Eurofighter Typhoon FM Testing
-
Hi all,
I seek some volunteers, presumably with an EF background, to test my new WIP Flight Model for the Typhoon. Anyone who is interested can contact me here or via PM.
Testing should include general handling, maneuvering capabilities at all speeds and altitudes, kinematic performance, altitude performance, acceleration and climb performance tests, endurance and range tests of a clean aircraft.

@Scorpion82
Please count me in, dear mate.With best regards.

Sounds good

@Jackal
NotedBtw has anybody tested AAR with the Typhoon and can report back whether the position basket/probe is correct? Ideally with screenshots if the position doesn’t fit. If so I’ll put it on my to do list.
General remarks, the FM is OFM, not AFM, as I first want to get it right and reasonably close.
I have addressed a number of topics on the fly, such as implementing the emergency arrestor hook (would need some testing apart from the visual implementation).
Weight and fuel loads are accurate now.
Gun location is fixed, matching the new 3D Model.
Chaff/flare dispenser quantity, position and loadout are correct. Two chaff dispenser at ITSPL position and two flare dispensers on inboard flaperon actuator fairings.
Air intake vary cowl movement is now implemented, animation behaviour has been implemented, but needs some validation testing.
General control surface movements and behaviour have been adjusted (airbrake, nozzles, slats, flaperons, roll coupling of foreplanes and “landing flaps” removed).
The general limiter values have been adjusted as part of the overall FM.
As long as no dedicated models of Typhoon racks and pylons are implemented I have assigned those available in the DB and created appropriate rack entries and groups. There are subsequently ITSPL, DMMEL, ALDERU, AHDERU, TEU, MFRL and Brimstone tripple launcher available. MFRL and Brimstone launcher are attached to ALDERU. Due to the lack of a proper 1000 l SFT model the TEU is a separate pylon but goes of with the tank if jettisoned. AAM jettison from FSU doesn’t work yet though and I’m not sure whether the it will be possible to only get the wing pylons and centreline station shown on the SMS page. To be done are dedicated rack entries in the DB to provide tailored weight and drag data for these. Hence no FM testing with stores yet.
Weapon loadouts have been matched with P2Eb and P3Ea standard A/C as operated by GAF and RAF respectively.
I have also adjusted the avionic options to best match the Typhoon within the given constraints. Feedback on that would be welcome as well. This also includes radar data and autopilot envelope.
In the future it’s ofcourse desirable to get everything included in the stock BMS release to permanently improve the simulation of the A/C. I have made an initial package available, we’ll see whether it will find its way into the next update.
Medium to long term a 3D cockpit would certainly be the most valueable addition though. But that needs someone with the will, time, the experience and skills.

Maybe @Manos1981 would be interested to follow that up from a BMS perspective…

@MaxWaldorf
If my advise may count, sure that - thanks for the hint.
Why not TOPOLO too if for this, then?@Scorpion82
AAR with the EFA? With the actual one, do I copy?
I could, but please let me give some time to.
I am upgrading my PC/ system and hope to get it back in two or three days.I will let you know more further.
With best regards.

@Jackal
yes AAR with the EFA. No problem from a timing perspective here.I suppose @MaxWaldorf was talking about the 3D pit here, not about the FM. If there is any interest in making one, I could at least support creating the functional design concept with the in sim callbacks, if it helps. I supported Qawa back in 2008 when he was developing the EF 3D pit for FF5.

@Scorpion82
I can see now. My apologies for misunderstanding, then.Well, to soon with more news - I am trying to test the same, poor my little laptop.
With best regards.

Hello there, Scorpion.
Task accomplished in KTO.
So, you can refuel with an EFA/Typhoon keeping her steady at 315 kts. and a little, let’s assume 2°, right (or left, according to the basked assigned to) from the center position.
“Funny” that she refuels at 5 kts. less than the Tornado does, by the way - more efficient avionics may make miracles, at times. I guess.What’s next?
With best regards.

