Abstract

Accelerating an airship in space to more than 20km/s relative to earth requires the consumption of a lot of fuel, and fuel consumption increases exponentially with the increase of the target speed. The invention provides an accelerating system consisting of an electromagnetic cannonball and a cable transfer system and an accelerating method thereof. The cannonball is launched by an electromagnetic cannon in space, captured by a cable rotating system and separated after rotating 180 degrees around the rotation center. The transfer cable system can obtain forward impulse and gradually increase the speed of the airship by the method. The electromagnetic cannon emits dozens of hundreds of cannonballs, and the airship receives the cannonballs in turn in the acceleration process, so that the acceleration is carried out step by step. The acceleration method consumes less fuel and plays a wide and very important role in future space travel.

Description

Acceleration system consisting of electromagnetic cannonball and cable transfer system and acceleration method thereof

Technical Field

The invention relates to the technology of space, rocket engine, chemical fuel, electromagnetic cannon, orbit, telescope, spotlight, manipulator, cable-rotating system, 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 1.1-1.5, and M is the rocket initial mass. For example, M0 is 1 ton, v0 is 3.5km/s, v is 20km/s, a is 1.3, and the calculated M value is 1683 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.

The large rocket mass is mainly caused by the fact that the upper stage can be gradually accelerated by a plurality of stages of rockets and a large amount of fuel consumed by the lower stage. 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, 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 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.

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 is difficult to exceed 10N, and the acceleration is small, which takes 5-10 years to reach the predetermined speed. 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.

The cable-winding system is composed of a counterweight, a cable, and a capturing device, wherein the capturing device is tied at the tail end of the cable, and the capturing device and the cable rotate around a rotation center. The mass center of the cable rotating system flies linearly and the cable rotating system rotates. The point where the linear velocity of the capturing device is the same as the flight direction of the center of mass is called the co-directional point of the capturing device. The point at which the linear velocity of the capture device is opposite to the direction of flight of the centroid is referred to as the reverse point of the capture device. In each cycle, the capture device passes through a point of co-rotation and a point of counter-rotation. Different objects A, B on the same side of the center of rotation, if A is at the same directional point of A, then B is also at the same directional point of B. If the cable-rotating system flies straight, the connecting line of the equidirectional points of different periods of the capturing device is a straight line. The capture device can receive the aircraft as long as it is at the same point or the opposite point.

Advantageous effects

The accelerating system and the accelerating method consisting of the electromagnetic cannonball and the cable transfer system launch numerous cannonballs with small volume and weight through the electromagnetic cannonball, and the airship uses fuel in the cannonball to accelerate the airship with large volume and weight. The reason and the advantage of using the electromagnetic cannon to accelerate the airship are as follows:

1) compared with a method for accelerating a pure chemical fuel rocket engine, the airship can be accelerated to 30km/s only by 6 tons of shells, and can be accelerated to 50km/s only by about 10 tons of shells, so that the cost is saved by thousands to tens of millions of times compared with the chemical fuel rocket.

2) The projectile is received by the turret system and is separated from the turret system after half a revolution about the centre of rotation. If the linear velocity is v and the projectile mass is m, the mooring system and the airship can be caused to increase by 2mv of impulse, corresponding to 2v of equivalent specific impulse of the projectile. Generally, v can reach more than 3km/s, correspondingly, the equivalent specific impulse can reach more than 6km/s, which is much higher than that of the common chemical fuel. Because of large specific impulse, the cannonball consumes less energy, and the electromagnetic cannon also consumes less energy.

3) 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.

4) 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.

5) 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.

6) The acceleration 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 cost is high because only the 1 st grade can be generally recovered at most and the others cannot be recovered. The electromagnetic shell accelerating system can be simply reused, is much more depreciated and has lower manufacturing cost.

In conclusion, the acceleration system consisting of the electromagnetic cannonball and the cable transfer system and the acceleration method thereof provide a very good way for the future space tourism and interstellar flight.

Examples

Example 1

An acceleration system and an acceleration method thereof are disclosed, which are used for accelerating an airship.

