Features

 

  • Shape-Based, Vessel-Centered, Aerodynamics - Long, thin shapes drag less than wide, flat shapes, and smooth changes in body width reduce drag. The shape of the vessel as a whole, not individual parts, controls drag, so shape the vessel as you see fit.
  • Emergent Fairings and Cargo Bays - The voxel model method FAR uses allows for the actual shape of the vehicle to play a role in how lift and drag are applied. Build a hollow shell, and close it up, and everything inside it will be protected from the airflow as it should.
  • Wing Effects - Realistically adjusts lift based on wing position and configuration: wingtips lift less and drag more than wing roots.
  • Stall - Passing the critical angle of attack suddenly reduces lift and greatly increases drag. Can put planes into tailspins, flat spins, and cause crashes.
  • Mach Effects and Area Ruling - Lift and drag will vary as expected with Mach number. Supersonic planes will need to properly area rule themselves for optimum flight characteristics.
  • Body lift - All parts lift: a fast enough brick will fly, if not that well.

Introduction of ModularFlightIntegrator for interfacing with KSP drag / heating systems without interference with other mods

Replaced previous part-based drag model with new vessel-centered, voxel-powered model:
* Generates voxel model of vehicle using part meshes, accounting for part clipping
* Drag is calculated for vehicle as a whole, rather than linear combination of parts
* Payload fairings and cargo bays are emergent from code and do not require special treatment with configs
* Area ruling of vehicles is accounted for; unsmooth area distributions will result in very high drag at and above Mach 1
* Body lift accounts for vehicle shape in determining potential and viscous flow contributions
* Areas exposed to outside used for stock heating calculations

Performance optimizations in legacy wing model
Jet engine windmilling drag accounted for at intakes

Editor GUI improvements including:
* Greater clarity in AoA / Mach sweep tab
* Stability deriv GUI math modified for improved accuracy
* Stability deriv simulation tweaked to fix some minor issues in displaying and calculating response
* Addition of a Transonic Design tab that displays cross-section distribution and drag at Mach 1 for area ruling purposes

FAQ - Common Questions and Solutions to Common Problems

What does this mod do that stock KSP doesn't?

Stock KSP calculates drag as a linear combination of the drag properties of a vehicle's parts, with some interaction changes to handle some of the most obvious aerodynamic interaction effects. FAR instead calculates the drag from the vessel shape as a whole, resulting in a more realistic model of aerodynamic drag and body lift. In addition, FAR accounts for wing shape, rather than just overall area like stock KSP. Finally, thanks to the overall vessel model, FAR can account for things like area ruling, where the vehicle's area cross-section must vary properly in order to fly at supersonic speeds (well, without MOAR BOOSTERS, in any case).

I don't like my rocket coming apart under heavy aerodynamic loads; how can I turn it off?

In the Space Center scene FAR has a debug menu that can be accessed to mess with a large number of the parameters. Under the "cheats" section of the first tab there is an option to disable aerodynamic failure.

Does this plugin work properly with other mods / part packs?

Sure; FAR figures out what the properties of the part should be based on its dimensions and some basic aerodynamic assumptions. If you use a mod and suspect that it causes unrealistic behavior, search the thread to see if it has been brought up / addressed by the latest release; if it hasn't, feel free to bring it to my attention. The only exception is with wing parts, which are more complicated and currently must have their properties specified manually.

Does this plugin make payload fairings and cargo bays work properly?

Yes, it will support any and all fairings and cargo bays. Even those that you make out of completely unrelated parts, so long as you close up the shape. In fact, to FAR, there is little difference between the inside of a closed fairing and the inside of a fuel tank part; they're both just as internal to it.

I can't seem to turn off the Flight Assistance Systems... what's going on?

In the Flight Assistance GUI every button that is pressed activates a control system; when none are pushed down no control systems are active. I suspect that you've actually created a poorly designed craft and that you're attributing aerodynamic forces that you're not used to dealing with to non-existent control inputs.

Do I need ModuleManager and/or ModularFlightIntegrator?

Yes; they are used to properly apply aerodynamic properties to stock wing parts and to interface properly with the game's physics system. Not using them will cause FAR to not function.

