Posted: Tue Oct 04, 2016 3:06 am Post subject: Russian clock with electrical connectors

I had to remove the clock from my Yak 50 for repair. 

Then I noticed that it has two connectors for +27 v on the backside (as stated on the clock).

This is obviously not used on the Yak 50.

Does anyone know what the purpose is? 

Regards,

Jan

Light or de icing?

If I remember correctly, the Russian clocks were connected to the pitot heat circuit.  Thus if pitot heat was turned on, the internal clock heater was turned on as well.

Yes, indeed internal heating for the clock.

Yes, that seems a very plausible explanation. 

Anyway, as far as I know, not used on the 50 (not on mine for certain) although we also have a pitot heater.

Jan you must realize that the Russians pretty much use that clock and everything that flies from your  Yak 50 to spacecraft so I did a lot of different duties. Being electrically heated was critical and some of those duties George

Yes, that is absolutely correct. What puzzles me is that although beautifully made, these clocks are not that accurate, and, given that, I wonder whether keeping them warm makes any significant difference!

Thanks, that also explains why it’s not necessary on a Yak 50.

Posted: Tue Oct 04, 2016 4:42 am Post subject: Russian clock with electrical connectors

Gents, while we're on the topic, I've never used my CJ6's Soviet clock all that much. I'm wondering what the red button/knob on the left does? Photo attached. (I see that depressing it flips a red flag to white in the top dial...) The silver knob on right is for on/off, but needed for winding by any chance? Or draws its power from the main a/c bus?



Can anyone give me a quick tutorial on the clock's functions? 

Thanks-Â

Can anyone give me a quick tutorial on the clock's functions?Â

If I remember correctly, the Russian clocks were connected to the pitot heat circuit.Â  Thus if pitot heat was turned on, the internal clock heater was turned on as well.

I am glad to be able to assist.  

I wish I could claim credit for the picture, but I got it off the internet somewhere.  



I have one of these clocks sitting on my desk and while I am a typical male who can usually stuff it up without printed help, I had to hunt down some instructions on how to drive the thing.  



If the clock is inaccurate, you can also adjust the â€˜speedâ€™ by twiddling a screw on the rear.

I am running mine, after repair, on my desk. 

After 24 hours it is still indicates the correct time (to the minute, at least).

So IMHO, it’s more than good enough for use in a 50 or 52. 

Though I can imagine that the G-forces while flying or from aerobatics might influence the accuracy.

Had my -52 on static display at the Royal Navy Yeovilton Airday this year parked up near a Polish Navy PZL M28 Skytruck and a MIG 15 ... despite a 40+ year range of production the one instrument we all had in common was the ÐÐ§Ð¡-1 clock!



For a regime that specialises in one-size-fits-all there are surprisingly two variants (usually marked on the dial);



ÐÐ§Ð¡-1 = second hand operates with clock, stopwatch sub-dial 60 minutes



ÐÐ§Ð¡-1M = second hand operates with stopwatch, stopwatch sub-dial 30 minutes

And for those interested here's the bullet form of the clock instructions;



- performs a conventional Clock function as well as a Stopwatch and an Hour Recorder



- outer scale is the main Clock & single sweep second hand



- upper sub-dial is the Hour Recorder (HR) and the lower sub-dial is the Stopwatch function



- two knobs are mounted to the outer bezel;



Left function knob

- normal position (IN) winds the mechanism

- pull OUT & rotate hands to set time on Clock

- push IN to change the â€˜setting selectionâ€™ â€“ interlink between Clock & Hour Recorder

- each push moves a flag in the Hour Recorder dial - alternates Red, Red / White and White

- corresponds to â€˜Set Clock & HRâ€™, â€˜Set Clock, Stop HRâ€™ & â€˜Set Clock, Reset HRâ€™



Right function knob

- turn counter-clockwise to run mechanism, clockwise to stop

- push knob to cycle Stopwatch function: Start â€“ Stop â€“ Reset



Using the Chronograph

- Right knob turn clockwise - ensure mechanism stopped

- Left knob - wind mechanism spring until it begins to tighten

- Left knob: push knob IN until White flag shows, pull OUT to set the correct time & push IN



Red Flag : the White flag is replaced with a Red flag indicating system fully engaged

- turn Right knob counter-clockwise to run the Clock and the Hour Recorder

- Stopwatch functions (push right knob IN) available



Red / White Flag : appears on second push IN of Left knob

- Hour Recorder stopped, main clock continues

- Stopwatch functions still available



White Flag : appears on third push IN of Left knob

- Hour Recorder reset, main clock continues

- Stopwatch functions still available

Forgot got to add to my last post ...



A full spring wind gives at least 3 days operation and, with a diurnal variation of temperature (20 Â± 5) Â°C, the timekeeping is Â± 20 s per day.



The reliability is quoted at 94% over 2000 hours between 20 Â± 5 Â°C, which is only about 3 months continuous use? So not sure how well made it really is, even allowing for intermittent usage in a high vibration environment.



*** Pre-1970 production probably had the hands and dial painted in Radium 226, that has a half-life of 1600 years! ***



If you have a letter 'B' on the right side of the dial the hands & numerals are painted in harmless phosphorescent paint and a 'K' signifies just white paint was used.
