Description
Technical Field
The invention relates to the technology of space, rocket engine, chemical fuel, electromagnetic cannon, orbit, telescope, spotlight, manipulator, etc.
Background
At present, the spacecraft with the fastest human launching speed is a new horizon number detector, the launching speed is 16.3km/s, a rocket weighing about 600 tons is used, and the detector only weighs about 400 kilograms. Even if the detector speed is so high, it takes about 10 years to reach for flying to pluto. At present, even detectors in a solar system are always limited by too much consumption of chemical fuel, and great efforts are made to save fuel. In order to save 10% of rocket fuel, the time for the detector to fly to the target planet is increased by multiple times by adopting a complex orbit and accelerating by virtue of the gravity of the planet, and the time is 10 years for the detector to fly to the earth star.
From the zioerkvski rocket equation, the mass of fuel consumed when the rocket is launched is given by the following equation: m = M0 × exp (a × v/v0), where M0 is the airship mass, v is the target velocity, v0 is the rocket jet velocity, a is an empirical coefficient, which can typically be taken to be 1.1-1.4, and M is the rocket initial mass. For example, M0 is 1 ton, v0 is 3.5km/s, v is 17km/s, a is 1.3, and the calculated M value is 552 tons. If the value of v is 30km/s, then M can be up to 7 ten thousand tons. If the value of v is 50km/s, then M can reach 1100 million tons. It can be seen that as the speed increases, the value of M increases very rapidly.
The main reason why the rocket has a large mass is that the upper stage can be gradually accelerated only by a large amount of fuel consumed by the lower stage of the multi-stage rocket, and 99% or even more than 99.9999% of energy is used for the acceleration of the rocket itself in the acceleration process. Since the launch of Saturn five before 60 years, the rocket is limited by the limits of chemical fuels and rocket principle, the rocket performance is not greatly improved, the rocket has no potential for improvement, and the airship speed is not substantially improved.
An electromagnetic gun is a device applying an electromagnetic emission technology, and the electromagnetic gun accelerates a bullet by using a magnetic field or ampere force to emit the bullet. The electromagnetic gun can adjust the speed of the gun popping out of the chamber by adjusting the intensity of magnetic field and the intensity of current. The electromagnetic gun generally comprises a plurality of acceleration stages, each acceleration stage generally comprises a speed measuring device, and the discharging speed control is very accurate.
The current strongest electromagnetic guns on the ground have a barrel length of only about 5 meters, but have been able to accelerate the cannonball to 11 km/s. The muzzle speed can be greatly improved by lengthening the barrel, increasing the transmitting power and adopting the superconducting technology in the future, and the muzzle speed can be expected to be improved to 100-300km/s in the future.
Theoretically, a powerful electromagnetic gun can accelerate the airship to a very high speed at one time. However, the airship is large in volume and small in volume weight, is difficult to place in an electromagnetic gun and is extremely difficult to accelerate. The longitudinal section area of the airship is estimated to be not less than 1m ^2, the airship can be accelerated to the electromagnetic gun with the target speed at one time, and the length and the construction cost of the electromagnetic gun are more than 1000 times of those of the common electromagnetic gun. Airships have a large number of complex, delicate components that are difficult to withstand extremely high accelerations. Manned spacecraft, even though acceleration by electromagnetic cannons is never possible.
Another airship accelerating method is to use nuclear reactor to generate electricity and drive ion propeller to generate thrust. However, the thrust generated by the ion thruster hardly exceeds 10N. Moreover, the nuclear power system is heavy, and estimates show that an airship weighing 5 tons will reach 70km/h, and it will take 5-10 years to reach the predetermined speed with nuclear power equipment weighing 5-20 tons and xenon fuel weighing 30 tons. The nuclear power has large energy, but parts such as heat transfer, a turbine, a gas compressor, power generation and the like are easy to wear, gas is easy to leak, and the maintenance is very difficult.

Advantageous effects
The accelerating method is to launch many small-volume and heavy-weight shells by electromagnetic guns, and the airship uses fuel in the shells to accelerate the large-volume and heavy-weight airship. The reason and the advantage of using the electromagnetic cannon to accelerate the airship are as follows:
1) compared with the method for accelerating a pure chemical fuel rocket engine, the airship can be accelerated to 30km/s only by about 15 tons of shells, and can be accelerated to 50km/s only by about 25 tons of shells, so that the cost is saved by thousands to millions of times compared with the chemical fuel rocket.
