[1.3.1] Ferram Aerospace Research: v0.15.9.1 "Liepmann" 4/2/18

StainX · October 9, 2014

@Anyone having structural failure issues on load: : Without a copy of the output_log.txt and reproduction steps, I can't help you. You will also need to verify that you have a FARAeroStress.cfg in your FAR folder in GameData, and that the CustomFARAeroStress.cfg in the same location dos not have any zeroes in it. If the former, reinstall FAR. If the latter, delete CustomFARAeroStress.cfg.

Excuse me, couldn't find the output.log on linux... quick google told me it is called player.log on there, so...

Player.log

Also i deleted the CustomFARAeroStress.cfg and restarted, but still the same problem with the new file:

CustomFARAeroStress.cfg

let me know if you need some help testing on that

so, dumb question, but uh... is there an archived version for 0.14.1? I looked in the available log that the creator provides, but the newest one that I can find is 13.3... either i'm blind, or it hasn't been logged

Anyone know where I can get 0.14.1.1? I can't find it on the "previous versions" page.

Go to Ferram's github page , it should be on the (linked) releases list

Jovus · October 9, 2014

I have a funny little bug to report that may be already known.

It appears that FAR doesn't properly update the craft's CoL in the SPH with regard to its orientation. The plane nevertheless flies fine; it's just a building issue.

In specific, it seems that instead of recalculating the CoL, it simply rotates/transforms the CoL about some pre-determined reference point, which is problematic for rotations when your plane is not on that axis.

Grr. Unfortunately it appears I don't have images to show for this because my computer crashed hard while I was writing this post the first time.

@Drakoflame & Whovian: Available on KerbalStuff or Github, just look beyond the download button for the older releases in the changelog / releases section.

@Moistmonkey: Aware, confirmed, and looking at fixes. Shouldn't be that bad to fix though, I think I know what's wrong.

@Jovus: Nope, the CoP is constantly being recalculated. That's how it moves when you change the orientation of the vehicle. The result it gives is correct.

Wanderfound · October 9, 2014

@Wanderfound: For the first one, that little bit of red explains it completely. Sideslip increases yawing motion, which is going to result in rolling and pitching tendencies. That sounds about correct.
For the second one, why are you not considering fuel burn after getting up to that velocity? Also, you've got WAY TOO MUCH dihedral on that design, and that is probably contributing to it. A lot.
I will also note that since you're not looking at the AoA Sweep for the static analysis that you actually have no idea what AoAs your plane is stable at. For the Mach 5 case, the Mw is so low that I wouldn't be surprised if it flipped sign the second you got above ~7 degrees.

Ummm...the second design has flat wings. The only dihedral on it at all is about 10Ã‚Â° of upsweep on the wingtip winglets. It's set up to have negligible weight shift from fuel use, and the porpoising starts immediately after takeoff, regardless of AoA.

Jovus · October 9, 2014

@Jovus: Nope, the CoP is constantly being recalculated. That's how it moves when you change the orientation of the vehicle. The result it gives is correct.

First, in the default orientation:
Here's the accompanying analysis:
But if I turn it (with the A key), this is what I get:
What is that CoL doing hanging out off to the left? Maybe it's just a visual issue and it's actually being calculated correctly?
Nope:

Note that the craft flies fine in its intended envelope, as said before. It's all stock parts as well, but

That doesn't seem necessarily wrong - if you try and fly the craft sideways then the the front and back wings aren't necessarily going to behave the same way.

@Wanderfound: I see that I'm going to hate the stock swept wings now, they make figuring out the configuration of the plane from a picture difficult.

Okay, what exactly do you mean by "porpoising"? Is it just changing AoA rapidly? Then you need more pitch damping, add larger horizontal tail / canards. Is it yawing from side to side? Add more vertical tail.

@Jovus: Yes, that is correct. The plane is flying sideways, so its CoP will be in a different position.

NathanKell · October 10, 2014

Wind direction always comes from that open-door end of the SPH, or the roof of the VAB, when in editor when showing CoP.

Jovus · October 10, 2014

OK, thanks guys! Glad to see it's already covered.

