Been on the real Boeing 747 simulator, which feels exactly like flying, except with having a whole load of students inside they had it in a limited motion mode, so it would not do the full range of motion. Then we got to see it running from outside, where it sat a floor or so up in normal use, to get the full range of motion it was capable of. we could watch the video shown inside, on the Sony projection TV sets, on some smaller Trinitron monitors.

[@corzaplayz]

Dexxter they seem to be placeholders for the standby instruments. So in case a display failure, or engine, or power, they will continue to operate, through a different battery system, which only they run on.

[@tuttocrafting]

Is the motion control/hardware integration layer java based or is the whole simulator running on java? O.o Generally I've seen FSX and X10/X11 layers to interface with the hardware. But I think that only FSX can properly be synchronized into multiple instances. (I've tested X11 a yet ago, with the full world mapping, that thing is heavy! I have a decent hardware but having 8 core and 16gb of ram completely filled was a little scaring. Looks like that simulation is quite resource intensive) I would have used a rack server with VM and pcie passthrough to render each display.

[@EEVblog]

I think the hardware programming language for the interface is "java like". More on that when I go back there.

[@tuttocrafting]

That's so cool! Thanks for the reply!

[@simulatorsolutions]

A small VB based application feeds the X, Y & Z acceleration values from the Simulator Software (PSX) to the motion computer over a serial link. The hardware integration is provided using a small Java app that connects the SimStack boards to PSX. Then there is a .NET application that links the visual system (Perpar3D) with PSX. The visuals are being run from a single computer using a high end video card with multiple HDMI/DisplayPort outputs. Hope this helps.

[@pocoapoco2]

Supposedly these simulators are so realistic that pilots can be trained on these and immediately fly an actual aircraft with passengers and all after being fully trained on the simulator.

[@sparkplug1018]

Thats sort of correct. A new pilot will still need a certain number of flight hours in the simulator, plus a certain number of flight hours as a first officer in the actual aircraft with a captain who is certified to train new pilots. So yes you can get all of your type ratings in the simulator, but theres still a good amount of training required in the actual aircraft.

@@Balthazar030 Well if they have a bunch of PCs, it must be able to run the simulation across a bunch of nodes, even if it is single-threaded. I would assume you could run multiple instances of the sim program on a single computer if you can have multiple instances spread between computers. If not, they could combine all the separate machines into one server running separate VMs, with different operating systems for each VM if needed. Then each VM would have, say, 2 cores and a few GB of ram. But maybe you would want to go Intel with fewer high-clock cores.

[@richfiles]

I'm building a Kerbal Space Program instrument panel that will fit into my desk. Nothing remotely as fancy as this, but I got a real Flight Director-Attitude Indicator that I want to use as my Navball. It's an ARU-11/A, and I think the power/reference in is supposed to be a 120VAC 400 Hz source, and I think the synchro inputs are supposed to be 28VAC... _I THINK._ I need to design a controller that takes the digital data from the KSP serial IO communication mod, and my 400 Hz reference, and creates the 10 outputs necessary to drive the unit. I'm only 90% sure those voltages are correct, and I have NO IDEA how much power is required for the Power/Reference, or for any of the individual synchro inputs. I'm also unsure of how to couple this. I was thinking of using some of those integrated audio amplifier chips, the kind in a SIP package with holes for heatsink mounting. I figure those are designed to drive inductive loads, and can push some power. Part of my lack of knowledge, is in regards to whether I even need them for all 10 inputs. Obviously, I need to provide power on the reference input. Don't know if I need any significant power driving for the three synchro inputs though. I'm still unsure how to couple the outputs. I'm guessing I'll need transformers to get the voltage coupled up to where it needs to be. I'm thinking that on the secondary side, I'd tie one side of each triplet of transformers together, to create a Y configuration, and then attach the three synchro inputs to each of the other three secondary leads. I'm thinking I'll have to keep the outputs of the audio drivers isolated from each other when feeding them into the primaries. One of my concerns is even finding transformers that will even do the job. I'd be curious how they drive instruments that expect synchro signal sources.

