Mig-31 Firefox RCS calculation

As part of an ITPS module on Stealth, I reproduced a Naval Postgraduate School exercise calculating analytically the RCS of the fictitious Mig-31 Firefox. To be more accurate, the RCS is approximated by modelling various aircraft components with simpler shapes which RCS can be analytically calculated.

However, I find that the modelling described in the original document is way over simplifying and highly overestimating the expected Mig-31 RCS. Some modifications were made, especially in the modelling of the engine inlets and exhausts to give more realistic values.  Still, the exercise’s purpose is more to introduce students to some of the RCS concepts, rather than an realistic estimation. Followig the RCS peaks plot at 0 deg elevation angle.

What is your “flying purpose”?

Today I performed a basic evaluation of a Glass Upgrade for DG/HSI and Attitude Instruments on a Cessna 172. It is not a fast jet, but I much enjoyed the process. In the end of the day I feel that what matters most is not “what” you are flying, but “why” you are flying, and for me flying for science and engineering sits in the top of the “flying purpose” list, being surpassed only by flying for the purpose of saving human lives and defending one’s homeland. Cheers

My office this morning

I love my job. Every month is different, every week is different, every day is different! The challenges that come our way are unpredictable, we just improvise, adapt and overcome. This morning my office looked like the image below requiring me to dive into the field of aircraft low observability that I had never seen before. “Γηράσκω αεί διδασκόμενος” (“I grow older, always being taught” also translated as “live and learn”) is a quote by Solon the Athenian, and that is exactly what ‘s happening. It never stops! I am grateful for my job and the people I work with.

Thank you

49th Annual SFTE Symposium, Savannah GA

Another very good SFTE Symposium celebrating the 50th year of the Society. Actually It’s the first one I have been to and not giving a presentation, but was really worth it attending some interesting papers and meeting some colleagues, among them Jon Whitworth, Member #2 and first Vice President of the Society.

Flying a J-3 Cub

Getting some tail-dragger experience at Woodstock Flying Club, flying a classical airplane older than my father! So much fun…
