Nuclear fusion (hot plasma) propulsion technology!‘Pulsar Fusion', a UK-based aerospace start-up company founded in 2011, is now developing a next-generation nuclear fusion propulsion technology rocket. This new research may pave the way for astronauts to travel infinite distances in the near future.In June 2023, the UK-based company 'Pulsar Fusion', which specializes in clean space propulsion systems and services, announced a collaboration with Princeton Satellite Systems, an American firm. This partnership aims to utilize artificial intelligence (AI) in the creation of a hyper-fast space propulsion system capable of reaching Mars in just 30 days.They announced that its new nuclear fusion propulsion system is designed to exceed speeds of 500,000 miles, or 8,04672 km per hour, with astronauts onboard—far beyond current spacecraft capabilities. Researchers are optimistic that this technology will revolutionize space travel and hope to build a prototype propulsion system by 2027.According to their report, the Princeton field-reverse configuration (PFRC-2) reactor may create hot plasma produced by its system that will surpass the temperature of the sun. They have constructed an 8-meter chamber for nuclear fusion, where temperatures could reach several hundred million degrees.The researchers are optimistic that this heat could facilitate speeds exceeding 500,000 miles per hour in infinite space, and an electromagnetic field will be employed to control the extrime hot plasma.The Pulsar Fusion Company is currently in the experimental stage of developing its nuclear-powered rocket engine-based spacecraft. They plan to achieve readiness within 2027, following extensive research and development.However, it is premature to determine its distinctiveness or potential for success, and information regarding its travel capabilities to Earth remains undisclosed. This next-generation technology has the potential to transform space exploration in the near future, if it comes to light.Source: World Nuclear News, Pulsar Fusion, BBC, Interesting#aviation #aviationlovers #aviationdaily #aviationgeek #aviationupdates #nuclearfusion #SasidharanMurugan #Itzmemsd

    IS SPACE TRAVEL REALLY POSSIBLE?These are some ways it can be in the future·POWERED BY NUCLEAR FISSION:First method can be a spaceship fueled by fission reactors, nuclear-electric or plasma engines which can run at low thrust for extended periods of time and potentially achieve far higher speeds than chemically fueled cars or nuclear-thermal rockets. Within the next century, such spacecraft can be used in fission-fragment rockets to produce high-speed jets of fission fragments that can shoot out at up to 12,000 km/s. There is a chance for extremely high specific impulse and high specific power with this propulsion system. in 1968, Freeman Dyson, a member of the Project Orion team, proposed an interstellar spacecraft weighing 100,000 tons that could reach a delta-v of 20,000 km/s, meaning it may take 130 years to reach Alpha Centauri.·POWERED BY NUCLEAR FUSION:Based only on energy considerations, fusion rocket starships propelled by nuclear fusion processes should theoretically be able to reach speeds on the order of 10% of the speed of light. These would "burn" fuels made of light elements, such as tritium, deuterium, 11B, and 7Li. projects like Deadalus performed by British interplanetary society and project longshot sponsored by US naval academy and NASA completed in 1988 which showed that a spacecraft can achieve characteristic velocities of >300km/sec with a acceleration of 0.0017 g.·ROCKETS WITH EXTERNAL ENERGY SOURCE:Externally powered rockets, like lasers, have the potential to replace their internal energy source with an energy collector. An ion thruster powered by energy broadcast to it from a base station laser is how Geoffrey A. Landis proposed to power an interstellar probe. Lenard and Andrews suggested accelerating nuclear fuel pellets toward a Mini-Mag Orion spacecraft using a base station laser before lighting them for propulsion.·HELICAL ENGINE:The helical engine concept, put out by NASA scientist Dr. David Burns in 2019, would accelerate particles to almost the speed of light with the use of a particle accelerator. It is thought that this mass change could produce acceleration because particles moving at such speeds pick up mass. Burns claimed that the spaceship might hypothetically travel at 99% the speed of light.·WORMHOLES:Theoretical spacetime distortions known as wormholes are hypothesized to be able to connect any two points in the universe via an Einstein–Rosen bridge. The possibility of wormholes in real life is unknown. Despite the fact that there are solutions to Einstein's general relativity equation that permit wormholes, every known solution makes an assumption of some kind, such as the existence of negative mass, which may not be tenable. Cramer and colleagues, however, contend that these wormholes could have been formed in the early cosmos and stabilized by cosmic strings. In the book Lorentzian Wormholes, Visser discusses the general theory of wormholes.

