Last time, when Wan Ling woke up three years later, he was greeted by thousands of cutting-edge sci-fi uniformed soldiers, welcoming the return of heroes, and each soldier shouted: Hero! And in the past three years, He Ling has used his expertise to help the entire resistance force.

First of all, some modifications were made on the regular guns. First of all, the soldiers use some laser weapons, such as some laser guns, etc. The killing mechanism of the laser gun: The beam irradiates the high temperature to kill, so if the opposite side is a reflective enemy or an enemy resistant to high temperatures, the effect of the laser gun will be reduced, and it will not be completely ineffective, but on the battlefield, time is life, and once the killing effect is reduced, then it is very dangerous. Therefore, conventional kinetic weapons, such as normal guns, first of all, normal guns kill aliens, and generally the "nuclear" effect comes. The first invention of the "nuclear gun bullet" simply means that ordinary bullets are fired with ordinary ones. The range of the medicine is about a few hundred meters, if it is emitted by "all-anion ionized salt". The medicine has a range of several kilometers, and the "nuclear gun shell" is simply fired. The medicinal nuclear materials "deuterium" and "tritium" are then used to carry out nuclear fusion with a laser to launch the bullet. "Bullet" opened up a lot of subsequent technologies. "Nuclear launch. Medicine" and "all anion ions" emitted more than "full anion salt". Hundreds of times larger than a gun, which can almost intercept satellites, is one of the same principles, but the warhead is small, "laser fire hydrogen. "The bullet hit the effect of a missile.

Bullets can be changed like this, so can shells also be changed in this way? It is also possible to launch on a similar principle. The medicinal nuclear materials "deuterium" and "tritium" are then used to carry out nuclear fusion with lasers to launch artillery shells, but the shells are larger and more powerful. Medium-caliber anti-aircraft guns have a firing altitude of more than 10,000 meters, and after such a transformation, it is simply easy to use to directly intercept alien fleets in low-earth orbit, and it can also carry "laser fire hydrogen. The warhead is simply extremely powerful, and there is almost no alien fleet in near-earth orbit.

In space, He Ling developed the "Nuclear Rocket Thruster", the engine of the nuclear rocket uses the energy released by nuclear reaction or the decay of radioactive materials to heat the working medium, and the working medium is discharged at high speed through the nozzle to generate thrust and make the spacecraft fly at high speed. At present, the chemical rocket engine with the highest specific impulse is the liquid hydrogen and liquid oxygen rocket engine, which has a maximum specific impulse of about 450s, and the highest mass that the three-stage rocket can achieve under the existing technical conditions is about 10, and has basically reached the limit, so the maximum speed increment of the chemical rocket is about 10km/s. The specific impulse of the nuclear thermal rocket using hydrogen as the working medium can reach more than 1000s, and its velocity increment is greater than 22km/s, exceeding the third cosmic velocity (16.7km/s) It can be widely used in future space missions, including space missions in the solar system and interstellar space missions. The idea of a nuclear rocket was first conceived by the United States. Ulam, a nuclear scientist in China, proposed that nuclear fusion be used to make small hydrogen. The bullets explode one after another at the tail of the spacecraft, creating thrust. If the explosive yield of each atomic bomb is 1,000 tons of T.N.T, it is estimated that the spacecraft can reach a speed of 12 km/s after the explosion of 50 atomic bombs. At the end of the 50s of the 20th century, the United States. Taylor, a nuclear scientist, proposed a similar "Orion" plan, with an explosive yield of 2,000 tons of T.N.T (outside the atmosphere) for each atomic bomb, and a maximum speed of 70 km/s after 50 explosions.

Originally, the human fleet was a "laser-propulsion-all-anion ion salt technology booster rocket", but now it is equipped with a "nuclear fission fragmentation rocket", and the nuclear fission fragment rocket is a high-speed escape from the nuclear reactor during the nuclear fission process, thereby generating thrust. When an atom fissions, the rate of "split fragmentation" produced reaches 3% of the speed of light, or about 9 thousand kilometers per second. Beauty. National Lawrence S. George W. Brownmore of Livermore National Laboratory Halplin et al. designed a conceptual "split-debris" reactor that could control these high-velocity particles. The reactor resembles a reactor around a. A stack of "records" rotating in cylindrical towers, each of which is composed mainly of graphite, which is covered with radioactive fuels such as plutonium or americium. When these fuels are rotated into the cylindrical column, they produce a controlled chain fission reaction with the radioactive material in the column. A powerful magnetic field applied to the reactor binds the "split debris" together and ejects them in one direction, increasing the rocket's velocity to about 18,000 kilometers per second, or 6% of the speed of light. The speed of these three thrusters has greatly increased, which has greatly increased the combat effectiveness of the human fleet, and He Ling has developed the "Space Nuclear Fish. Ray "encounters the alien fleet in addition to normal firepower with" space nucleus. Thunder" after the battle power soared.

In terms of aircraft fighters and bombers, He Ling developed a "nuclear ramjet engine", which uses the thermal energy of nuclear fission to heat the working fluid to a very high temperature, and then accelerates the engine to the supersonic flow by shrinking and expanding the nozzle to produce thrust, designing suitable intake and exhaust channels, and using the ambient atmosphere as the working fluid to replace the propellant supplied from the storage tank through the pipeline, then the nuclear thermal rocket becomes a nuclear ramjet engine. The effect of equipping this engine with aircraft fighters and bombers is very good, civil aircraft have undergone this transformation, the load has increased by dozens of times, the fighter aircraft is equipped with this engine, the speed has increased greatly, and the bomb load has also increased greatly, and the bomber is equipped with this engine, and the bomb load has increased dozens of times, and it has bombed aliens and ground forces in various ways. Moreover, with this technology, the "nuclear air-to-air missile" was invented, which was used for air-to-air, simply put, the "nuclear rocket thruster" was used to press the speed on the "nuclear air-to-air missile", and the range increased, of course, there was a new way to hit the silver-gray round UFO, and in short, the "nuclear air-to-air missile" was equipped with "laser fire hydrogen. The warhead of the bomb has a shroud to limit the nuclear radiation and shock wave in one direction without scattering radiation, and this "nuclear air-to-air missile" hits the silver-gray round UFO and detonates the "laser fire hydrogen. Under the restriction of the shroud, the nuclear radiation and shock wave will only rush forward, so the silver-gray round UFO will be destroyed by the nuclear radiation and the shock wave, so that the silver-gray round UFO can finally be destroyed by "conventional" fire.

If the silver-gray round UFO can be destroyed, then the "fortress" can also be breached, in addition, He Ling has developed controllable nuclear fusion, so far, energy is almost no problem, in the first timeline, every city and conditional counties and townships in Huaxia country deploys a laser, particle beams and other high-energy weapons, and now dozens of lasers, particle beams are no problem, there is no alien fleet in the earth orbit facing Huaxia country, and the alien fleet is hiding on the back, so the battle situation continues to gain advantages.
