, and crew comfort. These vibrations are mainly transmitted through the gearbox’s rigid support struts to the fuselage, leading to increased cabin noise and potential damage to critical components. This paper presents a solution for vibration mitigation which involves replacing traditional gearbox support struts with low-weight, high-performance active dampers. Developed by Elettronica Aster S.p.A., these active dampers are designed as electro-hydraulic actuators embedded within a compliant structure. The parallel nested configuration of the system enables high power densities and effective vibration control, significantly reducing the transmission of harmful vibrations to the fuselage. The comprehensive model-based design process is detailed, describing the development and use of a high-fidelity physics

Fault-Tolerant Control of a Quadcopter Using Reinforcement Learning01-18-01-000603/03/2025
This study presents a novel reinforcement learning (RL)-based control framework aimed at enhancing the safety and robustness of the quadcopter, with a specific focus on resilience to in-flight one propeller failure. This study addresses the critical need of a robust control strategy for maintaining a desired altitude for the quadcopter to save the hardware and the payload in physical applications. The proposed framework investigates two RL methodologies, dynamic programming (DP) and deep deterministic policy gradient (DDPG), to overcome the challenges posed by the rotor failure mechanism of the quadcopter. DP, a model-based approach, is leveraged for its convergence guarantees, despite high computational demands, whereas DDPG, a model-free technique, facilitates rapid computation but with constraints on solution duration. The research challenge arises from training RL algorithms on large dimension and action domains. With modifications to the existing DP and DDPG algorithms, the

A Survey of Validation and Verification Methods for AI-Based Vehicle Functions12-08-04-003101/17/2025
This article provides a comprehensive review of existing literature on AI-based functions and verification methods within vehicular systems. Initially, the introduction of these AI-based functions in these systems is outlined. Subsequently, the focus shifts to synthetic environments and their pivotal role in the verification process of AI-based vehicle functions. The algorithms used within the AI-based functions focus primarily on the paradigm of deep learning. We investigate the constituent components of these synthetic environments and the intricate relationships with vehicle systems in the verification and validation domain of the system. In the following, alternative approaches are discussed, serving as complementary methods for verification without direct involvement in synthetic environment development. These approaches include data-oriented methodologies employing statistical techniques and AI-centric strategies focusing solely on the core deep learning algorithm.

Vision-Based Approach and Landing System (VALS)TBMG-5219412/01/2024
There are certain situations when landing an Advanced Air Mobility (AAM) aircraft is required to be performed without assistance from GPS data. For example, AAM aircraft flying in an urban environment with tall buildings and narrow canyons may affect the ability of the AAM aircraft to effectively use GPS to access a landing area. Incorporating a vision-based navigation method, NASA Ames has developed a novel Alternative Position, Navigation, and Timing (APNT) solution for AAM aircraft in environments where GPS is not available.
Trajectory Tracking Control for a Hexacopter UAV: A Constraint-Following Approach Guaranteeing Prescribed Performance2024-01-701311/15/2024
The development of low-altitude economy driven by aircraft has garnered significant attention from both academia and industry. The hexacopter unmanned aerial vehicle (UAV) is an important component of low-altitude aircraft. Although it has not been as widely used as the quadcopter UAV, the greater delivery capacity and enhanced fault tolerance sustain its promising development prospects. However, the trajectory tracking control, a fundamental task of hexacopter UAV, remains challenging if the control algorithm is required to work on the dynamics level with theoretical performance guarantees, since its position control has to be realized by its attitude control. This study proposes a novel trajectory tracking control with prescribed performance for the hexacopter UAV that works on the dynamic model. The proposed approach is established by a dual-loop constraint-following control with the state-transformation technique, where equality and inequality constraints are used to describe the

Controlling Aircraft—From Humans to Autonomous Systems: Rise of the MachinesEPR202402009/25/2024
Paris, June 18, 1914: Crowds gathered at the “Concours de la Sécurité en Aéroplane” to witness 21-year-old Lawrence Sperry demonstrate his newly invented gyroscopic stabilizer. With his hands in the air, the device flew his Curtiss C-2 flying boat. Only a decade after the Wright brothers’ initial flight, the first n “autopilot” made its public debut. As impressive as this public demonstration was, it was merely a humble, although spectacular moment of foreshadowing. Even today—110 years later—the process of automating aspects of flight has not yet fully concluded, leading to deteriorating insight into the automatic behavior of aircraft systems, and even the waning of human instincts and intuition. Controlling Aircraft—From Humans to Autonomous Systems: Rise of the Machines covers the distancing of humans from their flying machines through more than a century-long process of “assisting” systems introduction, the positive and negative consequences of this process, and mitigation

Embedded Processing Advancements Enable Smarter, SWAP-Optimized Avionics Displays and Computers24AERP08_0508/01/2024
Aerospace manufacturers are leveraging multicore processors and modularity to design smarter cockpit displays and avionic computers that are smaller and capable of supporting more applications from a single line replaceable unit (LRU). Some are also starting to embed more of the processing required to enable cockpit display applications within the display itself, rather than having it enabled by an associated LRU. The development of new electric vertical takeoff and landing (eVTOL) aircraft and avionics companies changing their approach to the development of safety critical computers and aircraft networking technologies are some of the aerospace industry factors driving this design trend. In the U.S., the Department of Defense (DoD) embracing the Modular Open Systems Approach (MOSA) across the purchase of all new aircraft technologies is influencing design changes in cockpit displays and aircraft computers as well.
