And not only can the furnace be controlled, but the flame temperature output is also sufficient. At this time,
Only airships have the basic ability to reach the sky!
But this alone is not enough. Even just talking about God is not enough.
The stove fire is big enough, but how can the air bag withstand it?
That’s something completely unspeakable!
And even if the airbag can withstand it, the airship can really reach the sky.
After getting into the sky, how to control it? How to control the flight speed and the entire vector?
This comes to the really complicated and difficult part.
Li Sheng needs to research a propeller for flying!
With this thing, the airship can truly fly freely, unlike the hot air balloon used for reconnaissance before, which can only observe the climate and wind direction, roughly guess the liftoff, and then basically rely on luck to land.
Although the hot air balloon was able to land smoothly, it was indeed a truly random landing - fortunately, Li Sheng was highly skilled and experienced, and was finally able to reliably control the rising and falling speed of the hot air balloon.
However, randomness is random, it is just that military reconnaissance does not require such precise landing.
Of course, it is possible to land directly into the enemy's old camp, but the probability of this is relatively small. After all, the airship will not be used casually and will definitely be considered for recovery. Secondly, even if it is discovered by the enemy,
Generally speaking, it doesn't matter.
Because among the bows and arrows of this era, the most powerful one is the Song-style divine arm bow made by Li Sheng himself. Its longest range is more than 300 steps - not to mention the craftsmen who can shoot 300 steps away. When shooting upwards, the wind resistance and other factors are considered.
The problem is, it would be a blessing to have a height of dozens of steps, even if it can shoot from 300 steps.
This hot air balloon in the sky naturally has a passive skill similar to Sun Fist. When you look up at the hot air balloon, your eyes will have to bear the sun's heat. Although there are many literary and artistic works in later generations that have plots of heroes shooting vultures.
, but in fact this is a very difficult action to do - not even difficult to complete.
Not to mention that although hot air balloons are not as fast as birds, the flight of birds is different from that of butterflies and the like. Their flight trajectories are very easy to control, and they can be shot down with hard work.
Although the hot air balloon moves slowly, its movement is basically random - you can even remove the word "basic".
Therefore, although such a thing in the sky cannot be controlled to land randomly, it can actually be said that it is not that easy to cause problems, and it is still a good thing.
Very good stuff.
——However, this is the part that Li Sheng couldn't help but secretly complain about. From Li Sheng's perspective, the Tang Dynasty has not yet developed a more useful airship. It is obvious that this old-fashioned primitive hot air balloon is too easy to use.
If you spoil the brains of these unscrupulous people in ancient costumes and make them unable to think about progress, or to control the direction of things that cannot be controlled, wouldn't it be of greater use?
But complaints are complaints. Since no one is doing it, then of course it depends on your own performance.
But what makes Li Sheng happy is that he is a man in science and engineering, and he has done well in key studies. Although he is not top-notch or even famous, he has mastered the basic subjects, and the old-fashioned propeller engine structure is actually good for Li Sheng.
Not that complicated.
Of course, the fact that the engine is not complex does not mean that the entire project is not complex. Just as there are not so many awesome black technologies on mobile phones in later generations, most parts are still ordinary level technologies, but how to turn these ordinary technologies into beautiful and smooth ones?
The mobile phone will test your skills.
The same goes for this airship. The stove can solve it, and the propeller engine can also solve it, but when these things are added up.
It can be imagined that the "basket" of this airship, that is, the loading space, will definitely be occupied a lot, and the key is that this occupation is not a concentrated part, just like the battery in a mobile phone, the remaining
The parts can be arranged in any way, but they are occupied in a distributed manner.
After all, both the stove and the flame must be evenly distributed!
For an airship to be able to accurately fly in a predetermined direction, it will undoubtedly require the use of more than one propeller - only one propeller can at most ensure the rapid travel of the airship, but not the problem of steering.
As a result, the space in the airship's "basket" will naturally become very unsuitable for carrying passengers——
but.
At this time, it is natural to return to the original starting point. All tests are not a problem for real professionals!
For Li Sheng, the firepower and wind power of the stove and propeller must be balanced on the airship, and they do not need to be spread out so flatly, because the plan to build the airship is to carry passengers, so of course it must be made in a long strip
——Since it is to be made into a long strip, of course the furnace and propellers do not need to be placed everywhere, as long as there is one side at the beginning and the end.
There are a set of furnaces and propellers at each end of the head and tail, and then supplemented by certain mechanical control devices, the space in the middle is naturally freed up as a whole space. Of course, this is ancient times after all, and the conditions are extremely limited in the first place. Even if Li
Sheng put all his efforts into the design, and the space in between was bound to be crowded.
This part is not a big problem for Li Sheng - just like the antennas of the sixth and seventh generations of Apple were eventually made into key decorations, as long as they follow certain rules, Li Sheng can clearly see
, this shortcoming will not only not become a problem in the future, but will also become a key symbol of airship travel, and even become a "luxury point" like Apple!
This means that although this airship has flaws, the thing itself is the crystallization of high-tech. At the same time, as long as the interior decoration and service-type things are arranged in place and are luxurious and good enough, then this kind of crowding, hehe, not only will it not
It will become a shortcoming, and it will also become a material for the airship passengers to brag to others about Versailles literature in the future!
Only when you reach this point can you truly call it business success!
But for such a wonderful plan, first Li Sheng still needs to develop a more efficient and easy-to-use stove and a propeller engine.
Only with these two cores can the airship be considered usable.
In addition to these two parts, with a propeller engine, does it also need a control system?
How to make this control system is obviously a difficult problem - to achieve stable and accurate flight and steering, it is necessary to control the propellers at both ends at the same time, and because the furnace that generates hot air needs to control the lift, when lifting, it cannot always be done at one end.
One is high and one is low, which obviously requires synchronous control, which is very difficult to do.
Fortunately, Li Sheng knew a technology called "hydraulic pressure".
