SpaceX, International Space Station, NASA, Falcon 9, Liquid oxygen What if Starship 20 & Super Heavy Booster 4 Explosion?
The stacked starship, 20 and super heavy booster 4 is the worlds tallest rocket and starship is designed to do complex, flips and maneuvers upon landing. While we all hope that the flight will go well, it is not possible to guarantee with 100 certainty that errors or irregularities will not occur. So it is time now for us to consider the question what the hell will happen if spacexs starship 20 and booster 4 explode, especially what would they be an equivalent to tnt, but first lets look back at the previous terrifying explosions in the history of rockets. In the world, including those of the previous generation of spacex rockets, the fully reusable launch system for eventual moon and mars trips is no stranger to explosions, ruptures and failed landings. Simply because starship is a new system trying to do unusual things. There are plenty of ships that explode already without there being a great risk to the launch site. All that happened there were minor repairs being needed after fairly minimal damage and a little debris rain. We had starship sn1 tank ruptures in the pressure test, starship sn4, explodes after engine test, starship sn8 crashes in a fireball landing. All of them had a maximum methane load of roughly 10 tons in common, but a fully filled. Starship stack will hold a propellant capacity of 1 200 metric tons of liquid methane and liquid oxygen nearly 100 times as much so avoiding a rapid unscheduled disassembly should be the highest priority.
Otherwise things will deteriorate. Falcon 9. now talk about another big explosion of falcon 9. In 2016., the explosion occurred during the preparation for the static fire test of the rockets engines and no one was injured. According to spacex, the blast reportedly shook buildings several miles away. The company confirmed the loss of the falcon 9 an hour later, assuming it was fully filled. The falcon 9 contains around 160 tons of rp 1 as its fuel. Only 16 of the fuel mass in the full starship stack and combusted, not all at once, but during two explosions and burning afterward falcon heavy falcon heavy has 27 engines with three main boosters that can ostensibly land themselves after delivering payloads to space. Spacex is bringing some serious firepower to blast a rocket of that size into space. Elon musk spacexs ceo told reporters on tuesday there will be the equivalent of four million pounds of tnt on the launch pad, which will generate 5 million pounds of thrust at liftoff thats. As much explosive power as a tactical grade nuclear weapon, around 1.8 kilotons according to an animation released by spacex, approximately 90 minutes before launch spacexs launch director, will give the go ahead to load up the rocket with fuel. The rockets fuel. A mix of rocket grade kerosene, known as rp 1 and liquid oxygen is highly flammable. In other words, if the launch is unsuccessful, the rocket could explode with the force of a nuclear weapon. Obviously, if starship blows up, it would result in much larger and longer duration.
Conflagrations than those talking about tnt tnt equivalent is a convention for expressing energy typically used to describe the energy released in an explosion. The ton of tnt is a unit of energy defined by that convention to be 4.184 gigajoules, which is the approximate energy released in the detonation of a metric ton, 1000 kilograms of tnt, in other words, for each gram of tnt, exploded, 4.184, kilojoules or 4184 joules of Energy is released and one next one of the biggest rocket explosions ever was. The n1 in 1969 launch took place at 11, 18 pm moscow time for a few moments the rocket lifted into the night sky. As soon as it cleared the tower, there was a flash of light and debris could be seen falling from the bottom of the first stage. All the engines instantly shut down except engine number 18.. This caused the n1 to lean over at a 45 degree angle and drop back onto launch pad 110 east. The nearly 2 300 tons of propellant on board triggered a massive blast and shock wave that shattered windows across the launch, complex and sent debris flying as far as 10 kilometers six miles from the center of the explosion. The entire rocket contained about 680 000 kilograms or 680 tons of kerosene and 1780 000 kilograms or 1780 tons of liquid oxygen using a standard energy release of 43 megajoules per kilogram of kerosene gives about 29 terajoules for the energy of the explosion.
Investigators later determined that up to 85 percent of the fuel in the rocket did not detonate, meaning that the blast yield was likely no more than one kiloton tat equivalent comparing explosions of initially unmixed fuels is difficult, being part detonation and part deflagration. So now we come to the main part of this video. What will happen if there is an explosion with a fully stacked starship for starship, fully stacked? A famous reddit user calculates it by looking up the energy released by burning one kilogram of the fuel mixture. According to a tweet from elon, the total amount of fuel should equal 4, 800 tons with 78 being oxygen and 22 being methane. The amount of energy released from methane could be found here. He chose the gross value recommended by this. The energy released from one kilogram of methane should therefore be equal to 55 384 kilojoules. Using this, we can calculate the total energy to be equal to around 55.384 megajoules per kilogram times, four million eight hundred thousand kilograms times 0.22, which equals hundred 58 million thousand five hundred and four mega joules, which equals fifty eight thousand. Four hundred. Eighty five point: five: zero, four giga joules one tnt seems to be equal to four point: one: eight four giga gigajoules, meaning we can calculate the tnt equivalent to b two million six hundred and fifty eight thousand four hundred and thirty two gigajoules slash four point: one: Eight four gigajoules equals thirteen thousand nine hundred and 978.
3709 tons of tnt equals 13.978 kilotons of tnt. It is a huge number while fully fueled, saturn v exploding on the pad would have released the energy equivalent of two kilotons of tnt to improve safety. The saturn emergency detection system, eds inhibited engine shutdown for the first 30 seconds of flight, the hiroshima bomb had a tnt equivalent to around 15 kilotons of tnt talking about residual fire in estimation of fireball from saturn vehicles. Following failure on launch pad, it was noted the high probability that, in the event of a saturn low altitude failure, large quantities of uncombusted rp1 fuel would rain onto the launch pad creating residual pools that would burn until long after the fireball had disappeared. These fires would prevent ground crews, including rescue personnel from accessing the area, potentially with disastrous consequences. Starship, on the other hand, does not have any ambient temperature liquid fuels. This can have both positive and negative spins. On one hand, all fuel would quickly evaporate in the event of a failure eliminating the possibility of residual fires. However, this evaporation also increases the likelihood that the expanding fuel cloud could ignite increasing the size and intensity of the fireball. It would likely be the most powerful, artificial non nuclear explosion in the history of the human race. If starship is to be crude, it is unlikely that any launch escape system would be able to safely protect passengers from the destructive force of the explosion. As such, the probability of a launch failure must be brought down.
This undertaking lowering probability of fault, possesses immense engineering challenges and will likely be one of the most difficult aspects of humankinds road to the red planet. Those are just some things we came up with. What do you think did we get something wrong regarding the damage potential? Where do you see risk that might trigger a large explosion during the first minute im sure the spacex team has considered all these factors and many more im really looking forward to seeing the flight of ship 20 and booster 4 right now, and that concludes todays episode. As always thumbs up, if you liked todays episode subscribe, if you havent and hit the bell, so you wont miss out on new spacex fans content. Thank you.
