If we’re going to go to Mars, we need an engine that can match the power of Starship. The world’s most powerful rocket in the name of science and getting invaluable data pushes the limits of the SpaceX Raptor engine.
Sometimes going even further and recently we saw a test that broke records on Twitter learning some fascinating references from Elon and let’s check them all out in this episode Hello everyone welcome to Elon Musk Evolution where we bring you the most recent news about Elon Musk and he.
First let’s look at what goes into making a rocket engine. You may need a basic understanding of the underlying concepts of an internal combustion engine on Earth to understand the difference between a rocket engine and your typical internal combustion engine in a car, an explosion. The energy that is released is the result of the combustion that takes place.
When a fuel is ignited after being mixed with oxygen in the combustion chamber of an automobile engine, the gasoline vapor and air are combined and a spark is used to start the mixture. The force of this mini-explosion forces a piston down. is pushed towards and the motion of the piston rotates a shaft which rotates the wheels.
However for today’s episode you just need to be aware of the fact that fuel and air and spark equals the energy of the explosion, even though the mechanics of a car engine are much more complex. In this case the oxygen content of the air is important because combustion unless sufficient is present, there is no oxygen as the rocket ascends through the high atmosphere and eventually the resulting liquid oxygen must also be carried into the vacuum of space.
The Starship launch vehicle, powered by rockets other than fuel, is currently being actively developed by SpaceX to build a dependable machine by 2019 that could one day travel into orbit and in the years beyond each spacecraft and rocket component. can be tested. And development is happening.
The integrated test flight, which took place on April 20 at the Starbase facility in Boca Chica Beach, Texas, gave engineers a chance to collect critical data on the Raptor engine and stainless steel rocket even as the vehicle entered orbit during a four-and-a-half second flight. That took it about 40 kilometers above Earth, high enough for engineers to determine what improvements needed to be made to get them into orbit.
The Super Heavy rocket was launched with a thrust of at least 30 out of 33 Raptor V2 engines. orbit methylox is a mixture of cryogenic liquid methane and liquid oxygen, the fuel used by the Raptor V2 engine, which SpaceX describes as more power less parts, was used to power this Starship prototype, while The mass of the Raptor V1 engine is 2,000 kg.
The Raptor V2 engine weighs 1600 kg and both sea level versions have the same nozzle exhaust diameter and similar dimensions, the current Raptor V2 produces around 230 tons of thrust, compared to around 185 tons for the Raptor V1, the company used fewer components Added this it was able to increase thruster performance while reducing the manufacturing process, which is important for being able to one day build a fleet of hundreds of Starships to establish bases on the Moon and Mars.
The third iteration of the Raptor engine set a new thrust record this week The Raptor V3 has now reached a chamber pressure of 350 bar or 269 tons of force. Congratulations to the SpaceX propulsion crew have been announced 33 times, SpaceX creator Elon Musk said on Twitter on May 13. Raptors in the Starship Super Heavy Booster, so a total thrust of 8,877 tons or 19.5 million.
Pound The Starship is set to become the most powerful rocket in history Question was submitted on Twitter by a Tasmanian journalist I wonder if the Raptor V3 looks different or is more similar to the V2 User Comment Musk said are we secondary enough Can remove the structure and integrate a little fiddly bits so we can locally protect the rest and remove the engine heat shield compared to earlier iterations.
The bulk of the engine can be reduced making it more compact and faster for mass production, let’s use the Saturn V rocket which produced 7.6 million pounds to illustrate the increased power of the Raptor v3 , thrust as a comparison and was used to launch NASA’s Apollo Men to the surface of the Moon, the Space Launch System is a replacement rocket for the Saturn V that was designed by NASA and has a maximum thrust of 8.8 million pounds Is.
Not in use as the Saturn V is no longer in use, but to be launched in November 2022, the working rocket according to NASA has used more power than any rocket at liftoff with a capacity of 19.5 million, SpaceX Ka’s Starship is to become a super heavy pound, SLS is predicted to fall apart.
SpaceX engineers prepare the advanced spacecraft as it approaches orbit for an upcoming orbital flight test effort this year, with the Raptor V3 engine being tested at the McGregor Texas plant as posted by NASA Spaceflight.
The Raptor chamber wall may have the highest heat flow of anything ever done, Musk said in response to the footage, adding that this is uncharted territory and that a Raptor engine is SpaceX’s daily average production rate. The company manufactures and inspects the engines, counting through November 2022 and approximately 200 Raptor engines at the McGregor facility.
