RE: F-22 Loadout

Post by ComDev »

ORIGINAL:  Wiz33

So we use whatever open source info available:

This is for the F-35 but we can infer that the F-22 would only do better:

This is from Air Force magazine.

The F-35, while not technically a "supercruising" aircraft, can maintain Mach 1.2 for a dash of 150 miles without using fuel-gulping afterburners.
"Mach 1.2 is a good speed for you, according to the pilots," O’Bryan said.
The high speed also allows the F-35 to impart more energy to a weapon such as a bomb or missile, meaning the aircraft will be able to "throw" such munitions farther than they could go on their own energy alone.
There is a major extension of the fighter’s range if speed is kept around Mach .9, O’Bryan went on, but he asserted that F-35 transonic performance is exceptional and goes "through the [Mach 1] number fairly easily." The transonic area is "where you really operate."

Thanks for the info [8D] There is quite a lot of info available on these planes already so no need to spy. And physical laws still apply, even for 5th gen fighters, which makes guessimating the missing stats possible as well.

I'm a bit curious what the difference is between the info you posted and what I wrote above. Mach 1.0 at 36k ft is ca 570kt so a Mach 0.9 cruise speed is 515-ish knots. In other words what we're discussing here is the 35kt difference, i.e. whether the cruise speed of the F-35 should be 480kt or 515kt?

Since most modern fighters have a 480kt cruise speed in the Command database it would make things easier for the player (and the AI!) to organize strike packages using identical cruise speeds. Something I feel is more important than those 35kt, as per our two decades long experience with Harpoon.

And we do not know if the cruise speed is _exactly_ Mach 0.9. It could be Mach 0.87 which is 495kt, a 15kt difference.

Anyway guys let me know what you think. The good thing about Command is that nothing in carved in stone and we can make whatever changes we want when it makes sense to do so [8D]
In combat configuration, the F-35’s range exceeds that of fourth generation fighters by 25 percent. These are Air Force figures, O’Bryan noted. "We’re comparing [the F-35] to [the] ‘best of’ fourth gen" fighters. The F-35 "compares favorably in any area of the envelope," he asserted.

Other source say that It can hit Mach .9 at 80% throttle.

Yeah that's 'cruise'. Supersonic at 100% throttle is 'supercruise'. Which is also the case in the Command database.
One thing that most people is confused about is that only modern planes can cruise above Mach 1 without afterburner but that is not true. While the F-22 is the first that can supercruise at above Mach 1.5 without burner. Planes as old as the British Lightning II can go above Mach 1 on dry thrust also. In fact. The french Rafale can go over Mach 1 with external stores on dry thrust.

Yes operating at 100% throttle will have a impact on operational range as it has been stated that a 100 mile dash at supercruise will result in a 150nm range reduction on the F-22. But if the F-35 can do Mach .9 at 80% throttle and was meant to fly at that speed most of the time. The F-22 should be able to do the same or better.

Basically. The game as it currently stands makes all modern aircraft cruise at the same speed which is just not true for the 5th generation aircraft with no external stores.

F-15C in clean config with newer engines can supercruise at Mach 1.1 as well. Rafale and Eurofighter supposedly has a Mach 1.3 supercruise (also in Command!), F-14B/D supposedly Mach 1.05-ish clean also. Once you start adding stores things change dramatically though.

While you're talking about airspeeds, what kind of airspeed is the one that is indicated in CMANO? True airspeed, indicated airspeed, ground speed? Is a plane flying 480 knots at 200ft in CMANO going the same speed as one flying 480kt at 40.000ft?

I think 480 is probably fine.

An F-16A can maintain about .9 on 80% throttle too, as long as its clean. A small statement like that is not enough to go on I think because there are so many variables. And even if it does have higher cruise speed, as Ragnar says it's hardly going to be that much more. I say keep it as it is now.

But it would be cool to confirm what kind of speed it is. TAS I would guess?

We're using true airspeed. We don't have wind in Command and as such true airspeed = groundspeed.

I guess my point is that there should be a noticeable difference in cruise speed between a Gen 4/4.5 aircraft with external stores and a Gen 5 aircraft with internal stores even at a fuel efficient throttle setting. If the F-35 (which is not design to supercruise) can do Mach .9 with fuel efficiency. Then a F-22/T-50 should be able to do over Mach 1 at the same throttle setting. I know it's a commercial aircraft but the Concorde may be a good example as it use AB to quickly punch thru Mach 1 and then throttle back for the long cruise.

But that would assume that all aircraft in the game consume the same amount of fuel at "full" speed setting. Is that even the case, or is the fuel efficiency at a particular throttle setting different between platforms?

OK. I may have phrase it wrong when I say throttle setting. How about this:

Then a F-22/T-50 (with an airframe designed for supercruise) should be able to cruise at over Mach 1 at a fuel efficiency setting. I know it's a commercial aircraft but the Concorde may be a good example as it use AB to quickly punch thru Mach 1 and then throttle back for the long cruise.

The point I was trying to make is: I think the "throttle" in CMANO that can be accessed by pressing F2 is not really a throttle representing a fuel efficiency rating, but rather a speed setting. Because when you go to "full" for example, the speed will be the same at sea level as it is at high altitude, while the fuel efficiency will be different.

Cruise at Mach 1+ is per definition not fuel efficient. High subsonic gives by far the longest range. In addition to giving the best possible combat range, the 'cruise throttle' setting in Command is also used for ferry flights [:)]

So for the F-22/35 you can either cruise at the most efficient speed setting of ca Mach 0.85, or you can supercruise at Mach 1.65.

