Development and Applications of MIL-STD-1553

MIL-STD-1553, Aircraft Internal Time Division Command/Response Multiplex Data Bus, is a military standard which has become one of the basic standardization tools being used by the DOD for avionic interfaces. The standard describes the method of communication and the electrical interface requirements for devices using this standard. The 1 Mbps serial communication bus is the prime integration scheme for electronic devices in military avionics today. This paper addresses the application of the standard to military avionic integrations, describes the scope of the standard, the technical issues resolved in selecting the particular approach, and describes several military avionic examples using the standard.

Small Steps to Big Savings with ECM - (An Old Friend with a New Name)

The exploration of substantial money-saving areas of suitable usage for ECM (Electrochemical Metallizing) on aircraft components which are not in the purview of the original equipment manufacturer. The focus of the paper is upon the less spectacular maintenance opportunities rather than the much discussed repair of landing gear and engine components, all of which are strictly controlled by manufacturer's specifications because of safety considerations. Non-critical parts only require documented engineering specifications which are controlled by internal corporate engineering management. Our objective is to present areas of cost savings available to maintenance departments which have frequently been overlooked in the past. The perceived need is for some presentation of examples of applications which can be found in the normal day-to-day operations of aircraft maintenance activities so that similar opportunities may be identified and acted upon.

Engine Life Measurement and Diagnostics: The Future Direction for the Air Force

Major improvements in gas-turbine engine life management and diagnostics can be achieved using artificial intelligence. More effective use of data collected in flight will be possible, post flight maintenance will be expedited, and unnecessary engine removals eliminated. Most importantly, real-time measurement of life consumption would enable the safe life of fracture critical components to be fully used before their retirement. A comprehensive on-board life measurement and diagnostics system for gas-turbine engines is necessary to support probabilistic design and life prediction methodologies for gas turbine engines and the introduction of two-level maintenance in the Air Force.

Aircraft Gas Turbine Engine Health Management System Guide

This SAE Aerospace Recommended Practice (ARP) examines the whole construct of an Engine Health Management (EHM) system. This keystone document gives a top-level view and addresses EHM description, benefits, and capabilities, and provides examples. This ARP purposely addresses a wide range of EHM architectures to demonstrate possible EHM design options. This ARP is not intended as a legal document and does not provide detailed implementation steps, but does address general implementation concerns and potential benefits. Other SAE documents (Aerospace Standards, Aerospace Recommended Practices, and Aerospace Information Reports) address specific component specifications, procedures and "lessons learned".

Artificial Intelligence Application to Advanced ECLS Systems

Space Station preliminary design studies examined the role of advanced automation and artificial intelligence to facilitate ECLSS control and diagnostics. Advanced automation techniques using independent embedded controllers were selected for the initial station, especially for centralized processes such as water recovery, air revitalization, and waste management. This paper examines the role that advanced computer capabilities can play to enhance advanced missions such as growth station, Moon and Mars exploration. The benefits of artificial intelligence are presented from both the expert system and learned system perspective.

Unsettled Topics on the Use of IVHM in the Active Control Loop

The growth in global economies has led to a world that has become much more mobile in the last few decades. The number of enplanements has increased and is expected to continue to do so at an annual average rate of 1.8% through 2039 [1]. Prior to the COVID-19 pandemic, the number of aircraft in service was expected to increase annually to meet the travel demand. Next-generation, more-complex aircraft were scheduled to replace the older aircraft at a pace that still allowed sufficient capacity to meet the increasing demand. The events of 2020 have driven the industry to accelerate retirement of older aircraft while deferring the introduction of new aircraft. While the length of the industry recovery period cannot be predicted, most analysts believe that demand for travel will return once a vaccine is widely available.

Molecular Origins of ION Mobility Spectra: Towards Artificial Intelligence

During the last year, the principles and predictive tools for this analyzer have been advanced beyond the nominal understanding considered heretofore acceptable for specialized uses of IMS. The importance and need for these advances reside in the creation of automated intelligence (to minimize the need for human resources) and in the formation of tools for the identification of chemicals not previously characterized by IMS. In our findings, IMS spectra were found to arise from considerations both of proton affinities in the initial event of ion creation and of ion stabilities in the non-equilibrium, uni-polar drift region. Aliphatic amines were systematically explored and kinetic measurements were made on ion stabilities and used in modeling the origins of ion mobility spectra. Neural networks were used to explore an existing data base and results revealed hitherto unknown properties of ion mobility spectra.

Next-Gen Maintenance Framework for Urban Air Mobility Vehicles

Urban Air Mobility (UAM) vehicles are set to revolutionize the mobility of man and material in near future. One of the key areas to explore is how operational efficiency can be maximized through the next generation Maintenance framework. The UAM operational models may fundamentally change how aircraft maintenance is conducted. An important aspect of UAM is low altitude flying. This enables cellular technologies to be leveraged for air-to-ground as well as air-to-air communication. This implies a low cost, high speed air-to-ground data pipe is available, which leads to the concept of Digital Twin to be leveraged to optimize the operation and maintenance. This enables near real time availability of the state of UAM vehicle and its subsystems, even when it is flying. This paper captures the Next-Gen Maintenance framework along with several value-added services that can be built around it.
