Ironically...it's the B lift fan configuration that actually can be retrofitted for these demands.

Yeah the computer interface alone would be a programming nightmare.

Right but you have double the work, double the chances for something to break, double the time for maintaining them, and double the cost to produce them. I mean fighters these days are pretty much to the point where the pilots body is the limiting factor. So the cost vs reward ratio just isn’t there. And the point you made about about using jet engines for decades is actually a benefit to having one engine as well. They have become extremely reliable and powerful. I mean it would be sick if they slapped in 2 F22 engines in the F35A&C or if they slapped two F35 engines in the F-22 with thrust vectoring. Talking another 16,000 pounds of thrust with full afterburner. Talking a 1.5 thrust to weight ratio lol. But yeah to maintain the same size you wouldn’t get much more power with 2 engines over one big engine. And instead of spending let’s say 8hrs an engine for 2 engines you can spend 12 on 1 and make sure it’s running perfect and still save 4 man hours.

Correct

@@forfun6273Uhh, dude, it’s the same engine in the F-22 and F-35. F119. Check yourself before you wreck yourself.

Look back at the C-130-J campaign. Can you imagine the C-130 without those improvements?

I agree. We should begin a refurbishment program on US existing F-35’s and offer them for sale to nations who qualify at a significant savings. Then replace all the US F-35’s with the GE engined F-35. Germany doesn’t need the range the US needs in the Pacific. I’d make a deal to Norway, Finland, Belgium, UK and Poland that would upgrade the systems on their current F-35’s and any used F-35’s they purchase to block 4 software and bring the older F-35’s up to the most recent release. These discounted sales would boost the alliance and allow the US to improve its F-35 fleet. I’d go with GE engines, a slightly longer F-35 making room for longer range missiles and if add a new F-35 with two man crew. The two man crew would be hugely beneficial for ECM/EW and controlling large numbers of unmanned assets. If we made it a priority we could start production on these new improved F-35’s in a couple of years. This would complement the NGEN fighters that will arrive about the same time.

Add those improvements to the adaptive cycle and the NGAD will be 10x better

You are totally on-point. I only want everyone to see the difference between the original B-52 engine and the current one.

@@unclefart5527 EXACTLY.

Agreed, this has been mentioned somewhere else (don't quite remember but it might've been Tog himself) but research has been underway for some time on ceramic coatings. I wonder about the weight a bit but it should see the heating issue completely gone; in any case it only happened once in testing for some unknown reason

There’s the slight issue that if you run out of fuel the plane’s computers will fry themselves

@@asherwiggin6456 The plane will automatically shut off unnecessary systems in event of an emergency like running out of fuel, and in either case at that point you have bigger problems to worry about...like gliding safely to land

@@forzaelite1248 won’t it still fry the flight control systems so that you can’t control the plane?

@@asherwiggin6456 No, the flight controls are electrically actuated and air cooled since they don't generate enough heat to warrant liquid cooling; they'll work even if the engine cuts out. You'll never really hear of the controls in other fighters frying for any reason either because of this. The other systems onboard like the radar and the IR systems are what require cooling since they're always on

However, especially naval variant (C) could benefit from GE engine. Range is being constant issue with carrier based aircraft.

I vehemently disagree. We have had adaptive cycle technology since the ATF program with the GE YF120, which was also turned down if favor of the technologically inferior PW YF119, which the F135 is derived from. The F-35 is going to be our staple fighter for the better part of the century, and we cant keep chasing menial upgrades from an obsolete engine. The F135 ECU is insufficient even now. Additionally, the PW XA101 is untested. I dont even think PW is driven enough to do it. The XA100 on the other, is tested, and ready for service, and I believe it will replace the F135. The additional cost is worth it. It's long time to drop PW from the F-35 program.

Which is why DD would need to operate centrifugally, not linearly. But I suppose that would make it difficult to sustain the unit for very long.

@@TylerF35A Those are some bold claims. Having personally supported XA101 testing, I respectfully disagree. The team I worked with had some of the most exceptional and world class engineers.

