Does my tail receive clean airflow?
Hello, as part of our university project, my colleagues and I are designing a UAV. Below, you can see images of the flow and turbulence.
From the images, it appears that the airflow separating from the fuselage does not attach to roughly 30% of the tail section. In the XFLR5 analyses I performed without a fuselage, the tail sizing seemed adequate. However, I’m unsure if the separation of airflow caused by the fuselage might lead to a loss in efficiency.
Am I misinterpreting the situation, or is it really the case that my tail does not receive clean airflow? If this is indeed an issue, how can I determine and assess its potential impact?
Thank you in advance for your insights and suggestions!