I'm using the win64 KSP build and I am still too outraged to read the topic title or changelog, please mock me.

Very well, I shall.  Haha, silly person.  Anyway, win64 is now unlocked for the foreseeable future.  If it turns back into the crashtastic support-heavy nightmare it was, the lock may return, but I do not anticipate the need to do that.

@dkavolis, do you have intentions of making a 1.4 recompile as well? Or just 1.5 up? Just curious. 

I have the 1.4.3 and 1.4.5 unofficial release, but that is without the bugfixes this version has. A backport is easy to make as long as no major KSP updates break stuff though.

I'd rather support a single KSP version for now (and the version RO targets if it is updated). I can provide recompiles (bug free not guaranteed, you would be on your own) for older versions as well, using a script to automate builds for each. You can find 1.4.5 recompile on https://drive.google.com/drive/folders/1_xlZyOvcSAIqgLkbdCPJir_3cLVIsv6V?usp=sharing

Quite likely it will be 1.4.x, unless all the other dependencies are 1.5 ready too. Anyway, thank you for continuing this wonderful mod!

No problem, just want RO to be updated to the latest KSP version.

The fork is now on CKAN, you need to set CKAN to install mods for KSP 1.4 to satisfy the ModularFlightIntegrator dependency.

Just fyi. I just saw this pop up on ckan. This mod requires MFI to function afaik but isnt a listed dependency on ckan

 

Oops just saw the post few above. I have 1.4.x versions checked in ckan. But mfi still doesnt pop up as a dependency.

MFI has been updated to KSP 1.5 on CKAN so it should work now.

@dkavolis: Thank you. I had been building my own since 1.3, but this saves me the effort (and makes many others happy too).

Quite likely it will be 1.4.x, unless all the other dependencies are 1.5 ready too. Anyway, thank you for continuing this wonderful mod!

There is some "KSP 1.5.1" activity happening on the RO GitHub.

FAR disables itself when it is not on a version it has been compiled for, this version is for KSP 1.5.x only. If you can live without the bugfixes you can use my patch for 1.4.x, otherwise you'll have to wait for this version to be backported.

KSP: 1.5.1 64bit

Problem: Lift indicator stuck on ground

Mods installed:

FAR 0.15.9.5

ModuleManager 3.1.0

Reproduction steps:

Copied the master zip file from the github link, extracted the GameData folder from the zip file. Copied the GameData folder and overwrote the one in the main game install folder.

Loaded up a stock craft and toggled the lift indicator

Log:

Read the github files again, very carefully this time. Turns out I also needed MFI.  :blush:

"Speaking of FAR... It's not currently compatible, but I would like to add that. The challenge is multithreading the FAR calculations. I scratched together enough open-source info on the stock aero stuff to make a threadsafe aero calculator, but FAR's methods are not threadsafe. So I could add it now, but it would take a few minutes to generate a flight envelope (instead of a few seconds). I'm hoping to work with the FAR devs to find a way forward....Until/unless FAR makes improvements to their API that lets me access the data I need (or I recreate their methods inside of this mod, which introduces maintainability, versioning, and potentially licensing issues), FAR unfortunately can't be compatible with this. I would really like to make them work, though.

@dkavolis  might the above be within your scope of interest & time capacity to evaluate if it is even a possibility for the future of FAR...a Kerbal Wind Tunnel type envelope plot working with FAR in RO?  Maybe you have already discussed with @Booots  (I did not see any conversation on the topic with Booots over at Git so decided to ask here)  Thanks!

It is definitely in my scope of interest, IMO it should be built into FAR, however making FAR compatible with Kerbal Wind Tunnel should be easier and faster. I'll look into what can be done. Thanks.

RO shouldn't be a problem from a Kerbal Wind Tunnel perspective. Though I haven't tested it, it pulls all the atmospheric and gravity data from the celestial bodies loaded in-game so that should be okay. FAR compatibility is on the horizon for KWT.

I tried the latest repo from 2 hours ago - with Procedural Fairings.

No chance. I even set the start of the gravity turn (MechJeb) at 12 km / 300 m/s.

Too much of a drag from the top. And the fairing is not too blunt.

It's like the whole rocket is "too light" ...
