A day in the life of an Aerospace Engineer

In summary, the conversation is about a thread or blog discussing the speaker's day-to-day activities in the aerospace industry. The speaker attended the AUVSI convention and will be attending a CFD training session in California. The photos from the convention show various UAVs, including a fire scout UAV, X-47 UAV, and a prototype by BAE. The speaker also discusses man-rated engines, fan containment tests, and turbine blade containment. They also mention a piccolo tube for anti-ice protection and a recent visit to Capitol Hill to discuss UAVs with industry professionals and congress members.

A thread\blog of some aerospace stuff I get to do on a day to day basis.

These photos are from the AUVSI convention I went to last week. I will be attending a CFD training session\conference in early September out in California. I'll post and pictures from that if I take any, though I doubt it considering it's more of a technical session. I'll see about posting videos later (maybe). This event was closed to the public, so enjoy:

Fire scout UAV. It's a converted Schweizer 333 helicopter. They have already done a few ship board landings with it, which is quite impressive.

(You can tell my background is in rotorcraft. Only we would take pictures of the hub...

This is a landing grid used for ship board landing. A hook is lowered from the vehicle and caught onto the grid. Then the line is reeled into secure the aircraft to the deck of the ship. Currently, only NATO ships have this grid installed. The US fleet will need to have these retrofitted.

White props are typically made out of wood. This one is made in Germany. The wood has lower polar moments of inertia and reduces vibration. Also, because it's wood, it has infinite fatigue life.

This UAV is a prototype by BAE. Its currently being designed in England. The two turboshaft engines come from (I think) Rolls Royce and are on the Sikorski S76 helicopter.

The front. Though it looks like room for a cockpit, it's not. The hoops to certify the aircraft for manned flight means it will always be unmanned. This is typical for many UAVs.

Nice pictures! I hope to be an AE someday.

Nice pics; very interesting. Our company has made a couple of man-rated engines back in the day, and what our old-timers say, it was a major PITA.
 
  • #5
Apparently you AE's go to airshows all day :tongue2:

Man rated engines are a pain. However, they make the day interesting. Plus, I get to do some really cool tests because of them that you don't usually do for qualification programs.

Turbine blade containment anyone?
 
  • #7
That's not the half of it. All of the testing for man rated engines is tough. From a design standpoint, I think some of the toughest are the LCF and HCF requirements for lifing a turbine rotor.

Fan containment tests are by far my favorite. It's not often you get to see an entire engine eat itself.

I wanted to send you a PM about which company you work for, but I said you don't take PMs.

Piccolo Anti Ice

I was attending a webinar conference call today on CFD. One of the interesting topics discussed was on what is known as a piccolo tube. It essentially ports hot exhuast gasses from the engine to the interior of the leading edge of the wing for anti-ice protection. Really interesting, and new, concept to me. I found a .pdf about it, which is somewhat interesting and gives some detail about this aircraft system.

Today I went down to capital hill to talk with people in industry and congress on the UAVs. It was an interesting discussion on how the FAA needs to change its policy regarding their treatment of UAVs and open up US airspace to allow for the expansion and growth of this high tech industry which has mature, fielded, technology.

I also happened to see Barney Frank in the cafeteria drinking coffee and (I think) Alberto gonzales walked by me in the hallway.

My friend and I talked with a representative of Elijah Cummings, (D) MD. It was interesting because a "Long" meeting with a congressperson is considered 15 mins.

Reminds me of a P-3 flight my father had in 1972 where the engine's dining behavior was a little messy. Shredded rotors cut through the pax area. Fortunately, no one was injured.

http://en.wikipedia.org/wiki/Predator_C" [Broken]! I'm surprised it can carry the Paveway and the JDAM, given their weights. If it's that radically more capable than the original Predator, why not give it a new name? Are they running out of names? How about the Dodo? (Direct Objective Destruction (somethingorother)) LoL!

Interesting: "DARPA also wants the vehicle to use commonly available military fuels, including AVGAS and MOGAS."

Is DARPA aware that just about every US Army and US Air Force land and air vehicle, burns JP-8?

I don't know what the Army ships burn. Anyone? Anyone? Bueller?

So what do you think would be a good use for a UAV other than military? As you said, the technology is mature, and if technology follows the same path it always has, we should be seeing civilian applications very very very soon. But what are they?

Law enforcement and search/rescue come to mind.

The use of a UAV is to gather Intelligence, Surveillance and Reconnaissance (ISR) information. Not really something every day people can use; however, the flight control algorithms used to fly them are. They can pave the way (pun intended) for a 'highway in the sky' type network in the National Air System (NAS).

Can the UAV's and UCAV's perform evasive maneuvers if taking small arms fire? (specifically the helo's when they do eventually go into action) Is there any way to tell if they are taking fire from the operators station?

You mean the interfacing systems to control the UAV remotely? I find that very interesting. I don't have any experience with that, but I imagine it's an orchestra of algorithms that have been written just to interpret and translate human inputs into actions the UAV can actually perform intuitively. I want to see that technology reach more and more specialized consumer products, or at the very least in tooling equipment, and in the transportation industry.

Those UAVs are nifffty. I want to have one, dismantle it, and play with the parts.

One of the highlights of the year, engineering family day. If you have the opportunity to expose kids to engineering, do so. This was my third year volunteering.