According to company officials, SpaceX currently has more engines than it can fly with the 260 tons of thrust each Raptor V3 is capable of producing with SpaceX hoping to keep up. The cost of each Raptor at around $1,000 USD comes out to a little over $250,000.
Starship development is expected to cost around $2 billion according to Elon Musk’s previous statements this year and now that we know the details of Raptor Engine 3, let’s see how Raptor 1 and 2 compare and how SpaceX has developed the Raptor How the Raptor engine evolved from the introduction of Raptor Engine 1.0, which was used on the Starhopper SN5, SN6, SN8, SN9, SN10 and SN11, and Raptor V 1.5, which was used on the SN15, 20 and B4 Was.
What changes SpaceX has made to the new Raptor, known as Raptor 2, in recent months and why these changes are beneficial to Starship The new Raptor includes performance and reliability improvements to both super-cooled liquid oxygen and super-chilled liquid methane Are.
The Raptor engine features a full flow staged combustion cycle engine that will power SpaceX’s Starship next-generation spaceship Raptor engine, the third ffscc engine ever built and the first to leave the test stand. The cycle is highly optimized to maximize ffscc impulse.
33 Raptor engines produced by a given amount of fuel will be packed inside the Starship’s super heavy first stage 20 non-Gimbling engines in the outermost ring 10 Gimbling engines in the middle ring and three Gimbling central engines in the innermost ring Future Raptor Improvements This is the number Drop by SpaceX is anticipated. Three vacuum optimized non-gimbaling engines and three sea level gimbal engines make up the six total engines found on the second stage, dubbed Starship.
While Elon Musk has commented that additional vacuum optimized engines are likely to be added once the ship’s length is increased to three, there is no information to suggest that the engines used to build the Raptor are between Raptors 1 and 2. Content has changed a lot. SpaceX is working to eliminate 3D printing as much as possible because of its inefficiency but high cost and poor manufacturing rate.
As they say, one of its most amazing features is the Raptor’s ability to gimbal 15 degrees on the Y and Z axis required for Starship’s flip and burn landings, the rs-25 gimbals 12.5 degrees while the SpaceX Merlin engine first stage 5 degrees, making the Raptor 1’s 15-degree range noticeably wider than when the first Raptor 2 was finished.
The engine was seen in early 2022. Once Raptor 2 manufacturing began, SpaceX stopped making all Raptor 1.5 engines because a lot of the plumbing and sensors had been removed. The Raptor 2 engine no longer has the Christmas tree appearance that the first Raptor had and instead has a much cleaner appearance with lots of development sensors throughout the Raptor to monitor pressure and temperature while SpaceX was learning plumbing on the original Raptor.
Plumbing became even more straightforward as a result of combining several valves into valves. The plates are an important step toward SpaceX’s aim of eliminating all engine covers from the booster, which will reduce the booster’s bulk by about 6 tons from the engine, a significant portion of these components to make it more flame and heat proof.
Not the best part in this situation by Elon Musk. Compared to earlier iterations of the Raptor the oxygen and hot CH4 gas are ignited without the need for an additional torch igniter.
Swapping them adds mass to the entire engine and reduces pressure. SpaceX is now able to remove many flanges from the engine as the design is more reliable and it also expects to remove all flanges from the Raptor 2.5 which can lift up to 250 tons. Will increase. And the most significant modification was the opening of the throat to allow more propellant to pass through the engines starting on Rocket 12.
The expansion ratio, which is the ratio between the area of the nozzle exit and the area of the throat, decreases. This change requires the nozzle to exert more effort to convert the higher pressure into higher velocity. High expansion ratio and the engine is exclusive to the Raptor 1 and Raptor 2. The more impulse compared to the nozzle exit diameter on the Raptor 1 and Raptor 2 the better.
The remainder of the engine is basically the same size, despite the Raptor 2 weighing 1600 kg compared to the Raptor 1’s 2000 kg. This makes it much lighter than the MCC pressure of the Raptor 2 rocket engine which is at an incredible 300 bar highest MCC pressure. 1. Raptor 50 times above Russian RD-180 which operates at 267 bar pressure.
The Raptor, which held the previous record for highest MCC pressure, achieved a large amount of thrust as a result of the wide throat and high chamber pressure Raptor 1.185 tons of thrust. While the Raptor 2 produced 230 tons of thrust, the reduction in ISP widening the throat is a one percent drop. The Raptor 1 had an ISP of about 330 seconds while the Raptor 2 had an ISP of 327 seconds.
