The logistics of the aerospace aftermarket raises a number of very interesting challenges from the perspective of electronic contracting. This is a highly dynamic domain, where contracts are established between airlines and engine manufacturers, as well as between engine manufacturers all the way down the supply lines, providing a particularly illustrative showcase for the technologies develope...

A Micro Gas Turbine (MGT) can be considered as an alternative to the internal combustion engine as a range extender for electric vehicles. The MGT produces less raw exhaust gaseous emissions such as HC and CO in aerospace and static applications compared to the internal combustion engine. In addition, the MGT weight is less than an equivalent internal combustion engine and potentially can reduc...

Imagine yourself looking out the window on a commercial flight at the aircraft engine outside. For four years, I worked at Honeywell Aerospace as product design engineer in a research team investigating flutter and forced response issues in turbomachinery for aircraft engines. Flutter is an aeroelastic issue that can cause near-instantaneous and catastrophic part failure. It results from the un...

structural steels with very high strength levels are often referred to as ultrahigh-strength steels (uhss). the usage of uhss has been extensively studied in aerospace industries and offshore platforms. in this study, medium carbon low alloy steel (ams6305) was thermomechanicaly treated to obtain an ultra-high strength bainitic steel for aircraft engine compressor disk. a novel themomechanical ...

in this work, the feasibility study for design of a laboratory sample rde which has an annular geometry with diameter of 76 mm and length of 101 mm has been performed. detonation engines are expected to be used as propulsion system in aerospace applications in the future. several types of detonation engines are currently under examination, including the rotating detonation engine (rde). first, ...

In today’s business climate, aerospace companies are more than ever in need of rational methods and techniques that provide insights as to the best strategies which may be pursued for increased profitability and risk mitigation. However, the use of subjective, anecdotal decision-making remains prevalent due to the absence of analytical methods capable of capturing and forecasting future needs. ...

Model-Based Design with automatic flight code generation is used to develop a variety of aerospace electronic systems including integrated avionics, jet engine controls, and flight control systems. The software deployed in these systems undergoes rigorous verification and validation because the consequences of software failure are severe. New code checking and analysis tools have recently emerg...

Demand for lower fuel consumption, more power and improved reliability keeps engine manufacturers constantly renewing their market offerings. Simultaneously, the growing number of aircraft models on the market, due to both the emergence of the very light jet (VLJ) segment and the numerous derivative designs aircraft makers are marketing, demands an ever expanding range of engines. In its busine...

Active infrared thermography is a fast and accurate non-destructive evaluation technique that is of particular relevance to the aerospace industry for the inspection of aircraft and helicopters' primary and secondary structures, aero-engine parts, spacecraft components and its subsystems. This review provides an exhaustive summary of most recent active thermographic methods used for aerospace a...