The accelerating system consists of an electromagnetic gun 1, a shell 2 and a cable transfer system 3, and is deployed on a second Lagrange point of the earth;

the shell consists of a shell body, radio communication equipment, a spotlight, an attitude controller and a battery, wherein the battery supplies power to the radio communication equipment and the attitude controller. The cannonball is placed in the electromagnetic cannon to be shot. The body is made of aluminum alloy and has a mass, so that the impulse can be increased for the cable-winding system. The launching speed of the electromagnetic cannon is adjustable so as to launch cannonballs with different speeds. The cable-rotating system is provided with communication equipment and a capturing device, wherein the capturing device is a mechanical arm and can capture shells flying to the same direction point.

The airship 6 is installed in a transfer system 3, which is composed of an airship, a cable 5, and a capturing device 7. The weight of the ship is 800kg, and the total weight of the cable transfer system is 1000 kg. The flying boat is tied with a cable, the other end of the cable is connected with a capturing device, and the capturing device and the flying boat are respectively arranged at two ends of the rotation center. The cable and the catch rotate about the airship's centroid 4. The cable rotating system flies forwards and rotates, and the rotation axis is perpendicular to the direction of the horizontal flying. Therefore, the connecting line of the equidirectional points 8 is a straight line. The rotation period of the cable-rotating system is 1 second, the linear speed of the capture device rotating around the mass center is 1km/s, and the rotation radius of the capture device is 0.159 km.

The projection of the centroid of the cable-rotating system on the same-direction point connecting line is called the distance and the relative speed of the cable-rotating system with the electromagnetic gun respectively. Generally, since the cable diversion system is far from the electromagnetic cannon and the cable is short, the distance and the speed of the mass center relative to the electromagnetic cannon are respectively equal to the distance and the speed of the cable diversion system.

When the acceleration is started, the homodromous point of the capture device is in front of the electromagnetic cannon, and the electromagnetic cannon is on the homodromous point connecting line. The electromagnetic gun is aligned with the same directional point of the capturing device and sequentially launches 3 shells, and the more backward the shooting speed of the shells is, the higher the shooting speed is. Each shell flies forwards and meets the cable transfer system, and the shells are captured by the capturing devices at the same directional point. The projectile is then thrown at the reversal point 9 after the catch means has been turned through 180 degrees. The weight of these 3 projectiles was 30 kg.

At the 0 th second moment, the speed of the mass center of the cable-transferring system relative to the electromagnetic gun is 1km/s, the speed of the mass center of the cable-transferring system is 100km away from the electromagnetic gun, and the capturing device is at the same directional point. Thus, when the time is an integer number of seconds, the capture devices are all at the same point. The 1 st shell is shot by the electromagnetic gun at the shooting speed of 2km/s, and the speed of the shell relative to the cable transfer system is 1 km/s. The cannonball meets the transfer cable system about 100 seconds, which is 200km away from the electromagnetic cannon. The projectile encounters the mooring system with a velocity of 0 relative to the catching device and at the same point and can thus be caught by the catching device. After the cannonball rotates 180 degrees around the mass center, the cannonball is thrown out by the capture device when the cannonball reaches a reverse point. The projectile is thus detached backwards with respect to the airship, also at a speed of 3km/s with the cable system. In this process, the cabling system increased forward momentum by 30 x 1 x 2=60kg.km/s, and the speed increase of the cabling system was 60/1000=0.06km/s, becoming 1.06 km/s.

The 2 nd projectile was fired at 50 seconds with a firing rate of 2.06km/s, and the linear velocity of the projectile relative to the center of mass at docking was also 1 km/s. The cannonball encounters the airship at about 197 seconds, at which point it is 302.82km from the electromagnetic cannon. The cannonball is provided with a jet engine, and the speed of the cannonball is adjusted by the jet before the cannonball is caught by the catching device, so that the cannonball can be butted. After the transfer cable system is thrown away from the 2 nd cannonball, the flat flying speed of the transfer cable system becomes 1.12 km/s.