2) The mass and cost of chemical rockets are increased exponentially by the target speed of the natural logarithm e, the increase speed is extremely high, and therefore the cost is very high when the target speed is more than 20 km/s. The quality and the cost of the electromagnetic gun system are increased according to the multiple of the target speed, and the quality and the cost are not greatly increased during high-speed tasks, so that the electromagnetic gun system is very suitable for the high-speed tasks.
3) The method can reach the target speed within 5-20 hours of acceleration time, and saves thousands of times of time compared with the method of pure nuclear power and ion thrusters.
4) The system is deployed in space, the length of the electromagnetic cannon is not limited by the ground or a carrier, the length of the cannon barrel can be as long as 100 to more than 1000 meters, and the launching speed of the cannon can be greatly improved by increasing the length of the cannon barrel. The electromagnetic cannon can also improve the precision by increasing the magnetic field intensity and the current intensity, the cannonball launching speed can be improved to dozens of km/s, and the cannonball launching speed can be improved to more than 1000km/s in the future, and the potential is extremely great. This is far from comparable to chemical rockets.
5) The system is reusable. If the speed is more than 20km/s, the chemical rocket needs to be divided into 4 grades or even more than 9 grades, and the chemical rocket is very complicated and has poor stability. In addition, since only the 1 st stage can be recovered at most, and the others cannot be recovered, the cost is high. The electromagnetic shell accelerating system can be simply reused, is much more depreciated and has lower manufacturing cost.
In conclusion, the electromagnetic cannonball acceleration system and the acceleration method thereof provide a very good way for future space travel and interstellar flight.
Examples
Example 1
An electromagnetic projectile acceleration system for accelerating an airship in space is deployed at a second Lagrange point of the earth. The system consists of an electromagnetic gun 1, a power supply, communication equipment and a cannonball 2, and operates in space; the cannonball is placed in an electromagnetic cannon to be launched, and the electromagnetic cannon is powered by a power supply. The cannonball is composed of fuel, a shell, communication equipment, an attitude controller and a battery; the fuel is stored in the housing, and is oxygen in a solid state and kerosene in a solid state, so that the fuel can be used for a rocket engine. The launching speed of the electromagnetic cannon is adjustable so as to launch cannonballs with different speeds. The airship is provided with a rocket engine, communication equipment and catching equipment, and the catching equipment can catch shells flying nearby.
When the acceleration method is started, the electromagnetic cannon is aligned with the airship and sequentially launches 6 cannonballs, and the more the cannonball is launched backwards, the higher the speed is.
The cannonball is communicated with the communication equipment of the electromagnetic cannon and the communication equipment on the airship in the flying process, and the flying direction of the cannonball is continuously adjusted. The capturing device is a net, the airship is provided with a net, the length and the width of the net are respectively 5 meters, and the net is vertical to the flying direction. When the cannonball meets the flying boat, the speed difference between the cannonball and the flying boat is less than 5m/s so as to avoid damaging the net by collision. Each projectile catches up with the airship and is captured by the airship. The velocity of the projectile is substantially constant during flight.
The 6 projectiles all weighed 30kg, each with 25kg of fuel, the specific impulse of which was 2000 m/s. The mass of the airship is 1000 kg. For ease of handling, the airship receives one projectile every 300 seconds. The electromagnetic gun is fixed. The firing process of these 6 shells is as follows:
the distance between the 1 st cannonball and the airship is 1000m from the electromagnetic cannon, the two meet at the 10 th s, the speed of the airship relative to the electromagnetic cannon is 100m/s, and the launching speed of the 1 st cannonball is 100m/s, because the two meet at the same speed. Taking the firing moment of the 1 st cannonball as 0s, 10/1=10, and the 1 st cannonball meets the airship at 1000m at the 10 th.
After the airship captures the 1 st cannonball, the fuel in the cannonball is taken out and put into a rocket engine. During the time from 10s to 10+300s, the engine jets backwards, causing the airship to accelerate. The speed of the airship is increased at a constant speed, provided that the thrust provided by the rocket motor is uniform. The first projectile may increase airship velocity by 25kg x 2000m/s/1000kg =50m/s and acceleration is 50m/s/300s =0.16667m/s 2. I.e., 310s, the airship speed was 100+50=150m/s and the distance from the electromagnetic cannon was 1000+100 +300 +0.5 + 0.16667 +300 ^2=38500m when the airship encountered the 2 nd cannon.