Update on the general progress:
Beta 1 FM testing is thus far complete and findings are being adressed and progressively tested. Major challenge with the OFM is to tune the supersonic lift values to limit g-authorities. AoA limiters work reasonably well, not perfect though. Idle thrust and fuel flow tables needs to be reworked yet.Vary cowl animations have been tested and refined and are now working satisfactorily. Roll data are now complete as well.
Engine nozzle animation behaviour is now properly implemented and the advanced engine dynamics have been introduced. These are preliminary and need further validation testing and refinement, but work satisfactorily for the moment.
MFD symbology colors have been matched as close as possible to the real aircraft within given constraints. These are part of the FM.dat and can be replaced with the DTC values, if required. Some testing is required to determine whether all changes are acceptable though, given that the symbology is not exactly the same in the F-16.
Other avionic settings have been tailored to best match the Typhoon. Auto throttle control activation is still being investigated as it seems not to be a simple 0 or 1 only switching.
Dedicated racks have been included in Beta 1 already, but related testing is postponed, until FM development of Beta 2 has progressed to a satisfactory level.
For Beta 2 I consider an open test, maybe using JSGVM or another suitable mod manager.

Gents,
I have created a BETA 1.1 for open testing, as BETA Flight Model development takes more time.
The changes, compared to the stock BMS 4.36 Typhoon aircraft are described within the readme file, as are the installation instructions.
NOTE: If your install is modified (database edits) this mod may cause issues. It’s extremely important to backup the files you have, as described in the readme.
Simply extract the zip to a folder of your choice, backup the files of your install, as described within the README. Then extract the install.zip file on your Falcon BMS 4.36 maindirectory. This will extract the files in the appropriate folders and overwrite those already located there.
I haven’t managed to get it working with OvGME in time, so I decided for this simpler solution.
Feel free to test the modified aircraft, its flight model, weapons and avionics settings. If you have any questions, comments or other observations let me know.
If devs of the BMS team or theater feel that this mod is good as is, or wish to include content of it, feel free to do so, giving credit to me. I can support devs, if required to support integration of the modifications, if required.
LINK DELETED
Best regards

@Scorpion82 All updates you shared are already in integration process
-
thanks for the feedback. There is quite a bit more content now and in particular a new flight model, which is work in progress. The present one within the beta is still an interim solution though.
General remark, the installation instructions in the readme still refer to BETA 1, instead BETA 1.1. Nothing changes with regard to the installation or affected files, however, the referenced import files are not included, as it would be a bit more complicated to include the import files, especially those for new record numbers, which aren’t present in the stock install.
-
Thank you!! I will give this one a go as soon as I have time
You should give OpenModManager a go, it is from the same guy who made OvGME
https://github.com/sedenion/OpenModManThe start is a bit complicated in choosing folders with the naming of context menus, but it is more powerful.

@DrJester
thank you for the hint. I may give it a try for a future beta release, if necessary. When the work is considered suitable and is directly incorporated into the stock release (some of the work will be included with the next update on 4.36), we’ll certainly be able to skip this and avoid the dance and any potential compatibility issues. -

I’ve not started to evaluate your new flight model, it will take some time to compute perfo diagram from OFM file (once data are loaded from OFM, it takes around 2-3 hours on my machine), but even after that, it will be difficult to build an argumented assessment as there is no public performance data for the plane.
If one know he can’t comment…

@TOPOLO
Don’t worry, as said the current BETA 1.1 FM is an interim solution anyway. I consider it good to go for the time being and definitely more accurate than the stock FM. I’m working on a more advanced one. Ofcourse it can’t be as accurate as the FM where detailed charts are available.In any case I would be interested in the plots, as it may ease assessment of the FM. I’m currently using an excel spreadsheet. Is the programme you use specifically designed to calculate the aircraft’s performance based on the dat content?

I have deleted the link to the open beta test version of the EFTP. The modded Typhoon is now fully integrated with the OFM Theater which can downloaded from
here.OFM development is now complete with v1.2. I’m now progressing with what I call the hybrid flight model, which attempts the development of an AFM. It might be a bit simplified though, compared to the extant AFMs for other aircraft.

This is good news, mate.
If you would like, please count me in for further testing.With best regards.
