Help: Master Thesis in Aeronautical Engineering

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.

The appropriate Engine installation manual maybe of help

There is a bunch of War reports on this on the NASA tech server mostly with the prefix NACA-WR-L

There is also a UK R&M report which is a summary of the war time knowledge of cooling system design (sorry don't know the number off the top of my head and my hard copy is buried in the office somewhere) plus aerade.cranfield.ac.uk seems to be down tonight.

Stinton would be another general aerospace design text to check
Don't forget to check the references given in Raymer, Torenbeek, Roskham
