This SAE Aerospace Information Report (AIR) presents descriptions of several types of industrial and marine gas turbine engine starting systems.

The Aircraft Engine Starting and Auxiliary Power System Glossary presents definitions of terms commonly encountered and associated with aircraft engine starting and auxiliary power systems. Terms have been arranged alphabetically.

No scope available.

This specification covers the general requirements for pneumatic control valves for use with the starters on aircraft gas turbine engines. This specification shall be used in conjunction with AS943, ARP949, and AIR1639.

This document provides a brief description of the auxiliary power equipment that is available with enough description and pertinent comments to enable an engineer to make logical preliminary selection of the appropriate equipment for advanced military aircraft programs. The information has been kept as brief as possible to include the maximum amount of equipment in a relatively short document. It is not intended to replace textbook design analysis or detailed information available from the equipment suppliers. The document describes auxiliary power equipment. Auxiliary power is defined as follows: "Those elements of secondary power [defined as all aircraft nonpropulsive power generation and transmission] related to main engine bleed air and shaft power extraction or power generation separate from the main engines. Included are engine bleed air systems, remote engine driven gearboxes, engine starting systems, auxiliary power units, and emergency power systems."

This SAE Aerospace Information Report (AIR) covers basic aircraft engine start systems fundamentals. It presents various ground power sources and aircraft “on board” starting units. Also included are descriptions of start system components and interconnections which together comprise an engine starting system.

This Aerospace Information Report (AIR) reviews the factors to be considered in determining the location and arrangement for auxiliary power unit (APU) installations for airborne applications and reviews requirements for flight suitability. As treated in this discussion, the APU normally includes a power section (or engine), a starting system, an electronic control unit (ECU), a gearbox with accessory mounting pads, and an oil cooling system. The accessories that are driven by the APU, such as CSD's (constant speed drives), alternating current (AC) generators, hydraulic pumps, or air compressors, are not covered here except insofar as they make demands on the APU. The various installation components and systems that are covered here are outlined by the table of contents. Turbine-type APU's are by far the most highly developed and universally used airborne units, so their installation will dominate the discussion in this document.

This information report includes procedures for determining and presenting in standard form and terminology turbine engine starting and motoring characteristics. It further includes the requirement for substantiating the accuracy of the information presented.

This SAE Aerospace Information Report (AIR) presents a discussion of drag torques of engine accessories operating at cold temperature. Various conditions of temperature, speed, and acceleration rates are reviewed showing the merits of each method and recommending a standard test method.

This SAE Aerospace Information Report (AIR) presents information on gas energy limited propulsion engine starting systems employed in commercial and military applications and remote industrial sites. The types of systems discussed utilize solid propellant cartridge gas, monopropellant hydrazine gas, bipropellant gas, compressed stored gas, and cryogenic stored nitrogen. Presented information conveys design features, performance capabilities and system limitations with methods of computing results.

This specification establishes the requirements for the (TBS) jet fuel starter for the (TBS) gas turbine engine used in the (TBS) aircraft.
