Six Hundred and Twenty First Not so Simple
What Qiu Tianning said was simple, and the first brother answered it happily, but how could it be so easy in practice?
Not to mention anything else, the engine is hung under the short wings, which means it is exposed to the outside of the battleship, instead of being protected by thick armor inside the battleship. In this way, the engine becomes the most obvious and prominent bullet point of the battleship, and its safety Sex is a very tricky subject. update the fastest
In order to solve this problem, the design institute came up with several different schemes for demonstration, but the results were not satisfactory.
One is the wing-body fusion scheme, that is, cover the short wings with armor, integrate the engine into the hull, open the armor on the engine through the hydraulic device in the wing body, rotate the engine 180 degrees, and then close the armor again to change the engine jet. direction purpose.
However, this kind of deformed structure is complex and fragile, and it is no safer than the short-wing scheme when used on a battleship. On the contrary, it will greatly increase the construction cost and maintenance cost, which is not cost-effective no matter how you look at it.
The second solution is to use a large vector nozzle on the battleship. Through reasonable design, the vector nozzle placed on the stern protrudes out of the outer edge of the stern to achieve the purpose of spraying forward.
The warships using this scheme do not need to change the design of the warship, and the existing warship can directly replace the engine to complete the modification.
But this plan is actually more unreliable than the first one.
The existing warships use electromagnetic engines, which rely on electromagnetic waves to generate thrust. If vector nozzles are used on the electromagnetic engines, the electromagnetic waves will hit the side walls of the vector nozzles, and the little bit of propulsion will be absorbed by the structure of the engine itself. directly offset.
There is no problem with the applied jet engine, but even if the fuel consumption is not considered, the flame sprayed from the combustion chamber must first hit the outer wall of the vector sprayer, and then spray out of the engine in a circle of 180 degrees and a half outside.
This requires that the material used to make the vector nozzle must have excellent strength under high temperature conditions, otherwise it will inevitably fail under the impact of the flame flow.
On the earth, this problem is easy to solve. After all, where the ambient temperature of the earth is, designers only need to consider the strength of materials at room temperature and high temperature.
However, space battleships have been sailing in the universe for a long time, and the materials used on the battleship must consider the impact of extreme low temperature, and the engine is no exception. This greatly reduces the choice of engine materials, and makes designers scratch their heads.
It is not impossible to use high-temperature materials to manufacture warship engines, but the ambient temperature in the universe is too low. If the nozzle material becomes brittle and hard due to the low temperature after the engine cools down, it may break if a little external force is applied. Who can not worry about such an engine?
Finally, the twin-engine solution,
That is, a set of propulsion equipment is installed at the head and tail of the battleship, the rear one is used for advancing, and the front one is used for braking, which is also called a balance scheme by the designers.
The balance plan can only be regarded as a compromise method. It seems to take into account both defense and maneuverability, but the front engine will occupy a lot of space on the bow, crowding out the installation position of weapons and equipment, and greatly weakening the firepower of the battleship. Isn't this killing me?
Just when the design institute racked its brains but couldn't come up with a practical solution, the military actually issued a new design task, requiring the design institute to design the space carrier as soon as possible, and must come up with three displacements of large, medium and small. design plan.
The dean of the design institute almost went all the way to Beidu to have a table with Qiu Tianning.
What are you kidding? With the propulsion power of the existing engines, a space warship with a displacement of 5,000 tons is already the limit. It is not that a larger and heavier warship cannot be designed, but that it cannot fly at all after being designed. What is the use of such a warship even if it is manufactured? use?
However, the design institute soon knew that the military was not joking, but was serious, because the military sent all the "Orion Project" materials obtained from the Americans to the design institute, requiring the design institute to understand the information as quickly as possible. Design a practical nuclear powered engine.
The design institute lost its eyeballs all over the place again, and directly launched the nuclear power engine. Is this his grandma's Great Leap Forward?
But after thoroughly understanding the information of the Orion project, it was discovered that the nuclear power engine was not impossible, and the related design work was immediately carried out in full swing.
Although the Orion project with a big brain hole died halfway, there is no problem with its design principle. It is only a matter of time before a practical nuclear power engine is designed. As a result, the design plan of the nuclear power engine has not yet been released, but the design drawings of the space carrier are not. First out of the design institute.
According to the requirements of the military, the design institute provided three large, medium and small design drawings of the space carrier.
The small space carrier has a displacement of about 30,000 tons, can carry about 30 space fighters, and is equipped with naval guns, missiles and other naval weapons. It is flexible and can perform various low-intensity combat missions. Form a mixed fleet to provide fire cover for the fleet.
However, limited by its size, this type of space carrier has weak self-sufficiency, is more dependent on logistics, and lacks long-distance navigation capabilities. It must have supply ships to follow or back against the base during combat, and the cost performance is not very high.
By reducing the number of aircraft, other capabilities can be improved, but the space carrier originally relies on carrier-based aircraft to fight, and reducing the number of aircraft will only make this type of warship less cost-effective.
The medium-sized space carrier has a displacement of about 70,000 tons. It is also equipped with a large number of naval guns and missiles. It can carry about 70 carrier-based aircraft. It has the highest comprehensive performance and is suitable as a powerful combat unit in the fleet.
The large space carrier has a displacement of 120,000 tons, carries 120 aircraft, and is equipped with many powerful weapons such as laser cannons, near-anti-aircraft guns, and missiles. It is a combination of space carrier and large-scale battleship.
Although this kind of warship has the disadvantages of long construction period and high cost per ship, it has the highest cost ratio and has extremely strong offensive capabilities. It is the core force of the space fleet.
Although the design plan has been taken out, which design to adopt will not be announced until the nuclear power engine is designed. During this period, the Design Institute has carried out a series of optimization and revisions to the drawings.
For example, based on the experience of the expeditionary fleet, the lifeboat was canceled and replaced with a rescue cabin.
The rescue chamber has a built-in plutonium battery, which provides heat and electricity. After the crew enters the rescue chamber, the rescue chamber will automatically inject hibernation for the crew. The stored oxygen and water can ensure the survival of the crew for five to seven years. precious time.
Moreover, this kind of hibernation cabin has its own navigation system, which is launched like a missile when it leaves the ship, and automatically flies to the earth or a designated location under the control of the navigation system to ensure the safety of the crew's life to the greatest extent.
All in all, improve combat effectiveness while improving survivability, and optimize the performance of warships as much as possible. (To be continued..)
