I have spent an inordinately long period of time resolving the intricacies in combustor diffuser. Considering the lower temperatures we are dealing with, pressure losses can be rather devastating. As a result, I looked at a myriad of texts and methods to develop our pressure model for our combustion system.…
The low pressure (LP) fan and high pressure (HP) compressor are designed in a similar manner. These both suffer from design problems that are exacerbated by low hub/tip (h/t) ratio blades. One such problem is blade twist. We wanted to compare four vortex theory models, including Mixed-Vortex swirl distribution and three…
The axial flow turbofan HP compressor and turbine were, and continue to be, a battle between size, efficiency, and power. These two components affect the overall performance of the engine. While the design is still an on-going challenge, I can see the fun parts coming. Materials and elegantly designed component…
I have been involved in a small footprint turbofan for a few years now. While the overall parameters of each engine section are understood, the intricacies of achieving each requirement are mind-boggling. Currently Aerospace Research and Development Group, LLC (AeroRND) is neck deep in the annular combustor design challenges (burner…
I have studied turbofan theory and design for over 3 years straight. My pet project, a small footprint turbofan, came with me to Aerospace Research and Development Group, LLC. (AeroRND). The project has taken on new dimensions and has grown a life of its own (like Frankenstein, only the Mel…
