Over the years I have lamented the incredibly slow technical development of rocket engines. Even today engines like the RL-10, AJ-10, RS-25, RD-180 that are results of technologies developed as early as the 1950s, are still in use. I was told by many that RL-10, for example, with its ISP of 465.5 seconds was the best that could ever be. I replied that it was as absurd as stating a 1957 Chevy was the pinnacle of automotive technology and could not be improved. Elon and his genius rocket engineers have shown what is possible. The Raptor 2 is levels more advanced in so many areas than anything else in the world. It gives me great confidence for humankind’s future in space seeing the extraordinary engineering work that is going on in SpaceX.

I only soft agree with this. While these engines are very advanced, they are still fundamentally fossil-burning motors. IMO if we are to truly advance to a solar system-wide civilization we need to figure out better propellants and better ways to derive thrust power. I'm not saying The Expanse-level torch drives, but at least something with better ISP than hydrogen. (no, current ion drives don't count because they have the thrust of a hummingbird) EDIT since it wasn't clear: the issue with fossil-burning motors isn't the fossil part, it's the burning part. Combustion-based rockets have garbage ISP.

Now that said instrumentation has given them a thorough understanding of the design's behavior, all of the instrumentation which is not absolutely required for feedback inputs to the control system is no longer necessary.

Liquid rocket operations don't naturally lend themselves to the concept as solids, and Musk was speaking of the top of his head. But even Super Heavy and Starship have a total impulse consideration. That is, they have limited propellant stocks, so there is a maximum total impulse each stage can provide. And to his salient point: specific impulse varies at least somewhat in any solid or liquid engine due to a variety of factors, particularly chamber pressure. Taking a total impulse value (e.g. Ns) and dividing by the *weight* of the propellant (e.g. N) gives you an average Isp in seconds over the interval.

Aerospike engines are a type of rocket engine design that offers certain advantages over traditional bell-shaped rocket nozzles. Instead of a bell-shaped nozzle, aerospike engines have a unique shape that resembles an inverted cone or spike, hence the name "aerospike." The key advantage of aerospike engines is their ability to maintain efficient thrust at a range of altitudes. Traditional bell-shaped nozzles are optimized for a specific altitude, resulting in decreased efficiency at other altitudes. In contrast, aerospike engines adapt to varying atmospheric pressure by automatically adjusting their nozzle shape, allowing them to maintain optimal performance over a wider range of altitudes. Aerospike engines work based on the principle of aerodynamic expansion. As the rocket ascends, the decreasing atmospheric pressure causes the exhaust gases to expand. The shape of the aerospike nozzle adjusts to match the changing pressure, ensuring that the exhaust gases are optimally expanded for efficient thrust. Another advantage of aerospike engines is their potential for weight savings. The design eliminates the need for a heavy and complex bell-shaped nozzle, reducing the overall weight of the engine. This weight reduction can lead to increased payload capacity or fuel efficiency. However, despite their advantages, aerospike engines have not yet been widely adopted for space missions. They present engineering challenges and complexities, and their performance benefits in real-world applications have not been fully realized. Nonetheless, aerospike engines remain an area of ongoing research and development in the field of rocket propulsion.

The Raptor engine is indeed an insane thing, such a big step forward. And 250 tons of thrust is simply amazing from something that size. My only concern is the start sequence, how difficult and critical it is. And when you need to start 33 of them at the same time there is no room for error. Also for landing, I hope starting problems do not cause issues. But what a great video, it shows how much Elon trusts you. I know we get some fantastic close up footage from other channels, which we are all so grateful for, but I get the feeling that Elon sometimes feels like it can get a bit too invasive. He mentioned in this video about 12k cameras with insane zooms showing every little detail. I think he likes that you do not go out of your way to get such footage, and by building that respect he his willing and happy to invite you in. This must all be so surreal for you Tim, go back in time about 3 years and you could never have guessed how things would turn out, your dedication and hard work is certainly now being rewarded.

The integral of the force vs time curve is the total impulse. This is actually very tricky to calculate, because force measurements can be very noisy. When integrating noisy data, it can overestimate the actual performance and can require filtering. This leads to the next conundrum as the integration can become very sensitive to the filtering frequency. So even that figure of merit, as simple as it’s stated, is very complicated.

Ullage gas refers to the gas or empty space within a rocket or spacecraft's propellant tank. In a rocket engine, propellant is stored in tanks, and as the propellant is consumed during thrust, the remaining empty space in the tank needs to be filled with a gas to maintain pressure and prevent the tank from collapsing. This gas is known as ullage gas. The purpose of ullage gas is to ensure that the propellant is delivered properly to the engine. It helps to maintain a consistent flow of propellant by exerting pressure on the remaining liquid fuel or oxidizer, preventing vaporization or cavitation that could disrupt the engine's performance. Ullage gas is typically inert, such as nitrogen or helium, and is often used in combination with a pressurization system to maintain the desired pressure in the propellant tank. Overall, ullage gas plays a crucial role in ensuring the proper functioning and stability of rocket engines by maintaining pressure and facilitating the flow of propellant.

Head, end, and throat cooling in thrusters is a cooling technique specifically used in rocket engines to prevent overheating and ensure optimal performance. Thrusters generate a significant amount of heat during operation, and cooling systems are crucial to maintain the integrity of the engine components and prevent damage. In the context of rocket engines, head, end, and throat refer to specific sections of the combustion chamber and nozzle: 1. Head cooling: The head region refers to the upper part of the combustion chamber. It is typically exposed to the highest temperatures and pressure. Cooling channels or regenerative cooling systems are often incorporated into the head section to circulate a coolant, such as liquid fuel or cryogenic propellants, to absorb heat and prevent the chamber wall from overheating. 2. End cooling: The end region refers to the lower part of the combustion chamber, near the nozzle exit. It is also exposed to high temperatures and pressure. Cooling techniques such as film cooling or regenerative cooling can be employed in this section to cool the chamber walls and protect them from the intense heat generated by the combustion process. 3. Throat cooling: The throat is the narrowest part of the combustion chamber, located between the head and end regions. It is subjected to extremely high temperatures and high-velocity gases. Cooling methods, such as film cooling or impingement cooling, may be employed in the throat area to remove excess heat and prevent damage to the chamber walls. The primary goal of head, end, and throat cooling in thrusters is to maintain the structural integrity of the engine components and prevent thermal degradation. By implementing effective cooling techniques in these critical areas, rocket engines can operate at high temperatures and pressures without compromising their performance or risking catastrophic failure. It's important to note that the specific cooling methods used in thrusters can vary depending on the design and type of rocket engine. Engineers carefully consider factors such as the propellant type, operating conditions, and material properties to design efficient cooling systems that can withstand the extreme conditions of space exploration or other propulsion applications.
