He is also really curious, knowing that he himself has delegated most of the work of the laboratory to Kuafu to operate, and has also extended this good thing to all the laboratories of the entire company. The most important contribution of scientific researchers is still the brain. Now Most of the hands-on and very boring repeated experiments and long-term observation experiments can all be done by the origin.

With the smooth delivery of the second-generation robots customized by the Robotics Lab for the laboratory, few people in the company's laboratory have to stay at night to work overtime, because most of the working robots can be completed.

"Oh, it is such a boss. Today, the Deep Space Laboratory is going to experiment with a new ion engine system-wide. It has performed very well so far, so everyone is looking forward to its final test results, about 7 pm All the test results will be available when there are too many, so we think it is better to wait.

Anyway, it’s not too late to go home after reading the data at 7 o’clock. After all, this engine is related to our company’s future deep space exploration plan. Everyone hopes to confirm its performance earlier, instead of waiting for the origin to send us back home. A dry test data! Fang Huiran smiled and explained why they stayed to work overtime.

"I have to see this, let's go, let's go together!" Hearing that this was the case, Lei Tiantang's interest also came.

We must know that the "Firefly 1" and "Firefly 2" Mars orbiting exploration satellites launched by 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 satellite’s own ion engine propulsion system is too long. It’s because the rocket load of the Infinite Gravity Group is large, so the satellite can carry more fuel and a few more ion engines. The speed is already considered fast. .

General satellites sent to Mars and landing probes will not boost acceleration during the flight, but choose to use the planet's gravitational slingshot effect to accelerate, the speed is conceivably slow.

Deep space exploration is an important application field of spacecraft, and propulsion technology is an important factor that restricts spacecraft's deep space detection capabilities. Deep space exploration missions have led to the development of a variety of propulsion technologies, and advances in propulsion technology have also provided more options for the expansion of deep space exploration missions.

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

From the point of view of objects to be detected, within the solar system, the detection range includes all types of planets, satellites, comets, and other substances and phenomena. Outside the solar system, there is a vast universe.

From the perspective of detection methods, common methods include circumnavigation, crossing 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, a summary of these missions can extract the common requirements for spacecraft propulsion systems of this type of mission.

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

The former needs to meet many constraints and often costs more time; the latter requires the propulsion system to have a higher total impulse. When the launch weight is limited and the amount of propellant carried is restricted, the total impulse is Improvement can only be achieved by relying on a higher specific impulse.

Secondly, the propulsion system is required to provide suitable thrust. For tasks that require rapid orbit adjustment, rapid braking, controlled landing on the detection object, or take-off and return after sampling, the spacecraft needs to provide sufficient thrust to meet the requirements of the above detection tasks. The amount of thrust required is determined according to the characteristics of the task and the gravitational situation.

Third, the propulsion system is required to have a certain adaptability to energy. For many deep space exploration missions, the distance between the spacecraft and the sun will change significantly during the entire exploration cycle. For propulsion systems that rely on external energy, especially solar electric propulsion systems, they must have the ability to adapt to energy changes so that the engine can It can work normally in different power ranges.

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

But if the company’s ion engine performance can be greatly improved, it will bring better changes to the company’s future solar system exploration plans, so Lei Tiantang only thought about it when Fang Huiran said it. Go take a look.

"Okay, but what about Xiaoqing?" Fang Huiran asked with a smile looking at a few impatient dogs who just stopped to say a few words~lightnovelpub.net~ Anyway, it's not in a hurry, let's be together Walk over, you just need to digest them, just hand them to the security personnel at the laboratory, and just take them back when I leave! "Lei Tiantang pulled the straight rope pulled from all angles and smiled.

Along the way, Lei Tiantang did not specifically ask about the engine, did not see the actual object, know the data, and had no intuitive impression, so after a little chat, he came to the Deep Space Laboratory, and put a few more energetic two. After handing it to the security personnel, the two of them went into the dust removal room to remove dust, and then put on the special laboratory clothes and entered the laboratory together.

"Yeah, boss, you are here!" Zhang Han corrected what he said to the researcher next to him in front of the experimental platform, and smiled and said hello when he saw his boss came.

"Well, I met Director Fang outside the cafeteria and heard him say that you are working overtime to test the new ion engine. Why don't I just want to come over to see the situation and tell me about the situation?" Lei Tiantang smiled and waved Waved his hand and said.

"Haha! It seems that you won't be able to experience this surprise boss. I still plan to wait for the test data to come out and its performance fully meets the requirements before I will tell you the good news!

We must know that for this ion engine, the laboratory has been busy for a long time, all kinds of dissatisfaction, various modifications and designs, if we have not made a breakthrough in design recently, we still don't know when we can get it done!

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