KC-135s are crap. Just a personal preference as an aerial transporter

I knew that the Navy preferred its own special blend (JP-5, rather than JP-8) for reasons of fire-safety in the carrier environment, but I hadn't considered that differences would exist in the pressure and flowrate. I suppose this makes perfect sense in the context of the AF needing to be able to support not just fighters and other "small" tactical aircraft, but also the bigger strategic stuff (bombers, heavy airlift, AF1, etc.) with massive fuel capacities. In that context, I'd also guess that trying to mate a 747 or a B-52 with a drogue system might prove a bit challenging. The Advanced Hawkeye, almost ready to hit the fleet, comes with a probe... can anybody see a problem refueling from a Hornet? I knew the F/A-18 was a big bird, but seeing it in context against an E-2 like that really puts things into perspective. (edit: wait, that's not an 18, is it?) Cruise speed on the Hawkeye is 256 kts, which I'm guessing is at the lower end of the Hornet's maneuverability envelope.

How much fuel do those hornets have at max?

Why, yes i always like to run twin turbos just to spin the air in my intake.
Take a look at the way the idiot plumbed the turbos at 6:33. |

I'd like to take this aviation moment to post some photos from yesterday.
Son is not impressed. https://www.miataturbo.net/attachmen...ine=1369057672 Dad explaining his first ever flight in a plane (like the Boeing Stearman PT13 behind him) where the pilot did an outside loop over his house. https://www.miataturbo.net/attachmen...ine=1369057672 dat afterburner https://www.miataturbo.net/attachmen...ine=1369057672 It's not just a catchy OMD song, it's a doomsday vehicle. https://www.miataturbo.net/attachmen...ine=1369057672 Hmm. https://www.miataturbo.net/attachmen...ine=1369057672 |

I dont know much about those systems, but i know they exist... lol Im just wondering how they help at all, without exceeding the efficiency of the supercharger...

I've been to the main museum on the mall, and was kind of underwhelmed to be honest. (Prior to this, I'd been to Wright-Patt several times.) Also, had no idea Enola Gay was out on public display. I've visited her sister ship Bockscar, which delivered the FatMan gizmo to Nagasaki: https://www.miataturbo.net/attachmen...ine=1369062661 https://www.miataturbo.net/attachmen...ine=1369062661 (Stock photo. That railing is new- when I was there, you could actually walk right up and touch the airplane.) |
Flash Gordon anyone?
This is actually a for-real ad by a UK-based conservation group which is opposed to the culling of the badger population in certain regions by the government. BE THE MUSHROOM! |

Use a turbo to make more than 14.7 psia on the intake side (like 14.7psig or 1 bar of booooossstttt), and you'll sure as shit get that increase in DP on the output. http://dieselmotorok.hu/Detroit%20di...V%2092%203.jpg So yea, twin charging works. :dealwithit: |

Detroit's were the OEM for twin charging, I dont know if they were first. A 2 stroke diesel needs a positive displacement pump to make the engine work, so they all have roots "blowers" (superchargers to the rest of us) to push the air through the engine.

In this scenario though, it appears that the flow from the turbo compressors will go right out the front of the SC intake. The pressure in the intake will surely rise, but pressure is just a side-effect. I can't imagine that setup (the one on the muscle car) can be flowing more through the SC when both those turbos are at full tilt than it would if they weren't there.

I was thinking maybe he just wanted the "PEW PEW" sound of a BOV, but where would the pressure be coming from to make the "PEW PEW", so maybe no PEW PEW |
The question, which we may never have an answer to, is whether the base of the uppermost red plenum (the part with the butterflies) is open to the stage below it or not.
If it is open, then the turbo compressors will simply recirculate air within the plenum, heating it slightly, but accomplishing little else. (They will generate no pressure, even across the compressors, since the compressor outlet is feeding the compressor inlet.) This seems unlikely to me. If the base of the plenum is closed, then what we have here is a compound charging system, albeit a very oddly arranged one. |
