It was one of those things where it was not on the front burner of any of Dryden’s projects so they could say, “Yeah, let’s put a bunch of funding into this idea,” so it really took a lot of my own resourcefulness. After I’d get all my project work done, I’d be spending time working on designs, vetting it with some other engineers, making sure it all looked kosher. It actually took several summers. I’d have co-ops or interns helping me, just so that I could still get my day-to-day work done. But it was definitely worth the effort.
What's great about this system is, you have an airplane now that’s sitting on its gear, and you just roll the system right underneath at the jacking points, like you would an aircraft jack. It’s electrically activated, so I have electric motors driving these actuators that then pick up the vehicle, and while the vehicle is resting on the soft support we’re able to retract the gear, because that’s a critical testing consideration. We need to be in “gear-up,” because that’s how the airplane is most of the time. Then we just inflate the system. It takes all of a half-hour, which before, we had to have meeting after meeting after meeting to coordinate such a hazardous task. It would take a whole day just to get an airplane on the isolators, so it saved a lot of time, and it saved a lot of money in terms of not having anything fall that’s one-of-a-kind.
We've now had three opportunities to use it. We’ve used it on our G3 airplane; we used it on our F-15 airplane; and I just got done using it on the Orion Pad Abort Crew Module.
NTB: That’s the new crew vehicle, right?
Ginn: That’s correct. That’s the new crew vehicle.
NTB: How long did it take you to get this system in place and operational?
Ginn: Once we started cutting metal, it was probably, I guess, about a year-and-a-half to get all the parts and get it assembled. I had to build up manuals for it. I mean, it’s a very formal system. It had its own task analysis; it has its own maintenance book. Then I had to set up the whole proof testing for it. We put 108,000 pounds on the entire system to proof test it. So I designed all the fixturing that it took to do the proof test. As soon as that test was done, within a month, we were actually using it. I actually completed it in December 2005 and it was used for the first time in January 2006.
The whole idea started in 2002, just to give you an idea of how long it took to come up with the money. It’s a system that, throughout the years, has added up to at least $200,000 of materials and off-the-shelf parts, so part of the money resourcefulness was, each year, kind of going around and trying to get people’s end-of-year money, or find little scraps of money or people who were interested in investing in it, and it took a couple of years to build up all the parts we needed.
