Looking at her questioning and questioning eyes, Roland thought that she was quite cute when she was blaming someone … She rarely called him brother when she was in a good mood. She would only call him brother in front of outsiders or when she was annoyed, which made people want to tease her.
"Ahem, no, now is not the time to think about this …" He coughed lightly and pulled his thoughts back on track. "The plane has not been finalized yet, so every part has to be made by Anna and Soroya. Now that the war at the front is imminent, you should know better than most people how much work they have to do. Although I've completed the blueprint a long time ago, I can't turn it into reality by myself. "
With the extension of the railway, the interval between the "Seagull" and the front line had changed from one or two days to three or four days. It was not that Tilly and Vendy wanted to slack off, but a large amount of war preparation work could not be completed in a day, so there was no other way but to extend the duration of the stay.
As the transport, Tilly naturally knew how hard it was for everyone. Many witches fell asleep on the seats as soon as they boarded the plane. For this reason, the "Seagull" had even replaced the cushions and backrests with more comfortable ones. Moreover, defeating the demons and taking back the Fertile Plains was the most important goal at the moment. As soon as this was mentioned, her imposing manner suddenly decreased, and her body that was propped up on the desk shrank back. "I also want to start the test flight early so that the Air Knight can be put to use …"
"Don't worry, in fact, the plane's main body is basically completed, only some auxiliary parts have not been installed, so you just need to be patient —"
"Wait," Tilly interrupted. "The main body is completed, so … it can fly without those parts, right?"
"Uh," Roland only then realized that he had let the cat out of the bag. At this time, Princess Tilly was no longer the amateur who knew nothing about planes, so it was not easy to fool her. "… It's not that it can't, but it is, after all, fundamentally different from the 'Seagull'. If there is a problem, Vendy can't help fix it, and if there is a mistake …"
At this point, he gradually closed his mouth.
Because Tilly's sparkling eyes had explained everything.
He really couldn't resist such a gaze.
Nightingale chuckled softly behind him. Recently, she seemed to be very happy to see him at a loss for words.
After staring at each other for a long time, Roland let out a long sigh. "Alright, I'll inform the people at the airport to get ready."
"That's more like it." Tilly's raised eyebrows finally lowered, and the corners of her mouth revealed an irrepressible joy.
He picked up the phone. "But remember, if there is an accident during the test flight, or if you lose control, you must abandon the plane immediately. Do you understand?"
"Of course, because planes can be rebuilt, but pilots like me are precious," Tilly crossed her arms and said proudly, "That's what you think, right?"
…
Neverwinter Airport.
In the beginning, it was just a simple piece of concrete with nothing but two runways. But now, it was a real flying training ground and the prototype of the Air Force Academy.
In the enclosed flight test field, a shiny silver plane was pushed out from the hangar by workers and placed at the end of the runway.
Tilly took a deep breath and said, "That's … specially made for me …"
"Yes." Roland nodded. "The 'Unicorn' is powered by a five-cylinder star-shaped piston engine. The main power is provided by a five-cylinder star-shaped piston engine. In theory, the plane can reach a speed of more than 150 kilometers per hour. Even the fastest Devilbeast can't catch up with it. "
As the first human-made autonomous aircraft in this era, the 'Unicorn' looked very different from the 'Seagull' glider. The most obvious difference was its huge head. In order to fit the engine, the nose of the plane had to abandon its aerodynamic streamline appearance and be shaped like an iron barrel, which looked like it had been shaved flat.
Second was the two-blade propeller in front of the nose, which was also missing from the 'Seagull'. Since it was the first practical piston engine, even with a lot of reference materials, the final product was quite conservative. Since the power output was not high, the two-blade propeller could meet the requirements.
Lastly was the fuselage. Because the 'Unicorn' was essentially a fighter, it was less than nine meters long, almost half the length of the 'Seagull'. The fuselage also did not need to carry passengers, so it looked quite small. However, the interior of the fuselage was much more complicated. In addition to the control system, there were also fuel tanks, fuel pipes, and other power components. There was also space for a second seat and a firepower system.
"Unicorn … You can come up with some good names sometimes." Tilly hurried to the biplane and quickly noticed the abnormality in the cockpit. "Were the missing auxiliary parts originally installed here?"
There were still two holes where the instrument panel should have been. Even though she had never seen the actual thing, she could guess that it was not completed yet.
"Yes." Roland nodded. "These parts are mainly used to display speed and altitude, which are the two most important parameters in flight. In the past, Vendy controlled the plane's attitude, so we didn't need to know these. But if we want to fly with our own strength, we must always pay attention to the changes in these two parameters … "
"Don't worry. I may not know how to build a plane, but when it comes to piloting, I'm definitely the best in Graycastle." She climbed onto the plane confidently and sat in the pilot's seat.
In theory, the 'Unicorn' only had one more throttle valve than the 'Seagull', and the rest of the control levers were in the same position. Before this, Tilly had practiced on the simulator many times, so there should not be any mistakes. However, this was, after all, a brand new plane. Its weight, agility, and speed were very different from the 'Seagull'. The mechanical system had not been fully tested, so it would not be surprising if there were any problems.
This was also the reason why Roland was worried. If the plane crashed as soon as it took off, even if Tilly had extraordinary piloting skills, she might not feel anything. At first, he had wanted to build a few prototypes so that she could familiarize herself with the new body while crashing.
But at this point, it was impossible for her to change her mind.
"Your Majesty, everything is ready," the hangar supervisor reported.
"Let's begin." Roland turned around and left the runway.
"Yes!"
As the order was given, two workers inserted a hand crank into the engine's starter and started to turn it hard.
"I'm testing the latest human weapon, but this scene is just like the hand-guided tractor when I was a child …" Roland could not help but curse in his mind. When the time comes, he must get the battery and auxiliary motor out no matter what.
"Bang, bang, bang —" When the piston gradually accelerated under the influence of external force, a worker closed the pressure relief valve, and the oil in the cylinder was instantly ignited. The engine erupted with a few loud explosions, and at the same time, black smoke rose. Very soon, the sounds of explosions became one, and finally turned into a deafening roar.
