Back in the sleeping compartment, completely unattended, automatic flight recorders and an automatic temperature recorder system continuously gather all possible information on the operation of the engines, controls, and performance of the airplane.

SAE EDGE Research Reports provide examinations significant topics facing mobility industry today including Connected Automated Vehicle Technologies Electrification Advanced Manufacturing

Uncertainty quantification The technique is a must for next-generation simulation tools. Oil-pump sizing Researchers from Hinduja Tech investigate options for low friction and power consumption. The future of Indian commercial aviation The growth in traffic that airport modernization has supported has also made a significant contribution to the local and national economies, while the improved infrastructure has been positive for the perception of India in the global market. Driving EVs toward lower cost The race ison to reduce battery and electric-drive systems cost while improving efficiency. Powering on Rolls-Royce's Chief Engineer discusses new technologies that inspire current R&D design and evaluation work as part of its strategic roadmap for future big commercial programs. HMIs extend beyond the cab Telematic functions are being integrated into multi-function user interfaces.

This SAE Aerospace Information Report (AIR) summarizes prior empirical findings (AIAA 2018-3991; Chati, 2018) to recommend a modified baseline fuel flow rate model for jet-powered commercial aircraft during taxi operations on the airport surface that better reflects operational values. Existing standard modeling approaches are found to significantly overestimate the taxi fuel flow rate; therefore, a modified multiplicative factor is recommended to be applied to these existing approaches to make them more accurate. Results from the analysis of operational flight data are reported, which form the basis for the modeling enhancements being recommended.

The TIMED spacecraft is implementing an Integrated Electronics Module (IEM) that contains several different spacecraft subsystems, like C&DH, S-band receiver and transmitter, solid-state recorder and more. The combination of all these subsystems into one box, normally packaged in separate card cages, has resulted in some challenging thermal design problems.

The Nano in retrospect A senior graduate student in the Department of Mechanical Engineering at the Indian Institute of Technology looks at the development of the world's cheapest car and its effect on Indian car users. A different riff on your basic two-seat electric car Markus Lienkamp, Chair of Automotive Engineering at the Technical University of Munich, is leading the Visio.M project, a German government-supported R&D effort to produce a low-cost, high-utility electric car that might attract the interest of the middle European mass market. Materials lead the way to vehicle mass reduction Reducing a vehicle's mass opens the door for a downsized engine and transmission, a lighter cradle and body structure, smaller wheels and brakes, as well as a weight-slimmed suspension. The start point for this ripple effect is materials.

This document defines general system architectural philosophy and specific design guidance for the design and interface of various cabin related equipment. System performance parameters are described for connectors, electrical interfaces, operational mode control/protocols, BITE reporting, reliability, environmental conditions, and software data loading. Supplement 7 defines an IEEE 802.11n compliant Cabin Wireless Access Point (CWAP) suitable for installation a wide variety of cabins. It also provides an update to the digital overhead monitor mounting provisions and connectors for compatibility with the CWAP definition.

ARINC 828-4 defines a common Electronic Flight Bag (EFB) interface that can support EFB installations and the associated software applications. Supplement 4 defines two new connectors that will provide power and Ethernet to the EFB, thus enabling a smaller and lighter footprint for EFB installation provisions.

Showing how it's done Engineers are using software to better manage product development data, and applying tools to a new class of problems. NASA goes deep The agency's new long-term space exploration program starts with a return to the moon and will ultimately enable future exploration of Mars and other solar system destinations. Farnborough preview In an event that happens just once every two years, bringing the multitudes together, it is important to get as much technology as possible into the open and to find solutions to hard problems. Seats under crash loading The FAA and academia have conducted aircraft seat drop tests to compare and contrast passenger crash protection. A fluid approach Aerospace engineers have started using CFD software earlier and earlier in the design process.

Pulse Plasma Nitriding for Aerospace Application Ruggedization of Electronics for Deployed Military Environments Migrating Advanced Signal Processing Technology to Rugged SFF Platforms Radar Recording Proves Next-Level System Performance As radar and electronic warfare systems contend with an increasingly crowded environment, recording tests, interactions, and conflicts provides insight that can help assure future triumphs. > Facing 5G New Radio (NR) Test Challenges Communicating Via Long-Distance Lasers The Purpose of Mixed-Effects Models in Test and Evaluation The simplest version of a mixed model-the random intercept model, where so-called random effects represent group-wide deviations from a grand mean-can account for day-to-day deviations in system performance while still allowing the results to be generalized beyond the few days of observed testing.

This standard establishes uniform test methods for testing electrical connectors.
