Air Conditioning In Military Jets?

Sat Mar 01, 2003 4:14 am

Stupid question, but I was wondering whether military jets (bombers, fighters, survelliance, transport, etc) had air conditioning for the crew?

They sure do. Airplanes are almost intollerable in hot climates without it. Also many mil airplanes are a dark color, and they really soak up the heat. The old European camo that C-5s had for example, increased temps inside to almost an intollerable level on a hot sunny day. Sometimes interior trim panels would melt in the troop compt from the heat. It would take a very long time to cool the airplane down in flight without A/C.

yes the E-3 does, though at 30,000ft with the massive cooling air we need, we have the heat on, not the a/c, though at descent I have seen the flight engineer make it snow, more than once, it is pretty cool when snow is coming out of the ceiling vent slats.

Even if the crew is comfortable, it takes a ton of cool air to keep the electronics cool. The crew chief I worked with at Andrew's described how important it was to keep the computers cool... he never once mentioned the pilot.

Lucky airforce the army chinooks and Black hawks don't have airconditioning if you don't count the blades going around  Big grin

I know this from first hand I worked on the Chinook.

One of the Tornado pilots told me that when they were in the Gulf, between the briefing room and getting the ECS on, they lost a litre of sweat.  Wow!

You are right Paulinbna about the helicopters.One minor addition is that UH-60Q models have A/C. They are the dedicated air ambulance airframes. Also AH-1's, now gone, also had a/c. All that window area made it a nice little airborne cooker without ECS. I think there was a pretty good EGT penalty however, and quite a bit of airspeed was lost due to the bleed air flow.

The F-14's ECS system is located on the right hand side of the fuselage below and behind the RIO. There are two heat exchangers located inboard of the two intakes. If you look at top view pictures of the Tomcat they appear to be "Venetian blind" style vents.

The avionics of the C-17 are so protected from heat that a warning horn goes off and the Left and Right AV busses trip if the temp is over 90 degrees. It can be over-ridden BUT, I sure wouldn't want to be the one making that decision to overheat millions of dollars worth of black boxes.

The answer is NO. Not all planes do. I was watching a special on discovery channel and they said the F-18's cockpit reach 120 degrees sometimes cause they DONT have ac.