@@Y13A what about the GE engine? their promo material states that's almost ready for production, is that too optimistic?

That's probably just slush money. You give engine upgrade funds to PW, GE, Rolls, etc, not the Airframe Manufacturers.

Yeah I mean the F35 engine is sick. It’s slightly larger than the F22 engine. But doesn’t have thrust vectoring. So you can imagine that they could easily modify the F35 engine to have thrust vectoring and slap 2 of them in a new fighter. You’re talking about 100,000lbs of thrust. With lighter carbon fiber materials smaller aim120s and just overall smaller and lighter electronics and all. You figure the new fighter the jet will damn near have a 2-1 thrust weight ratio armed. The F-22 is 65,000lbs loaded. We’ll see. But I think it’ll depend how which jet it is. The Air Force I imagine is going to make more of an Air space denial jet. That can loiter for long periods of time and has such good sensors and weapons that anything within a couple hundred miles of it will be blown out the sky. Where I’d imagine the navy would have more of an interceptor and agile plane to fend off missile and J-20 attacks on the carrier fleet and then have drone wingmen to carry out strike missions on ground targets. But yeah. China and Russia still haven’t fully developed the engines that were supposed to go into the J-20 and SU57. So we’re pretty far ahead of them on building engines. Japan wanted to build a stealth fighter for awhile now but they were smart and understood that the engine is essential to the stealth capabilities of the aircraft. So they’ve been working on their engine for awhile now. Haven’t heard anything recently though.

OK but let that tech flow down to the F-35 and possibly other planes as well.

@@forfun6273 Your ignorance is going to be your death forfun!

not sure why he is using Australia MQ28A Ghost Bat drone in NGAD and saying the engine could go in to them. is 100% up to Australia is those drones get them as is Australian drone solely made and sold in Australia as a sovereign product.

I wonder where the cams are on the jet?

@@Harley-D-Mcdonald in the head, obviously! I bet it comes with adjustable cam-gears straight from the factory.

That’s a great analogy.

“My AETP goes BWAAAAH” lmao

@@joshy9464 LOL!!

Which means they're not stealth on a modern battlefield.

You mean the radar and microwave spectrum instead of electromagnetic spectrum since Infrared is an electromagnetic wave also. Look up electromagnetic spectrum. Also a good IRST system can see the entire aircraft and not just the engine.

Main stream is a propaganda machine. Don't believe a word they say now.

it's technically sensitive info..soooo...nobody spoda know

Probably to avoid program delays and keep the development of technology moving. Worst case scenario they fit the new hardware and limit the software to the cooling requirements until more cooling is available, but better to have it in there and waiting for the green light update. There is also that these engines may also be used on NGAD which is still in development so they'll need extra time as well.

True, but probably you can bet that software will create most of the delays in the end.

You are missing the politics behind F35 acquisition decisions

He's referring to "Adaptive Cycle Engines"

You have doors which shunts air to the turbo fan just like on an airliner instead of ramming it through the engine core. This gives superior sub sonic range at cruise and your supersonic performance.

Marines will never be limited by our Equipment; the single Marine has always been our GREATEST Weapon.

@@devobronc My penis is the GREATEST Weapon. No equipment needed.

right 😅😂

I think NGAD will have new materials that will allow it substation very high speeds. I wonder if it is possible to ever but those coatings on future f35s, or if that’s too much of a change

Sustain*

honestly, RAM coatings should just be optional for specific missions, most missions dont really need stealth unless it's a REALLY high value target they're destroying

For reasons that should be obvious I can’t say much but I can tell you this is false. If you were speaking of the F-22 you’d be pretty close but the F-35 coating is a whole new animal.

@@ryankubinski8789 NGAD is only a pipe dream now, and if war was today, NGAD is irrelevant.

Budget allowing, If they add fresh double sided sticky tape before each flight to the upper surfaces this idea has merit.

ah, kinda like the buddy tanking F/A-18s. They didn't build them with enough range, so you have one fly as a gas can for the other so it can get to where it needs to go. As a bonus, you get additional flight hours on an airframe with no additional benefit towards completing the mission and your availability rate falls to below 50%.

