New engine development is a costly endeavor and making the right decisions early in the engine design is extremely important. It requires multi-disciplinary consideration of the engine thermodynamic cycle coupled with preliminary aerodynamic design of key engine components. This includes evaluation of size, weight and cost parameters, with constraints imposed by aero, structural, geometrical, manufacturing, and material requirements.

A Cross-Over SCO2 System Application

The 2015 Paris Climate Talks (COP21) were successful in achieving consensus from 196 countries that climate change must be given significant attention. There was a particular focus on the release of carbon, in the form of carbon dioxide and carbon monoxide, as something that must be curtailed.

Designing Gas Turbines - It Really Requires Rocket Science

by Barbara Shea on Feb 16, 2017 3:31:58 PM

Engineers who design aircraft engines face a conundrum. Gas turbines in aircraft engines have to operate at very high temperatures for thermal efficiency and power output. These high temperatures put thermal stresses on the turbine blade materials. This requires that the blades be cooled. The most common way of doing this is using cooled air extracted from the engine’s compressor. Sadly, this air extraction decreases the thermal efficiency of the engine.
