Elon Musk revealed Why SpaceX Raptor 3 is Worse than Expected! New SpaceX Solution... 
The Raptor 3 has arrived, carrying with it high expectations. But is it perfect yet? Recently, problems seem to have emerged, especially after confirmation from Elon Musk. But the crazy goals remain. So what is happening with the Raptor 3? What crazy things is SpaceX aiming for with this engine version?
The main focus, of course, is the engines. This is the first time we have seen a complete lineup of Raptor 3 engines assembled like this. It is truly a sight to behold, looking less like a traditional rocket engine and more like something pulled out of a futuristic laboratory where the scientists have a healthy obsession with shiny, integrated components. But is it truly perfect? Or has it met SpaceX's expectations? 
Let’s find out on today’s episode of Great SpaceX.

Elon Musk proudly praised the appearance of the Raptor 3 engines on the B19. Then, an X account lauded the thrust that the Raptor 3 engines could generate. 
But surprisingly, Elon Musk made a rather modest revelation. Specifically, he said: Less thrust than that today. This means that in the B19 test attempt, although it may look very powerful, the 33 engines did not reach the maximum power of over 9200 tons of thrust as many expected. Why is that? In reality, even during testing or operation, the engine probably won't be pushed to its maximum power. The reported thrust usually comes from the results of individual engine tests. When combined, trying to push everything to the limit can overload the engine. Remember, during operation, the engine not only supports takeoff but will also be switched on and off many times afterward. It is like taking 33 highly caffeinated thoroughbred horses and trying to get them to pull a carriage in a perfectly synchronized line at a full gallop on their very first day together; something is bound to get a little messy. If you have ever tried to get a group of 33 friends to agree on where to go for dinner, you know that coordination is often harder than the actual task itself.

But what makes us suspicious is Elon Musk's seemingly pessimistic response. If less thrust is an obvious problem, why would he mention it here? So, this might be hinting at something else. A major question lies in the Raptor 3's turbopump. With a full-flow staged combustion cycle, both methane and liquid oxygen are passed through separate turbopumps at extremely high pressure before entering the combustion chamber. When thrust is increased, the rotational speed and mechanical load of the turbopump increase exponentially, leading to the risk of cavitation in a cryogenic environment. Cavitation is a nasty little phenomenon where bubbles form in the liquid because of the speed, and when they collapse, they can send shockwaves that eat through metal like it is made of wet sugar. Even the formation of tiny air bubbles in the liquid oxygen stream can cause vibrations, reduce flow, and destabilize the entire system. It is like trying to drink a thick milkshake through a very thin straw as fast as you possibly can; eventually, the physics just gives up and you get a brain freeze, but in a rocket engine, that brain freeze results in an explosion.
