AGD-1 1122A tandem drive

Я совершал стыковки и расстыковки, я выходил в открытый космос... и там парил.

Nice. What's driving them and what's the power supply?

[@barjan82]

Both units are connected to the matching inertial platform, which you can see here kzbin.info/www/bejne/rn2Yl41rmbWWqdE Power requirement is 27V DC and 3phase 36V 400Hz AC for the inertial platform and the instruments as well.

I used agd-1 as a calibration source for repaired КПП-1

[@barjan82]

Aaah! The 1273-KPP instrument is still on my wish-list, as well as the КВ-2НМ inertial platform from the MiG-23. They are very hard to get.

@@barjan82 hi! If you want, we can discuss hours about Soviet avionics, I got and repaired a lot of devices, have big library of schematics, developed many control blocks and many others. Скв-2н I have some blocks, but main gyro is still searching. Got a chance to have one, but decided not to buy because it was damaged

Are you sure the right one is not radioactive? ☢️

[@barjan82]

I'm pretty shure that there is a very mild radiation from both units. Both instrumets are 1122 A-type where the dials are UV sensitive. I own these instruments for years now and hasn't grown a third ear yet 🙂

@@barjan82 worked with many avionics and my pass criteria - no any roentgen additional to background radiation! So, should be 11-12uR/h, no more! When I repair devices I also measure directly the dials because glass can stop low activity beta. For example, 20-30uR/h - trash.
