I have now over the last 14 days worked to get auto throttle to work.

So far, the A / T motor is only controlled by two relays (UP/DOWN), signals is taken from two outputs from the  Open coccpit Master card. However, I have big problems with electrical noise, and I probably have to manage the motor with electronics.
 
 
 
Next motorized functions are:
Long trim indicator
Auto Spoiler

WOW, that's absolutely cool !! Thumbs-up

I should receive my new throttle in maybe 2-3 weeks from now. Would be great if you can extend your fantastic throttle documentation by then. Did you now use the original motors or what motors did you use ?

Hi

Yes i will extend my "throttle builder manual"

And no, I have to replace the motor whit an 24v DC compatible motor,

Long trim is now motorized.

More information will follow later.

 

Anyone here who has a solution to set an output, when the main wheels spin up. Must be used for auto spoiler. Can not get "airborne" FSUIPC offset to work.

Hi Claus,

Fantastic !!! Thumbs-upThumbs-upThumbs-upThumbs-up

I will actually get my new throttle from Zuerich airport today. Will start looking at it this weekend.

Is the trimm indicator syncronized with maddog ?

Long trim indicator, auto spioler and auto throttle is synchronized with the Maddog.

However, I have a problem with A/T, when it is active the A/T has first priority and you can move the throttle lever back and forth without affecting the engines.

I have tryet to solved the problem as follows: If the difference between throttle handles in the virtual cockpit and my physical throttle lever becomes too big, then the auto throttle disengage. It works but is not 100% realistic. Maybe I'll find the right solution later.

Incidentally has one pilot told me that in the reality, the pilots helping the throttle levers into place under engaged A/T otherwise, the motors runs up and down in rpm, and that gives a little uncomfortable flight.

So now comes the work of creating documentation of redevelopment.

I had to move my analog inputs from BU0836X and over to Open Cockpit USB card in order to distinguish and manage inputs into FSUIPC.

So throttle is in the house... I got it yesterday from the airport but it was too heavy for me to drag it upstairs to my appartment. Today a friend helped me getting the thing up.

It appeares to be in a slight different condition than yours. I don't have the autothrottle motor. Only the cain is left there... Do I see it right that there is only one motor for both thrustlevelers ?

But I have some other parts still connected to the thrust levers that you don't have. On the part you sawed away. Looks like I can mount a potty right on there. So I think I don't need to build the gearbeld around the big wheels. Sould make things a little easier...

Otherweise mine seames to be pritty much the same as your's thought.

Pics will follow.

 

Cheers,

"I had to move my analog inputs from BU0836X and over to Open Cockpit USB card in order to distinguish and manage inputs into FSUIPC."

Are you shure that you could'nt use the axis assignments in fsuipc ? you can assign to offsets there too or use a lua script for logics.

Hi

The problem for me was that I had trouble separating axis input and output signal from the virtual cockpit, which should drive my motors in the throttle.

So I took the decision to mount axis on the open cockpit analog inputs, then I had no limitations in programming electric motors and the conditions for this in IOCPServer script. Incidentally, all my motors controlled by relays, which means that an electric motor using only one output for  + and only one  output for -

Hi Klaus,

i read you manual on how to motorize autothrottle...but you dont specify which DC motor must buy.

I find one site that seel DCmotor: http://www.servocity.com/html/motors___accessories.html

are you able to suggest me which DCmotor i must buy?

 

thanks,

Simone

Thanks Klaus,
Since I do not have engines below, I have to let me complete the whole mechanism, I must be sure to buy the correct DCmotor model.


After, is easy to install? which software must be used? SIOC?

 

thanks,

Simone

I use motors called PAPST BCI 6325 931 6325 040, with the following data:

40 Volts DC / 0.14 Newton meters / 3150 RPM 1/min.

I do not use 40 volts but only 24 volts, therefore the electric motor will produce this:

0,084 Nm / RPM 1890 1/min.

For the spoiler I'll make an ratio at 1:2 so the shaft in the original electrical motor will run 3820 RPM 1/min, After that its connected to the original gearbox, which I do not know the ratio of. In this setup I belive tha the motor run near the 100% torque, so a more powerfull motor could be used.

The same motor is used to throttle but with a planetary gear mounted with an ratio 8:1 herefore the electric motor will produce this:

0,67 Nm / RPM 470 1/min.

The motor its connected to the original gearbox, in I do not know the ratio. Here is no trouble whit the motor torque.

As you can see i use new and also the original motors and gears for my setup.

I belive that you dont have the original electric motors, on the thottle, so you maybe have to figure out the speed for spoiler and throttle, and the calculate the speed and ratio for your new gear and motors.

I use the SIOC and open cockpit master card to control the motorcontroller, but i think the open cockpit motor drive is a better choice.

