After careful consideration, Lin decided not to explain what "braking" meant. Instead, Totokani sat in the driver's seat and actually operated the takeoff airship.
Although the layout of the pilot's seat of the renovated airship is said to be imitated in the shape of the earth, it is actually much simpler than the real thing. Because someone has only experienced flight operations from certain flight simulation games, and the cockpit layout can only be seen from online photos and movie scenes. Therefore, the restoration work only uses the experience of the earth as a reference, and basically designs based on actual needs.
To put it simply, apart from some switches, there are only rudders; the first throttle valve responsible for the floating magic circle, which controls the altitude; and the second throttle valve responsible for the engine throttle, which controls the speed. The next step is to switch between the two modes of navigation map and enemy detection radar.
Because unlike the Earth, there is global climate data support, as well as licensing restrictions on waterways and navigation rights. Therefore, in navigation mode, after specifying the forward city, the map will only guide the direction of the shortest distance in a straight line. The remaining detailed controls, including related parameter settings and coordinated operations of multiple devices, are actually in the control program written by Fen.
To put it simply, the control of the airship is simplified to a fool mode. All you have to do is use the X-box controller to control the submarine like the old Americans.
Although the goblin's nerve lines are not necessarily connected to the correct location, their IQ is still online. There is certainly no reason why Totokani can't learn the airship control that has been simplified to this extent. Even others are eager to give it a try.
After a brief teaching, Lin said to the goblin: "Because this is your first time controlling the Sid, I suggest you not to do too fancy flying, just fly smoothly. The most important thing now is to get used to this kind of flying." Control methods, and instrument operation.”
Totokani pointed at each device on the driver's seat and repeated the name and purpose. After confirming that the basic knowledge he learned from the operation manual was indistinguishable from reality, he took hold of the fixed rudder and unfastened it. Really master this airship. Totokani asked a question: "But none of these functions seem to be related to landing. Do they need to be operated elsewhere?"
Although the Sid has Fen's integrated program, all controls and status instruments can be operated from the driver's seat. However, the operation of individual equipment can still be completed elsewhere. That's why the goblins asked this question.
But the answer was not what the goblin had guessed. Lin smiled and patted Totokani's thin shoulder, and said: "As expected of someone who has flown an airship, you can think of these things. As for the landing function, I have to start thinking about it now, so I will First, please sit in the driver's seat and take over the airship. That's it, drive calmly."
"Alas, alas~!" The goblin who didn't understand at first just responded casually, but after he figured it out, he shouted in a fuss, followed by a crackling goblin greeting. But just by looking at his expression, Lin was too lazy to understand what the goblin wanted to express. It is more important to figure out how to brake and how to land first.
A common scene in science fiction movies, the spacecraft has the maneuverability of a helicopter and can take off and land vertically on any terrain. This is something the Sid cannot do. Because the buoyancy of the Sid is buoyancy, and the propulsion is propulsion, the two are not integrated together.
Secondly, as the engine of the propulsion mechanism, the propeller blades are directly connected to the engine crankshaft without passing through the gearbox. Therefore, the size of the propulsion force depends entirely on the throttle controlled by the throttle valve, which determines the engine speed. It can neither shift gears nor reverse.
Although it can match the airship's flight maneuvers, the engine has an adjustment range of fifteen degrees up and down, for a total of thirty degrees. But after all, it is impossible to change the propeller vertically upward like the Osprey tilt-rotor aircraft to achieve maneuvering like a helicopter. What's more, the engine is placed at the tail of the aircraft, so it can rotate 90 degrees upwards. It is also light in the front and heavy in the rear, making it unable to fly normally.
On Earth, the same propeller aircraft needs to slow down in the air. In addition to slowing down the blade speed, it also needs to open the flaps to increase wind resistance. In the end, you have to land at the airport and rely on the friction between the tires and the ground to stop the inertial force of progress. This approach also doesn't work for the Sid, because the Sid doesn't have tires.
I originally thought that relying on the vertical take-off and landing ability of the floating magic circle would be enough, so someone didn't consider the issue of deceleration at all. But after it really went to heaven, deceleration became a difficulty that had to be faced, and it could not be let go as lightly as originally expected.
It can only be said that no matter how thoughtful you are on the ground, you will always find fatal omissions once you go up to heaven. It’s no wonder that developing aircraft on Earth requires countless test flights.
Although there are wings on both sides of the Sid, they are more like rudders that control the attitude of the airship. The effect of using the tilt angle to increase wind resistance is limited.
By stopping the engine so that the propeller blades no longer provide thrust, the airship will naturally not be able to maintain its current full speed flight. But waiting for the airship's speed to return to zero is unlikely to happen. Because even without power, the aircraft can still ride on the airflow and maintain a certain speed just by gliding. Therefore, it is impossible to expect that the airship will naturally remain stationary in the air.