Example 2

The other is the same as the previous embodiment except that:

and a 3 rd cannonball is also launched in the task, and the launching speed of the 3 rd cannonball is 1.12+1=2.12 km/s. The predetermined 3 rd cannonball meets the cable-transfer system at the 400 th second, and the cable-transfer system is 302.82+ (400-197) = 530.18km away from the electromagnetic cannonball. Assuming that the 3 rd cannonball is shot at the time t, 2.12 x (400-t) = 530.18 can be obtained according to the distance relation, and t is 149.9 seconds. The linear velocity of the 3 rd projectile at docking is also 1km/s relative to the centre of mass, while the receiving device is at the same point and is therefore able to receive the projectile. Likewise, the 3 rd cannonball increases the flat velocity of the transfer cable system to 1.18 km/s.

The electromagnetic cannon lasts 149.9 seconds from the 1 st to the 3 rd 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.

Each projectile can increase the flat velocity of the transfer cable system by a determined value, so that the firing speed of the next projectile can be determined, namely equal to the flat velocity obtained by the transfer cable system after the previous projectile is used. Assuming that the ith projectile is captured such that the horizontal flying velocity of the transfer cable system is increased to vi, the firing velocity of the (i + 1) th projectile is vi. And solving an equation can obtain the meeting point of the i +1 th cannonball and the junction of the transfer cable system according to the time for receiving the i th cannonball, the distance from the electromagnetic cannonball and the i +1 th cannonball launching speed, and further backward deducing the launching time.

Example 3

The rest is the same as example 1 except that:

the 3 rd projectile was equipped with a rocket engine, which was one of the jet engines. The 3 rd projectile was fired at 100 seconds with a firing rate of 2.12km/s, and the linear velocity of the projectile relative to the center of mass when docked was also 1 km/s. The projectile is expected to meet the transfer cable system at 294.18 seconds. Since the capture device is not at the same directional point at 294.18 seconds and cannot receive the cannonball, the capture device meets at 294 seconds instead, and the cable diversion system is away from the electromagnetic cannon 302.82+ (294 and 197) 1.12=411.46 km. For this purpose, the 3 rd projectile was fired during flight by its rocket motor, ejected backwards, increasing the projectile velocity by 0.1km/s for t seconds, and then fired again for ejecting the forward jet, returning the projectile velocity to 2.12 km/s. Then there is the equation (294-. The cannonball is then met in a cabled system at 411.46km from the electromagnetic cannon, 294 seconds, when the receiving apparatus is at the same point, and is therefore able to receive the cannonball.

In a general task, an electromagnetic gun needs to emit dozens or even hundreds of shells, and due to prediction errors, control errors and observation errors, the shells can not fly to the same-direction point as expected, or the capturing devices are not in the same-direction point at the same time. The cannonball is provided with a jet engine, and the flying speed can be adjusted when the cannonball is close to a cable rotating system, so that the cannonball can be guaranteed to be caught at a certain equidirectional point. Even if the rotation period of the cable rotating system is as high as 10 seconds, the method is also suitable, and the success rate of the catching device for catching the cannonball can be greatly improved.

Example 4

The rest of this embodiment is the same as embodiment 1, except that:

the shell is provided with a spotlight which is an LED lamp provided with a reflecting cover, and the light-emitting angle is less than 2 degrees. The electromagnetic gun is provided with a telescope, and the diameter of the telescope is 2 meters. During flying off the electromagnetic cannon, the telescope monitors the flying direction of the cannon, the cannon is informed through radio, and the cannon adjusts the flying direction of the cannon through the attitude controller.

The cable-rotating system is provided with a rotary table which is arranged on a cable at the rotating center. The axis of the turntable is parallel to the axis of rotation of the cable system. The rotary table is provided with a telescope and a radar. In this way, although the cable rotating system continuously rotates, the rotary table enables the telescope and the radar to be aligned to the rear, and the cannonball is continuously observed backwards. When the cannonball is near hundreds of km and tens of thousands of km of the cable-rotating system, the telescope on the revolving platform can observe the spotlight of the cannonball, thereby informing the cannonball to adjust the flying party by radio.

