[OOC: You're not going to get a bomber with a payload of 80,000 lbs to fly at Mach 2 or 3, without some sort of SCRAMjet engine, which of course presents it's own problems - for one, SCRAMjet doesn't work in the lower atmosphere because the air is too thick. It is to say, they haven't gotten a SCRAMjet aircraft to either take off, or to land. Consequently, you're going to have to reduce your payload, or you're going to have to reduce your speed. Regardless, speed is really a necessity, as much as payload is - well, that's in my own tactical doctrine. Ok, I'll go away now.]

Not exactly. He can get a Mach 3 with that. He just needs powerful enough engines. Most bombers in NS can produce over 80,000 lbs of thrust per engine. He can use weaker engines rated at 60,000 lbs of thrust per engine and still get the job done.

Also don't use SCRAMjet. Those things are horrible unless your trying to go hypersonic. They are a real gas guzzlers. They consumer more than they are worth.

[OOC: Well, most bombers in NS have turbofans that produce over 80,000 lbs of thrust because most designers don't understand squat about engines, and especially about turboprops or turbojets or turbofans.

In fact, if you're turboprop is producing around 80,000 lbs of thrust you're chewing more gas than a SCRAMjet engine would, which contrary to what you think, aren't that bad when consuming on board gasoline - especially since they carry at least twice the load of a normal engine. Regardless, you don't want to use a SCRAMjet engine on an aircraft anyways.

Most modern engineers are focusing away from producing more thrust, because more thrust needs more fuel, and the engine would weight two times as much, increasing drag. So, it's the common, the larger, not better. Right now they're focusing on fuel conservation systems, including chaning the turbofan's blade system, which has come out with the turboprop experimentation. ]

Im not a expert on jets and stuff but couldnt you fit the bombar with a SCRAMjet engine and a small engine for taking off and manuvering in low altitudes?

That is an answer, but that requires two engines with seperate mechanics. You would probably use a single, large, engine on the tail of the bomber, or just under, to accelerate the aircraft so that it can take off and rise in altitude to the required height for a SCRAMjet engine to work.

However, that just subtracts from the idea of SCRAMjet, because you would still need an oxygen chamber for the main engine, and you would still need a seperate fuel supply for that, and that, indeed, would be gas guzzler.

The only bomber I have with a SCRAMjet engine is my Naram Sin, and that's designed to be refueld by air, and it does eat gas like an SUV (metaphor, it actually sucks more).

So, in short, it wouldn't be cost effective.

29-08-2005, 04:09
Actually, it is indeed possible for a Mach 2+ bomber to have more than 80,000lbs in its payload, just depending on its design. The B-1B for example, could haul much more than that if it's not for the arms reduction treaties (which prohibited external carriage of weapons), and it's speed reduction is primarily the result of efforts to reduce its RCS. It is indeed possible to have engines of very high thrust, but depends on what aircraft it is on. Larger engines, as said, eats up a lot of fuel, and takes up a lot of space, which will make carriage on smaller aircraft impossible. On larger aircraft, this problem is reduced, and large-thrust engines are indeed possible.

29-08-2005, 04:19
[OOC: Of what I've studies of thurst in physics, is that for the aircraft to successfully take off it would need more thrust than weight, in a healthy proportion. However, the engines required to give a thrust of 80,000lbs, would mean that the aircraft would have to be lower it's 80,000 lb weapon weight expectation, and the fact that the engines giving that thrust themselves weight tons a piece doesn't exactly help.

The largest turbofans I know of produce somewhere around 43,000 lbf. I for one, even if it was possible, wouldn't suggest putting engines with 80,000 lbs of thrust. It just doesn't seem cost effective, or really smart, to me.]

Well if you mean that the thrust has to be more than the weight to take off then I have to say your wrong. Yes there has to be a minimum thrust:weight ratio, but if we look at the SR-71, it's thrust/weight ratio is 0.382:1.

Also it is possible to make over 80,000 lbs. Of course you can't use a turbofan, but the use of PDE could do that and not be a gas guzzler because it theoratically has an efficiency of 50%, more than any other engine including turbofans.

Space Union:

Here's the lesson on thrust from Wikipedia; or at least the essential part for this discussion:


An aircraft generates forward thrust when the spinning propellers blow air, or eject expanding gases from a jet engine to the back of the aircraft. The forward thrust is proportional to the (mass of the air) multiplied by (average velocity of the airstream).

Similarly, a ship generates forward thrust (or reverse thrust) when the propellers are turned to accelerate water backwards (or forwards). The resulting thrust pushes the ship in the equal and opposite direction to the sum of the momentum change in the water flowing through the propeller.

A rocket (and all mass attached to it) is propelled forward by a thrust force equal to, and opposite of, the time-rate of momentum change experienced by the exhaust mass accelerating out from the combustion chamber through the rocket nozzle. This is the exhaust velocity with respect to the rocket, times the time-rate at which the mass is expelled. Of course, for a launch the thrust at lift-off should be more than the weight, and with a fair margin, because a "slow launch" would be very inefficient.


Illior:

Unfortunately, that engnes was created for a civilian aircraft, and it's being tested currently on the Boeing 747. The take off weight of a Boeing 747 is much lighter than a bomber designed to be about 1 and 1/2 the size of it, with an additional 80,000 lbs of weight worth of munitions, at two times the expected altitude of the 747, with more weight coming from the crew and all expected electronics.

If you were to use this engine I wouldn't expect it to cover more than the range from Lisbon to Warsaw without a substantial fuel supply, which would make it weigh even more.