Then, you have to think about ways to increase wind resistance from other directions.
Walking to the workbench that had not yet been removed, Lin took out the coffin and placed it on it, and started a new round of simulation calculations. At this time, other people who were belatedly realized the problem they were facing now, under the shouts of Polly's translator Totokani. Everyone didn't complain, but put forward their own opinions and methods. No. 6
In view of the multiple ideas and approaches, Lin still listened to their opinions very carefully. After all, one's own thinking logic is easily restricted in the nest of the earth. Maybe the magic of the lost land can find different ways to achieve the goal. But the result was a pity, none of them were useful.
Slow down, land, and most importantly maintain the integrity of the Sid. As long as the structure of the airship is not damaged by any movement, there will be no major problems for the people inside.
However, according to the method proposed by others, after simulation, the proportion of the airship being smashed into mud at the moment of landing is as high as 90%, half of the time the airship will disintegrate in the air, and the remaining half of the time the airship will be seriously damaged. At least half of the people inside would be killed or injured.
Almost no deceleration method proposed by anyone can pass the test, which is also limited by the existing conditions of the Sid. The only thing that is more promising is to shut down the engine and find a way to make the airship turn around 180 degrees and fly with the tail of the ship facing forward.
However, the airship's exterior design takes into account the wind resistance in the up, down, left, and right fronts, but does not consider the situation directly behind it. If it is flying with the tail facing forward, the low-speed situation is fine. In a medium-high-speed environment, structural instability can easily occur, leading to the risk of disintegration. In other words, if you want to fly in this way, you still have to find a way to slow down to below a certain speed.
The king who once soared in the sky could not offer any useful suggestions. The most important thing is that Augustus easily ignores the structure of the airship and proposes some methods that can only be achieved with the body of a giant dragon.
But to be honest, when this old dragon opens his mouth, it feels like he just wants to join in the fun, rather than really wanting to propose any solutions. Nonetheless, Augustus's idea of imitating biological flight may serve as an inspiration to someone. And when everyone was at a loss and came up with some bad ideas, they did simulation calculations on their own.
Seeing that the calculation result had a success rate of more than 70%, Lin was not going to continue thinking about other methods. The destination city of Abadan is almost reached, unless we have to waste time and fuel by hovering above. Otherwise, if you want to do something, you should take action now.
After making up his mind, Lin began to assign tasks to everyone. The first priority is to find a way to secure all the moving things in the airship. The second is the seat belt, which does not consider comfort, but only requires that the person can be firmly tied to the seat.
Although during the repair of the airship, some ropes were made from bark. When I left, these ropes were retained, but the number was still far from enough. So under Lin's instructions, the complete snow wolf skins were torn into strips, knotted and connected into long strips, and used as ropes.
Such behavior was an outright waste in the eyes of the knowledgeable Uzov Gantia, but he did not dare to say anything more. Even when the magician gave clear instructions, no one in the group raised any objections, but obeyed the instructions obediently.
For the two apprentices and the four silver-bearded dwarves, they had long been accustomed not to question someone. Anyway, when there is a need to explain, that person will naturally explain it to everyone. And when he doesn't want to talk, even if he asks, he will only get some more confusing answers. After all, the knowledge of both parties is not on the same level.
As a former Demon King, the Lich would not question anything. Because that man rarely assigns work to her, but whenever she is asked to do it, it is the kind of troublesome thing that others can't do. It is impossible for her to do ordinary heavy work.
The black dragon Augustus also belongs to this level. Lin didn't want to offend this humanized dragon, nor did he think that asking a crippled old man to help with things would be a blessing if he could really help and not hold him back.
The two goblins had long since succumbed to the magician's power. Ever since someone had compiled detailed goblin anatomy from his past experience of killing uncivilized goblins and introduced them to Totokani and Polly one by one, their legs did not tremble when they saw this man again. , which is already commendable for courage.
Maier didn't want to offend the magician any more, so she would flatter him if he could. It's no problem to devote yourself to sleeping, let alone some simple tasks. Uzov Gantia, on the other hand, does not understand this magician's brain circuit no matter what. If you can't even raise a question, what else can you do but just obey.
Therefore, the airship cabin was quickly handled properly according to someone's request. Everyone returned to their seats one after another, and after fixing themselves firmly, Lin and Totokani took over the driver's seat.
When someone took the rudder again, there were only about twenty minutes left to Abadan. Pull the second throttle valve back to the bottom and say: "Stop both vehicles and enter inertial flight. Start descending." At the same time, pull the first throttle valve back to the neutral position.
The engine is shut down to maintain idling, not to stall. This is to avoid the need for engine power when an emergency occurs. If the engine is turned off and started only temporarily, it is easy for something to go wrong under stress.
The Sid is currently at an altitude of 23,000 meters and traveling at a speed of 380 kilometers per hour. Both height and speed are decreasing.
