Three hours later, Sirius' gradual deceleration caused the spacecraft to be captured by the planet's gravity and successfully enter orbit around Straw. The spacecraft is now in a calculated critical orbit that can be accelerated at any time beyond the first cosmic velocity of Straw Star and out of the effective range of the planet's gravity.

What Su Zhao has to do now is to use the detection function of the host to preliminarily collect some important parameters of the planet, judge whether it can meet his own living conditions, and then determine whether to reduce the orbital altitude to collect more detailed planetary surface data, and now because Straw Star has reached the upper limit of the atmosphere of 4500km, it is not possible to effectively obtain planetary surface image data.

"Host, keep the current orbit, analyze the planetary atmosphere data, and generate an atmospheric analysis report for me."

"Atmospheric data is being collected, and real-time analysis is being carried out...... The spectral data detection is completed, and the atmospheric structure is in the middle of the layering...... The analysis report is complete"

The shipboard host completed a preliminary analysis of the current observable atmosphere through the data collected by the optical detector and the planetary exploration equipment such as the optical spectrum analyzer, and gave an analysis report.

"The composition of the fugitive layer gas is as follows...... The particulate matter composition table is as follows...... "This is followed by the thermosphere, mesosphere, stratosphere and tropospheric data, and the last two atmospheres are too far away to give data error values that can only be used as references. The data on the report shows that the atmosphere is mainly composed of nitrogen, carbon dioxide, methane, oxygen, sulfur dioxide and other trace gases, and the spectral data of solid particulate matter shows that the level of planetary activity is relatively stable.

The data given by the temperature detector gave Su Zhao a lot of confidence; "At present, the average temperature of the remote sensing detection area is 263K, and the following is the temperature change curve...... The landfall conditions determined that a longer observation period is required. ”

After seeing the temperature data, Su Zhao decisively gave an order. "Main engine, generate orbit change mission, orbit change target, current planetary geostationary orbit."

"The mission has been generated and is being calculated in the current planetary synchronous orbit...... The orbit data calculation has been completed, and the orbit change scheme has been generated...... The fuel consumption optimization scheme is loaded. The estimated arrival time of the current plan is 47 hours"

"The main engine, based on the fuel consumption of the current scheme, takes 0.1% as the scale, generates a track change scheme in the range of 100% to 150%, fits the fuel consumption and time saving efficiency curve to give an optimal solution"

"The command has been accepted and the RG0144 formula combination is loading...... In the simulation of the orbit change scheme, the best result is obtained when the fuel consumption is 137.4% of the current scheme, and the estimated time of the orbit change scheme is 23 hours and 47 minutes, and the detailed curve has been generated."

Su Zhao looked at the calculation curve and nodded with satisfaction, and his rich mathematical skills were shown at this time. After all, he is a navigator, and all kinds of mathematical calculation formulas are still at his fingertips.

Mainly because Su Zhao drove Sirius for the first time to carry out a planetary orbit operation, many orbit calculation hosts are not very familiar with the scheme formula code, and they cannot directly use the formula set of the host to calculate the desired data.

"Hmph, if it was the previous Trident, I could have done the orbit calculation by squinting the code instructions"

"The main engine, adopt the optimization scheme, and confirm the orbit change command."

"The orbit change mission has been updated, and the estimated time to arrive at the current orbital perigee: 12 hours, 23 minutes, 14 seconds"

Originally, Sirius, as an extremely advanced Federation starship, had a common planetary landing mode of leaving warp space, following the regular navigation of the star's gravitational orbit to reach the vicinity of the Lagrangian equilibrium point where the planet needs to land, and directly cutting into the star's gravitational circle along the equilibrium orbit.

In this process, the speed of the spacecraft is adjusted between the second and third cosmic velocities of the target planet, and the orbital velocity is matched by acceleration or acceleration to the effective gravitational range of the planet. After that, it is to keep its own course and wait for the planet's landing permission, and after reaching the orbital perigee, slam on the brakes, no, slow down, and rely on the planet's centripetal gravity to approach the surface.

