The engineering services industry has reaped success from outsourcing and globalization in recent years. One of the critical factors for achieving outsourcing success is identifying and assessing an engineering services partner who can meet an original equipment manufacturers’ (OEM’s) needs in all the markets it serves. Evaluations based on qualities such as an outsourcing partner’s
A traditional practice in the rotor dynamics analysis is to use beam models for both the lateral and the torsion analysis. Such an analysis limits the capabilities for the modern day design of high-speed machinery. The beam type one-dimensional models require good modeling techniques to approximate the three dimensional rotors. An analysis of this type
Maintainability assessment of an engine or unit helps in identifying and validating whether or not the actual design of an engine or unit meets the maintainability characteristics. Maintainability assessment is an important requirement while designing an aircraft engine because it determines whether Line Replaceable Units (LRUs) can be accessed for replacement or periodic inspection or
The heat transfer calculations for turbine flows are known to have a substantial degree of uncertainty. Therefore experimental verification of analytical predictions is needed. Properly done, metal temperature measurements could inform a designer about the existence of under-cooled or over-cooled locations, suggesting possible opportunities to improve engine thermodynamic and durability characteristics. The authors analyzed the
This paper investigates the accuracy of Uniform Crystal Temperature Sensors (UCTS) under transient conditions and describes a methodology for addressing sources of systematic error based on the findings. The study applies to the important task of thermal mapping of critical turbine parts during the engine development phase, for which UCTS is particularly well suited. A
The best piping configuration is the least expensive and offers the highest efficiency throughout its life term.This requires consideration of various factors such as total cost of ownership in addition to the total installation cost.
Despite 70 per cent of our planet being covered with water, it is still a dwindling resource. Saline water in seas and oceans makes up about 97 per cent of this amount and only 3 per cent can be counted as fresh water. The total usable freshwater supply for the ecosystems and humans is mere
The oil and gas equipment manufacturing sector is a high impact one. Any slippages in the process of manufacturing that result into faulty equipment may lead to complications at stages where reversing/ checking the error may not be possible. The manufacturers are therefore documenting their SOPs to maintain uniformity in processes and output across all
Hydroelectric power generation has been around since the late 19th century. Generally seen as a renewable, environment friendly, non-polluting, low-cost and highly reliable source of energy, some 150 nations have hydel-power projects today. Hundreds of hydro-generators installed more than 60 to 80 years ago still operate across the world, using old technology. Given the long-time
Today’s fast-paced industrial scenario demands a drastic reduction in the timeline of a new product – from the design phase to component release. Component conformance, where a part is certified to suit the physical dimensions of the end product, takes up a major chunk of any industrial product timeline. This technical paper examines the impact
