I Have a Little Black Hole

He is also really curious, to know that he has handed over most of the work in the laboratory to Kuafu, and has also extended this good thing to all the laboratories of the company. The most important contribution of scientific researchers is to think out. Now Most of the repetitive experiments and long-term observation experiments that require hands-on and very boring can be handed over to Origin.

With the smooth delivery of the second-generation robot specially customized for the laboratory in the robot laboratory, there are basically few people in the company's laboratory who have to stay at night to work overtime, because most of the working robots can be completed.

Oh, that's the boss. Today, the Deep Space Laboratory is going to test a new ion engine for the whole system. It has performed very well so far, so everyone is looking forward to its final test results, about 7 o'clock in the evening. All the test results will be available in a lot of time, so we think it's better to wait.

Anyway, it's not too late to go home after reading the data at 7:00. After all, this engine is related to our company's future deep space exploration plan. Everyone hopes to confirm its performance earlier, rather than waiting for the origin to send us a message after returning home. A dry test data! Fang Huiran smiled and explained why they stayed to work overtime.

I have to go and see this, let's go, let's go together! Hearing this, Lei Tiantang's interest also came.

You must know that the 'Firefly 1' and 'Firefly 2' Mars orbiting exploration satellites launched by the Infinite Gravity Group have been launched for several months, and they have not yet flown to Mars. Why?

It's not that the acceleration time of the ion engine propulsion system that comes with the satellite is too long. It's still the rocket load of the Infinite Gravity Group, so the satellite can carry more fuel and a few more ion engines, and the speed is already fast. .

Ordinary satellites sent to Mars and landing probes will not be boosted and accelerated during flight, but choose to use the planet's gravitational slingshot effect to accelerate, which is conceivably slow.

Deep space exploration is an important application field of spacecraft, and propulsion technology is an important factor restricting the deep space exploration capability of spacecraft. Deep space exploration missions have led to the development of a variety of propulsion technologies, and the advancement of propulsion technologies has also provided more options for the expansion of deep space exploration missions.

Due to the diversity of deep space exploration in terms of object selection and detection methods, its requirements for propulsion systems are also diverse.

From the perspective of detection objects, within the solar system, the detection range includes all kinds of planets, satellites, comets and other substances and phenomena. Outside the solar system, there is a vast cosmic space.

From the perspective of detection methods, common methods include circumnavigation, traversal detection, braking landing, sampling return, etc. Different detection methods have very different requirements for spacecraft and propulsion systems.

Despite the diversity of deep space exploration missions, summarizing these missions can extract the common requirements for spacecraft propulsion systems of such missions.

First, the propulsion system is required to have a high specific impulse. Deep space exploration missions need to get rid of the gravitational force of various stars, which requires the detector to have a high speed increment, and there are two channels for this speed increase: one is provided by the leveraged flight between planets, the other It is provided by the propulsion system that comes with the spacecraft.

The former needs to meet many constraints, often at the cost of more time; the latter requires the propulsion system to have a higher total impulse. Under the circumstance that the launch weight is limited and the propellant carrying capacity is restricted, the total impulse is limited. The improvement can only be achieved by means of a higher specific impulse.

Second, the propulsion system is required to provide suitable thrust. For tasks that require fast orbit adjustment, fast braking, controlled landing on the detection object, or take-off and return after sampling, the spacecraft needs to provide enough thrust to meet the above detection tasks. The required thrust is determined according to the characteristics of the mission and the gravitational conditions.

Third, the propulsion system is required to have a certain adaptability to energy.

During the entire exploration cycle of many deep space exploration missions, the distance between the spacecraft and the sun will change greatly. For propulsion systems that rely on external energy, especially solar-electric propulsion systems, they must have the ability to adapt to changes in energy, so that the engine can It can work well in different power ranges.

In order to meet the above requirements, the propulsion system of deep space exploration spacecraft is often composed of various types. In different working stages, different propulsion technologies are used to enable them to exert their greatest advantages.

But if the performance of the ion engine on the company's side can be greatly improved, it will bring better changes to the company's future solar system exploration plan, so Lei Tiantang only thought about it when he heard Fang Huiran talking about it. Check it out.

Okay, but what about Xiaoqing and the others? Fang Huiran asked with a smile, looking at the impatient dogs who had just stopped to say a few words.

Anyway, we're not in a hurry. Let's go shopping together. You're just in the process of digesting food. Just go to the laboratory and hand them over to the security staff. Just take them back when I leave! Lei Tiantang snorted. The straight rope pulled at every angle in his hand laughed.

On the way, Lei Tiantang didn't ask any specific questions about the engine, and he didn't see the real thing and knew the data, and he didn't have an intuitive impression, so after chatting for a while, he went to the deep space laboratory, and put a few of the energetic two. After Ha handed it over to the security personnel, the two entered the dust removal room together to remove dust, and then changed into special laboratory clothes and entered the laboratory together.

Hey, boss, you're here! Zhang Hanxiu said something to the researcher next to him in front of the experimental bench, and greeted him with a smile when he saw his boss coming.

Well, I met Director Fang outside the cafeteria, and I heard that you were working overtime to test the new ion engine. I just wanted to come over to check the situation and tell me the situation? Lei Tiantang waved with a smile. waved his hand and said.

Haha! It seems that you can't experience this surprise boss. I plan to wait for the test data to come out, and its performance fully meets the requirements before I will announce the good news to you!

You must know that for this ion engine, the laboratory has been busy for a long time, with various dissatisfaction and various design modifications. If we have not made a breakthrough in design recently, I still don’t know when it will be done!

If the performance of this ion engine is tested and meets our design requirements, then the Jupiter, Saturn, and more distant probes that we have not yet launched will reduce the flight time by at least half!
