StratoSphere Posted January 16, 2020 Author Share #26 Posted January 16, 2020 here are visible the three helmet's connection other than the main (green) oxygen hose. 1) the bell-shaped comm. plug does exit from collar's neck skirt, 2) the small black hose for expiry/compensation valve does stay parallel to the larger green hose and goes straight to its receiving outlet at the side-mounted connector block (see forward), 3) the black-sleeved cables for communications and visor de-fogging comes from helmet's chin and connects to its receiving plug.

StratoSphere Posted January 16, 2020 Author Share #27 Posted January 16, 2020 Left side view of GSh-6M. Some changes to the closure system of later GSh-6A, plus the much simplified rotating ring ensemble (here still massive and complicated). Link to comment Share on other sites More sharing options...
StratoSphere Posted January 16, 2020 Author Share #28 Posted January 16, 2020 The KP-27M ensemble, emergency oxygen kit normally stowed between pilot's seat cushion and survival kit pack. In emergency situations it will give instantly oxygen under pressure to the KP-52M connector block that does stay attached to seat harness' left leg strap during flight. Operation can be automatic (in case of ejection) or manual (if aviator still stays inside the cockpit but wishes to activate the system for whatever reasons).

StratoSphere Posted January 16, 2020 Author Share #30 Posted January 16, 2020 It's a small metal case 36 cms. x 32 cms. x 2.5 cms, weight 5.3 Kg., KP-27M for (Parashiutnniy) Kislorodnniy Prìbor, -27, M(odernizhirovan). The 11 + 1 small bottles are charged with oxygen at very high pressure, 150 kg/cm.2, that will be slowed down to breathable pressure by the brass serpentine capillary tube (about 85 coils of 19 mm. diameter, total almost 5 meters).

StratoSphere Posted January 16, 2020 Author Share #31 Posted January 16, 2020 Here the guy does wear a full harness and is connected to the KP-27M, just to show how works, of course the kit should stay under pilot's cushion. Link to comment Share on other sites More sharing options...

StratoSphere Posted January 16, 2020 Author Share #34 Posted January 16, 2020 Taking into consideration how the case would show up when stowed at its place, we have here the high-pressure oxy. hose connected to the KP-52M connecting block (that will deliver both high-pressure oxygen for breathing, and high-pressure (still oxygen, not air) to inflate the pressure suit in emergency. Cable is for activating the system. The pull from ejection seat rising up at the firing sequence will activate the whole; however if required, the aviator can always start the flow manually via the red knob while still staying in the cockpit.

Obviousman Posted October 15, 2022 Share #39 Posted October 15, 2022 On 1/16/2020 at 11:22 PM, StratoSphere said: GSh-6 series helmets, all have their inside small sun shade being operated by external lever. A very thin plexyglass layer, just covers airman's eyes againt the strong sunrays at high-altitude. Visor does retracts by means of a complicated swinging brace. Slightly off topic but hoping no-one will mind. I have 2 x GSh-6 helmets, an A (six latches) and an LP (eight latches) I believe. Can anyone tell me more using the labels inside? Size, etc? Also, the -6A won't lower the visor; the handle just has a bit of give up & down but the dark visor won't lower. Can I remove the interior section where those screws are? Will that give me access to the dark visor? Thanks! Link to comment Share on other sites More sharing options...
