Battery Powered Aircraft Tow Tractors - Factors for Design Consideration

AGE-3 Aircraft Ground Support Equipment Committee
  • Aerospace Standard
  • AIR1854A
  • Current
Published 2018-09-27 by SAE International in United States
This SAE Aerospace Information Report (AIR) identifies and summarizes the various factors that must be considered and evaluated by the design or specifying engineer in establishing the specifications and design characteristics of battery-powered aircraft tow tractors. This AIR is presented in two parts. The first part is simply a summarization of design factors that must be considered in establishing vehicle specifications and design characteristics. The second part refers particularly to the performance characteristics of an aircraft tow tractor. Some definitions, formulas, data, and an example are provided mainly for assisting the specifying engineers of potential buyers and users of aircraft tow tractors in the evaluation and comparison of their requirements with the performance capabilities of the various tow tractors offered by the tow tractor manufacturers. Although the design engineers could also use the formulas and data in their calculations of the performance specifications of aircraft tow tractors, this AIR is not intended to provide the methods and all data necessary for detailed calculations and design of a battery-powered aircraft tow tractor.

Published 2017-11-01 by Tech Briefs Media Group in United States

The Naval Research Laboratory (NRL) began operations in 1923 as the United States Navy's first modern research institution, and it continues today as one of the Navy's premier R&D resources. NRL's early 20th Century founders knew the importance of science and technology in maintaining naval power and preserving national security.

SAE's Mobility History Committee brings a trove of knowledge-and cool technology.

Engineers who have done patent searches know there's truth in the old saying: Few things are truly new under the sun.

Fire Suppression Modeling & Simulation Framework for Ground Vehicles

SAE International Journal of Transportation Safety

Alion Science & Technology-Steven Hodges
US Army TARDEC-Vamshi Korivi, Steven McCormick
  • Journal Article
  • 2017-01-1351
Published 2017-03-28 by SAE International in United States
The US Army Tank Automotive Research, Development and Engineering Center (TARDEC) has developed a unique physics based modeling & simulation (M&S) capability using Computational Fluid Dynamics (CFD) techniques to optimize automatic fire extinguishing system (AFES) designs and complement vehicle testing for both occupied and unoccupied spaces of military ground vehicles.The modeling techniques developed are based on reduced global kinetics for computational efficiency and are applicable to fire suppressants that are being used in Army vehicles namely, bromotrifluoromethane (Halon 1301), heptafluoropropane (HFC-227ea, trade name FM200), sodium-bicarbonate (SBC) powder, water + potassium acetate mixture, and pentafluoroethane (HFC-125, trade name, FE-25). These CFD simulations are performed using High Performance Computers (HPC) that enable the Army to assess AFES designs in a virtual world at far less cost than physical-fire tests.This methodology is applied to vehicle crew compartments for multiple scenarios using HFC227e + SBC powder which is the suppressant combination used in most US combat and tactical vehicles with crew fire protection systems. Predicted and test results match qualitatively very well for overall suppression time as well as…

Hydrostatic Hyperbaric Oxygen Treatment Chamber

  • Magazine Article
  • TBMG-23495
Published 2015-12-01 by Tech Briefs Media Group in United States

A hyperbaric chamber has been designed to achieve the goals of maximizing safety, minimizing complexity, and minimizing cost of hyperbaric chamber therapy. This design minimizes the volume of compressed gas in the chamber, and eliminates the need for complex gas mixing, carbon dioxide scrubbing, thermal management, and fire suppression systems. The simple pressurization system affords safe operation by minimally trained personnel. It requires only clean water and small volumes of compressed oxygen, and uses no electrical power. These features allow the chamber to be used in remote, undeveloped locations where hyperbaric oxygen therapy is currently not feasible.

Using NFPA Compliant Fire Apparatus Vehicle Data Recorders for Collision Investigation - Weldon Type 6444

D P Plant & Associates-David P. Plant
Fox Valley Technical College-Joseph E. LeFevre
Published 2015-04-14 by SAE International in United States
The use of Heavy Vehicle Event Data Recorders (HVEDRs) in collision analysis has been well recognized in past research. Numerous publications have been presented illustrating data accuracy both in normal operating conditions as well as under emergency braking conditions. These data recording devices are generally incorporated into Electronic Control Modules (ECMs) for engines or Electronic Control Units (ECUs) for other vehicular components such as the Anti-Lock Brake System. Other research has looked at after-market recorders, including publically-available Global Positioning System (GPS) devices and fleet management tools such as Qualcomm.In 2009, the National Fire Protection Association (NFPA) incorporated a Vehicle Data Recorder (VDR) component into their Standard for Automotive Fire Apparatus. The purpose of this was to “…capture data that can be used to promote safe driving and riding practices.” The Standard requires minimum data elements, recording times, and sample rates. These include vehicle speed, acceleration, throttle position, and other specified parameters. While the NFPA is not a regulatory agency, it serves to bring representatives from the fire suppression industry together to set accepted practices and…

Published 2015-03-01 by SAE International in United States

America's pony cars are a favorite of racers and fans alike, so racing them against each other is natural.

Detroit's pony car category has been consistently popular with both car buyers and racing fans, so it makes sense that the U.S. automakers would pursue venues for racing their sporty 2+2s against each other.
