Chapter 1010: 16. Fortress vs. Fortress (33)

Roland did not know what his friends said about him, nor did he know that he was a childhood friend. At this moment, he is devoting himself to dealing with the "technical problems" pointed out by his friends.
Bundled rockets are placed in any world where there is no computer, aerodynamics, basic theoretical level of aircraft engineering, the overall structure of the aircraft is designed for strength analysis, test capabilities, etc... Rockets are even more dangerous-suicide rockets can still bring a little damage to the enemy, and the results of the bundled rockets are all their own...
In peacetime, whoever proposed the idea of ​​"tied the missile to the floating ship, let's go to heaven together", Roland had already passed away. Even in wartime, the guy who put forward this kind of plan will be invited by the gendarmerie to drink alternative coffee because of the suspect of a major spy. What makes people cry and laugh today is that this plan was actually proposed and implemented by Roland himself.
Just because this is the only opportunity.
How to break through layers of protection and take down the generals of the enemy generals and even the king? Is it sending a large army to kill a path? Is it a mobile fortress that is chanted as never falling? Can the 200,000 army do it? Can 500,000 do it? Can 1 million do it?
The conclusion is that it is impossible.
In front of strategic weapons, the number is meaningless. In the process of assembling troops, as the troops advance, during the process of replenishing supplies for production, storage, and transportation, the super cannon will be launched, and any group targets that gather together will become various strategic-level attacks. Victim. As long as the speed at which people can gather forces cannot exceed the firing interval of that super cannon, everything is meaningless.
As long as the opponent presses the launch button, the battle is over.
There is only one chance. In just a few minutes of tens of thousands of sacrifices, how can I cross all the enemy's defenses and take the Iselon fortress within the time of burning a cigarette?
Only rockets or missiles.
However, even a rocket or missile that transcends the speed of sound, whether it can correctly hit the target or break through the airspace of the fort, is also a problem that can not be reassured.
The results were discussed and discussed. The final solution to the compromise was to install the six A-4 rockets seized on the enhanced Endeavour. By reducing the load, the output power of the parallel rocket engines can meet the requirements of high parabolic trajectory (here, let me mention a little, high parabolic trajectory has strict requirements on the thrust of the missile. Taking "Mars 15" as an example, its range is only 960 Kilometers, but the shooting height reaches 4500 kilometers. According to the principle of high ballistic flight, the standard range can reach 12000 kilometers. The higher the shooting height, the closer the range. If you want to increase the range without changing the shooting height, you can only increase it. Engine thrust). According to theoretical calculations, six A-4 rockets using metal hydrogen as fuel can indeed be sent to the top of the Iselin fort after using the "weight loss" of the floating technique. But the premise is that the six rockets with warheads removed can be pushed in parallel in parallel, without making any mistakes during the entire launch process.
As long as there is a little error, or there is an error in the ignition timing, or the output power is inconsistent, or there is a surge in the air, or a certain screw is loose, or the fuel line there is faulty, everyone waits to become a firework.
It is said that this kind of technical problem requires at least a large-scale professional team to tackle the problem for more than ten years before a breakthrough may be made, but in the whole plan, this is the easiest to solve. The reason is that during the analysis of the MDS "Unicorn" maintenance and repair materials, it was found that there was a draft plan with a technical description-"Full-armed Unicorn". The "long-distance mobile component" mentioned in it is to install a rocket on the back of the "unicorn" to make it stand-alone long-distance high-speed mobile capability. According to the instructions, although the entire draft plan was stalled and not implemented, the "unicorn" has already installed the relevant control programs. As long as it is connected to the rocket control port, it can fully realize the parallel launch operation of multiple rockets.
The A-4 rocket naturally adopts the technical specifications of Alfheim, and is fully compatible with the connection port of the unicorn. After several simulation starts, after confirming that the start signal and the connection are normal, the unicorn is loaded into the Endeavour. The control unit, the transformation of the fixed rocket in the hull of the Endeavour began. After more than a dozen days of sleepless days and nights, a group of technicians finally rushed to complete the modification work before the final battle day.
The propulsion of 6 metal hydrogen rockets is enough to push the floating Endeavour to a height of 20,000 meters, only because of the fear that the hull structure and the crew’s body cannot bear, plus the excessive height will accumulate during the descent process Too much kinetic energy causes problems with handling, so the ultimate ceiling is limited to 14,800 meters.
But even with such a compromise value, for the crew of Endeavour, it is still a dangerous journey, and all the mistakes can be destroyed.
Based on the ground, the standard atmospheric pressure is 101.2 kPa, and the oxygen content is 299.3 grams per cubic meter. As the terrain increases, the air pressure gradually decreases, and the oxygen content in the alveolar gas, arterial blood, and tissue also decreases accordingly. Symptoms such as tinnitus, vomiting, headache, and shortness of breath may occur. In severe cases, clinical symptoms such as cramps and fainting may also occur. This is altitude sickness. Generally speaking, entering an area above 4000 meters above sea level will cause an alpine response. Depending on the speed of entering the plateau area, physical fitness and other conditions, the probability of morbidity will also change. The incidence of acute altitude sickness is 83.5%. However, the morbidity was only 52.7% when it was adapted from 2260 meters to 4200 meters within 7-15 days by ladder.
So what happens when you rise to 14,800 meters in a few minutes? The answer is that without protective measures, the incidence of altitude sickness is 100%, and it will be accompanied by various complications. At an altitude of more than 10,000 meters, the oxygen content is only 20.93% on the ground, and the air pressure is only about 30 kPa. Not only will it suffocate, the lungs will also rupture on the spot, and the scattered blood flowers will instantly freeze in the gusty wind of minus 30 degrees.
What Endeavour is entering is such a hell-like life exclusion zone.
If not relying on Fafna and Dendrobium to continue the operation of isolating the low temperature and the air pressure, the ship would have been corpses everywhere.
Using unicorns to control rocket flight and ship attitude adjustment, and using Dendrobium to open the barrier to maintain the hull-this head-to-head solution actually successfully sent the Endeavour to a height of more than 10,000 meters. No one fell.
"Rocket thruster separated."
Along with the instruction, the huge streamlined rocket parted from the end of the Endeavour, and the burning body was scattered in four directions. The hull of the Endeavour, which was in the center, shone in the sun and became the cross core of the four flash points.
This situation is like a blooming flower, with a holy cross pattern painted in the sky.
Endeavour, which lost its propulsion device, still climbed a certain distance under inertia. When climbing to the highest point of 14,800 meters, the hull took a slight pause and the bow began to sink to the ground.
The second ghost door, which was more difficult and dangerous than climbing, opened the door to Roland.