    Nuclear energy has been investigated for space propulsion for many years. It is the technology of choice for future missions to Mars and beyond. Last June, ESA awarded to CEA two feasibility studies to investigate alternative space propulsion systems. The names of the two studies are Alumni and RocketRoll.These are 2 different ways of using nuclear fission energy for propulsion: either with LH2 (Alumni project) or in combination with an ion thruster using Xenon (RocketRoll project).These principles are not new. They have already been developed in the past with projects such as NERVA, SP-100, RD-0410 (USSR), ERATO, MAPS, etc…Even if NASA and DARPA decided also to study the first option (nuclear thermal) in the DRACO project, the 2 main challenges are: -the use of LH2, -and the high temperature of the radioactive core. The current on-orbit storage record for cryogenic LH2 is about 12 hrs (Centaur upper stage).The RocketRoll concept also faces some technological hurdles for cooling the reactor core. The only method to dump heat overboard in space is through radiative cooling. This makes the cooling system very heavy with massive radiator fins. We are talking here of a radiative surface close to 100m2. And at the end, the thrust is much lower than nuclear thermal propulsion.But even with all these difficulties and challenges, the number of projects around the world show that it is worth developing these concepts. Motivation is high…

    In our previous 4 blogs, we have gone over nuclear-powered propulsion via fission- the splitting of nuclei. There is, however, another form of nuclear propulsion: fusion - the fusing of nuclei. Fusion is in its nascent stage, yet that hasn't stopped propulsion development. We will go over how fusion propulsion works and the history of fusion propulsion, concluding with the work being done today.All fusion propulsion takes the heat generated from fusion and converts it, through various means, into kinetic energy. Differences emerge when we consider developments on how fusion should be achieved and how that energy should best be converted into kinetic energy.Much like its thermal counterpart, work started early. It is important to remember that while fusion wasn't available for power generation, humanity has already mastered it to make bombs. This became the backbone of Project Orion, a DARPA and NASA initiative in the 60's to achieve interplanetary flight by exploding fusion bombs behind a rocket for thrust. This idea metamorphized into Project Daedalus: a 54-megaton fusion-powered rocket tasked to reach Barnards Star at 12% the speed of light through the fusion of helium pellets. In the 80's expectations were scaled down with the VISTA which sought to bring 100 tons of payload to Mars and 130 days, with 41 tons of fusion fuel. The Discovery 2 paved the way for current work on fusion propulsion, it aimed to use magnetic confinement and was acclaimed to send 172 metric tons of payload to Jupiter in just 118 days.While expectations continued to be scaled down, with plans for Mars seeming out of this world (pun intended), progress was being made.Pulsar Fusion, in collaboration with Princeton Satellite Systems, now takes the lead for fusion propulsion - with ample competition- through their new "Direct Fusion Drive"(DFD) . RF transmitters and magnets heat up and confine a region of fuel-rich plasma where the fuel - helium and hydrogen - undergo fusion, releasing heat. This heat is transferred to another source of plasma that is ejected out of a magnetic nozzle, generating thrust. The DFD is expected to have a specific impulse of 2.3*10^4 alongside a decent thrust of 12.5N. While some of us may feel reminiscent of EP, the DFD can still make good time with interplanetary missions. 4 DFDs can get 105 tons to Mars in about 160 days with 0.76 tons of fuel (Using some overly simplified math). Its the ability of fusion to have extremely high specific impulses while having a thrust that can be measured in newtons - while still having energy left over for electrical power - that allows it to be considered for niche missions like detecting exoplanets and even deflecting asteroids. It is expected to be ready by 2027, alongside Project DRACO.Fusion power still has a long way to go on Earth, but if we crack the code, we would not only leapfrog development on Earth, but open new opportunities within this solar system and perhaps beyond.

    Which Nuclear fission or fusion for space? seems that a fuel issue will hit soon. This will need to take fuel away from power plants and it seems it is showing signs of not a lot left as they use more.Would be better to adopt fusion as hydrogen and water are available more readily as well as for rocket fuel. One safer system for power and rockets on Mars and the moon.

    Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a modeling tool for assessing the potential use of a nuclear device to defend the planet against catastrophic asteroid impacts.The research, published today in the Planetary Science Journal, introduces a novel approach to simulating the energy deposition from a nuclear device on an asteroid's surface. This new tool improves our understanding of the nuclear deflection's radiation interactions on the asteroid's surface while opening the door to new research on the shockwave dynamics affecting the inner asteroid.This model will allow researchers to build upon the insights gained from NASA's recent Double Asteroid Redirection Test (DART) mission, where, in Sept. 2022, a kinetic impactor was deliberately crashed into an asteroid to alter its trajectory. However, with limitations in the mass that can be lifted to space, scientists continue to explore nuclear deflection as a viable alternative to kinetic impact missions.Nuclear devices have the highest ratio of energy density per unit of mass of any human technology, making them an invaluable tool in mitigating asteroid threats, said LLNL physicist Mary Burkey, who led the research."If we have enough warning time, we could potentially launch a nuclear device, sending it millions of miles away to an asteroid that is headed toward Earth," Burkey said. "We would then detonate the device and either deflect the asteroid, keeping it intact but providing a controlled push away from Earth, or we could disrupt the asteroid, breaking it up into small, fast-moving fragments that would also miss the planet."#asteroid #impact #mitigation #nuclear #physicshttps://lnkd.in/g86C5xAd
