That's what I said above. lol

By the way, Suite has nothing to do with thrust really. It can either be Suite 2 or Suite 8, engine is going to be the same.

Engines underpowered David, That data is from Real life. We aren't talking about real life here, we are talking about DCS. We don't want to find out the thrust of the TF34 in real life, the people that are asking and discussing the topic want to know how the TF34 is performing IN DCS, not real life. If you want to find out the thrust in DCS, you'd use the dev tools. We don't have access, that's why this discussion always comes up once in a while. We simply can not jump into the game, do some math and done, you have the thrust of the TF34. Yo-Yo said the engine in DCS meets GE charts, I'm fine with that. But what if you wanted to find out the thrust yourself? That's what I was trying to say. Let's forget the documents for a moment, please. Regarding the other topic; It DEPENDS. Generally speaking, there are two types of maintenance, the one that is done on the flight line, and the one in the shop. But you're right. They don't always test the thrust. But they do test other parameters which can give you an idea of the engine's health. Therefore you can estimate the thrust by using the data. On the flight line, you'd be doing the basic maintenance of the aircraft and engine, such as fluid cleaning, FOD, erosion inspections, basic repairs, changing parts of the engine and so on. Since this kind of operation needs a special care, sending the engine to a proper facility might be the best thing to do, in case the inspection on the flight line detects FOD and erosion damages for example. Damages to the compressor and turbine rotors will affect engine's performance. Obviously, it depends on the damage itself, but when a greater change in geometry of the turbine/compressor rotor blades occur, this can degrade the performance and cause malfunctions. Which results in lack of compression ratio, lower/greater ITT, loss of turbine efficiency (which is pretty normal actually, unless beyond normal conditions) and others. Then, the engine must go to a facility. But on the flight line, you can still do repair and other things while the engine is mounted on the airframe. In the shop is where they do the heavy duty stuff. Since they have special tools, they can remove the turbine rotor assembly, compressor etc. After all the troubleshooting, repair, replacement is done, they test the engine, and thrust is included. But before they must check if the gauges are calibrated. Otherwise, the info on the display would be meaningless (And this happened in the AgentJayZ shop, watch his last videos and you'll see [emoji3]) Anyway, here's an example of how it's done.

Engines underpowered To calculate the in-game thrust? I was actually replying Dakota. If we had these numbers, we would be able to calculate the in-game thrust. People say the TF34 in DCS is underpowered because that Hawg pilot said so. I was just saying that if we could have proper ways to calculate the thrust, we wouldn't see these discussions anymore. About the engine being out of the jet, that's not entirely correct. When they test the engine, they always check the parameters, and if it meets specific conditions, it can get back to the jet. It's not that simple.
-
Yes we can in fact fly by the numbers. But we still can't calculate the thrust. We don't have the proper tools. Simple formula which would probably give an end to this discussion is Mass*V1-V2/G. But we don't have the necessary information to supply this formula with the numbers. And I don't think Yo-Yo is going to give us those numbers.

We need to call SecureTeam10! :D

ME-163B by Komet Simulations
Vitormouraa replied to razo+r's topic in Flyable/Drivable Mods for DCS World
Those would be the fuel cells. Such as hydrogen and oxidizer. For instance, the Me-163 uses hydrazine, same as the F-16 (Used to start the EPU). -

For your information, rocket is a jet engine. Me-163 is a jet-powered aircraft. -

This is the maximum ITT you can achieve in the sim currently. During the startup the ITT can spike to 900°C (although I've never seen it myself), but the limit is 865°C. IIRC we can't achieve rated ITT however.
-
Keep in mind that Matt and other ED members are in Moscow at the moment, so you may not see anything for a while. ED's CEO unfortunately passed away a few weeks ago, so I'd give them some time to organize the things. We need to be patient, it's coming for sure.
-
That's way beyond the operational limit. Maximum ITT is 865°C. But then again, a higher ITT doesn't necessarily mean a higher thrust.
-
Are you serious? You are the one saying jet fuel can't be atomized. This must be a joke. Unbelievable. You said I believe in false theories, which is far from being true. I think the only person here who believes in such a thing is you. First thing I do when I quote someone on the subject is, I open the books I use to study and I make sure I am not sharing wrong information. I am sorry but this is getting ridiculous.
-
Like this? :) https://vimeo.com/93790719#t=115s This is called filler and it's very cool! You can also use the immortal option for training, although it's not realistic. But I agree on that, a special belt with filler would be nice.
-
Exactly! You answered yourself buddy, when the MiG-29 collided with the other, Fuel was dumped into the atmosphere as vapor. If it was in liquid state, it wouldn't burn. I'm not disagreeing with you about that. Fuel will burn if it's atomized/vaporized. :)
-
The mist you're talking about is what makes the fuel burn :megalol: The fuel in liquid state simply won't burn, that's why it's atomized. Vapor burns, liquid does not. It's not about believing in false theories. It's science. GE, PW and RR, all those companies were all the whole time, right? Jet-A can't be atomized? LOL!
-
Is this some sort of joke?
-
It could but there is a limited amount of fuel being sprayed, even if it ignites it will burn very quickly. The planes are also flying at a considerable speed, maintaining a stable flame wouldn't be easy. If the fuel goes into the engine, that's not a problem. There is a video of an E-3 being refueled and the boom was negative charged due to the air friction. You could literally see a spark between the E-3 fuselage and the boom. The boom leaked fuel and nothing bad happened there.

It's not about the engineers, it's about this thread specifically. Some of your explanations aren't correct. Liquid fuel does not burn, it can't be burnt. That's why the fuel is atomized before igniting. This process is known as atomization or vaporization. In a medium-sized engine to a large turbofan, we would be talking about hundreds of psi. From 800 to 1500 psi in this process of atomization. Fuel must be sprayed into a nozzle under very high pressure, even then, the spray pattern must meet specific patterns because if not, the flame may touch the combustion walls, causing hotspot or even cut thru the metal. There is a lot more to that such as energy release from the flame. An incorrect or disproportional ratio of air and fuel may result in waste. This can increase flame length, especially during the startup or when the engine is operating at lower compression ratios. It's not just about heat and fuel. Light up a match and throw the burning match into a tank full of JetA, the fire will go out. When the fuel is in a liquid state it won't be a problem, but when its vaporized, an ignition depending on the conditions, is very likely.

This thread is nothing but funny. :) F-15 is a very tough plane, that's for sure. But IMHO it's clear how the F-15 has issues with damage model in DCS. Something that ED/BST needs to look at.
