ARP6955
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.

The range of test conditions on the dynamometer shall be sufficient to determine the primary operating characteristics corresponding to the full range of vehicle operations. The characteristics to be determined are: a. Torque ratio versus speed ratio and output speed b. Input speed versus speed ratio and output speed c. Efficiency versus speed ratio and output speed d. Capacity factor versus speed ratio and output speed e. Input torque versus input speed

AMS6465E
This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of July 2009. It is recommended, therefore, that this specification not be specified for new designs. “NONCURRENT” refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. “NONCURRENT” specifications are available from SAE upon request.

AIR6027A
The information presented in this AIR is intended to provide designers of armed unmanned systems with guidelines that may be applied to ensure safe integration and operation of weapons on unmanned platforms. The guidelines have been developed from experiences gained in the design and operation of weapons on manned aircraft that have been accepted by relevant safety authorities in the USA and Europe and proven effective over many years. Whilst the guidelines have been developed from experience with aircraft operations, the concepts are considered equally applicable to non-aircraft systems, such as those used on the surface or undersea environments.

J2836/4_201706
This SAE Information Report J2836/4 establishes diagnostic use cases between plug-in electric vehicles and the EV Supply Equipment (EVSE). As Plug-In Vehicles (PEV) are deployed and include both Plug-In Hybrid Electric (PHEV) and Battery Electric (BEV) variations, failures of the charging session between the EVSE and PEV may include diagnostics particular to the vehicle variations. This document will describe the general information required for diagnostics and J2847/4 will include the detail messages to provide accurate information to the customer and/or service personnel to identify the source of the issue and assist in resolution. Existing vehicle diagnostics can also be added and included during this charging session regarding issues that have occurred or are imminent to the EVSE or PEV, to assist in resolution of these items.

J1342_201706
The techniques outlined in this SAE Recommended Practice were developed as part of an overall program for determining and evaluating fuel consumption of heavy-duty trucks and buses, but it is applicable to off highway vehicles as well. It is recommended that the specific operating conditions be carefully reviewed on the basis of actual installation data. Cooling requirements are affected by all heat exchangers that are cooled by the fan drive system. These may include radiators, condensers, charge air coolers, oil coolers, and others. Because of the variation in size, shape, configuration, and mountings available in cooling fans and fan drive systems, specific test devices have not been included. Using known power/speed relationships for a given fan, this procedure can be used to calculate the fan drive system’s power consumption for engine cooling systems using fixed ratio, viscous or speed modulating, and mechanical on/off fan drives including electronically activated fan drives.

ARP6481
This SAE Aerospace Recommended Practice (ARP) describes a method for assessing size dependent particle losses in a sampling and measurement system of specified geometry utilizing on the non-volatile PM (nvPM) mass and number concentrations measured at the end of the sampling system. The penetration functions of the sampling and measurement system may be determined either by measurement or by analytic computational methods. Loss mechanisms including thermophoretic (which has a very weak size dependence) and size dependent losses are considered in this method along with the uncertainties due to both measurement error and the assumptions of the method. The results of this system loss assessment allow development of estimated correction factors for nvPM mass and number concentrations to account for the system losses facilitating estimation of the nvPM mass and number at the engine exhaust nozzle exit plane.

J2945/3
This effort will serve for the development of a new standard to define requirements to support V2I weather applications interface in a connected vehicle environment. USDOT has provided funding for this standard and has requested that the Technical Committee (TC) approve using the Systems Engineering Process (SEP) as defined in J2945/0. Initial works in the field of road weather applications have been conducted by stakeholders from both the public and private sector. USDOT has offered a high level Concept of Operations for Road Weather Connected Vehicle and Automated Vehicle Applications to the TC as a basis for consideration to initiate the dialog for J2945/3. This Concept of Operations contains 8 Proposed Applications and 13 Operational Scenarios for the TC and V2I TF to consider. The TC also has material in SAE J3067 as a basis for its consideration. The focus is on information exchanges between the infrastructure and connected vehicles.
