Sorry Fred

Restarted  FSX with HTR & the Bell 206 but she back to the problems I had earlier this week.

Just before take off she turns up side down.

I restarted FSX several times with no change.

Thomas,

Are you starting HTR with the flight sim, or are you waiting to start the 206 with engines running and then turning on HTR??

Personally, I have to wait until the bird is up and running before starting HTR and taking off.  Otherwise I get the same quirk as you.

EDIT:  Also make sure you work your collective and throttle through some motion before starting your bird.

In the next few days (possibly on Sunday) I plan to release a minor update of the software (version 1.02)

If you widh to send me your email adress I can send you a preliminary release of the update and you can send me the debug file so maybe I fix the behaviour for the update itself.


The update will include a few small improvements one of which will be flight recording/replaying and especially for me ...debugging.

It will also be a cool feature as you will be able to send a recorded flight to someone and maybe add a sound file to do virtual lessons ....

Also this will allow me to debug in detail the application and uderstand why sometimes the flight starts with strange behaviour (I think it might be FSX sending strange data upon load and HTR going nuts, if I have a debug file I can most probably fix that).


Bye
Fred

I have continued working on a Cera Bell 412EP profile, and have a newer version available for download.

This one flies and turns much better, and is more stable in the wind.  The autostabilization in the .cfg has been turned down, so if you find it too unstable, edit the .cfg...[increase the figures to around 20-30.]

**Caution**  pay close attention to you VNE, or be prepared to suffer the consequences!!

hello everybody,

I'd like to express my appreciation for this program and for the efforts in making it. I just want to tell you something I have noticed: I normally use the HUD when I fly an helicopter and it is strange to see that the rpm indication is different if taken from the HUD rather from the little window given by your program. I mean that often the HUD gauge says 107% and in the other window you can read "low rotor rpm" toghether with an indication of less htan 100%. Am I mistaking something? Is there an explanation?

Hi all

I don't know if this is a bug or if the problem is on my side but
I cant seem to get a smooth take off with htr.

It appears that there is no torque yaw when you start to
lift the collective on the ground , it seems to come on only once you are in the air, so when im at about 50% torque and
light on the skids there no torque yaw and the helicopter
starts to slide in the direction you push the pedal to counteract torque yaw on take off.

so as i try to straighten the nose by pushing the pedal
in the other direction and pull the collective slowly
to 60% torque it jumps violently into the air and yaws to the side so i can't control yaw during takeoff because it comes on after im in the air.

Ive been able to get a smoother take off by increasing the
max collective entry in the cfg but the problem of no torque yaw
when light on the skids still remains. Also once im flying i can't seem to go beyond 60% torque without getting the low rpm warning.

by the way im mostly using the default 206 dynamics but
the other helicopters also have the same problem.

has anyone else noticed this

Hi,
no this is normal. As explained on the manual I could not alter the rotor RPM value on FSX as an effect of the physics model. I tried in many ways but could never get a result (it is a derived value).

Also I wanted HTR to be working for any helicopter model, and fixing this might have meant creating a specific gauge for each of them...

So I decided to give my own RPM indication in the small window when below or above 100%.. The rotor RPM you see inyour HUD or instruments is from the FSX flight model.

All other flight instruments work as they should, only the rotor and engine rpm have to be overrided. I hope I can find a solution one day...

Bye
Fred

Just passing by to say that your config for the 412 is great. Really great indeed. The only thing I have issue with, is when I am at hover and reduce collective, it starts to descend but when it is near the ground it bounces a bit up, this is probably an over reaction of ground effect.

Regards.

I had to turn off the FSX head movements did you guys turn it off too? It caused little strange head movements, like in the hover your head is all tilted and you lost a bit of visual references.

Regards.

Thanks for the comments Focha....I've put a few hours into that .cfg, so its good to hear people are enyoying it.  I will continue to work on the 412 profile and try to iron out all the details to make it fly realistically.  I know that it bounces too much on the air cushion, but that's the best I can do for now.  There are many other parameters of flight that the profile does not do realistically...for ex. the max hover altitude is way off....it will only fly at lower altitudes right now, - below 7000 ft i think.  

I also had to turn the head movement off...it was totally messing me up!!

Hi,
regarding the 412EP great configuration I agree.

Thanks to Focha I found a bug on the ground effect calculation, I was using the rotor height vs the datum instead of vs the groud and adding the sim helicopter AGL height. This puts the rotor for the 412 EP at 7.5 feet from the ground, also rotor radius affects the ground effect. I  will probably have to add a parameter to fix that.

I am fixing that in the next minor patch (max a few days)

What is this head movement thing ? mine stays where I tell her to... :D .
Just kidding, where do you disable it ?

