Mu-2

While updating cfg to my format I see there was no Alternator/Battery volts specs so just adlibed till info is avail..anyone got idea what these would be?

Krazy:

I don't quite understand the question your asking. Are you asking what the Alt / battery volt specs are for the particular aircraft you posted?
 
Krazy:

Here goes!! Hope this helps..

From what I see posted, you have a twin engine aircraft with generator / alternator on each engine, 8 circuits or bus bars (0 to 7) that all your stuff goes thru (or wired too to get their current), a 24 volt system, a generator / alternator that puts out max of 28 volts and 60 amps and your electrical is all controlled thru your "master switch"..

All this info came from the top section.

The bottom section just tells you what bus bar (circuit) all your particular device's are wired too (first number), the maximum amp draw that may occur for that particular device which is usually protected with a fuse or CB (second number), and the minimum voltage it will take to allow that device to work..

Another words your "flap motor" is wired to the "main" bus bar and even tho it might have it's own "flap switch" to control it's operation - it still needs the "master switch" on to get power to the flap switch, it's protected with a 5 amp fuse / circuit breaker and if you don't have at least 17 volts going to it for whatever reason, it will not work!!!

I hope this helped answer your question. Let me know..

Nope... I added that section..look in your cfg and you see the whole top section isn't there...I'm just wanting the correct values is all...hell they may be correct as far as I know...

This is what I added:

[Electrical]
; Bus Types: 0 = Main Bus (Most Components Connect Here)
; 1 = Avionics Bus
; 2 = Battery Bus
; 3 = Hot Battery Bus (Bypasses Master Switch)
; 4 = Generator/Alternator Bus 1 (Function of Engine 1)
; 5 = Generator/Alternator Bus 2 (Function of Engine 2)
; 6 = Generator/Alternator Bus 3 (Function of Engine 3)
; 7 = Generator/Alternator Bus 4 (Function of Engine 4)
//
//
Max_Battery_Voltage = 24.0000 ;
Generator_Alternator_Voltage = 28.0000 ;
Max_Generator_Alternator_Amps = 60.0000 ;
Engine_Generator_Map = 1, 1, 0, 0 ; @ 2 Engines
Electric_Always_Available = 0.00000 ;
 
Your right Krazy - I just looked in my config and it's missing!!! Apparently it works ok without it because I haven't had any problems but usually it's there...

For what you added, it looks ok to me. Maybe someone from PAD will jump on here at some point and explain - they might not know it's missing...

Sorry it took me so long to catch on!!! :banghead:
 
MU-2 electrical

To be honest we were not aware of the missing [electrical] lines but when some piece of required information is omitted from the aircraft.cfg FS generates a default situation ...which is what we would have put in anyhow.

Bob, I sent an e-mail to Barry, but I'll let you know also, The NZ Livery on your main page is credited to me, but I didn't do that one. It was done by GNZLAP.
 
Good Day, Ladies and Gentleman:

My name is Matt Bryden, I live in Tulsa, OK, and currently work for Aircraft Components Company http://www.acc2tulsa.com. Our shrinking company is currently in the process of being acquired by Intercontinental Jet, which is a wholly owned subsidiary of Mitsubishi Heavy Industries America.
Imagine my surprise to hear from Joe Zerilli informing us that PAD was writing a MU-2 for MSFS: Positive publicity for the MU-2? That's a rarity!
Up to this point we at ACC have tried to encourage the enthusism that has been so missed regarding this A/C.
Why should you care? Krazy: Despite the fact that Japan is an island, the Japanese resisted the use of hydraulics for this plane. The only things that utilize hydraulics on this plane are the brakes and the propeller, and the two systems are independent of each other. The rest is all electric. Hence, the "default" #s cannot apply to this plane: here's what I can tell you off the top of my head--mind you, it's Sunday and the Genesee is flowing, so corrections will likely ensue.
The TPE 331's on both the Solitaire and Marquise models, (MU-2B-40, and -60) are sporting Lear-Siegler (now Lucas) 23046-028 Starter Generators rated at 200 amps each. The MLG door motor usually eats up ~ 18 amps (circuit breaker=25A). The landing gear motor drives all three struts down through a series of gearboxes , driveshafts, and U-joints---It's the biggest load--rated @ 75A, and it usually needs to suck up about 50-60A to finish its task. The flap motor generally requires 17-25A.
I'll see if I can't find a page in the books we have that will present the electrical systems succinctly, but that just may be a very tall order, sir. Wish me luck, all, and please permit me to thank everyone who greets this magnificent beast with the respect it deserves.

PS: I rob the images presented on the web and include them in the rotation of pics presented on http://acc2tulsa.com, and then I inform the author(s) that I robbed it(them). I know, this kind of behavior is heinous, but I simply can't help myself. You cats are just presenting too many cool images. I hope the rest of you will be as forgiving as Bob May at PAD has been.

Thanks
 
More MU-2 stats

Fuel Boost Pumps
2 x 10 Amps maximum, each, which run throughout any flight. Average #'s for each pump = zero flow: 5.3A 1000 pph: 6.4A 2000 pph: 7.5A

The transfer/crossfeed pumps run at about 1/2 the flow/amperage of the above.

Annoyingly,

Matt
 
Do the Garrett turboprops smoke at all? PT6-A's have a slight trail but I don't have any recollection of the Garrett engines IRL.

My thanks too, GNZLAP!!! Very nicely done. She looks great all around. :applause: :applause:

Thanks for the kind words! This is good encouragement for a wannabe painter - see it found its way onto the PAD site also :mixedsmi:
It's the wrong aircraft of course...Hamilton-based -KOH is the stretched version, if PAD do one I'll update (and improve) the paint.

Thats pretty cool information Matt!

True that some corporations are shunning FS and others are embracing it. The people that sim are huge on the list. Many actual owners and perspective buyers now sim to get a feel for the plane.

Great to hear that Mitsubishi is still in the works with their aircraft. I hope business is good this next coming year.

Still enjoying this a/c very much. Great looking visual model and interesting flight model. Finding it difficult to reach the top cruise (eg 315 knots ground speed @ FL20) and the takeoff acceleration seems a little fast though, but having fun tweaking and experimenting . .


 
Expat, I've noticed the same 'super' acceleration on take off. They accelerate quickly, but not like that. I find 50% throttle on take off, then slowly increase during climb out. I haven't tweaked the throttle settings in the config yet, but if you do, please let me (US) know.

Thanks,

Bob

The airplanes top cruising speed is not 315gs. You dont measure aircraft cruising speeds by their ground speeds because this speed is greatly affected by wind. You are looking for between 310 - 315 knots TRUE AIRSPEED. She'll do it, not to worry ;)
 
Just looked at The PAD website, and apparently the MU-2K is on it's way soon.

Image is from their site...
