After more than one year of hard work here it is !

HELICOPTER TOTAL REALISM VERSION 1.02

(edited March 22)

Helicopter Total Realism (HTR) is a program that overrides FSX FS9 flight model with a more realistic model.

All the helicopter reactions are calculated using formulas taken from different aerodynamic books. Every helicopter can be configured using a .cfg file similar to the aircraft.cfg but with custom parameters used by the application to model the physics profile.

I have included a full manual with samples on how to create your own configurations.

Data is passed to and from FS using FSUIPC, so it works on FSX and FS9.

You will need the last version of FSIUPC (4.53 or later for FSX 0r 3.93 for FS9) to work.
HTR will not work properly with previous versions and the helicopter will jump all over. You can check the version under the \modules directory of FSX and clicking on properties for the file FSUIPC4.DLL

The included helicopters in this release are
-Bell 206
-Robinson R22
- Agusta Westland EH 101
- Aerospatiale AS 350 Ecureuil

I am currently working on a release for:
- Robinson R44

(I plan to update this list as more releases come out...)

I have also included the excellent Helicopter Flight Training Manual from the Canadian Dept of transportation which in my opinion is the best free manual on helicopter operations.

Please send me your feedbacks

Enjoy :cool:
Fred

Downloaded and manual printed. I'm at Helisim the next 3 days and I will study the manual. Will be interesting to try it on the FSX AS332L2.

Thanks
Dirk

Lucky you Dirk!

Let me know if you need any help with the flight model, BTW thanks for the great work!

Bravo Fred.  

You have obviously worked very hard indeed on this project.  I am very interested to see how successful your work has been, particularly with regard to some of the work being done in advance of x-Plane 10.

If this does indeed allow designers to work with real world numbers and arrive at a realistic flight model, it is a very significant breakthrough in the world of helicopter simulation on desktop platforms.

I can't wait to hear what some of our professional helicopter pilots have to say about this after having flown the supplied profiles.

Ciao,

Rats404

Hi Jordan,
this is how it works. The program calculates the various forces applied to the helicopter at every cycle (update frequency). Each force causes an accelleration on the three axes, it might also cause a torque based on the force application point position in respect of the center of mass. Rotors also cause torques due to the torque applied by the engine.

The forces and relative positions are configured through a config file. I have also included an excel file and a manual to make things easier.

Through the configuration files you can define over 200 parameters that will  in turn define the main forces and their interactions, namely: Main Rotor, Tail Rotor, Drag, Gravity, Stabilizers. It is not that difficult to do, and creating a new configuration with testing should not last more than 2-3 evenings. The rotor modelig part is the most complex. Rotor thrust will depend on induced velocity that will in turn depend on rotor thrust and helicopter attitude and velocities.

Power  management will then define the power requirement, the necessary power will be supplied by the governor (if present). If power is insufficient (available power will change with altitude, especially for piston engines) this will result in a rotor RPM reduction. In descent, your power need will decrease to a point where autorotative power is sufficient to overcome the other forces, so you can operate a full autorotation without engines.

You can also simulate a series of helicopter specific failures and see how you can manage them.

I am not an helicopter pilot, or should I say a "real" helicopter pilot, but just a "virtual" one so I hope real pilots can adjust parameters to make each model fly as the real one (or I can change the program in case they report an unrealistic behaviour, I see this release as a starting point...)

Twin and coaxial rotors are not supported in this release but I will definitely try to model them for the next one.

Thanks to you Jordan, I think you made this happen, I just contributed.

Fred

P.S.: this software is dangerous to your FSX flying habits, maybe you'll see why in a while...

With a new baby in the house, I probably won't get the chance to use it in depth for a while, but I just previewed the operating manual...and as a person that has done some FSUIPC programming (Missions on Demand uses FSUIPC), this is some seriously cool stuff.  I didn't even know you could do some of those things through FSUIPC.

I really look forward to spending some time with it.

Fred, only every once in a while does someone develop something so interesting and foundational as this for the community, and in that regard you already deserve a lot of credit!

How would/does this effect the Dodosim helicopter?

Dodosim is probably already top realism.I don't believe you would need it for that helicopter. Why don't you try it?

Absolutely fantastic. I did a quick test run with the default Jetranger, and WOW! It makes a fantastic difference.

Gonna do some more flying later tonight, with some of the default configs. The manual is also very detailed, which is very appreciated.

I can't wait to see some configs come around for some addons. I'd like to see how the Cera 412 performs with this.

Fantastic job Fred!

I would like to thank you for this.  I could only imagine the hard work you put into this.  Without people like you this community wouldn't be anything clsoe to what it is.  Thanks again.  Now I have to figure out how to make configs because I got a list of them I want with the Kiowa being at the top lol.

I am so glad about so many positive responses, thank you, its very rewarding.

I can give support to anyone creating new configurations, don't hesitate to post here any requests.

Nick, the Kiowa should be a breeze to model, just changing a few parameters from the jetranger, weight, drag and engine power should do. Which FSX model do you use? I can fix that for you.

Fred

Well Done That Man!!!

Right who fancies writting configs for every addon chopper I have by tonight ha ha,

Again, many thanks you have realy given somthing to the community.

Hi,

For this to work properly I take it that it requires the original default .air and .cfg files for the EH101 & JetRanger. I have slighlty modified the EH101 and it is uncontrollable. As soon as I apply any collective it just spins out of control, the same with the JetRanger but I havent changed that one. Also with the AS350 I keep getting Vortex Ring State appear when I am not in the flight conditions for that to happen. But otherwise the 350 doesn't feel too bad.

Any help or advice appreciated!

Rich

EDIT : - Right got that bit sorted - what realism settings are people using with this?

The config for the AS 350 BA can be also good for the Lama and Colibri with a few mods.I dont have time now but will look in to it.If someone cooks up a good one for the Nemeth UH 1H,please post.
Thanks again for this outstanding work.

Hi Rich,
changing the config files should not alter the behaviour, maybe the air files might make a difference, I never tried.

Now a few, maybe silly, questions:
- i guess you are using FSX and not FS9 (EH 101...)
- do you have the last version of FSUIPC ?
- have you tried with a different joystick / calibration ?

Jetranger test
- check the air data window for the percent collective, cyclic and pedals, you should be having respectively 45-50%, 0% 0% on cyclic, 65-80% on pedals, if not something is wrong with FSUIPC or the hardware.

Hope this helps
Fred

I don't intend to use it to better the Dodo, I just wanted to be sure that if I install it, the Dodo won't get messed up.
