Wayne,
A Buckaroo Banzai referance.
I will never doubt you again.

Wayne beat me to the Oscillation Overthruster guess. That's my default answer to anything...

Dr. Lizardo: "Laugha while you can, monkey boy!"

Lithgow is just awesome in that movie.

Buckaroo: "It flies like a truck."
John Parker: "Good, what is a truck?"

Great stuff!

Re: Anybody know what this is?

2 seat ejection delay timer. OK, so why is it in it's own nifty little over engineered box. First, anything dealing with the ejection seat(s) is over engineered. If you're going to eject, something has gone bad, really bad and odds are you've incurred some damage. The last thing you want is for the ejection seat and supporting systems to be fragile. Second, the main design for this a/c was a single seater, so with only a limited number or a/c having backseats (for training mostly), the delay timer is another control device that is added to the forward cockpit. Hence the self shielding, easily bolt just-about-anywhere ability. (may have been in the backseat on some models)

So, how does it work. Well the top part, 0-3 second will delay the firing of the second seat. Notice I didn't say which seat. The toggle switch below selects who gets to go on the ride first. In it's present position, the back seater gets the honors. If you want to go together, it really doesn't matter who's got the honors, just set the timer to 0. Although not recommended, you do have the choice.
So, yes, the word on the top dial indicates seconds. BM-2 basically stands for 2 seat selection control. The "N" #### is version
control.

I don't have a clue either ... But I feel really refreshed from my night at a Holiday Inn Express....

There should just be two settings on this Soviet/Russian unit: 1) Farnborough; and 2) All other locations & above 300 meters.

Seems that you'd always want the GIB to go first to avoid ingesting the front-seater's "ejecta". You jet jocks have a different perspective?

Re: Anybody know what this is?

A co-worker of mine did a tour in Afghanistan a couple of years ago. While out on patrol one day they came upon a boneyard of MIGs. He hopped in a cockpit of one and grabbed a couple of souvenirs. He doesn't know what this is or what model of plane it came out of. In his words, "We didn't stick around too long". Anybody got any ideas what this is?

I'm guessing intervalometer for an aii to ground rocket pod.
The cyrillic text transliteraties to "Sekundy" which literally means seconds.

Most russian groundlaunched ballistic rocket systems are coded With a "BM" prefix (boyevaya maschina, or "fighting vehicle") like the BM-21 for example. This might translate over to ballistic rocket packs - I'm just guessing. An obvioulsy, the time in seconds is the firing interval between rockets, which will help determine the dispersal pattern. I'm also guessing that these came out of a ground attack aircraft, as the Soviets tended to not need Air superiority in Afghanistan, and thier close air support was the stuff that got shot up the most.

I was at Entebbe in the mid 90's during our Rwanda relief eforts. We set up shop on the old side of the airport that Idi Amin abandoned after the Isaraeli hostage rescue raid in 1976. Nothing had changed since that day - the old tower was still shot to hell, all of the damaged and destroyed migs of his air force were abandoned in place. Lots of Army types used to crawl all over them and mess around in the cockpits - until someone with some aircraft maintenance experience noticed that the ejection seats were all armed, with not a safety pin in sight.


I'll have to dig through my photos - anyone interested?

Re: Anybody know what this is?

The rocket interval timer sounds good, but 3 seconds seems like an awfully long interval when going Mach . anything. Even .5 second seems like a long interval for multiple anythings that blow stuff up. From the paint fading it looks to me like the BM-2 spent most of its life set on 3.

I think we can all agree that it is some sort of interval timer. So, what systems could that be applied to? A couple that come to mind are deice and windshield heat.

Re: Anybody know what this is?

You all have me rolling with your answers. My thought is some kind of timer as when you turn the knob there are graduates in between the numbers. Kind of reminds me of the timer in a public restroom for all those hitting on the BM. I'm thinking that I will open the box and take another picture.

P.S. Fenceliner01--hell yea I'm interested. Talking history here, you know.

Re: Anybody know what this is?

Is this a switch with detents or is it continuously variable?

Re: Anybody know what this is?

O.K. this is it. I stayed up all night and researched this thing and I know this is accurate information validated by a flight manual:

This is from a Czech aircraft. The part is called (in English of course), a BIO-HAZARD SUBJEGATOR FOR AERONAUTICAL RELEASE OF WASTE MATERIALS. In other words, an electrical flush valve for in-flight use.

The rotating switch simply increases or decreases the ampherage available according to the need of the moment. To determine which way to rotate the switch you simply need to know that more ampherage reduces orafice size resulting in restricted output and lower ampherage expedites easy release. Experimentation will untimately provide the correct setting for in-flight use. Under no circumstances, turn the unit off with the detented switch marked BK/L. Ultimately, failure to use the unit will result in an explosion.

Don't throw me outta here, these are just the facts!