 

I hobe this info will help you

Thank you Klaus, for your valuable suggests.


For the long trim indicator what kind of motor did you use?
for me is even more difficult to recreate the whole mechanism because obviously I'm missing all the inner workings, I will work with pulleys and chains to recreate the whole. In this regard I do not understand is the mechanism of the throttle. You have more pictures of internal throttles?


Thanks,
Simone

Hi Simone

For the long trim indikator I use an actuator, try this site for parts:

http://progressiveautomations.com/mini-linear-actuators/cat_16.html

I use a wire between the actuator and indicator whell to pull the indicator forward and a spring to keep the wire tight. Page 3 to 6 in my toturial.

I have mounted the potientometer in the throttle, but i belive it's easier to mount it on the actuator.

Dear Klaus,

LONGTRIM : i find in the page some actuators...which type of force?

 AUTOTHROTTLE : about DC motor i cant find yet...do you have a online shop how to buy these? in the automathism there is only one DCmotor or two (one for each throttle)?

AUTOSPOILER :  you use another DC motor?

FLAPS : i find two switch actuactors on the pedestal. you have connected these to a Bodnar card or have them replaced with a new potentiometer

 Do you think something about the mechanism for the black yellow wheel ?

very thanks,

Simone

Long Trim: force in the actuator must be capable of pulling the spring that returns the long trim indicator. Almost all actuators could handle this task.

The actuator must be able to run at least the same speed as long trim indicator in FS



 _____________________________________________________________________

A/T is only guided by a common electric motor which pulls the shaft on which the throttle levers are mounted, bonding is through a slip clutch.

I use the same kind of electric motor to AT and spoiler.

The electric motor must be at least 40 watts.

I use an electric motor with data: 40 volts and 1.65 amps max.

You can calculate the Watts = Volts x Amps  =  40 x 1.65 = 66 watts.

Since I only provide the motor whit a supply voltage of 24 volts then should the max watts be: watts / volts x volts  =  66 / 40 x 24 = 39.6 watts

Auto Throttle electric motor may well be lower in wattage, but the spoiler electric motor can be bigger in wattage.

http://www.parvalux.co.uk/uk/products/step4.php?voltage=DC&Category=Motors&MotorType=Permanent%20Magnet&GearType=Motor%20Only

Or try RS Components

I've been lucky to get my motors through my work, they were discarded, and I've even restored them.

Dear Klaus.

happy new year! 

if i send you my throttle are you able to configure it? i cannot find solutions for my throttle.

I would pay any costs, including labor!

Thanks,

Simone

Hi Simone and happy new year.

I would love to help with your throttle, but I have no opportunity to do it for you, I'm a little pressed in time, and I have many projects to do both at home and on the MD-80 project.

But take some pictures of the throttle and send them to me so I can make some suggestions, becurse your throttle it's not quite as complete as my throttle. I think you are missing the clutch that connects throttle lever with the A/T electric motor, so here must be invented a new clutch system.

Here in Denmark we have schools that train apprentices in the electricity and within machines if you have similar schools, there may also be help available here.

Ok Klaus, no problem!

i will try to rebuild the mechanic of pedestal like your tutorial step by step.

Excuse me if i will asky you some questions from today:

First of this:

You have attach the picture of actuator flap (where there is a flat cable connect to many pins). 

How to connect some pins in to the bodnar card?

Thanks,

Simone

Hi Simone.

Just ask away, that's why we have a forumWink

I answer as best I can, and there's something you do not understand, please ask me again.

Here is an opportunity to see the throttle from many angles, use your mouse to move around.

 

Follow my tutorial II page 16 to 18

The first thing you should do is to check and adjust the electrical contacts in accordance with the form at the bottom of page 17

Once you have done this, install the wiring between the electrical contacts, here it is the black wires.

Afterwards installed wiring from the contacts and out to BU386 that is the red wires



This is the alternate connection from the toturial.

Klaus.

today finally start to implement my throttle. I start with flap levers. I connect all wires using a flat cable like your tutorial using also the original actuator switch (i use the first connections) , there are the problems :

1 - i assign flap levers from 0 and slat ext. :

     sometimes work correctly, sometimes go directly to flap 11

2 - Flap 11, 15 , 28 and 40 dont work. I use your configuration in the bodnar card, i try also with the alternate in this post...yet!
Thanks for your help,

Simone

Hi Simone

 

Have you ajusted the electric contakts, like this:



If you take the contact A this shall link interconnection between pins 2 and 3 in flap setting 15-28-40

Thanks Klaus, tomorrow i try with this configuration, but i dont understand this scheme.

Have you a simple scheme with contacts like the last you sent in this topic?

Do you said me which diameter has the two Throttle wheels (where it is also connected the reverses axis?)

 

thanks,

Simone
