krashkart Posted January 19, 2014 Share Posted January 19, 2014 when i try to open parachute calculator it says it isn't a proper win32 application :/cziken20, this might help you out in the meantime:Straight up, the equation is this:d = √(8 * m * g / (Pi * v² * Cd * 1.223 * p * c))where:d is the diameter each parachute you will use will need to be (m)m is the total mass of your craft (kg)g is the gravitational acceleration of the planet (m/s²)v² is your wanted landing speed squared (m/s)Cd is the drag coefficient of the material you are usingp is atmospheric pressure where you are landing (atm)c is the number of chutes you will be usingSo for example, landing a 4.5t mk1-2 pod with a parachute at 6m/s on Kerbin with three nylon parachutes would give this:d = √(8 * 4500 * 9.81 / (Pi * 6² * 1 * 1.223 * 1 * 3)) ~ 29.1m That would mean each parachute would have a diameter of about 30m Quote Link to comment Share on other sites More sharing options...

OMGNot really, the material only defines proprieties. You'll be able to do what you currently do with tweakables, but with more flexibility, and with functions of the current calculator.

ImThat1Guy Posted January 21, 2014 Share Posted January 21, 2014 Is there any way to cut chutes as part of staging? I'm trying to make a versatile lander for all the atmospheric bodies, but since they each have different atmospheres, neither pressure nor altitude ends up being a good indicator for when to cut and decouple my drogues. I suppose I could do action groups, but staging would be vastly more convenient (because when I cut the chutes, I also decouple the heatshield that they are attached to).Hopefully I didn't accidentally double post; I wrote something similar and tried to submit it without being logged in, but even after logging in it hasn't shown up.

Tw1 Posted January 22, 2014 Share Posted January 22, 2014 Quick question: will this effect parachutes on craft launched before adding this mod, or would I need to do some save file editing? Quote Link to comment Share on other sites More sharing options...

It's on and off for a single part, and isn't related to modules. Action groups and part right click will have to do I'm afraid.Quick question: will this effect parachutes on craft launched before adding this mod, or would I need to do some save file editing?Given it is a PartModule, it will only effect new crafts, but that's not a big concern given that this is something that is only ever used in the editor Quote Link to comment Share on other sites More sharing options...
Mokmo Posted January 23, 2014 Share Posted January 23, 2014 I'll just put this little story here: I had to remove the stock radial ModuleManager configs when i tried to land a probe on Duna that had the Stock radial parachutes installed before Realchutes. The deployment delay was a bit too slow for it. Quote Link to comment Share on other sites More sharing options...
Oinker Posted January 25, 2014 Share Posted January 25, 2014 Can we get the RealChute Drag Calculator as an in-game tool like Kerbal build engineer that's available in the VAB and can be enabled/disabled with a common toolbar icon (like kerbal engineer redux and RCS build assistant)?

Or raise deployment altitude?Can we get the RealChute Drag Calculator as an in-game tool like Kerbal build engineer that's available in the VAB and can be enabled/disabled with a common toolbar icon (like kerbal engineer redux and RCS build assistant)?...

acc Posted January 25, 2014 Share Posted January 25, 2014 what do i wrong when my drag chute does not open when my shuttle landed on the runway?it tells me "waiting for -0.1m/s vertical speed". ahm, negative vertical speed? maybe i can retract the landing gear to get a litle bit, but seems retracting gear while on ground is a bad idea Quote Link to comment Share on other sites More sharing options...
stupid_chris Posted January 25, 2014 Author Share Posted January 25, 2014 The plugin checks if vertical speed is lower or equal to 0. On a shuttle or plane, you do not want to use the must go down feature. Quote Link to comment Share on other sites More sharing options...

Jdav232 Posted January 27, 2014 Share Posted January 27, 2014 Hey, has anyone had a bug where the vessel weight keeps increasing when a RealChute part is strapped on? I am using Mechjeb, and that is where I am seeing the vessel weight. Quote Link to comment Share on other sites More sharing options...

Download the latest version and your craft will go on a diet and stop gaining weight. Quote Link to comment Share on other sites More sharing options...
rpayne88 Posted January 27, 2014 Share Posted January 27, 2014 Sorry if this has already been posted. Also sorry I didn't get any screen shots.While landing my shuttle, which land vertically under parachutes, it broke apart. To be more specific, the shuttle began to spin about its lateral axis. It made 2-3 full rotations before break up, This not only ripped it apart, but it shot the capsule off at 500+ m/s. This after it was coming down at 8 m/s. Other than this bug, the mission was successful. Quote Link to comment Share on other sites More sharing options...

Duxwing Posted January 31, 2014 Share Posted January 31, 2014 You could without reducing functionality have five parachute models--1.25m cone, .625m cone, 1.25 stack, .625m stack, and radial--and make tweakable whether they are double chute, main, drogue, or drag, reducing memory load and increasing elegance.-Duxwing Quote Link to comment Share on other sites More sharing options...

illectro Posted February 1, 2014 Share Posted February 1, 2014 Is there some way to fix the unresearched items in my tech tree that realchute introduces, I end up with duplicated items that are greyed out, and I can go to the R&D lab, research them but they still remain unreserched in the VAB.If there's an easy fix it should probably be in the FAQ at the start.

Is it possible that you maybe made something wrong during installation? Quote Link to comment Share on other sites More sharing options...
