The compressor casing in a jet engine is an extremely valuable part that requires protection against blade tip abrasion, while aiming for the tightest distance between the case and blade tip for optimal compressor performance. Casings are made of high performing metals to sustain the mechanical conditional constraints as well as the harsh environment, debris and pollutant that can damage various parts. This critical area needs to avoid pollutant release in the downstream part of the jet engine.

Launch Vehicle Engine Turbopump
Category
Special Sizes & Shapes
3 min
Description
A launch vehicle uses a turbopump that is driven by a hot gas turbine. Due to high levels of horsepower, RPM, flow rates and pressures in this system, specific design features, materials, and fabrication methods must be used to ensure high performance as well as space flight levels of reliability. For static sealing applications in this area, metal seals are used to prevent leakage of a fluid through a joint that has no relative motion of the mating surfaces.

Compressor Variable Stator Vane Bushings
Category
Critical Applications
2 min
Description
At different speed regimes in the jet engine, the airflow in the compressor is regulated by variable stator vanes (VSV), which are generally located at the initial stages of the high pressure compressor. This area experiences relatively high pressure and high temperature that progressively increases with modern engine performances.

Jet Engine Lubrication Systems
Category
Critical Applications
3 min
Description
As manufacturers continue to improve the efficiency of jet engines, this results in the increase of temperatures throughout these systems. One example is High Temperature Stability (HTS) lubrication oils that are conveyed through a complex circuit and subjected to large temperature variations as well as strong vibration. These oils have been developed to sustain the harshest conditions in order to cool down engine parts and lubricate bearings.

Power Generation Natural Gas Turbine
Category
Critical Applications
4 min
Description
A natural gas turbine is a type of internal combustion (IC) engine, converting the heat produced by natural gases into mechanical energy. This energy is then supplied to power generators that produce electricity for residential and industrial use. Gas turbines are used to power aircraft, trains, ships, electrical generators, pumps, gas compressors, and tanks. There are three significant manufacturers: General Electric of the US, Siemens of Germany and Mitsubishi Hitachi Power Systems of Japan.

Hydraulic Downhole Drilling Jar
Category
Critical Applications
2 min
Description
Operated on land, offshore or ultra-hot boreholes, hydraulic downhole drilling jars are rather versatile and help to free and move the drill pipe components in the event that they become stuck in the formation. They are critical, significantly reducing the risk of expensive equipment loss.