Because idiot host stated something really stupid at the end. Disregard what he said as it is pure bunk.

It may be a capacity issue, RR will developing a new engine for the FCAS.

@@bernadmanny RR has no engine in the same class. Would have to start from scratch. Not saying they could not create one, just they have nothing to start from. The engine in F35 or potentially in it has its origins in the F15/F14 from the early 1970's. USA has settled on a ~48" diameter engine instead of the ~1m class engine. Namely as it allows higher Bypass ratio

Just a reminder --- Every fighter goes through engine upgrades. By example, the F15 was introduced with P&W engines. Once they matured, they let the F16 depend on a single one of them. Then GE won a competition to supply engines for the fleets. And it saved the USAF a lot of $$$$$$.

You need to get smart and join Australia as a small population with lower economy we developed MQ28 Ghost Bat to maximise our forces and have a cheap drone if need to use them as 1 way suicide bombers or take the hits while our crewed platforms escape or finish their mission. Got AI drone subs now also. ex patrol boat going AI to test surface vessel.

Second that. Not much commonality anyway. TBH I'd dump A altogether and have AF fly stripped down C airframe.

Thank you and thanks for being a channel member, my 4th was great, here's hoping that yours was too - know you know!

Aerodynamic drag is proportional to velocity squared. A 20% increase in speed will require a 40% increase in thrust. F35 has very unfortunate aerodynamic drag. It will NEVER perform as well as 4th gen fighters at high speed.

Thank you! And apologies where is AT?

@@PilotPhotog Austria 😁

not really precise as he uses Australia MQ28 Ghost Bat in the NGAD programme to get these new engines. Actually is up to Australia and Australia only if anything changes on our drone. Even the secret detachable nose design will only ever be done in Australia keeping the tech sovereign . All said by RAAF Commander head of the programme.

On the A-4 Skyhawks that I used to work on, the cockpit air conditioning system used engine bleed air as the input. My hazy understanding is that there was a simple chamber where the air spiraled and somehow separated out into hot and cold parts. The cold air was used to cool the pilot, and the hot air was dumped overboard. No idea if this is still used or not, but it was certainly a novel technique. Peltier devices are pretty handy, but fairly inefficient.

The problem would then be how you cool the hot side, and peltiers use more power.

That would be badass

If you toss in the RAM coating, it would be the most impressive jet in the world, full stop. It would also be incredibly expensive to design, test, restart production, and build them as all the F-22 product lines ended over 10 years ago. And the US and Japan considered it, but it was too expensive when F-35 exists, and they can put that development money into 6th gen fighters. Is it tragic the F-22 was so low production? Yep. Is it tragic the F-22 wasn't made modular enough to be able to update? Yep. It's my favorite jet, but we won't see more of it made.

You get NGAD

The Irony is that it’s actually cheaper to upgrade the avionics in the F-22 that the whole engine of f-35, they’re just better off off using the lessons of the almost disastrous clunky program of F-35 Lemon and designing a new plane to better integrate the new engine still have a things the f-35 do good while actually making it more stealthy, it’s not as stealthy as the the SU-57 let alone the F-22

F22 needs large fuel tank, the combat range very short. But if larger the tank, the stealh will be missing....

Just a reminder --- Every fighter goes through engine upgrades. By example, the F15 was introduced with P&W engines. Once they matured, they let the F16 depend on a single one of them. Then GE won a competition to supply engines for the fleets.

So..... NO supercruise??? Or when it does, bits of aircraft come flying off? I don't think your information is correct...