Since the speed of the cannonball is the same as that of the airship when meeting and the speed of the cannonball is unchanged during the flying process, the shooting speed of the 2 nd cannonball is 150m/s, the flying time after the cannonball is separated from the electromagnetic cannonball is 38500/150=256.7s, and the shooting time of the 2 nd cannonball is 310-256.7=53.3 s.
Similarly, the 3 rd shell was fired at 192.5s, the firing speed was 200m/s, the time of flight was 417.5s, and encountered the airship at 83500m at 610 s. The 4 th projectile was fired at 336s, at a firing speed of 250m/s and a time of flight of 574s, and encountered the airship at 143500m at 610 s. The 5 th projectile was fired at 481.7s, the firing speed was 300m/s, the time of flight was 728.3s, and the airship encountered at 218500m at 610 s. The 6 th projectile was fired at 628.6s, the firing speed was 350m/s, the time of flight was 881.4s, and encountered the airship at 308500m at 610 s.
The final airship speed was 400 m/s.
The electromagnetic cannon lasts 628.6 seconds from the 1 st to the 6 th cannon. The electromagnetic cannon can be dispersed into a plurality of cannonballs to be shot one by one, so that the volume, weight, power and shooting capability of the electromagnetic cannon can be small-scale, and the economy is improved. If all of the projectiles are fired at once, or if the spacecraft is fired to a target speed at once, the electromagnetic projectiles are necessarily so massive as to be impractical.
Typically, the velocity of each projectile is equal to the velocity of the airship at the point of encounter. The flying time of the cannonball is obtained by dividing the distance between the meeting point and the electromagnetic cannonball by the shooting speed of the cannonball. The time of shooting of the cannonball is obtained by subtracting the flight time of the cannonball from the time of meeting.
Example 2
The other is the same as the previous embodiment except that:
the shell is provided with a spotlight, the spotlight is provided with a spotlight cover, and the light-emitting angle is 2 degrees. The airship 3 is equipped with an optical telescope. In the process of flying the shell to the airship, the optical telescope detects the light of the spotlight and informs the shell to adjust the flying angle. Through the spotlight and the telescope, the airship can detect shells of hundreds of kilometers and even tens of millions of kilometers away, the success rate of receiving the shells is greatly improved, the number of the shells is saved, and the energy consumption of the electromagnetic cannon is reduced.
The length of the gun barrel of the electromagnetic gun is 20 meters, the weight of the gun barrel is 50 tons, the maximum launching speed is 20km/s, the power supply of a power supply is 2 ten thousand kw, and the electromagnetic gun runs on the second Lagrange point of the earth. At the 0 th second time, the airship was 2000km from the electromagnetic cannon, the speed being 10 km/s.
The electromagnetic cannon 1 needs to shoot 110 cannonballs, and the mass of each cannonball 2 is the same and is 30 kg. The interval of time the airship receives the shells is increasing from the 1 st to the last shell. The time interval of the 1 st and 2 nd shells is 300s, the time interval of the latter shell is 1.005 times of the former shell, the time interval of the 2 nd and 3 rd shells is 301.5s, and the time interval of the 109 th and 110 th shells is 516.7 s. The time interval of the firing is larger and larger, the time interval of the 1 st cannonball and the 2 nd cannonball is 3.12s, the time interval of the 2 nd cannonball and the 3 rd cannonball is 5.73s, the time interval of the 3 rd cannonball and the 4 th cannonball is 8.23s, and the time interval of the 109 th cannonball and the 110 th cannonball is 152.5 s. The later the transmission time interval is larger, the charging power requirement can be reduced, and the electromagnetic gun and the power supply do not need to be too large in scale.
Because the time interval of the transmission is larger and larger, the task can be completed only by a power supply and the electromagnetic cannon with lower power although the power requirement of the electromagnetic cannon is not too high in the later period.
In the acceleration method, the electromagnetic gun works for 2.68 hours, and the maximum charging power is 7.8 ten thousand kilowatts. The launching speed of the 110 th cannonball is 19000m/s, the cannonball meets the airship 3 after 9.4 hours after launching, and the meeting point is 67 km away from the electromagnetic cannonball. The consumed projectiles amounted to 3.3 tons, accelerating the airship to 19 km/s. If a normal rocket is used, the initial weight of the rocket is more than 1000 tons.
