Help: Master Thesis in Aeronautical Engineering

[jmps22]

Hello guys, as the title stated I´m really at a standstill and need help.

I´m a BsC graduate in Mechanical Engineering, but at my employers will I´m developing my masters thesis in Aeronautical engineering. Title: Thermal and Aerodynamic Evaluation of a Piston-Engined MALE UAV

My tasks are the following:
- Design the engine nacelle (I already designed the general shape)
- size the inlets for intake, cooling, etc
- validate the CFD simulation

But I´m damned stuck in the process. Anywhere I look I can´t find a clear guide on what equations I need to solve in order to size the inlets and outlets, like how the hell am I supposed to know how big they should be. I find it hard to believe no other student developed a thesis similar to mine, a clear step-by-step guide on the matter. Either that or I´m taking a very wrong look at the subject.

I really don´t know guys, I need help finding research material, good articles, thesis and books that an take me from a blank page to a palpable solution.

Coming from a different area of study altogether isn´t really woeking in my favour.

whilst maybe not answering the question, Hoerner "Fluid Dynamic Drag" has a section on internal flows (which includes scoops) so that may help.

I'd've thought (as it seems you did) that the airflow demands of a piston engine were well understood (and analyzable).

Maybe basic airplane design books (Ramyer, Torenbeek) would give ideas.
Surely there's something about designing the installation of a piston engine on a plane ... even if it is just rules of thumb ?

Did you try googling "how to design an airplane engine intake" ? ... there seemed to be lots of hits.

I think you need JB Heywood and Philip Hubert Smith.
