Elon Musk’s plan to colonize Mars is ambitious, to say the least. To achieve their goals, SpaceX had to reimagine current technologies, while at the same time invent new ones. This is where the Raptor engine comes in, this methane-powered powerhouses could single-handily power Elon Musks' plans to reach Mars by 2024. Not to be confused with the Merlin engines that SpaceX uses on the Falcon9 reusable rockets for its current launches. The Raptor Engines are being developed specifically for SpaceX's Starship and its booster stage Super Heavy. This is a sneak peek into the ‘Insane Engineering behind SpaceX Raptor Engines’
The history of space-bound rocketry
The history of rockets can be traced back to the medieval ages, but we will be focusing on Rockets developed to take people and objects into space. Let us travel to 1898, a Russian schoolteacher Konstantin Tsiolkovsky first proposes this insane idea of using liquid propellants in rockets to explore space. Tsiolkovsky was convinced that the speed and range of a rocket were limited only by the exhaust velocity of escaping gases. For his vision and in-depth research, Tsiolkovsky is known as the father of modern astronautics. He was the first one to dream of leaving earth’s gravity well by strapping himself to a tube of burning gasses.
Fast-forwarding a few decades and rockets were being developed all over the world, not to be used as space-bound vehicles but as weapons. American engineers like Robert H. Goddard and German Engineers like Hermann Oberth would further lay down the fundamentals of developing rocket engines.
After the great wars ended, rocket technology had started maturing into a separate field of study. And with the Cold war fueling the space race. A new era of technological development was upon the field of Rocketry. These rockets were being designed to reach escape velocities and break free of the earth’s gravity. But traveling up earth gravity well was proving to be a difficult task.
And then on October 4th, 1957, the Sputnik rocket usefully broke from earth gravity to deliver the first-ever artificial satellite called the Sputnik 1. Sputnik was a heavily modified version of Soviet Unions R-7 Semyorka ICBM. Sputnik finally proved it was possible to travel up earth’s gravity well.
The rest is history as the USA followed suit with the development of its Saturn V rocket, which would take the first people to the moon. As time went on other countries started like China, the EU Space Agency and India, etc. started joining in with their indigenous rocket designs. All specially designed for one purpose and one purpose only, to break away from earth's gravity.
Raptor Fully flowing Cycles
SpaceX has set its eyes on Mars and to reach there they are rethinking rockets from the ground up. Reaching Mars and coming back would require a new spacecraft, powered by a totally new rocket engine unlike anything done before. SpaceX began the development of Starship (previously called the Big Falcon Rocket), a stainless-steel alloy-based spaceship supported by a booster stage called the Superheavy. Now all they needed was an engine to power all these rockets.
The first thing that SpaceX decided was to make the rocket reusable. Reusable rockets have always been SpaceX’s thing. They saw the massive costs of one-time use rockets that NASA was using for its space-bound missions and thought why we are just dumping millions of dollars of equipment in oceans when we can develop the technology to reuse it.
It took SpaceX a few years and a lot of sweat and blood to make reusable rockets a feasible option. And now Falcon 9s are the industry standard for reusable rockets. With the success of Falcon 9 and its merlin engines, SpaceX decided to stick to a similar philosophy of reusing.
When SpaceX said they would reimagine rocket engine technology, they really meant it. Raptor was developed on the Full-flow staged combustion cycle. This unconventional gas cycle has only previously been used in experimental rocket technologies and Raptor would be the first engine using this cycle to go to space. To put it into simpler terms, this cycle uses both oxidizer-rich and fuel-rich pre-burners. Usually, it is the one or the other, the cycle allows a full flow of both propellants through the turbines, hence the name. What this means is that the Raptor engine can be more efficient than other rocket engines because it has more control over the flow of the oxidizer and fuel.