[@sparkplug1018]

Not entirely sure what your answer is, but you'd be much better off typing this up on the forum. Im sure there are a lot of people over there that can help with this.

[@simulatorsolutions]

Stay tuned - I think that Dave will do another video on Synchros and Resolvers. Fascinating things - it took us two years to develop a digital interface to these analog units...

[@richfiles]

@@simulatorsolutions This sounds very relevant to my interests! I definitely belive it could take time to get it right! I used to work for a company called Tachtronic Instruments (not to be confused with Tektronix). I mostly worked with brushless motors and particularly, the drives. 3-phase units that switched outputs of 295V @ 45A. We also made synchros, which I helped with from time to time, usually when we got busy. For some time, I'd considered the possibility of just buying some surplus synchro control transformers, and mechanically driving them with a traditional motor solution, but I realized that was a bit convoluted. I have a thread on the EEVblog forum where I theorized about how to do it, but I'd not actually formally designed anything, much less completed the project. Work got busy, and it sat on the back burner for a couple _years._ I was still playing KSP version 0.25 when I first began the project! Anyway, My theoretical solution was as follows: • Analog steps •• Digital steps • A hardware generator creates a 400Hz sine wave • The 400Hz sine wave is fed into a pair of Op Amps: One inverting and one non-inverting. This creates two sine waves 180° out from each other. • The two sine waves are fed into an analog switch IC. The microcontroller can select the inverted or the non inverted signal to pass through. • The selected sine wave is fed into the reference of a 12-bit MCP4922 DAC. • The microcontroller sets the scaling of the DAC, allowing the DAC to function in multiplier mode, attenuating the sine wave on the reference. _For reference, there are a total of 9 analog switches, and 9 DACs, three per axis, for each of the three different axes. Each circuit is just repeated 9 times._ •• The Microcontroller receives serial data containing the Yaw, Pitch, or Roll angle. (Each axis will be a separate PC board, and likely have it's own microcontroller). •• The microcontroller will add 120 and 240 to the angle received, then check if any results are 360 or greater, and if so, subtract 360 from the result. •• The three values are used to look up the attenuation value from a lookup table of sine values. (I think that might be easier than trying to calculate sine. Not sure) •• Each of the three values returned are checked to see if negative. If negative, the associated analog switch has it's state set to select the inverted sine wave input. •• The absolute values are sent to the three DACs of each axis. This allows the DAC to function as a multiplying DAC, scaling the analog sine wave on the reference. • The output of the three DACs are fed into audio amplifiers. • The three audio amplifiers are fed into transformers to couple into the synchro inputs of the FDAI. (this • The non-inverted reference is fed into an audio amplifier, and is fed into a step up transformer to power the FDAI and provide it the reference source.

[@richfiles]

@@simulatorsolutions My favorite way to explain a synchro visually is to hook it up to a 4 channel scope, set the reference up top, and then line up all three outputs of the stator below it (so they overlap). You can visually perceive the angular rotation of the outputs when doing that, and you see how all the zero crossings stay in phase. I can't tell you how many times I've seen people think these work more like a resolver. Very different beasts! Of course, they are visually interesting on a scope as well. All equally interesting. Really cool demo, if you ask me!

[@movax20h]

Mostly due number of screens and inputs. It definitively could be reduced to smaller number of computers, but it is hard to find a single motherboard that will support so many inputs and outputs, even with PCIe expansion bridges, and you might be bottlnecking some stuff. Multiple machines are probably cheaper overall and easier to troubleshoot or replace components.

[@ericveschi4904]

Because one task by computers is better than only one computer doing several tasks. By example, X-plane and FSX, and maybe P3D are designed to be able to use several computers at the same times. One dedicated to simulation, one per view, one for others tasks. The goal, earn FPS and simulation with minimum latency. In X-plane if you are using a second screen on the same computer, you will have a fps drop.
