Oil debris monitoring in aero engines In a gas turbine engine, small particles or "chips" are generated at the point of wear, serving as an advanced warning that catastrophic failure will occur if the wear is not addressed. Health monitoring systems, such as oil debris monitoring, are used to find these small particles so that the wear can be resolved before it's too late. Indigenous powertrain development Customer needs and expectations on drivability, fuel economy, and safety has pushed Indian and multinational OEMs to think about the development of powertrains and gearboxes for local needs with global standards. The next wave of crash simulation As computing speed has improved and software itself has made significant speed and performance gains with each release, modeling tools are now quick enough to build high-quality, large, high-detail vehicle models in a very efficient manner.

This report lists documents that aid and govern the design, development, and utilization of aerospace electronic engine control systems. The report lists the military and industry specifications and standards that are commonly used in electronic engine control system design. However, this list is not necessarily complete. The specifications and standards section has been divided into two parts; a master list arranged numerically and a categorized list that provides a functional breakdown and cross reference of these documents. For specifications and standards, the issue available during the latest revision to this document is listed. Details of current revisions for many documents are available in the Department of Defense Index of Specifications and Standards (DODISS).

AIR7999
This SAE Aerospace Information Report (AIR) presents metrics for assessing the performance of diagnostic and prognostic algorithms applied to Engine Health Management (EHM) functions. This document consolidates and expands upon the metric information previously contained in AIR4985 and AIR5909. The emphasis is entirely on metrics and as such is intended to provide an extension and complement to such documents as ARP4176, which provides insight into how to create a cost benefit analysis to determine the justification for implementing an EHM system.

This document defines the process steps involved in collecting and processing engine test data for use in understanding engine behavior. It describes the use of an aero-thermal cycle model for reduction and analysis of those data. The analysis process may include the calculation of modifiers to match the model to measured data, and prediction of engine performance based on that analysis
