The J-20 exists in significant numbers, as well. The SU-57 really doesn't.

The default for an F-35 is to be at something like M=0.9 and altitudes of 20-25kft.

I didn't work on this effort, I am just in the same circles with a lot of people who did and still do.

Those are not really F-35 equivalents; they aimed for different points in the design space. Both Russia and China cannot match the US on very low observable technologies, so they have tried to make the most low observable platform they coul

It's mostly a certification issue. There are some hardware changes and integration work that has to be done, but the biggest obstacle is that the certification work is done in and by the US. So there's a diplomatic element.

The Gripen is not a dual-capable aircraft, meaning it isn't certified to carry nuclear weapons. This makes it a tough sell to NATO nations who must align themselves to NATO's strategic goals [0], which call for nations to contribu

I've worked with quite a few people who were part of the AI effort, and my current boss was the architect for ACE a few years ago. All of those people were painfully aware of the gap you describe here and were actively working to bridg

But it did the most extensive flight test program for anything in history [0]. I worked on this program for years. I do not think a lack of flight testing is the problem. The problems are many, but in short: 1) Lack of competent, forceful

DARPA's Air Combat Evolution program (ACE) began with AIs fighting each other in a simulated environment in a tournament. Then the winning AI fought against a human (USAF Fighter Weapons School graduate) in that simulated environment,

By the time the signal reaches your GPS receiver, it is below the thermal noise floor of even amazing receivers. But each GPS satellite has a unique pseudo-random code (called a PRN) that is within the signal. Receivers that listen long eno

I have crossed paths with a lot of bad code. They write it faster than I can fix it.

The regime of steadily decreasing F-35 prices as new lots are contracted is at an end [0]. With inflation and the cost-overruns on the Tech Refresh 3 upgrade package, we are in a regime where prices will slowly increase. [0] https:/&#

They all came out of a book that anyone can buy called "F-35: From Concept to Cockpit". That book is a compilation of papers presented at an AIAA conference in 2018.

The F-35 contract was awarded on October 26, 2001. I was in my freshman year of undergrad, 18 years old. I started on the program in August, 2010. I was 26 years old. The program has just completed its Initial Operational Test & Evaluat

My own engineering war stories are just that, stories. Any technical information I gave was taken from released sources only. I am extremely conscious of this

Minor correction, the wire dynamics model was provided by Naval Air Systems Command (NAVAIR), the Navy engineering organization in control of research, development, test, evaluation, and sustainment of Navy aircraft.

I went from doing things like I describe in the blog post, to verifying and validating the most complex electronic warfare simulation the DOD has ever done, to being a developer of one of the enabling technologies of that simulation. I beli

Yes, the tailhook bay is very, very small. We had a primary disconnect in the bay for the instrumentation wiring for our tailhook sensors. Any time we had to get at that disconnect without having the tailhook trestle removed, we would call

I have not forgotten your user name here, ha. Yep, been a minute. I should hit you up via email.

As a guy who knows the F-35 and the program pretty well, I think the best Canadian minds on the F-35 are Richard Shimooka with the Macdonald-Laurier Institute, and former CAF and F-35 test pilot Billie Flynn. Shimooka has a number of works

The CH-46 has been out of US Navy service for 20 years and Marine Corps service for almost 10, just as a program note.

I abhor war. I believe the only way to secure peace is to be very good at war. That's why I participated in flight testing the F-35, and why I work on electronic warfare simulations now. I wish I lived in a world where there's no

For F-35 flight test specifically, nothing comes to mind. Perhaps I'm a victim of the forgetting you mention.

There isn't a similar carrier aircraft in the inventory that could have been used, as far as I know.

by euler_angles 3y ago
Absolutely. We had a whole carrier suitability team full of people who lived and breathed this stuff. It was just my responsibility to make sure the aircraft instrumentation system got them the data they needed, at a high enough quality, to

by euler_angles 3y ago
No offense taken. The observation of an instrumentation technician and an engineer (me) definitely counted for not much at all in the grand scheme of things. And we could have just as easily been proven wrong.

We weren’t allowed to have any other real programming tools, and the telemetry “maps” we were trying to make were/are major/minor frame oriented. This maps nicely to a grid of data: a spreadsheet. IRIG 106, Chapter 4 PCM telemetry

Yeah, dynamics will be different, though caveat I am not a structures/loads engineer. I just don’t think anyone had the risk appetite to chance a test asset against a very difficult to achieve test point.