The increase in thrust leads to an acceleration of 9.8 m/s, when the thrust ratio is 1.25 to 1.80 percent, despite the drop in exhaust velocity due to the reduction in gravity well before the fight against Earth’s gravity. Thrust is lost fighting gravity and only 20 percent of the thrust is used to propel the vehicle at 0.25 G. This infinitely increases the net effort exerted on the vehicle, despite only a 25 percent increase in thrust.
This results in a 100 percent increase in the effort exerted on the vehicle. Even though growth is in full swing, just 16 percent at liftoff. The TWR of the Raptor 1 will be around 1.25 while the TWR of the Raptor 2 will be 1.5. A one percent drop in ISP isn’t nearly as dramatic. Because a 100% increase in performance at the start of a full flight gives several advantages, including a reduction in the distance the booster has to travel, becoming stationary at the end of its burn.
Thereby reducing the fuel requirement for the back burn of the booster. And now let’s look at another SpaceX rocket engine, the Merlin engine. The Merlin engine is an open cycle gas generator engine, meaning that the propellant is burned in a gas generator and the resulting hot air is used to drive the engine’s pumps, then the gas is ejected, thus the engine Also known as a.
open cycle since some is thrown away as mentioned earlier the oxygen must be carried by the rocket as it is required for combustion Ultra Refined Kerosene or RP1 fuel and liquid oxygen are fed through a turbo pump system to the Merlin engine is fed into the combustion chamber. The second stage of the rocket is fed through separate tanks. The pre-burner turbine shaft and two pumps make up the turbo pump assembly. The pre-burner resembles a small rocket engine in many ways.
The pre-burner’s exhaust drives the rotation of a turbine shaft which rotates two pumps that pump fuel and oxidizer into the combustion chamber and are connected to the turbine, two smaller fuel and oxygen pipes that are connected to the pumps, supply the pre-burner which runs on the same fuel and oxidizer as the main engine.
and the pumps control the flow of fuel and the oxidizer ouch in the pre-burner triethyl aluminum triethyl borane what a chemical compound that spontaneously ignites when exposed to any form of oxygen, a limited amount of ignition is used by the Falcon 9 was used to solve the problem. A separate piping system is used to supply this compound and a small amount of fluid to the Merlin engine.
The oxygen content in the pre-burner automatically ignites the spinning turbine. A continuous supply of fuel and liquid oxygen is supplied to the combustion chamber as a result of which the pumps start to operate and ignite the cycle in a uniform manner. Once the fuel and oxygen enter the combustion chamber the continuous flow of fuel and oxygen allows for continuous combustion and the combustion of the Merlin engine generates 190000 pound-feet of thrust, using a separate small nozzle for discharge is done.
This took a long time to accomplish due to the complexity of the process due to the complex mechanisms on the Saturn V moon rocket, with the engine taking a little over six seconds to reach its maximum power, ending the first stage as soon as the burn was over.
The M-back engine ignition of the second stage uses the center of one of its nine Merlin engines to propel the rocket’s payload into its intended orbit, a new video shows SpaceX currently is developing technology that can strengthen the ground beneath orbit.
The launch pad of its massive Starship rocket. The first test launch of a fully stacked Starship vehicle caused considerable damage to the launch pad, with the sheer power of Starship’s 33 first-stage Raptor engines on that particular day sending broken pieces of concrete into the launch pad. While doing this, made a hole in the bottom of the pad. In the dusty air, Elon Musk tweeted the next day that SpaceX was already working on solutions to avoid or minimize such damage.
A day after the eagerly awaited test flight, the billionaire entrepreneur touts a giant water-cooled steel plate to go under the launch mount. that such activities had begun three months earlier, with SpaceX launching Starship on April 20 despite the plate system being behind schedule because they believed Starship’s concrete would last a takeoff as we did on 20 Did it in April.
The steel plate work has progressed really fast since then with the business recently pitting a prototype plate against the power of a single Raptor on Friday 19 May. Meanwhile another test of SpaceX’s massive Starship spacecraft is scheduled to begin Thursday morning, May 18 at the Starbase facility in South Texas.
On Thursday, representatives of a suborbital pad company announced via Twitter that SpaceX will test six Raptor engines on Ship 25 in a static fire test. Elon Musk has said that the objectives of the upcoming Full Stack Starship test flight will be similar to those that SpaceX is preparing.