At the same time, a function of the supercavitation device of the warp engine is used to form a closed electromagnetic force field that wraps the ship, which repels the planetary magnetic field and plays the function of canceling gravity on the planet's surface. Combined with a deceleration propulsion, it can penetrate the atmosphere at a slow speed and fly relatively easily in the near-Earth atmosphere of the planet, without having to think about aerodynamics.

But it was very hard, Sirius first broke the warp engine, but fortunately it was in the star system when it got out of the low point, and the spacecraft still maintained a relatively high initial velocity, but in this way, it had to use a relatively primitive orbit change and orbit change to wriggle in the star system.

Most of the long flight time is spent in orbit waiting for the orbit change window. Every time he loses orbital speed and enters the inner orbit, to be honest, Su Zhao's heart is actually broken during this long orbit change flight period. Except for going to the orbit of the stars during his studies as a navigator, he has not suffered this crime since he was on the starship internship.

Now that the planet is in front of him, he still has to wait for the perigee and change the orbit again and again, Su Zhao is now irritated when he hears the word orbit.

If you don't wait for the past, you can just plunge into the star atmosphere and then step on the brakes and open the force field at full power, and you will be rich, not bad for fuel and electricity. No, after there is a fusion reactor, there is basically no electricity bill, it should be said that fusion raw materials.

It's just that the way of heaven is good for reincarnation, who does the sky bypass, although Su Zhao himself has always been more selective, no, it is thrift, but the retribution of their group of people has come to the head. Now every bit of the spaceship's resources are non-renewable, and it can only grit its teeth and endure these more than 20 hours. Wait for the spacecraft to approach the planet's synchronous orbit for better observation of planetary data.

"Mainframe, estimate the minimum fuel consumption for landing on the planet's surface from a geosynchronous orbit"

"Calculating the pre-stay coordinates of the synchronous orbiting spacecraft...... Planning the landing flight route...... Data is being calculated; Estimated consumption: 3.25% of conventional fuel, 1.31% of fusion raw materials" Su Zhao was a little distressed when he heard the data report of the host, because of the relatively high gravitational acceleration of this planet, although the fuel consumption ratio of the asymptotic deceleration action on the surface is similar to that of the usual landing in his hometown, but the fuel capacity of the Sirius is about 60% higher than that of the original Trident, that is, ......

"Blood loss, landing on a planet costs so much fuel, this is my life!"

Su Zhao looked at the existing resource data of the spaceship and started to think crookedly.

"There are so many antimatter, the closed magnetic field device is powered by the antimatter furnace at full power, and the full-power magnetic field can be better decelerated, and now antimatter is not used, it is better to use the full-power magnetic field deceleration handle."

"Fuel consumption of the landing scheme of the main engine, simulating the full operation of the magnetic field device"

"The scenario is being simulated; Fuel consumption: conventional fuel 1.16%, fusion feedstock 3.11, antimatter: 0.19%"

"The directive warns that in violation of CAS4454 safety regulations, the planetary magnetic field is fully engaged in the closed magnetic field. This operation may cause a large-scale disturbance of the planetary magnetic field, which will seriously affect the ecological environment of the planet's surface. ”

Warning or not, Su Zhao doesn't care, anyway, there is no one on the straw star, ah it's not an alien creature to sue himself, and he hasn't detected any scientific and technological satellites or anything after observing for so long. It's just that the exponentially increasing consumption of fusion raw materials has made me bored.

"Host, why has the consumption of fusion raw materials increased so much? Isn't it an antimatter furnace? ”

"To turn on the annihilation reaction of the antimatter furnace, it is necessary to meet the power requirements of the binding field deployment device and the heat dissipation system to operate at full power, so the consumption of fusion raw materials increases." Yes, this is another knowledge point that Su Zhao doesn't know. He quickly checked the information and found the operating instructions of the antimatter furnace, trying to figure out how the antimatter reactor worked.

