internal investigation made by EngineWorks is into axial rotary vane blade engines.
The engine type was designated EW-LSTE (Low Speed Turbine Engine). The above
layout turned out
to be expensive to produce and some items too delicate for
high-temperature operation. This engine is the first of five concept drafts. All 3D work for this engine was lost due to
a
server break-down. And that is how EngineWorks learned the important lesson of data-security and storage-safety. The 5th concept draft was selected for further investigation and three prototype LSTE engines were built throughout the period 2008 - 2013. 17 minor and major modifications have been integrated into designs. The last engine version, the EW-20CP, is operative, but illustrates that long-term maintenance is a concern by such an engine type. The development program was put on ice (but not cancelled) in early 2014. A spin-off technology has derived from the RVCE and LSTE technologies. This is the pressure amplification principle (see more under: Own research). Heat is converted into pressure, and pressure, can be expanded. The pressure amplification concept is attractive for the waste-heat market for recapturing low, middle and high grade heat at high efficiencies. A market segment that has today become utterly important. | |
