A day in the life of an Aerospace Engineer

[Cyrus]

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...

or the tail rotor....

X-47 UAV. This UAV is massive. It has a jet engine of an F-16

a lot bigger than the model....

big landing gear

I'll post more later, this takes time.

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 in to 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.

This UAV operates out of the airport I fly at (with a person in it)

Vortex generators on the wing to keep the flow attached.

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.

[FredGarvin]

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?

[FredGarvin]

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.

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.

[Cyrus]

Attending an Aerospace & Defense Testing conference in the Baltimore convention center this coming weekend. Will post pictures and description of what goes on there: our aircraft will be on static display.