So, for the case of NationStates, where distances exceed the distance from New York to Beijing, over Europe, I don't think this bomber would be extremely beneficial, especially since it wouldn't be able to take off from an aircraft carrier. Of course, for short range, heavy duty, bombings, I guess this bomber would be perfect.

The key word is efficient. Yes I never said that an aircraft with a thrust lower than it's weight would be efficient. I'm just saying that it can take-off. Look at the SR-71, from my experience it was able to take-off and then break Mach 3.

Fuel capacity isn't that big of a deal anymore. With NS, air forces have a huge complement of oil tankers that will refuel the aircraft and double it's range. It's not a problem anymore.

One more thing, sorry DMG, but I have to refute the claim that PDE engines are a good choice for a bomber.

The single largest problem with the PDE engine is that the PDE, currently, has not found a way to start a detonation early without making the energy imput practical for an engine.

Practically, they would look for a Deflagration-to-Detonation Transition (DDT), however, they can't find a tube long enough that makes it practical and less drag imposing on an aircraft.

Consequently, using a PDE on this aircraft is going to increase drag, and decrease effeciency.

-------------

What I would use to make this baby fly is a propfan type system, also known as an ultra-high bypass engine. It's designed to offer the power of a turbufan, but with extreme fuel efficiency, and is what I'm using in my current bomber project.

However, be careful, props have the problem of encountering increased drag at higher velocities, but you can subsidize that by adding more blades to the prop.

Quite a few aircrafts use PDE in NS. Soviet Bloc, Omz222, and I (Mish-11 and F-76) use PDE on some of our aircrafts.

I wouldn't say it is impratical to use them. Considering the NS technology is a decade ahead of real-world technology, I think PDE is very workable.

--------------------------------------------------------------------------

I did some research on that, and it won't fit his objective. From what I see a propfan is just a turbofan with propeller and fan combined that isn't ducted inside the engine.

They are relatively nosy compared to other aircrafts and they suffer the same issues as propeller aircrafts do (though cut by sweeping of the propeller similar to sweeping of the wings) as they have a speed limit and can't break the sound barrier.

Also adding propellers might solve the issue but it also brings others. Adding propellers causes the engine to use up more power at a lower rotational speed. Not only that but that adding blades makes the propeller harder to balance and maintain. And another problem is that at some point through the forward speed of the plane combined with the rotational speed of the propeller will once again result in wave drag problems. (The last point could be solved with sweeping of the propeller so don't worry about that).

Well then he's stuck with a normal turbofan, becuase I would consider PDEs post-modern technology, unless someone can explain to me how they jumped ten years and solved the problem of the PDE - I don't care if the PDE will be solved within ten years in the real world, but I need to know how, or simply, it doesn't work.

Technically, a 100% effective fusion reactor is due to work in the future - well, we can say that because we jump ahead, I can use fusion reactors on my tanks, because perhaps, due to so technological miracle, they'll work.

Consequently, PDEs fall under PMT, where it can't really be explained, and thus, it isn't a modern tech weapon.

Well considering that the there are problems with railgun and ETC technology that don't allow for them to be used on tanks yet, then you must not accept them either.

Exactly, rail guns are considered extreme post-modern tech; that's why my navy no longer employs them. ETC guns do not have the same visible problems that a rail gun or a PDE engine has, so it's a different case.

An ETC gun has also problems that don't allow it to be used on Real-life MBTs. It is heavier and can only be used a couple of times before wearing out. Not only that but they require a huge power supply that can't be delivered today by any powerplant that could fit inside of a real-life MBT. In NS we obviously have overcome these problems.

I have six of these units on the B-70B Valkyrie II and they perform very well. I was assuming he was planning on using more than two engines on this plane. If he wants to use two engines then most certainly he will have to look at the behemoth 777 or Airbus engines that GE designed.

If you read the spec on the page 4, I am using 6 GE-138 which give 41,300 lbs of thrust each. (GE-138 is the next generation after GE-136, especially developed for this bomber)

I'm not sure how your going to get range with that. Considering that your bomber has to be heavier than 192,000 lbs just empty and then you have to add all the fuel and then you have to add the 80,000 lbs of armenant, you'll find that just 6 might not do the job and get a decent range. Instead Why don't you use something that is in the 60,000 lbs per thrust class. That will do it. Also since your payload is near the B-1B (internal 75,000 lbs not including 59,000 lbs on hardpoint), you should just scale up the B-1B in terms of weight and thrust.

If DMG decides to not use the airframe you made in CAD, I would love to buy it from you to design a medium to long range bomber

TG me about it or something

What engines do you suggest then...?

OOC: :eek: i forgot about the XB-70! it would make a very good craft though we would need better engines for the 80K bomb load

[Um, the engines on the B-70 were already ridiculously powerful; you're talking plants that would have used boron-based high-energy fuels instead of hydrocarbons had the program been carried through to completion. In fact, it was utterly dependant on that program and could not have met it's range goals without them. The XB-70 would not make a very good craft; while it was certainly pretty, it's a big, unstealthy monster that's easy to intercept with 1960s technology, used too much cutting-edge technology for it's own good [Thomas S. Gates, Secretary of Defense during the last 2 years of the Eisenhower Administration, said explicitly that the B-70 program was hampered from the start by technical problems stemming from the "use of metal and components . . . still in the research stage."] and used fuel that would have been horrendously and probably unafforably expensive. The development of the ICBM and the surface-to-air missile were the end of the ultrafast aircraft projects, and rightly so.]

OOC: I know that is was unstealthy and that 1960 SAMs could take it out and i know it was expensive. i guess i didn't go into much detail on what i ment. would you like me to tell you, or would you like me to just shut up and save server space?
