This SAE Aerospace Information Report establishes a positive identification of the functions and, if applicable, the hazards and direction of flow of pipe, hose, tube, or electrical conduit lines.

SAE Aerospace Recommended Practice ARP1533 is a procedure for the analysis and evaluation of the measured composition of the exhaust gas from aircraft engines. Measurements of carbon monoxide, carbon dioxide, total hydrocarbon, and the oxides of nitrogen are used to deduce emission indices, fuel-air ratio, combustion efficiency, and exhaust gas thermodynamic properties. The emission indices (EI) are the parameters of critical interest to the engine developers and the atmospheric emissions regulatory agencies because they relate engine performance to environmental impact. While this procedure is intended to guide the analysis and evaluation of the emissions from aircraft gas turbine engines, the methodology may be applied to the analysis of the exhaust products of any hydrocarbon/air combustor.
Characteristics of vertical non-rotating balancing machines are described which make such machines suitable for balancing rigid unbladed gas turbine rotors or rotors with fixed, integral blades.

The purpose of this document is to specify the functional requirements for a miniature connector to be used for health monitoring purposes on aircrafts (including harsh environment such as the powerplant). It is actually a family of miniature connectors that is specified in this document for various uses (e.g. pin counts) and environments. This specification will be used by the SAE connector committee to work on a dedicated connector standard.
The standard applies to aero engine suppliers operating a self-release process as a delegated activity from the delegating organization. While primarily developed around the aero engine supply chain requirements, this standard can also be used in other industry sectors where a self-release process may be of benefit.

This Aerospace Recommended Practice (ARP) consists of methodologies for the measurement of non-volatile particulate matter (nvPM) emissions at the exit plane of aircraft gas turbine engines. The methods describe means of sampling and measuring particle mass concentration, particle number concentration and reporting of emissions indices through the use of an appropriate sampling system and instrumentation that goes beyond the measurements of visible obscuration as described in ARP 1179 for Smoke Number (SN).
WIP Standard
The standard will apply to (but not necessarily be limited to) cables, line impedance stabilization networks, pre-amplifiers, attenuators, current probes, etc.

This method is designed to evaluate the coking propensity of synthetic ester-based aviation lubricants under single phase flow conditions found in certain parts of gas turbine engines, for instance in bearing feed tubes. This method is applicable to lubricants with a coking propensity, as determined by this method, falling in the range 0.01 to 3.00 mg.
This SAE Aerospace Standard (AS) provides classical propulsion system performance parameter names for aircraft propulsion systems and their derivatives, and describes the logical framework by which new names can be constructed. The contents of this document were, originally, a subset of AS755E. Due to the growing complexity of station numbering schemes described in AS755, and a desire to expand the original document's nomenclature section to include a fuller representation of "classical" (legacy use) names, a decision was made to separate its "station numbering" and "nomenclature" content into two separate documents. This document, then, was created using the "nomenclature" half of AS755E. Both documents will continue to be improved and revised as industry needs dictate. The parameter naming conventions presented herein are for use in all communications concerning propulsion system performance such as computer programs, data reduction, design activities, and published documents.
WIP Standard
This specification defines basic physical, chemical, and performance limits for 5 cSt grades of gas turbine engine lubricating oils used in aero and aero-derived marine and industrial applications, along with standard test methods and requirements for laboratories performing them. It also defines the quality control requirements to assure batch conformance and materials traceability, and the procedures to manage and communicate changes in oil formulation and brand. This specification invokes the Performance Review Institute (PRI) product qualification process. Requests for submittal information may be made to the PRI at the address in Appendix C, referencing this specification. Products qualified to this specification are listed on a Qualified Products List (QPL) managed by the PRI. Additional tests and evaluations may be required by individual equipment builders before an oil is approved for use in their equipment.

This SAE Aerospace Information Report (AIR) provides a performance station designation system for unconventional propulsion cycles and their derivatives. The station numbering conventions presented herein are for use in all communications concerning propulsion system performance such as computer programs, data reduction, design activities, and published documents. They are intended to facilitate calculations by the program user without unduly restricting the method of calculation used by the program supplier. The contents of this document will follow AS755 where applicable.
WIP Standard
This procurement specification covers aircraft-quality bolts and screws made of 6.0Al 4.0V titanium alloy and of 160 ksi tensile strength at room temperature. Primarily for aerospace propulsion system applications where high strength, light weight fasteners are required for use up to approximately 600 °F.

Characteristics of vertical hard-bearing balancing machines are described which make such machines suitable for gas turbine rotor balancing.

This document specifies the following: a. general dimensions and capacities; b. performance requirements; c. balancing speed ranges; d. drive power requirements; e. balancing machine spindle flange dimensions; and f. test procedures.

Proving rotors and associated test masses required for the performance tests are described in ARP4162.

Test procedures are described in detail and test log samples along with a polar diagram for evaluating the test results are furnished.

The predecessor document ARP588, ISO 2953, and the available technology of hard-bearing balancing machines have been considered in the preparation of this document.

This document was developed for hard-bearing balancing machines but may also be used for existing soft-bearing balancing machines.