There is a different solution, I believe, a new Rolls Roys engine, that is being designed for the Tempest uses it: use excessive heat from the electronics and stuff to preheat air, just before it enters the combustion chamber, thus the engine becomes even more efficient, without producing any unnecessary heat

As is said in this video, for cooling is used bleed air from engine. Probably that air after cooling electronics is directed to the engine nozzle. Given temperatures of exhaust gases another couple kW is next to nothing. Jet engines uses power in MW so much much more than kWts

@@solarissv777 "use excessive heat from the electronics and stuff to preheat air, just before it enters the combustion chamber, thus the engine becomes even more efficient, without producing any unnecessary heat" Very unlikely that they would be injecting any preheated air from electronics cooling just upstream of the combustion chamber as you're thinking for a number of reasons. Air coming out of the high compressor is going to be around 900F or higher, good luck finding electronics that can operate hot enough to heat cooling flow up to those temperatures. Air going into the combustor also needs to be pressurized to the same or higher than what is coming out of the high compressor, at best you would have to reinject flow in the late stages of the high compressor, but that introduces compressor stability issues. Jet engines are actually less efficient as inlet temperature to the engine/combustor inlet increases; it's increases in turbine inlet temperature that improve efficiency.

Sounds like you work for P/W. ...or more likely have no idea what you're talking about.

@devobronc You always so thinned skinned and weak?

This is the truth. The F35 program is too massive at this point to clear all the hurdles required to bring an entirely new kind of engine into the mix. This video covers just about all of the pitfalls. That and the fact that PW’s engine is proven and reliable counts for something. This video doesn’t spend enough time on this point IMO. If the new PW engine will satisfy the cooling and energy demand needs of the F35 for the next >20 years, then leave it at that. Dont bite off more than you can chew. The F35 is a single engine plane, it shouldn’t serve as a testbed for an entirely new generation of engines midway through its production run. The entire NATO alliance is in the process of replacing their 50 year old planes with F35, they cannot afford delays and certainly cannot afford a resurgence of the political nightmare associated with the F35s procurement and development history starting at the beginning until just a couple years ago. Give it 20 years and sure, we can always upgrade the F35s then. After we know we can count on it. As a Canadian, get me those F35s without a headline about engine troubles. Not a good headline for cheap military spenders that have a massive arctic region to patrol with no emergency landing spots anywhere.

​@@devobroncHe's got a point tbh, looking at even the GE engine development it took some $6B to come to the conclusion that it is possible but not for all variants and would require another $6B in development before fitting and operational troubles. It was also rumored to potentially be an extra ton in weight; the technology is a little early in its existence at this point. NGAD's engines should provide a platform to develop the technology to make it lighter, easier to maintain, cheaper, etc. but for now cooling is the main issue and the ECU is the closer answer. Who knows, if we're lucky they crack open the budget dam and fund both at the same time for maximum cooling and power.

Working with totally green aircraft is very much still in its infancy. And for high speed and high performance right now, battery and solar simply don't cut it yet. In fact, they're not yet suitable for large and powerful commercial craft now. Best you can do is to make these things more efficient with what you have now. Don't get me wrong, we've made leaps and bounds when it comes to research on more renewable means of power and creating renewable fuels. Especially with vehicles that are far more common and are used far more in our daily lives but at the moment we just aren't there yet. Besides since you mentioned Elon Musk, you have to know his rockets require some fossil fuels to get up into orbit because it just won't cut it to use battery.

because things can't *just* happen, especially when talking about an entire fleet of very expensive things.

The F-15 is about 50 years old and still being manufactured. The F-35 is built to last 4 decades. How many WW2 fighters were still front line five years after WW2?

The F16 blk 50 and blk 52 both have different engines and are both currently used by the airforce.

@@Rob_F8F I think you missed the point mate. What he is saying is that there were many airplanes and within one model there were advancements made each year.

The engines aren't obsolete, if anything the fact that they can be reliably overrun without damaging them permanently or causing random engine failures is a testament to them being bulletproof like most turbine engines are nowadays. The F15 does not just "work". Its legacy as an air superiority platform is unmatched, but also because it fought against substantially inferior aircraft like the Mig 21, 23, and 29. You can't expect to take it into a 5th gen arena with even more powerful and smarter radars, IR systems, stealth, etc. and expect to just perform the same way. If we kept thinking this way we'd still be flying P-51s assuming we'd be alive at all.
