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

How much fuel do those hornets have at max? And wouldnt that add a big bulky system to the aircraft as well?

Interesting.

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.


Wow.

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.


The later models of the FA-18 were specifically designed to support a buddy-refuelling role, from four external tanks mounted to the under-wing hardpoints where you'd normally expect to see ordinance (and I believe it can support a fifth under the fuselage as well) each carrying 480 gallons.

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.

ROFLMAO I cant believe someone would do that ****!!!

I'm gonna guess that the exhaust from the hornet will want to suck that bigass dish from the back plane up into the exhaust.

I'd like to take this aviation moment to post some photos from yesterday.

Son is not impressed.


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.

It's not just a catchy OMD song, it's a doomsday vehicle.



Hmm.

im curious... it looks like the turbos are just plumbed into the intake funnel... but, ive seen military vehicles, and some big rigs that have a turbo system, fueling a supercharger. 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...

Anyone on here know anything about those systems, that would like to chime in?? im really curious now. lol

This particular setup just looks like its pumping the air back into the funnel, so there wouldnt be any pressure... unless he has some kind of ductwork inside the funnel that we cant see, sealed off, pumping into the supercharger itself...

I'm pretty sure that polished piece below the painted funnel is closed on the top. At least I hope so.

Are those from the Udvar-Hazy Center?

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:

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.

You would hope so but the scoop looks like it flows perfectly into the carbs. With the rest of the work that was done fabbing a smoother flow to the turbos would be expected.

golftdibrad

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.



now a blower is just a positive displacement pump, for a given rpm and flow rate it will produce a given pressure differential ratio. 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 **** get that increase in DP on the output.



So yea, twin charging works.

supercooper

nice, thanks... i was always curious... i know twincharging works, but i had never really looked into how the turbos feed the SC. the setups ive seen (not many.. like, 2), had a NON-intake mounted SC, and the turbo and SC both fed into one intercooler, and then into the intake manifold, so the turbos didnt feed the SC in those cases.

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.

supercooper

My thoughts were going in the same direction.... soooo..... does anyone else on here think this man has too much money, and not enough sense??? or, are there unseen purposes to his setup?

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.
