Well Maou if Rosver keeps wanting me to respond with answers no demon should know the answer to, you might be able to figure Rupert out…
Hint hint.
I think the misunderstanding with what I am saying and you are saying Rosver is “what exactly is the boom” what is the “force, and what is it acting against” in terms of Newton’s third law. F=dp/dt = dm/dt+dv/dt and most people forget the dm/dt part.
If you want to talk an explosion/boom, then I would argue the boom that makes a [i]rocket[/i] go vs a jet, then I’d be more amenable to that. A rocket works in space by transforming the mass of it’s fuel into a gas and then expelling it in a directed manner. However, it is also the dm/dt that’s happening here, so it literally is the explosion (or more precisely the conversion and expelling of the gas)driving the rocket. But both are “pressure booms” in a way.
The boom is the gas pressure change and expelling of gas in a directed manner, not the fire or pyromancy part. All the pyromancy is doing is changing a liquid or solid to a gaseous state that takes up more space, thus creating a high pressure region (which is what’s doing the pushing)
In the case of the jet, the turbine is sucking air into the combustion chamber, combining it with jet fuel, converting the liqued fuel to a vry hot gas. Thus in the combustion chamber you now have a very hot (hotter gas==higher pressure) that seeks equilibrium and rushes out the exhaust expanding into a lower pressure region, basically you are creating a small high pressure region at the end of the engine that’s pushing the plane forward as the gas heads the other way to the lower pressure region. That’s Newton’s third law, it’s the quickly changing gas pressure pushing the jet.
What I am saying in all of this is that there are other ways to change gas pressure and cause a carpet or other item to go than just combustion. Aeromastery is the literal direct manipulation of gases with mana.
And Maou is correct in what he’s saying about most efficient design, the air shields are uniform and relatively solid and nicely shaped, like an aerodynamic car. Thus you can create a nice airflow over the top of the carpet, if you design the shield properly, then you can even reduce air pressure on top and increase lift. The key to an airplane wing is that you want the air on top of the wing to move faster than the air under the wing. Given that the true overall velocity of the carpet is fixed, if you require the air on top of the wing to travel a greater distance than the air under the wing, it “travels further” in the same time and thus creates a lower pressure region and lifts the carpet by sucking it up.
So of course, part of Maou’s question is: how the hell do they know this? Well a lot of trial and error, but more importantly aeromancers can sense and manipulate the air directly, something Earth scientists can’t do. Thus creating wind tunnels and other simulators for practice and very direct observation is much easier in Astlan.
As to tutoring? Who’s he going to ask without revealing himself? That will be tricky. Also, having time to sit down and study will be hard to come by…but I am sure that will be his plan once he gets time to create a plan.
I think Jenn is concerned about Rupert because he’s a kid, she was basically in charge of the kids and Rupert is/has been an oddball that requires more attention. Particularly lately. Remember Trisfelt took the other kids to safety and so she was left protecting just Rupert, who was not making it easy for her.
Half demons are evil too. Clearly.
