Abstract Ever increasing requirements for vehicle performance, fuel economy and emissions have been driving the development and adoption of various types of hybrid powertrains. There are many different configurations of hybrid powertrains, which may include such components as engine, generator and inverter, battery pack, ultracapacitor, traction motor and inverter, transmission, and various control units. A hardware-in-the loop (HiL) testing solution that is flexible enough to accommodate different types of hybrid powertrain configurations and run a range of test scenarios is needed to support on-going development activities in this field. This paper describes the design and implementation of such a HiL testing system. The system is centered on a high performance, real-time controller that runs powertrain, driveline, vehicle, and driver models.

ARP4755C
This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of turboprop and turboshaft engines. This Aerospace Recommended Practice (ARP) shall apply to both dynamometer and propeller based testing. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine.

AS7477F
This document covers bolts and screws made from a corrosion and heat resistant, precipitation hardenable iron base alloy of the type identified under the Unified Numbering System as UNS S66286. The following specification designations and their properties are covered: AS7477: 130 ksi minimum ultimate tensile strength at room temperature 70 ksi stress-rupture strength at 1200 °F; and AS7477-1: Inactive for Design; AS7477-2: 130 ksi minimum ultimate tensile strength at room temperature 78 ksi minimum ultimate shear strength at room temperature. Classification: 130 ksi minimum tensile strength at room temperature 1200 °F maximum test temperature of parts.

Primarily for aerospace propulsion system applications where a good combination of fatigue resistance, tensile strength, shear strength, and resistance to relaxation at elevated temperatures is required.

ARP1533C
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.

ARD6888
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.

ARP6320
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).
