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 the gas generator energy is
transferred to mechanical energy for propulsion purposes. The document covers engine power train
components, their interfaces, transmissions, gearboxes, hanger bearings, shafting and associated
rotating accessories, propellers and rotor systems as shown in Figure 1.
This document addresses application for rotorcraft, turboprop, and propfan drive trains for both
commercial and military aircraft.
Information is provided to assist in;
a. Defining technology maturity and application risk
b. Cost benefit analysis (Value analysis)
c. Selection of system components
d. Selection of technology
e. Managing interface requirements
f. Defining information flow requirementsstrRefField
