We made our XMLs with, horror of horrors, a Visual Basic script that ran in Excel and digested several input documents to generate a map template that we could then tweak by hand and turn into an XML through another VB script.

Oh, thanks for the spot. Not sure why it's doing that...

All of this was done as a work up to a carrier deployment. In software terms, trying the arrestments on land is deploying to test, doing them on a carrier is production. There were three separate developmental test deployments to carriers f

That's what the flight testing was for. I am not aware of a way to all-up test something as dynamic as an arrestment without actually building a jet and trying to catch a wire.

The F-18 tailhook geometry is far different than the F-35 tailhook geometry. F-18 hooks are much farther back from the main landing gear, and are also much longer.

Quarto made that really easy. Very cool.

Yes, there are pendants that are supposed to keep the wire above the deck, but the short space between the F-35C main landing gear and the tail hook point means that there's not enough time for the pendants to raise the wire above the

I am but a grunt who mostly programs radar models, I didn't know Quarto blogs could do that until just now. Yeah, sure, I'll add it.

There was a lot of static load testing done, and things like a drop test [0] of a full scale article. But to my knowledge, the only way to test the dynamics of a carrier arrestment is to actually do an arrestment. We do them on land; NAS Pa

The whole purpose of this series of tests was to try to exercise the arresting gear in the most punishing ways. One way that's usually done is to try to arrest far off the centerline (where the arresting force will be applied far more

Author here. Did not expect to see this on HN at all. Just an engineering war story I shared.

What the other person replying to you said. They even use this terminology in official documents. So I do, too, for laughs.

The missile clearly fuses, it had a warcranium. Where are you and others getting the idea that the missile had no warcranium?
47.
by euler_angles 4y ago
Yeah that missile fused. It was a normal AIM-9X. Missile war cranium detonations are underwhelming (there's not that many pounds of explosives involved) because they are trying to kill aircraft via shrapnel of some kind. Two common des

The problem with being an expert on the F-35 is, you can't talk about most of the things you know. So internet hot takes dominate and you can't refute them without revealing things that you shouldn't reveal.

The F-22 was that advanced. The avionics suite of the F-35 is significantly more advanced than the F-22. The F-22 hasn't been produced in over a decade and is going to be phased out in the early 2030s. Even if there weren't a la

In the present time, there is an air defense network around Washington DC. It uses the NASAMs system. Anything that is determined to be a threat can be engaged with surface launched AIM-120C missiles. https://www.kongsberg.com&#x

You're right about the tone of those statements. But just how much dystopian bureaucracy can one take before expressing displeasure at the dystopian bureaucracy?

There are definitely organizations within the US government developing software that need to be convinced.

Had a great experience with black. Only thing I did was change its default line length limit to 120 characters (I was regularly dealing with signal names from source data that were about 90 chars).