I've noticed that the Mk16 parachute gets ripped off now at speeds and altitudes that it readily survived on 0.24. Is this a change to KSP itself, or a difference in how FAR (and/or Deadly Reentry) calculates the forces? As an example, my go-to chute setting was to have it deploy at 0.08 atmospheres and fully deploy at 350m. With 0.25 and the mods I have installed the chute gets ripped off even if I change the initial deployment to 0.25 atmospheres. I know the chutes are still working as I've done some other things that have slowed the capsule down enough to allow the chute to survive deployment, though I haven't nailed down what the critical speed threshold is yet. No complaints, I'm just trying to understand the new performance I'm seeing.

Porpoising: oscillating pitch changes, from about +5 to -5Ã‚Â° AoA, trending down over time. Left to itself, the plane will gradually level and then dive, acting like a rocking horse the whole time.

I'll give larger tailplanes a try.

Wanderfound · October 10, 2014

BTW, it looks like the next thing to add to my FAR design guide (http://forum.kerbalspaceprogram.com/threads/90747-Kerbodyne-SSTO-Division-Omnibus-Thread?p=1353891&viewfull=1#post1353891) is going to be "what to do for each red number in the derivatives screen".

If anybody feels like helping out with that, you'd be more than welcome.

ferram4 · October 10, 2014

@krenshala: FAR has never affected parachute forces at all. Nothing has changed there.

@Wanderfound: Ok, so that sounds like very lightly damped short-period motion, and it's just as dangerous in real craft as you've found. It's one of the many reasons why single lifting surface designs aren't often used unless they're highly swept delta wings with very low AR (which results in slightly better damping from the wing alone).

I'll note that your aero analysis stuff is pretty good, except fro the part about the yellow Cm line on the static analysis graph. The sign of that is less important for stability than the slope; when the line slopes down, the craft is stable. When it slopes up, it's unstable. The absolute magnitude is mostly just an approximate idea of how much pitch control you'll need to keep the thing at a given angle of attack; the plane will stabilize at the AoA where the Cm line crosses 0 (for a downward-sloping line), and the primary effect of increasing / decreasing the pitch deflection is to shift the Cm line up or down, shifting where it crosses the X axis, and so what AoA it will stabilize at.

Thats what I was thinking, but wanted to verify. Thank you.

Wanderfound · October 10, 2014

A bit more experimenting:

I'm finding small planes still easy to do, but larger aircraft much more difficult. The big ones seem to require a lot more engine now, too; designs that would previously run on two or three engines are now taking five or more.

Effect of the heavier wings? Just how much heavier did they get?

ferram4 · October 10, 2014

They gained about an order of magnitude more mass. Some of the much larger configurations are even heavier. Previously, they were equivalent to the mass of ultralight wings at the most realistic, and even then it was a little too light.

DaMichel · October 10, 2014

Aha. I always found it extremely hard to make good designs with Sp+. Now even more so, i think.

I found the weight of the new control surfaces a bit odd. The large one has mass 0.4t. Compare that to the rectangular wing piece which has what, 6 times the surface area, and weights only 0.5t.

Does anyone know how the weight compares to B9 pieces? Are B9 wings lighter or heavier, density wise? Because i found it pretty easy to build stable configurations with B9 and i think the weight of the wings might be an issue here.

You're going to hate this, but I'm already wishing I could trade off a little durability for weight. When I took 'em for a snap test, it took absolutely suicidal flying to do it; they handled 15g aerobatics without a twitch.

Something halfway between original and current would be perfect. I wonder if it's possible to turn strength vs weight into a tweakable?

Do control surfaces include weight for hydraulics?

Wanderfound · October 10, 2014

Should it be possible to get aerodynamic failures on parts inside a cargo bay? I've had a few batteries go bang.

ferram4 · October 10, 2014

@DaMichel: The wing mass is based on the wing area that needs to be supported by that wing's connection; this makes wing roots a lot heavier than wingtips. The default masses of wing parts don't matter anymore.

@Wanderfound: The mass of hydraulics is abstracted away completely for simplicity. Current dev version has a tweakable thing submitted by NathanKell. It also has an attempt at a fix for cargo bay issues.

wingnutspeed · October 10, 2014

i am using b9 version 5.2.4 and 14.2 feram and my control surfaces arent working when i have only b9 without feram control surfaces work fine but when i install feram control surfaces stop working they are just static piece dont move up down

This is happening to me too, if you find the culprit please let me know. I have to get well under 200 m/s to deploy without it ripping off.
