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… Continue reading The post Swirl Distribution in Low Hub/Tip Ratio Blades appeared first on Aerospace Research and Development Group, LLC .