Bye
Fred

Hi there Fred,

Thanks for the quick reply. About the head movement, in the fsx.cfg file you have a line like this;

Code Sample
[DynamicHeadMovement]
LonAccelOnHeadLon=-0.020000
LonAccelOnHeadPitch=-0.010000
RollAccelOnHeadLat=0.010000
YawAccelOnHeadLat=-0.100000
RollAccelOnHeadRoll=0.100000
MaxHeadAngle=5.000000
MaxHeadOffset=0.300000
HeadMoveTimeConstant=1.000000


I replace the values with this ones;

Code Sample
[DynamicHeadMovement]
LonAccelOnHeadLon=-0.000000
LonAccelOnHeadPitch=-0.000000
RollAccelOnHeadLat=0.000000
YawAccelOnHeadLat=-0.000000
RollAccelOnHeadRoll=0.000000
MaxHeadAngle=0.000000
MaxHeadOffset=0.000000
HeadMoveTimeConstant=1.000000


Don't know if those are the most correct values to input but it works fine with me. I have track ir 4 by the way.

About the ground effect, it's correct to say that the rotor radius (or diameter) affects the ground effect since the greater the rotor disc the more the induced flow volume.

Best regards.

The head movement values are located in the FSX.cfg, which is in the C:\Users\Windows User\AppData\Roaming\Microsoft\FSX location.

I set all the values to 0.

Thanks for the support Fred!!

In a couple days when I have more time to work on my profile, I intend to send you an email with various questions and comments...thanks again for the wonderful program; I'm having a lot of fun creating profiles!

Fred,

I got a chance to fly the 206 tonight with HTR for the first time.

I just wanted to tell you that it is absolutely brilliant work you have done.  

Very exciting, and very engaging.  I almost can not believe some of the things HTR is doing.  It makes me excited, and helps me to realize that there is still so much to learn.

Maybe someday you will let me learn a few things about FSUIPC interactions from you.  I have been using it heavily for about 2 years, and it seems it can do so much more than what I know.

Thank you Jordan,
I would be very happy to give you any FSUIPC knowledge I have even though I have mostly a physics / aerodynamics expertise.

I'd love to me able for example to be able to have the gauges on the helos report HTR rotor and torque data but I am not a gauge expert...

I am currently working on release 1.02 that fixes a few minor bugs, based on the feedback I got here at hovercontrol this includes:
-FSUIPC version check to avoid running with wrong version
- Lateral COG now affects center of gravity displacement
- Tail rotor Hit small error
- FS9 open config not working if the directory was uppercase
- new parameter for rotor height to fix a small ground effect bug
-new parameter for ground yaw friction coefficient to fix the light on skids issue (I was using the linear friction coefficient but it was  very difficult  to adjust for both effects)
- basic recording replaying records the pilot input and model velocities, this should allow to make small HTR tutorials, maybe running a synchronized voice track
- random failures as requested
- multiple application instances will be blocked.


I think I will be ready next weekend, I would like to replace current HTR version instead of adding a new one. Would it be possible to email the file to Chris or yourself and make a file replacement ?

Thank you and bye
Fred

Is it a power problem or a thrust problem ?

in the first case the easiest way is to adjust the
kconstant parameter which is an experimental value based on thrust/power ratio

in the second case you should adjust the maxcollective value of the mainrotor

let me know...
Fred

Ok, Fred, thanks for that.  I hadn't tried adjusting the Kconstant yet, but will play with that value.

Also, I've sent you an email with some comments/questions.

Thanks!!

Hi there all.

I've been flying and testing the 412 profile. While in cruise it seems that the tail rotor has a lot of efficiency. Can someone test it in cruise? Also, correct me if I am wrong, it doesn't seem that the helicopter fuselage tends to turn into the relative wind but if it does probably it is barely notice because of the high tail rotor efficiency in cruise. Well, aerodynamically talking about the tail rotor disc it should be more efficient with some speed since translational lift also occur in tail rotor but the fuselage drag and inertia should also reduce or lower the tail rotor response, correct me if I am wrong.

Sundog in the configuration file you write the VNE = 120 mph, this is not true, the VNE is ~161 mph (140 KIAS) from sea level to 3000'. After that general VNE you have a bunch of them... VNE decrease per pressure altitude, VNE when above 81% torque, VNE when AP engaged, VNE without doors and so on. I am saying this because in cruise when at 120 KIAS the aircraft start to shake a lot.

I hope I am helping.

Regards.

Edit: Also Fred in your config of Bell 206B you have VNE = 120 MPH, this should be 150 MPH (130 KIAS).

Hi,
sundog is fixing the configuration now, we exchanged an email on this problem, it seems there was an excessive rotor torque and a not sufficient stabilizer effect...

regarding the VNE issue, it a typing mistake from me, VNE should be inserted in KIAS and not MPH....I am fixing the manual now

VNE will decrease due to lower air density (so pressure altitude) and increase if you are flying below max gross weight (affects torque). the increase and decrease is not a linear equation but a slightly more complex one.

Open and closed doors are not modeled, I could do it but it will depend on the loaded model.

The shaking of the aircraft is not programmed, it could be either a stuttering problem (easy if you are flying sideways, check your lateral velocity) or a configuration problem...

bye
Fred
