Colleagues:
Hold that Tiger…
I told you a while ago about attending a Massachusetts
“TigerTeam” review of an external store for the F-16. It took
three days of talking about everything else to finally get to the crux:
High thermal gradients in the slab made the cavity unstable! Surprise,
surprise! After the final session I got a tour of the brassboard’s
laboratory. The mechanical engineer confided to me that the brassboard
would not work when it was up-side-down (talk about a tender cavity structure
for a tactical aircraft application).
I’ve also told you about the two day “Tiger Team” in Texas for a
laser, the brassboard of which worked just fine but the flight system lost
power when a laboratory door was opened or closed. In the final session
the mechanical engineers described how the system’s flexure mounts for the
cavity had been replaced (since they were not space-rated) with hex-head bolts!
Then there was the four-day “Tiger
Team” in Illinois that reviewed the flight tests for a two-color recce
system. When I asked to see the imagery they declined and when I pressed
for some quantitative data on the image quality they said they were unable to
measure it. And that was their “improved” design.
And the Culver City “Tiger Team” that couldn’t get their encrypted
light back into their fibers. The optical designer and I both stumbled
onto the fix for that one at the same time.
Well, the Massachusetts folks managed to pull it out and Culver City folks went
into production in Texas. As “Tiger Teaming” goes two out of
four ain’t bad.
…and, here comes 2018. Hold onto your
hats too!!!