The posture controller of the cannonball enables the spotlight of the cannonball to irradiate forwards or backwards, and the irradiation direction is stabilized. The 2 nd revolving platform has been installed to the outer end of the revolving platform of hawser end, has installed the telescope on the 2 nd revolving platform, and the revolving platform makes the directional continuation of telescope in the rotation plane of cable system. When the telescope is at the same direction point, the shell is observed backwards, and the flying direction of the shell is adjusted, so that the shell can fly by aligning with the same direction point of the cable. In space, a fixed star right behind the mass center is used as correction reverse direction, and the telescope only needs to observe the angle of the cannonball deviating from the fixed star, so that the deviation condition of the cannonball can be detected, and the flight of the cannonball is guided. Meanwhile, the distance of the cannonball can be judged by measuring the radio receiving and sending time.

In a practical one-time acceleration method, an electromagnetic cannon may shoot dozens of cannonballs and hundreds of cannonballs, and the cannonballs may fly millions of kilometers before meeting with a cable transfer system. Typically, a telescope with a diameter of 2 meters can observe a spotlight beyond 1 hundred million km. The cannonball is provided with the spotlight, the cable transfer system and the electromagnetic cannonball are provided with the telescope, and the success rate of capturing the cannonball by the cable transfer system in deep space can be greatly improved.

Example 5

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 electromagnetic gun of the acceleration system is 500 meters in length. In the acceleration method, the linear velocity of the cable-winding system is 3km/s, and the equivalent specific impulse of each cannonball is 6km/s, which is far higher than any chemical fuel. The electromagnetic gun needs to emit 500 shells. Wherein the weight of the 1 st to 300 th cannonball is 30 kg. The projectile mass is smaller and smaller from the 301 st projectile 2 to the last projectile, the mass of the last projectile being 5 kg. The time interval for the electromagnetic cannon to fire the cannonball is larger and larger from the 1 st cannonball to the last cannonball. The interval between the 1 st and 2 nd shells is 50 seconds, the interval between the 2 nd and 3 rd shells is 51 seconds, and the interval between the 499 nd and 500 th shells is 200 seconds.

In the acceleration method, the electromagnetic gun works for 20 hours, and the maximum charging power is 20 ten thousand kilowatts. The launching speed of the 500 th cannonball is 63km/s, the cannonball meets the airship after 30 hours after launching, the meeting point is separated from the electromagnetic cannon 1170 for ten thousand km, and finally the airship is accelerated to 60 km/s. The total weight of the transfer cable system (including airship) was 1 kinetic energy, the projectile capture success rate was 95%, and the consumed projectiles were 1 × 60/6/0.95=10.5 tons. If a general rocket is used, the initial weight and fuel consumption of the rocket are more than 1 million tons.

The more the later the firing interval is, the smaller the projectile mass becomes, and this arrangement can reduce the charging power requirements so that the electromagnetic cannon and power supply do not need to be too large in scale. In the whole accelerating method process, the charging power is relatively balanced, and the resource utilization rate is high. If the interval for later-period shooting of the shells is short and the mass of the shells is also large, the requirement on the shooting capability of the electromagnetic gun is high.

The airship is always mounted on the opposite side of the centre of rotation to the cable, that is: the catch is at one end of the cable and the airship is at the other end of the cable. After the catching device is connected with the last cannonball, when the cannonball turns to the reverse point, namely the airship is at the same direction point, the airship is separated from the cable and flies forwards. At this time, the airship is able to obtain a forward linear velocity, and a velocity after disengagement is relatively high.

The electromagnetic gun is provided with a rocket engine, the jet direction of the rocket engine is opposite to the flying direction of the cannonball, and forward thrust can be generated during working to prevent the electromagnetic gun from retreating. The power supply of the electromagnetic gun is a gas turbine and a generator, and the gas turbine uses liquid oxygen and kerosene or liquid oxygen and liquid hydrogen as fuels. The exhaust direction of the gas turbine is opposite to the flying direction of the cannonball.

The system is deployed on the second Lagrange point of the earth, and the system does not revolve around the earth and can keep the direction of the electromagnetic gun unchanged for a long time.
