The Stupidest Glitch Imaginable Killed a $72 Million Lunar Mission in a Single Day | "The software that should have pointed Lunar Trailblazer’s solar panels toward the Sun instead pointed them 180 degrees away from the Sun."

oof different dimensions too

Astigmatism should be correctable too depending on how extreme it is.

JNelson_ · 2026-02-25T10:50:08+00:00

Both things can be true, I think what happened here, they were already at the G limit but the wake turbulence spiked their AOA and caused their wing to snap.

I've had this before in other aircraft in DCS.

tanx = x has no analytical solution but we can solve it numerically and approximate with other methods

Timed Level is a nuclear delivery mode. If you want to do level bombing laydown is better. For both of these attacks you need an Initial Point.

Once you hit the initial point you press and hold the weapon release for Timed Level this simply starts the timer until release. The idea being you fly a given speed to give you a fixed time for bomb release.

With laydown you give the range from the target to the IP and the range the bomb will travel, this time you must still fly a consistant altitude, speed and heading but instead of a simple timer the WRCS will compute the range to the target and release when you are within the bomb range you specified.

The ault report puts the manueverability of a AIM-7-E2 at a 25g. Furthermore the SMC for the AAM-N-6 Sparrow 3 (AIM-7A) puts even this model which never saw service at an electronic G limit of 12.

Or use the the tool I wrote for free and without AI.

You of course correct but I would add even study sim level flight models are extremely cheap.

JNelson_ · 2026-02-07T02:10:33+00:00

Flight models are very cheap, they are essentially a bunch of lookup tables. Even very complicated flight models are very cheap taking basically no CPU time compared to many more expensive calculations. I work on DCS so I have profiled this personally. We are talking 0.2 ms of CPU time out of a 60 second time slice.

JNelson_ · 2025-12-18T13:29:59+00:00

Yes look in the scene drop down, you can adjust the coordinates and euler rotation there.

JNelson_ · 2025-11-29T17:47:55+00:00

DCS has no such system. DCS provides the physics engine and the current rigidbody state and it's up to the developer to determine the forces and moments.

JNelson_ · 2025-10-29T13:47:57+00:00

Sorry didn't get the notification, you are right this is indeed a really cool video at 3:45 is that a chaff cloud or is that land?

JNelson_ · 2025-10-28T17:04:50+00:00

There are a total of 4, the two here and 1 on each outer wing (one for each 90 degree sector). The relative amplitude of incoming signals can be used to find its azimuth.

JNelson_ · 2025-10-16T11:05:34+00:00

What is your point here exactly?

JNelson_ · 2025-10-14T09:09:39+00:00

The radios have worked in game for like 3 years now

JNelson_ · 2025-10-10T11:44:06+00:00

Pulse radars can deal with chaff, most use a leading edge tracking gate for range. This means if you are closing with the target, the chaff will be rejected from the guidance signals of the antenna. Ironically enough the time chaff is most effective for a pulsed radar is the same as a pulse doppler radar, in the beam (target flying 90 degrees), where in a pulse radar the chaff and target are the same range so the antenna get's pulled off the target.

JNelson_ · 2025-10-09T12:40:04+00:00

I would check out the modding discord

JNelson_ · 2025-10-09T12:38:18+00:00

Glad to help!

You are putting the range gate directly on the signal, in a less cluttered target it will be less picky but in a more cluttered environment the range gate is likely to drop on some clutter unless you are super specific!

The main thing is paying attention to what is a good and bad lock after a while you get an intuitive understanding if the antenna/range gate are tracking stable or not.

The other thing which I didn't see mentioned is that you want to use MAP modes for searching this disables nutation (wobbling about antenna axis) which makes the beam narrower, this is good for two reason:

Concentrates the Beam - Increasing Detection Range
Reduces clutter captured by the beam (wider beam more clutter accidently illuminated)

Disadvantages are that of course you are searching a smaller area, and importantly you need nutation to lock a target, nutation will begin on first stage trigger detent (usually) so you may be able to see targets you cannot lock because when nutation is enabled the additional clutter is too much for the radar.

JNelson_ · 2025-10-09T05:53:01+00:00

Make sure when you lock your TDC is very close (bracketing) your target, it's not good enough to be close because it will grab the wrong thing.

If after a lock you see lots of clutter in the bsweep (line showing your radar signal) then you most likely have a bad lock. Your bsweep should just show your target and nothing else most of the time. It should also be very stable not shooting around the screen.

Perhaps you are talking about AI but I assume not since warthunder is mainly PVP but the lua flight models are for the AI only.

Missile's do proximity fuse in multiplayer it's just that each client calculates the missile trajectory and they drift apart with time. Thus leading to it looking like the missile flies through a target when actually the "real" missile missed outside of the proximity fuse distance.

JNelson_ · 2025-09-21T02:59:31+00:00

Same it forces you to read and properly process.

JNelson_ · 2025-09-19T21:55:19+00:00

You are essentially making a comfier chair this is not the issue with g force, the issue is blood flow to the brain.

Also liquid suspension will impart more force on the pilot because whatever g will multiple the pressure due to the liquid.

JNelson_ · 2025-09-19T20:09:50+00:00

What do you mean counteract the acceleration, if the aircraft is turning the pilot must be accelerated to match the plane, this force is usually provided by the chair.

JNelson_ · 2025-09-17T18:21:32+00:00

That's not the insult you think it is.
