This SAE Aerospace Information Report (AIR) outlines a recommended procedure for evaluation of the vibration environment to which the gas turbine engine powerplant is subjected in the helicopter installation. This analysis of engine vibration is normally demonstrated on a one-time basis upon initial certification, or after a major modification, of an engine/helicopter configuration. This AIR deals with linear vibration as measured on the basic case structure of the engine and not, for example, torsional vibration in drive shafting or vibration of a component within the engine such as a compressor or turbine airfoil. In summary, this AIR discusses the engine manufacturer’s "Installation Test Code" aspects of engine vibration and proposes an appropriate measurement method.

This report is intended to provide the information to estimate the accessory load of a typical heavy truck or bus. The components covered include: air compressors, alternators, refrigerant compressors, engine cooling fans and power steering pumps. The values show an estimate of the average power requirements and duty cycles for these accessories. This report does not address loads required for engine operation. Required systems include those needed for engine performance such as fuel pumps and electronic control modules (ECM).
This SAE Recommended Practice is intended to apply to lamps, batteries, heaters, radios, and similar equipment for operation with mobile or automotive diesel engines. Twenty-four V systems have long been used for heavy-duty services because 24 V permit operating 12 V systems in series-parallel. Thirty-two V systems have been used for marine, railroad-car lighting, and other uses. Generators, storage batteries, starting motors, lighting, and auxiliary electrical equipment shall be for nominal system ratings of 12, 24, or 32 V as determined by the power requirements of the application. It is recommended that no intermediate voltages be considered. The combination of a 24 V starting motor and two 12 V batteries connected in series for cranking is considered practical where it can be adapted to the installation. The batteries are reconnected in parallel for charging from a 12 V generator/alternator and for operating lights and other auxiliary equipment, or charged separately and used
The electrical cranking system components, which include the battery, cables, and cranking motor, must be carefully selected to provide the necessary speed to start an engine under the most severe climatic conditions for which the system is intended. Engine cranking loads increase with cold temperatures, therefore, the initial selection of these components needs to consider low-temperature engine torque requirements. To insure an adequate electrical cranking system is obtained, it is important that proper test procedures are used for obtaining the cranking load requirements of the engine.
The purpose of this SAE Standard is to provide a standardized test procedure for generating engine performance maps.

Engine performance maps as specified by this code can be used in fuel economy simulation programs. This document is applicable to both four-stroke spark ignition (SI) and compression ignition (CI) engines, naturally aspirated and pressure charged, with or without charge air cooling.
This specification establishes the performance, qualification, acceptance limits, and identification for aeronautical engine high tension spark igniters.
SAE data file format for exchanging controlled periodic overload data. The object of this SAE Standard is to provide a simple, common methodology for exchanging the data from periodic overload fatigue tests. These tests consist of a single large fatigue cycle followed by a larger number of smaller cycles. The overloads are fully reversed fatigue cycles while the smaller cycles share a common mean and amplitude.
This Information Report describes eddy current testing, flux leakage testing, ultrasonic testing, and magnetic particle testing of steel tubing. The purpose of these testing methods is to expose flaws in the tube material or weld zone, such as discontinuities, seams, cracks, holes, voids, and other imperfections characteristic to the specific construction of the tubing. When agreed upon between the producer and purchaser, nondestructive testing is used in lieu of destructive hydrostatic pressure proof testing. Aircraft and Aerospace applications were not considered during the preparation of this document.

This standard defines five CM functions and their underlying principles. The functions are detailed in Section 5. The principles, highlighted in text boxes, are designed to individually identify the essence of the related CM function and can be used to collectively create a checklist of “best practice” criteria to evaluate a CM program. The CM principles defined in this standard apply equally to internally focused enterprise information, processes, and supporting systems (i.e., Enterprise CM - policy driven, supporting the internal goals needed to achieve an efficient, effective and lean enterprise), as well as to the working relationships supported by the enterprise (i.e., Acquirer/Supplier CM - contracted relationship to support external trusted interaction with suppliers). In an Enterprise CM context there are several methodologies for principle use by the enterprise: The principles of this standard provide direction for developing enterprise or functional CM plans focused on
This SAE Standard specifies test methods and general requirements for the determination of the electrical characteristic data of alternators for road vehicles. It applies to alternators, cooled according to manufacturer’s instructions, mounted on internal combustion engines. This document attempts to follow ISO 8854, dated 1988. ISO 8854 has been modified herein to reflect local market requirements and historical precedent.

The purpose of this SAE Recommended Practice is to provide standardized dimensions for mounting starting motors. (See Figures 1 through 4.) It is recommended that a full register diameter having a minimum depth of 2.54 mm (0.100 in) be provided in the flywheel housing to insure proper control of gear center distance and clearance between pitch diameters. The clearance between the starting motor pilot diameter and the register diameter in the flywheel housing should be 0.03 mm (0.001 in) minimum to 0.25 mm (0.010 in) maximum. Text noted with an asterisk in Figures 1, 2, and 3, should not exceed root radius of pinion in order to provide clearance for the flywheel. The face of the starting motor mounting flange should be relieved at its junction with the pilot diameter to avoid mounting interference with flywheel housing. For backlash allowance between the pinion and ring gear refer to SAE J543. Dimensional units—millimeter (inch)