The principle is very simple, that is, the positive and antimatter particles collide with the annihilation reaction, releasing a large number of high-energy form photons.

Here is a small point of knowledge, photons, also called light quanta, is a kind of energy structure unit that produces pure energy, not a material particle, which only has relativistic mass and is defined as 0 at rest in quantum mechanics. Rather, it is precisely because of the pure energy properties of photons that it moves at a constant speed of light and is not bound by gravity. The process of photons being absorbed or released by the particles of basic matter is the transfer of energy, and the process of photon energy transfer and transfer is heat conduction at the macro level, and the definition of heat is the energy value of photon transfer.

The specific microscopic field research is already very advanced in federal science, and Su Zhao can't understand the detailed information.

The antimatter furnace uses the reaction cavity made of total reflective matter and the refractive structure of multi-layer glassy matter inside, and then calculates the structure arrangement and reflection orbit by using the principle of light path, so as to realize the route deflection of high-energy photons, that is, the directional transfer function of energy.

Due to the difference between the theoretical state and the actual state of the annihilation reaction, theoretically the light reflectance of the total reflector and the transmittance of the glassy substance are both 1, but it is a limit value that is impossible to reach in practice, and it will still absorb energy due to the dissolution of photons and internal constituent particles, resulting in heating. This requires a complex heat dissipation system with helium-8 superfluid as the heat conduction medium for structural heat dissipation.

In the reaction process, because of the accuracy of the feeding, the impacted charged positive matter particles will gain kinetic energy to escape, so the internal magnetic confinement force field is also required to deflect the trajectory.

Therefore, the inside of a single reaction chamber should ensure that the material particles have been deflected and discharged when feeding, so the reaction is carried out intermittently, which will lead to the instability of the output power, which requires a group of reactors to have more than two reaction chambers to operate alternately to ensure the continuous and stable output of power.

Considering that the efficiency ratio has a power-volume optimal curve, coupled with the limitations of various macroscopic conditions such as material science limit, reflection limit, thermal conductivity limit, light transmission limit, etc., as well as the technical problems of antimatter delivery, Federated Technology has manufactured today's standard reaction unit after years of technical exploration and practice, and has also optimized a number of mature unit solutions that have been tested in practice for a long time.

The Sirius is equipped with a federal 7th generation S-class integrated antimatter reactor unit, consisting of 3 standard units. The S-class represents a small starship that is specially available for small starships, and its size, power and price are extremely suitable for warp sailing of small starships below 200 meters.

It is one of the best-selling federal classics.

……

After reading the information, although Su Zhao was dizzy and dizzy by the clouds of information, he still roughly understood the reason for the increase in energy consumption with his profound literary skills of insisting on reading novels for many years.

"It turns out that the antimatter unit needs a huge instantaneous power when it starts cold, and the fusion unit needs to enter a state of high power at this time, thus consuming more fuel; After entering normal operation, the unit can self-generate electricity to maintain operation, so it is...... But I still have to complain about the person who wrote the information.,How to write it's not human words.,I'm a mechanical genius who can't understand it.,If there's a scoring system, I'll have to give a bad review! ”

"Bad review! ~" Su Zhao complained and chose to go to the nutrient solution to intubate and relax.

He inhaled the carbon dioxide he had injected from the gas supply pipe, and the sparkling water with the glucose solution floated on the luxurious bed in the captain's room. Although there are still 98% of the high-energy batteries in the body, I still choose to plug in the power supply cable and think about life.

……

"1h countdown to the current orbital perigee, please ask the commander to determine the orbit change plan."

"I'll just say if I forgot something, host, sure!"

"I don't want to hear the word derailment anymore!"

Finally, there is a condescending and obscure sentence that begins with I love you, and the whole captain's room is filled with a cheerful atmosphere.
