Motion simulator for Il2 sturmovik flight simulator-swivel chair?

Hello i am trying to figure out my motor specs and i am a little confused!

In Simcalc i enter a value of "Motor Torque" to 60 N*m , and a "Motor Speed" of 80 r.p.m. So i want to ask those values are after the losses of the gearbox or before? because if they are at the final output of the gearbox shaft then i need much more Kw in order to compensate for gear losses. I think if i am not wrong that 1:50 gearbox efficiency is about 50% , so how many kw motor do i need to buy in order to have output torque 60 N*m at 80 r.p.m?

Thank you!

Does Simcalc works for 2 dof compact designs too or is it dedicated only for shoulder levers? I am trying to set Z dimension of Rod mount position lower than 0.1 m =10 cm and it will not let me. Is there any other way to compute construction parameters for compact design?

Thank you!

Its not a compact design i could say since Y=-0.5 meters for Rod mount position and Y=-1.5 meters for Motor Postion , activation will be under footrest.

1. For Z=0.1 meters ( Rod mount posotion) i cannot set a lower value...why?
2. "Ctc rest angle" is very critical for pitch rotation , but its value of 50 degrees its just an eyeball estimation from me since i havent done any autocad shematic to see exactly what the right value should be. So how can i be so sure of my final pitch rotation degrees before the construction of the project?

If i want to have 50-60 N*m torque on my gearbox shaft for about 60-80 rpm then going backwards i need for 1:60 gear ratio x*3000=50 N*m * 60 R.P.M => x=1 N*m at the motor shaft before gearbox , but if i have gearbox losses of about 30% then i am in need of 10/7 N*m before gearbox. So for 3000 rpm i need P=T*RPM/9.55 => P=10/7*3000/9,55=448 WATTS!!!

So where am i wrong since i havent seen such a big motors till now?

Hello to all!

Finally i decided to order a dof 3p from dof reality..

In case i have any issues while trying to tune it i will need your help.

Thanks a lot for your help so far!

Finally managed to make my dof 3p reality motion platform to work!!i also managed to make my chair turn left or right like a classic swivel chair by putting a heavy duty swivel plate underneath and between two blocks of hardwood. Everything works as i would like.

Indeed i see some "cogging" effect especially in pitch up and more during pitcing down. I managed to eliminate it a little by increasing speed setting lowering max telemetry value in sim racing studio. I set pitch to its maximum value and roll to about 60-70% as i get very nice immersion feeling that way and at the same time not be in danger to fall off my chair during rolling!!! And at the same time i can be as competitive as i can during dogfights in multiplayer servers!!! But its not easy...I also have to put a safety belt...

1. Some times i hear some knocking sounds especially during combined movements( roll with pitch at the same time) like motor levers coming to their end limit . Can this issue damage my platform? Its probably due to low pitch max telemetry value but i get nice speed that way...

2. As a next step i would like to built some pneumatic DIY g-seat functionality in my chair. So the problem is that Sim Racing Studio cannot support such a function. So is it possible to run SRS for my platform and at the same time another program for g-seat without any conflicts (e.g ports..).? or should i control platform and g-seat only by one program?

Thank you in advance!

Immersion feeling is fantastic althought i became a worse dogfighter!!!
