The World of Civil Aerospace

IVHM Centre Cranfield University-Ian K. Jennions
  • Book
  • R-468
Published 2019-05-28 by SAE International in United States
Collaboratively written by eleven experts with extensive experience in the field of commercial aviation, The World of Civil Aerospace is a unique book that defines its own category. Covering the beginnings of commercial aviation, aircraft design and certification, manufacturing and testing, airline operation, maintenance and safety, among other topics, The World of Civil Aerospace shows the reader the fundamental (yet almost invisible) aspects of how the planes and airports we use every day actually function. The title, edited by Prof. Ian Jennions, from Cranfield University in the UK, came about from the desire to share the inner workings of what it takes to create, test, approve, certify and launch a new aircraft. Not mention how to maintain it and make the user experience of flying it positive. With the commercial aviation industry expected to continue to grow for decades to come, the challenges of keeping aircraft in the air safely, reliably and economically are enormous. Thousands of engineers, support personnel, maintainers and crews go to work every day with one goal in mind: to make…

Welded, Flash-Controlled, Low-Carbon Steel Tubing Normalized for Bending, Double Flaring, Beading, Forming, and Brazing

Metallic Tubing Committee
  • Ground Vehicle Standard
  • J356_201905
  • Current
Published 2019-05-09 by SAE International in United States
This SAE Standard covers normalized electric-resistance welded flash-controlled single-wall, low-carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, beading, forming, and brazing. Material produced to this specification is not intended to be used for single flare applications, due to the potential leak path caused by the Inside Diameter (ID) weld bead or scarfed region. Assumption of risks when using this material for single flare applications shall be defined by agreement between the producer and purchaser. This specification also covers SAE J356 Type-A tubing. The mechanical properties and performance requirements of SAE J356 and SAE J356 Type-A are the same. The SAE J356 or SAE J356 Type-A designation define unique manufacturing differences between coiled and straight material. Nominal reference working pressures for this tubing are listed in ISO 10763 for metric tubing, and SAE J1065 for inch tubing. SAE J356 is produced in straight lengths that undergo a secondary heat treat operation. SAE J356 Type-A tubing is heat treated in-line to…

Selecting Electric Traction Solutions for AGVs and Mobile Robots

  • Magazine Article
  • TBMG-34112
Published 2019-04-01 by Tech Briefs Media Group in United States

Smarter, better, faster, less expensive — those words are the mantra of today’s global economy. As organizations seek to streamline operations and do more with less, they increasingly focus on automated guided vehicles (AGVs) and similar vehicles to help get the job done. By 2022, analysts expect the global AGV market sector alone to hit $2.65 billion. To meet demand, OEMs will need traction technologies that perform unquestionably while remaining rugged, economical, and easy to install and maintain. Electric traction solutions deliver on all counts.

Welded Flash Controlled, High Strength (690 MPa Tensile Strength) Low Alloy Steel Hydraulic Tubing, Stress Relieved, Annealed for Bending, Double Flaring, Cold Forming, and Brazing

Metallic Tubing Committee
  • Ground Vehicle Standard
  • J2832_201902
  • Current
Published 2019-02-27 by SAE International in United States
This SAE Standard covers stress relieved electric resistance welded flash controlled single wall high strength low alloy steel tubing intended for use in high-pressure hydraulic lines and in other applications requiring tubing of a quality suitable for bending, double flaring,cold forming and brazing. Material produced to this specification is not intended to be used for single flare applications due to the potential leak path caused by the ID weld bead. The grade of material produced to this specification is of micro-alloy content. Nominal reference working pressures for this tubing are listed in ISO 10763 and SAE J1065. Brazed and/or welded tube assembly configurations made to specific geometry and components in association with this material may require qualification testing in accordance with ISO 19879. Cold forming the tube end configurations avoids this systemic testing by not compromising the structural integrity of the tube material. In an effort to standardize within a global marketplace and ensure that companies can remain competitive in an international market, it is the intent to convert to metric tube sizes, which will:…

Network Layer

Truck Bus Control and Communications Network Committee
  • Ground Vehicle Standard
  • J1939/31_201809
  • Current
Published 2018-09-13 by SAE International in United States
SAE J1939-31 Network Layer describes the requirements and services for Network Interconnection ECUs (NIECU) that enable electronic control units (ECUs) on a network segment to intercommunicate with other ECUs on different network segments of the vehicle network. This document defines various types of NIECUs. The information in this document applies only to ECUs that are intended to provide networking services. It is not necessary for an ECU to provide any of these services in order to be compliant with the SAE J1939 protocol.

Researchers Develop At-Home Pap Smear Test

  • Magazine Article
  • TBMG-28922
Published 2018-05-01 by Tech Briefs Media Group in United States

An at-home Pap smear test is designed to reduce anxiety associated with the procedure and give women more control over their health without interfering with their work or social life. The Domi Care, designed by industrial design graduate Lauren Emmerson and current senior Anastasia Miller, was recently awarded first place in the International Housewares Association Student Design Competition.

Application of CAE (Computer Aided Engineering) Superelement Technique for NVH (Noise, Vibration and Harshness) Attributes on a Trimmed-Body Vehicle Structure in Order to Assist Supplier Commodity Development Based Also on NVH Requirements

Ford Motor Company-Gimaezio Gomes Carvalho, Luis Guilherme Mariano Viana Martins
Published 2017-11-07 by SAE International in United States
The business environment is ever changing, several innovations have allowed companies to transcend borderlines and become global entities. While the opportunities are numerous so are the challenges. In this fiercely competitive global marketplace, success requires companies to pay closer attention to supplier relations. The relationship between an automotive industry and its suppliers is an example of it, so the application of CAE (Computer Aided Engineering) superelement technique may improve, in terms of NVH (Noise, Vibration and Harshness), the vehicle development efficiency, without compromising confidentiality directives. Most of NVH requirements must be tracked through Transfer Functions (TFs) analyses at response points located on the Trimmed-Body Finite Element Model (FEM), as for example: Point Mobility, Vibration Transfer Function (VTF) and Acoustic Transfer Function (ATF). As the Trimmed-Body is an assembly of sub-systems, some of them developed in-house and other by external suppliers, FEM and TFs must be cascaded to all sub-system developers, including external suppliers. Confidentiality directives do not allow FE models sharing with external suppliers, precluding commodities development by suppliers to be driven by NVH attribute…
