Chapter 742 New breakthrough in the laboratory

He is also really curious. To know that he has handed over most of the work of the laboratory to Kuafu for operation, and also extended this good thing to all the laboratories of the entire company. The vast majority of hands-on and very boring repetitive experiments and long-term observation experiments can all be left to the origin to do.

With the successful delivery of the second-generation robot customized by the robot laboratory for the laboratory, now the company's laboratory is basically very few people have to stay at night to work overtime, because most of the work robots can be completed.

"Oh, this is the boss. Today, the deep space laboratory is going to experiment with a new ion engine. The performance has been very good, so everyone is looking forward to its final test results, about 7 o'clock in the evening. All the test results will come out in a lot of time, so we think it is better to wait.

Anyway, it’s not too late to go home after reading the data at more than 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, rather than sending us the origin after returning home. A dry test data!Fang Huiran smiled and explained why they stayed overtime.

"I have to take a look at this, let's go, let's go together!" Hearing this, Lei Tiantang's interest also came.

You have to know that the Firefly 1 and Firefly 2 Mars orbiting satellites launched by Infinite Gravity Group have been launched for several months. So far, they have not flew to Mars. Why?

It is not that the acceleration time of the ion engine propulsion system that comes with the satellite is too long. This is 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 fast. .

Ordinary satellites to Mars and landing detectors will not boost acceleration during flight, but choose to use the planet's gravitational slingshot effect to accelerate, the speed can be imagined slow.

Deep space exploration is an important application area of ​​spacecraft, and propulsion technology is an important factor restricting spacecraft deep space exploration capabilities.Deep space exploration missions have led to the development of multiple propulsion technologies. Advances in propulsion technology have also provided more options for the expansion of deep space exploration missions.

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

From the point of view of the detection object, within the solar system, the detection range includes all kinds of substances and phenomena such as various planets, satellites, comets, etc., and outside the solar system, there is a vast cosmic space.

From the perspective of detection methods, common methods include orbit inspection, crossing detection, braking landing, and sampling return. The requirements for spacecraft and propulsion systems for different detection methods vary greatly.

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

First, the propulsion system is required to have a high specific impulse.Deep space exploration tasks need to get rid of the gravity of various stars, which requires the detector to have a higher speed increment, and this speed increment has two channels to obtain: one is provided by the interplanetary flight, the other It is provided by the propulsion system that comes with the spacecraft.

The former needs to meet many constraints and is often at the expense of more time; the latter requires a higher total charge for the propulsion system. In the case of limited launch weight and restricted propellant carrying capacity, the total charge Improvement can only be achieved by higher specific impulse.

Secondly, the propulsion system is required to provide proper thrust.For tasks that require fast orbit adjustment, rapid braking, controlled landing on the detected object, or need to take off and return after sampling, the spacecraft can provide enough thrust to meet the requirements of the above detection mission. The required thrust is determined according to the mission characteristics and gravity.

Thirdly, the propulsion system is required to have a certain adaptability to energy.Many deep space exploration missions will have a large change in the distance between the spacecraft and the sun during the entire detection 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 requirements, deep space exploration spacecraft propulsion systems are often composed of multiple types. In different working stages, different propulsion technologies are used to enable them to maximize their advantages.

But if the performance of the company’s ion engine can be greatly improved, it will bring better changes to the company’s future solar system exploration plan, so Lei Tiantang only thought of Fang Huiran when he said this matter. Take a look.

"Okay, but what about Xiaoqing?" Fang Huiran asked, looking at a few dogs who were impatient just after stopping to say a few words.

"It's not urgent anyway. We went shopping together. You just eat and drink, just go to the laboratory and hand them over to the security staff. Just take them back when I'm gone!" Lei Tiantang ripped. The straight rope pulled in all directions from his hand laughed.

Along the way, Lei Tiantang did not specifically ask about the engine. He didn’t see the real thing and knew the data, and he didn’t have an intuitive impression. So after a little chat, he arrived at the deep space laboratory. After Kazakhstan handed it over to the security staff, the two went into the dedusting room to remove the dust, and then put on the laboratory special clothes and entered the laboratory together.

"Yeah, boss, here you come!" Zhang Han revised what he said to the researcher in front of the experimental bench. He saw his boss coming and smiled and said hello.

"Well, I met Director Fang outside the cafeteria. Hearing you said that you are working overtime to test the new ion engine. I thought about coming over to see the situation. Tell me about it?" Lei Tiantang waved with a smile Said with a wave.

"Haha! It seems that you can't experience this surprise boss, I still plan to wait for the test data to come out, and its performance fully meets the requirements before going to thank you!

To know that for this ion engine, the laboratory has been busy for a long time, all kinds of dissatisfaction, all kinds of modified designs, if we have not made a breakthrough in the design recently, I 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 probe, Saturn probe and the more distant probes that we have not yet launched will reduce the flight time by at least half!"
