Cold start: I can't get the Shkval working

[Sholtz]

I have about a bajillion check lists in pdf form, urls, videos, etc.

 

No matter which one I go through by the time I am done I still don't have a working targeting system and the Shkval is off.

 

Where is the damn ON button for the Shkval?!?!?

[JG14_Smil]

Targeting control power switch on - l/s console.

 

Two generator swtches on the wall panel.

 

Make sure throttles are up two positions.

 

It has been a while for me.. sorry if I got anything incorrect.

I think you may have nailed it, I thought the two AC switches for left and right generator was only for ground power but a peek at the manual leads me to believe that if I don't have those on then there will not be enough power for the Shvkal....will test when I get a chance but if anyone can confirm would be handy :)

 

At least this is what I think you are talking about:

 

6. "ТОК ГЕН. ЛЕВ." (Left generator) switch. After the engines are fully operating, the throttles are in automatic mode and rotor RPM is stable above 83-85%, you may turn on the left generator. This will supply power to the main AC and DC busses and onboard batteries. [LCTRL + LSHIFT + Y]

 

7. “ПРЕОБР АВТ – РУЧН” (Electrical power inverter auto – manual) switch. This is a three-position switch that allows DC power to be converted to AC power that is required by several onboard systems. The up "АВТ" position provides automatic conversion, the down "РУЧН" position requires manual conversion and the middle position turns off conversion. [LCTRL + LSHIFT + I]

 

6–79

8. "ТОК ГЕН. ПРАВ." (Right generator) switch. After the engines are fully operating, the throttles are in automatic mode and rotor RPM is stable above 83-85%, you may turn on the right generator. This will supply power to the main AC and DC busses and onboard batteries. [LCTRL + LSHIFT + U]

No, the AC generators are not for ground power, they are on board AC generators that convert engine torque into the AC electric power that many avionics systems (such as the Skhval) absolutely require.

Smil is right.

 

* Start engines.

* Set the throtles Auto position.

* Turn on L & R generator switches.

* Turn on K-041 Targeting and Navigation System power.

 

That's it.

Interesting thing that took me awhile to figure out:

I always thought, "If there's an inverter, why do I lose the Shkval when rotor RPM drops? And the doppler, too?"

Low and behold, the manual states that the POS-500B inverter only supplies the:

• Radar altimeter
  
• Oil pressure switches
  
• Fuel gauge
  
• G-load accelerometer
  
• RPM and EGT indicators
  
• Vibrations monitoring system
  
• IFF equipment (important when it's modeled)
  
• Warning and indication systems
  
• Audio tones for rotor RPM drop (helpful, considering that RPM drop is one of the more common things that'll kick in the inverter in the first place)
  
• Emergency instrument panels illumination
  

 

Note that the Shkval and Doppler aren't on that list.

 

Just an interesting thing I discovered awhile back.
