What is the Orion Project?

In the late 1950s, American scientists made a research plan for Mars exploration, namely "Orion Project". The unmanned spacecraft "Olian" designed for this purpose is believed to be driven by the shock wave generated in the interval between nuclear explosions. Later, scientists improved the design of Olian, making it a manned starship, flying to Sirius or other planets. The huge spacecraft can carry hundreds of male and female astronauts and their descendants, and everything that sustains their lives and work. The nuclear pulse propulsion device of the spacecraft uses a small hydrogen bomb to explode to generate electricity. The explosive power of a hydrogen bomb is equivalent to 1000 tons of explosives, and it explodes every 3 seconds or 10 seconds. /kloc-within 0/0 days, the spacecraft can accelerate to a speed of 10000 km. Due to the speed effect, it took 280 years to reach Sirius.

1973,65438+10 In October, the British Interstellar Navigation Association established a team of scientists headed by Allen Bond. In the "Daedalus" research project, they designed the "Daedalus" automatic spacecraft to fly to Barnard, which is 6 light years away from the Earth. The spacecraft consists of two stages and is propelled by nuclear pulse. The spacecraft has a total length of 200 meters and an initial mass of 54,000 tons, including 46,000 tons and 4,000 tons of two-stage nuclear fuel respectively.

Using hydrogen isotope neon and helium isotope helium -3 as fuel, they are mixed at a low temperature of -270℃ to make pellets with a diameter of 2 to 4 cm. When the power plant works, fuel particles are injected into the combustion chamber of the engine. At the same time, dozens of electron beam generators emit high-energy electron beams, bombarding the nuclear fuel pellets together, raising the temperature to tens of millions of degrees, and the nuclear fusion reaction of neon and helium -3 generates huge energy, pushing the spacecraft forward. If 250 pellets are burned per second, that is, the nuclear pulse rate reaches 250 times per second, the thrust can be approximately continuous.

After 2.05 years of work, the first stage was separated from the second stage. The second stage continued to work 1.76 years, making the speed of the spacecraft reach 36,000 kilometers per second. Because of the speed effect, it can fly to Barnard for about 50 years. A few years before approaching Barnard, a probe was released to detect Barnard, its planets and moons. It took about 60 years after the launch of the spacecraft to receive the detection information of the "Daedalus" spacecraft.
