Yes indeed, but I don't see a problem there, the important thing is to have the correct wind loading.

Re: Glider Polar Data
Hi all,
first of all many many thanks to MPT for providing the polar data... However, I use LK8000 and it can't seem to deal with the .xcp files, it wants .plr formatted like the winpilot files. Is there any chance this excellent set of data may be provided in winpilot format?
Many thanks in advance,
Kai.

Re: Glider Polar Data
The .plr format looks quite simple, I guess it wouldn't be too difficult to write the same data in that format
I'll take a look a that next week

Re: Glider Polar Data
Hi again,
you're right, both formats are trivial, so I wrote a quick shell script to translate. It only translates some of the info, obviously it could easily be adapted to include the other stuff as well (glider type, flap settings etc), at the very least as some sort of comment...
Please, if anyone has any experience with awk, feel free to improve on my (doubtlessly mindless) hack. For instance, I tried doing it all in one awk call but it doesn't work, reordering the records is something I failed at miserably... It would probably also be possible to do this as an excel macro...
Many thanks again for providing the polars!
Cheers,
Kai.

Code: Select all
#!/bin/bash
for file in $*
do
echo "Processing ${file%.*} file..."
awk '{FS="="} /PolarDryMass/ {gsub(/"/,"",$2); printf"%.0f,",$2}' $file > ${file%.*}.plr
awk '{FS="="} /MaxBallast/ {gsub(/"/,"",$2); printf"%.0f,",$2}' $file >> ${file%.*}.plr
awk '{FS="="} /PolarInformation/ {gsub(/"/,""); print$2}' $file | awk '{FS=","} {printf("%.2f,%.2f,%.2f,%.2f,%2f,%.2f",$1,$2,$3,$4,$5,$6)}' >> ${file%.*}.plr
awk '{FS="="} /WingArea/ {gsub(/"/,"",$2); printf",%.2f\n",$2}' $file >> ${file%.*}.plr
done
Many thanks again for providing the polars!
Cheers,
Kai.
Re: Glider Polar Data
Don't bother about awk or Excel, it's quite easy for me to generate directly plr files for all gliders.
But only at the end of the coming week.

Re: Glider Polar Data
It wasn't actually completely straightforward (but still quite easy) because the plr format has only one field for the dry mass, which means that the polar velocities have to be recomputed according to wing loading for fixed ballast versions (and BTW that rules out simple awk solutions)
For the time being I have only added the minimal LK8000 extension, i.e. wing surface area.
Flaps settings could also be added as I have the data already available for CoTASA.
Please let me know if someone in interested in that.
A beta version of all files is available there : https://drive.google.com/open?id=12xokJ ... 84sv2N0KYi
Could someone please check if these files are correct and usable with LK8000
If they are OK they will be added to the polar files archive on my site (and created whenever new gliders are released)

Re: Glider Polar Data
Following the release of Hangar Update 10, I have updated the polar set, it is available for download : http://condorutill.pagesperso-orange.fr/
The set is complete with all the previous polars.
The validation procedure has been made more homogeneous (see README.txt)
Validation plots are now available for each glider
Some of the polars have been slightly improved
.plr files are also available for all gliders

Re: Glider Polar Data
Following the release of Hangar Update 11, I have updated the polar set, it is available for download : http://condorutill.pagesperso-orange.fr/
The optimisation procedure has been made automatic (before that it was trial and error by hand)
The accuracy of most of the polars has been slightly improved (if they haven't been modified since HU10)
The set is complete. As the all polars have been recomputed, it is recommended to update them all.

If you already have installed HU11, you may only extract the ASW19 files, but it's probably more work than unzipping everything

Re: Glider Polar Data
Hello!
Thank you for update!
Discus2a.xcp
MaxBallast="208"
DumpTime="208"
It is actually 203 in C2. Can we just change this manually? Or it is needed for some calculations etc
(BTW: 208 is at description)

Re: Glider Polar Data
Max ballast is indeed 208 kg (see data on 3D view), but a 80 kg pilot cannot fill it up completely without going above MTOW
No need to change it

Re: Glider Polar Data
Someone contacted me because the .plr files were incorrectly written.
The bug is fixed, if you need .plr files (see below) download again XCSoarPolarsHU12.zip
Sorry for the inconvenience
BTW these (buggy) files had been on my website since 25/11/2019 (that's almost 4 months) and the bug is found only today

Following the release of Hangar Update 14, I have updated the polar set, it is available for download : http://condorutill.pagesperso-orange.fr/
The set is complete. It is recommended to update all the files because most of the polars have been slightly modified (especially at high speed) when correcting the "Netto bug".

Re: Glider Polar Data
Great work as always MPT, thank you.
You’ve probably already guessed what I’m going to ask...
Could you please produce an up to date comparison plot?
Thanks
