This AIR provides information about the specific requirements for missile hydraulic pumps and their associated power sources.
The intent of this specification is for the procurement of 7781 glass fabric epoxy prepreg product with 250 °F (121 °C) cure for aerospace applications; therefore, no qualification or equivalency threshold values are provided. Users that intend to conduct a new material qualification or equivalency program must refer to the production quality assurance section (see 4.3).
This SAE Aerospace Information Report (AIR) developed by a broad cross section of personnel from the aviation industry and government agencies is offered to provide state-of-the-art information for the use of individuals and organizations designing new or upgraded turboshaft engine test facilities. This document is also applicable to turboprop engines tested with a dynamometer as load absorption device, as they are basically tested as turboshaft engines. For propeller-equipped turbofan testing facilities design considerations, see 2.1.7.
The purpose of this SAE Aerospace Information Report (AIR) is to provide management, designers, and operators with information to assist them to decide what type of power train monitoring they desire. This document is to provide assistance in optimizing system complexity, performance, and cost effectiveness. This document covers all power train elements from the point at which energy in a turbine or electric engine is converted via a gear train to mechanical energy for propulsion purposes. The document covers aircraft engine driven transmission and gearbox components, their interfaces, drivetrain shafting, drive shaft hanger bearings, and associated rotating accessories, propellers, and rotor systems as shown in Figure 1. For guidance on monitoring additional engine components not addressed herein (e.g., main shaft bearings and compressor/turbine rotors), refer to ARP1839. This document addresses rotary and fixed wing applications for rotor, turboprop, turbofan, prop fan, and lift fan
This SAE Recommended Practice covers the design and application of primary on-board wiring distribution system harnesses to road vehicles. This document applies to any wiring system which contains one or more circuits operating between 50 V DC or AC RMS and 600 V DC or AC RMS excluding automotive ignition cable.
This SAE Information Report is intended to be used for routine (or periodic) monitoring of filling station performance. It is not intended to provide process quality control requirements for any portion of the product delivery cycle.
This SAE Information Report establishes the Use Cases for communications and customer-focused Key Performance Indicators (KPI) between plug-in electric vehicles (PEVs) and their customers. The Use Case Scenarios define the information to be communicated related to customer convenience features for charge on/off control, charge power curtailment, customer preference settings, charging status, electric vehicle supply equipment (EVSE) availability/access, and electricity usage, plus customer information resulting from conflicts to charging preferences. It also addresses the KPI that can provide a uniform set of metrics to quantitively assess the charging experience. This document only provides the Use Cases that define the communications requirements to enable customers to interact with the PEV and the KPI to optimize their experience with charging a PEV. Specifications such as protocols and physical transfer methods for communicating information are not within the scope of this document.
This SAE Recommended Practice summarizes the conformance requirements for digital communication between the PEV and EVSE and establishes the interoperability requirements for successful charging sessions. This first version includes charging conformance summary for both the vehicle and EVSE and updates from CharIN with modifications, additions, and deletions to improve successful charging sessions. The summary of all existing charging/discharging standards, conformance, and functional categories will be updated in subsequent updates, and message/signal/values that would cause an interoperability issue will be clarified as this leads to diagnostic codes the vehicle/EVSE/Charge Point Operator and others can view to let the customer know what specific issue led to a failure to charge or discharge. This additional effort is ongoing and will be expanded in the next version update as this becomes more mature.
xEVs involved in incidents present unique hazards associated with the high voltage system (including the battery system). These hazards can be grouped into three categories: chemical, electrical, and thermal. The potential consequences can vary depending on the size, configuration, and specific battery chemistry. Other incidents may arise from secondary events such as garage fires and floods. These types of incidents are also considered in the recommended practice (RP). This RP aims to describe the potential consequences associated with hazards from xEVs and suggest common procedures to help protect emergency responders, tow and/or recovery, storage, repair, and salvage personnel after an incident has occurred with an electrified vehicle. Industry design standards and tools were studied and where appropriate, suggested for responsible organizations to implement. Lithium ion (Li-ion) batteries used for vehicle propulsion power are the assumed battery system of this RP. This chemistry is
This specification covers quality assurance sampling and testing procedures used to determine conformance to applicable specification requirements of wrought aluminum alloy and wrought magnesium alloy mill products (except forging stock), and includes quality assurance and testing procedures for rolled, forged, and flash welded rings (see 8.3).
