Guidelines for Aerodynamic Assessment of Mass-Produced Cars and Light-Duty Trucks Using Computational Fluid Dynamics

2019-07-01
WIP
J3191
This document outlines general requirements for the use of Computational Fluid Dynamics (CFD) methods for aerodynamic simulation of mass-produced cars and light-duty trucks. The document provides guidance for aerodynamic simulation with CFD methods to support current vehicle characterization, vehicle development, vehicle concept development and vehicle component development. The guidelines presented in the document include Navier-Stokes and Lattice-Boltzmann based solvers.

Glycol Recovery Vehicle (GRV) – Self-Propelled

2017-06-12
WIP
ARP6954
This SAE Aerospace Resource Document (ARD) document covers the requirements for a self-propelled GRV, intended for use at airports to collect spent aircraft de-icing fluid (ADF) from the surface of de-icing areas. This unit will recover de-icing fluid from the surface, which will be stored in a containment unit on the vehicle. The GRV must be capable of night and day operations in all weather conditions, as required.

Snow Compressor

2017-07-28
WIP
ARP8000
This SAE Aerospace Recommended Practice (ARP) document covers the requirements for a Snowcompressor with carrier vehicle used to clear snow from airport operational areas by compressing the volume of collected snow into smaller volumes for loading into a hauling/dump truck or for depositing reduced-volume windrows for snow banking. The term carrier vehicle represents the various self-propelled prime movers that provide the power necessary to move snow and ice control equipment during winter operations. For two-stage rotary plows that primarily are used to cast heavy concentrations of snow away from airport operational areas such as runways and taxiways, see ARP5539.

In-Flight Thrust Determination for Aircraft with Thrust Vectoring

2022-06-14
AIR6007
The purpose of this document is to provide guidance on in-flight thrust determination of engines that are impacted by intentional or unintentional thrust vectoring. However, as indicated in the Foreword, the field of aircraft thrust vectoring is varied and complex. For simplicity and coherence of purpose, this document will be limited in scope to multi-axis thrust vectoring nozzles or vanes attached to the rear of the engine or airfame; single-axis thrust vectoring and unintentional thrust vectoring (fixed shelf or deck configuration) are special cases of this discussion. Specifically excluded from this scope are thrust vectoring created primarily by airframe components such as wing flaps, etc.; lift engines, propulsive fans and thrust augmenting ejectors; and powerplants that rotate or otherwise move with respect to the airframe.

Measurement Uncertainty Applied to Cost-Effective Testing

2013-07-09
AIR5925A
The report shows how the methodology of measurement uncertainty can usefully be applied to test programs in order to optimize resources and save money. In doing so, it stresses the importance of integrating the generation of the Defined Measurement Process into more conventional project management techniques to create a Test Plan that allows accurate estimation of resources and trouble-free execution of the actual test. Finally, the report describes the need for post-test review and the importance of recycling lessons learned for the next project.

EIAQAB7
This document has been formulated as a suggested guide in assisting EIA Engineering Department Panels and JEDEC Councils in cooperating with the Defense Department and other Federal agencies in the preparation of suggested reliability requirements for various types of electronic products as part of a program designed to enhance the reliability of defense and related equipment. The document is to be followed merely as a guide and is not intended to limit technical groups in the consideration of the factors to be taken into account in the development of reliability specifications for recommendation to the Government.

8000 psi Hydraulic Systems: Experience and Test Results

2004-03-18
AIR4002
Shortly after World War II, as aircraft became more sophisticated and power-assist, flight-control functions became a requirement, hydraulic system operating pressures rose from the 1000 psi level to the 3000 psi level found on most aircraft today. Since then, 4000 psi systems have been developed for the U.S. Air Force XB-70 and B-1 bombers and a number of European aircraft including the tornado multirole combat aircraft and the Concorde supersonic transport. The V-22 Osprey incorporates a 5000 psi hydraulic system. The power levels of military aircraft hydraulic systems have continued to rise. This is primarily due to higher aerodynamic loading, combined with the increased hydraulic functions and operations of each new aircraft. At the same time, aircraft structures and wings have been getting smaller and thinner as mission requirements expand. Thus, internal physical space available for plumbing and components continues to decrease.