Example 3
In example 1, the airship 3 receives the shells at the same time interval and the weight of the shells is the same. The electromagnetic cannon is a device for converting kinetic energy of a power supply into kinetic energy of a cannonball, and the power of the power supply is limited. The charging power is the average power of the electromagnetic gun when charged in two emission intervals, and obviously, in the last embodiment, the charging power of each time interval is larger and larger. The more the cannonball is shot backwards, the higher the speed is, the larger the kinetic energy of the cannonball in unit mass is, and the later period puts high requirements on charging power. The rest is the same as example 1 except that:
the length of the gun barrel of the electromagnetic gun is 500 meters, the weight of the gun barrel is 2000 tons, the maximum launching speed is 60km/s, the power supply of a power supply is 20 ten thousand kw, and the electromagnetic gun runs on the second Lagrange point of the earth. At the 0 th second time, the airship was 2000km from the electromagnetic cannon, the speed being 10 km/s.
The electromagnetic cannon 1 needs to shoot 800 cannonballs 2. The shells have smaller and smaller masses from the beginning of the firing of the 1 st to the last shell. The mass of the 1 st shell is 30kg, the mass of the 2 nd shell is 0.999 times that of the 1 st shell, the mass of the 3 rd shell is 0.999 times that of the 2 nd shell, and so on, and the mass of the 800 th shell is 13.49 kg.
The interval of time the airship receives the shells is increasing from the 1 st to the last shell. The time interval for the 1 st and 2 nd shells is 300s, the latter time interval is 1.0005 times the former, the time interval for the 2 nd and 3 rd shells is 300.15s, and the time interval for the 799 th and 800 th shells is 447 s. The time interval of the firing is larger and larger, the time interval of the 1 st cannonball and the 2 nd cannonball is 3.12s, the time interval of the 2 nd cannonball and the 3 rd cannonball is 5.71s, the time interval of the 3 rd cannonball and the 4 th cannonball is 8.23s, and the time interval of the 799 th cannonball and the 800 th cannonball is 133 s.
The more backward transmission time interval is larger, the cannonball quality is smaller and smaller, the arrangement can reduce the requirement of charging power, the scales of the electromagnetic cannonball and the power supply do not need to be too large, in the whole accelerating method process, the charging power is more balanced, and the resource utilization rate is high.
In the acceleration method, the electromagnetic gun works for 27.3 hours, and the maximum charging power is 18 ten thousand kilowatts. The firing speed of the 800 th cannonball is 59000m/s, the cannonball meets the airship after 54.5 hours after firing, and the meeting point is separated from the electromagnetic cannon 1170 for ten thousand km. The consumed projectiles amounted to 16.5 tons, accelerating the airship to 59 km/s. If a normal rocket is used, the initial weight of the rocket is more than 1 million tons.
Example 4
The other is the same as the previous embodiment except that:
the electromagnetic cannon is mounted foremost, then the generator, and finally the gas turbine. A 30 m long exhaust pipe is installed behind the gas turbine, and a gas vane is installed at the rear end of the exhaust pipe. The longer exhaust pipe makes the exhaust be difficult to infect the electromagnetism big gun work.
An infrared telescope with the diameter of 1 meter is arranged on the electromagnetic gun. The spotlight for the cannonball is an LED lamp with a peak wavelength of 100-1000um, a power of 0.1w, a diameter of 0.2cm and a light emission angle of 2 degrees. In the process of flying the cannonball away from the electromagnetic cannon, an optical telescope of the electromagnetic cannon detects the light of a spotlight and informs the cannonball to adjust the flying angle. The distance between the electromagnetic cannon and the airship is a, and when the distance between the cannonball and the electromagnetic cannon is less than 0.8a, the spotlight of the cannonball faces the electromagnetic cannon, so that the observation of the electromagnetic cannon is facilitated. When the distance between the cannonball and the electromagnetic cannon is more than 0.8a, the spotlight of the cannonball is opposite to the airship, so that the observation and correction of the airship are facilitated.
And the communication equipment of the cannonball can emit electromagnetic waves, and the distance between the cannonball and the airship and the distance between the cannonball and the electromagnetic cannon can be known in real time by calculating the time of the electromagnetic waves. By analyzing the spotlight and the distance of the cannonball, the spatial position of the cannonball can be accurately known.
The electromagnetic gun is provided with a rocket engine, and the air injection direction of the rocket engine is opposite to the flying direction of the cannonball, so that the electromagnetic gun cannot move backwards in continuous work. The power source is a gas turbine and a generator, the gas turbine using liquid oxygen and kerosene fuel. The jet direction of the exhaust pipe of the gas turbine is opposite to the flying direction of the cannonball.
The system is deployed at a second lagrangian point on earth. The system does not revolve around the earth, and can keep the direction of the electromagnetic gun unchanged for a long time.