In the upcoming Speed/Altitude selection window that I'm working on you can manually enter the speed, and thus select the exact speed for your planes. So if you want fly at Mach 1.2 you can do that no problem, but fuel burn rates will be higher, as they would in real life.

efficiency

Fuel burn rate calculations in Command are a bit complex.

We use static thrust and specific fuel consumption as a base, and then apply a bunch of factors. I'll check the code and post up some details. There have been a couple requests for engine details in the DBViewer so might add that too once I've finished the 50+ other things I'm currently working on.

Thanks! [8D]

I hate it when developers beat around the bushes instead of being honest! I couldn't understand why you guys have such resistance on the idea that the F-22/T-50 would cruise at a noticeable higher speed than other planes laden with external stores. Then I read this thread:

tm.asp?m=3448328

It took a bunch of messages and peoples quoting all kind of stats to finally get the Devs to admit that the reason all planes fly at 40K is because the game is not currently using individual flight profile for each aircraft/mission type and 40K was a placeholder. But that feature will be implemented in the future.

That got me thinking and I went and look at the DB.3 files for aircraft. Now I understand. There are no individual aircraft flight speed at loiter, cruise or full. The only data in the propulsion file is the top speed of every aircraft. While there might be a different speed set for each aircraft type (helo, prop, jet, etc), all aircraft of a similar type flies at the same speed except at max.

Which bring me back to the first line of this message. The Devs should know that most people that like this kind of game have some knowledge of the subject (not to brag but my name was in the acknowledgement in the Harpoon Battlebook) and knows where to dig for information (including hacking/looking through the database) and that someone would eventually figure out the truth. The truth is that as the current database stands, you cannot give the F-22/T-50 a higher cruising speed (they might if they give it a different category number with their own speed set).

Why didn't they come out and say that. I know that CMANO is a extremely complex game and it's a tremendous achievement for a very small team. With so much work to be done, something may get pushed back for a future update. I would have understand, just like on the other thread. Once the evasion ends and the truth is out. everyone is fine with the 40K placeholder knowing that it will be fixed at some point.

To the developers. I love the game. It gives me 95% of what I think all the earlier games is missing in one aspect or another. I have no problem with some minor features not working 100% yet but please don't be evasive to our questions. If it cannot be done in the game as it stands. Tell us the reason so and we will understand (especially if it's marked for a future improvement).

Hi Wiz,

I think Ragnar laid out what he needs and his flexiblity.:
Thanks for the info There is quite a lot of info available on these planes already so no need to spy. And physical laws still apply, even for 5th gen fighters, which makes guessimating the missing stats possible as well.

I'm a bit curious what the difference is between the info you posted and what I wrote above. Mach 1.0 at 36k ft is ca 570kt so a Mach 0.9 cruise speed is 515-ish knots. In other words what we're discussing here is the 35kt difference, i.e. whether the cruise speed of the F-35 should be 480kt or 515kt?

Anyway guys let me know what you think. The good thing about Command is that nothing in carved in stone and we can make whatever changes we want when it makes sense to do so

Are you sure?

I'm not saying everything is necessarily peachy, and it's worth looking into fuel burn etc. But I am more inclined to believe the devs are hesitant because there is only statements out there about capabilities that may be ambiguous and are hard to verify.

At the same time, in my opinion, I dont know if an F-35 really is going to cruise faster than my F-16. While normally "Because I can" is a 100% valid argument, in this case I'm not sure. The higher speed and supercruise is great to use in tactical scenarios, but just while cruising it is more common to see various participants in a mission choose the same ingress speed, so that you can talk in timings easily as well.

And in addition, you can already manually set the higher speed if you want. And once waypoint editing comes in thatll be even easier.

This doesnt mean that we dont have to look into fuel consumption because there might certainly be imperfections with that too.

I just dont think the devs are purposely trying to lie or whatever, I think they want the most accurate sim they can get but are hesitant to make changes based on incomplete info and want to be careful to look at it thoroughly before making changes rashly.

Just my two cents. And I think in the end we all want the same thing, for Command to be the best and the most accurate that it can be

I think they have aircraft grouped into types or have a bunch od speed setting sets as all you can find in the Database is the max speed. Any aircraft will fly faster while using less fuel in a clean config. So why is it so hard to understand that there should be a noticeable speed difference between a F-15 fully laden with external stores (even just AAM and tanks) vs a F-22 with internal carriage. Either one of them is going too fast or the other is going too slow. Simple as that.

I just did a test. Took a F-22 with internals only and an F-15C with tanks and AAMs and put them both at 40k feet and 480 knots. The fuel quantity of course is different with the tanks on the F-15. But the fuel being burned, and the "kg remaining" counting down seems to be the same. The F-22 does not seem to be more fuel efficient at the same speed than the F-15C.

SFC for the F-22 is actually higher than for the F-15C ;)

I suggest that there should be one DB entry for an F-22 Clean, no pylons, and one entry for one with pylons. Speed, agility, fuel consumption and RCS should be different. This should apply to other stealth A/C that suffer so big difference in game play.

As it is now, i only load them with internal load.

Or just add a penalty % for each loadout. Which would apply to both the cruise speed and agility rating until the stores are used up or jettisoned (excluing AAM).

Okay been putting together this one from screenshots from the database editor. It gives some clues about what's going on under the hood.

Real sorry for taking so long to get back to you on this, coding like crazy on this end and doing database updates in between.

Thanks! [8D]
