Sky Dragon Rider

Compared with turbofan jet engines running on aviation kerosene, crystal energy jet engines actually operate more efficiently and have lower wear rates.

The oil used in Jingneng jet engine is only a kind of medium. The project team chose a light natural vegetable oil with good low-temperature fluidity as the fuel base, and treated it with purification, hydrogenation thickening and oily blending. Through the catalytic medium The pipeline is poured into the turbofan combustion chamber, and the atomization efficiency and calorific value are increased by the wind and fire magic force fields.

Before the completely combusted flame leaves the tail nozzle, the hot air has been converted into high-speed and high-pressure air by the turbine and the local wind magic array, so as to obtain a very high-efficiency thrust-to-weight ratio, so the end of the tail nozzle is difficult to Seeing the ring-shaped flame tail, there are only violently expanding thermals.

In just over ten seconds, the temperature in the empty warehouse rose by 5 degrees Celsius. If there were no ice magicians of the water system who condensed pieces of solid ice in advance and piled them up, I am afraid that this facility for the crystal jet engine In no time the warehouse becomes a drying room, or even an oven.

Under the constraints of the unique magic circle, neither the flame nor the hot air flow can directly touch the inner wall of the combustion chamber body. Even if some heat radiation dissipates, it will soon be absorbed by another layer of magic circle using nesting technology. The heat energy loss involved in work is collected again, and fed back to the crystal energy block through energy conversion to improve the efficiency of energy use.

This original heat collection technology makes the body temperature of the crystal energy jet engine much lower than that of the turbofan jet engine, and the service life is effectively extended accordingly.

Each crystal energy jet engine with a slightly different internal design uses fewer components than the F119-PW-100 twin-rotor turbofan engine. Simple does not mean simple, and such a structural design is conducive to increasing production capacity.It is more conducive to reducing maintenance costs and difficulties.

After the No. 1 crystal jet engine ran for about half an hour, the deafening roar finally stopped. The alchemists of the project team immediately replaced the No. 2 crystal jet engine and repeated the test items of the No. 1 crystal jet engine. .Then there is the No. 3 crystal jet engine...

Lin Mo and Qi Fei stood aside, under the protection of the light magic shield to prevent accidents, quietly watching the four crystal jet engine prototypes successfully complete the first stage of testing one after another.

However, regarding the second phase of long-term projects such as service life testing, the two did not continue to read.Instead, he chose to leave early.

Strolling leisurely on the sidewalks on both sides of the criss-crossing main roads in the industrial area, Lin Mo and Qi Fei left the warehouse full of huge roars behind them.

"Four prototype engines, which one do you like!"

As Dragoon Magic Industry is his own industry, in Qi Fei's eyes, the division between public and private is not so obvious.

"Judging from the comprehensive test results of the first stage, I am more optimistic about the No. 3 engine."

Lin Mo's answer is completely from the professional field, without any oblique, one is one.Two is two, no different from the professional habits of alchemists.

"Why not engine #1 with the highest output power, engine #2 with the quietest operation, highest heat collection efficiency, and perhaps engine #4 with the longest lifespan?"

Qi Fei was surprised by this unhesitating choice. The four crystal energy jet engine prototypes represent different design concepts, and each has its own emphasis on performance.But he didn't expect that Lin Mo would choose the No. 3 engine with the highest effective power.

As an engine for military use, the output power and stability have always been emphasized, and the consumption, noise and service life are placed second. The trouble-free running time of some engines is even only a few hundred hours.

"It's the center of gravity!"

"Center of gravity?"

The reason Lin Mo gave was completely unexpected by Qi Fei.

"There is a saying called 'pull one hair to move the whole body', the point of the center of gravity is that one hair, a very important detail." Lin Mo smiled slightly, and then said: "There are two important areas that need to be considered in designing an aircraft. One is the propulsion of the engine, the other is the aerodynamic force, and the two complement each other. But the center of gravity involves both areas at the same time. Especially the latter."

This is entirely the authoritative statement of experts, and the statically unstable design, which is closely related to super maneuverability, happens to have a close relationship with the center of gravity.

"So complicated?"

Qi Fei frowned. Although she learned the alchemy of this world, she knew little about aviation.

"Whether it's building an airplane or flying an airplane, it's not that easy!"

Lin Mo shook his head with a wry smile.

"Is it very difficult? How did you build that forward-swept wing fighter before? According to the two sisters Li Muxin and Li Mubing, you did it on your own."

Qi Fei was a little unconvinced, and the X-8 "Monster" forward-swept wing fighter was the proof, not to mention that there was a gold-type dragon who stole the Earth's technology tree. One person and one dragon could be worth a professional aircraft research institute.

Besides, she also participated in the alchemy reproduction of the "Thang Long" propeller fighter, which doesn't seem to be that difficult.

"The two main engines are old-fashioned, the avionics system is domestically modified, and the aerodynamic design is completely on the shoulders of the predecessors. Otherwise, it will take at least ten or eight years to conduct technical verification. I will smash it into it. The research and development funds are calculated in units of [-] million, adding up, even rebuilding a Dragoon consortium and Yingyuehe (International) will not be a problem."

Lin Mo couldn't help but sighed in his heart. If it wasn't for the hands-on guidance of his teacher, Professor Yan, and the use of the supercomputer computing resources of the "Dark Night" Special Service Brigade to deduce one data by one, he alone would The "Tinder" unit has not been able to fully analyze the half-baked golden dragon, and it is impossible to get out of the "monster" forward-swept deformed wing fighter so quickly.

Compared with Qi Fei and a group of alchemists who copied the ready-made technical materials, the difficulty is completely different.

"Ah! Really?"

Qi Fei was frightened, and then said with a sigh of relief: "Fortunately, you are in charge of the jet project. If it were someone else, I really don't know what to do!"

This foresight enabled Dragoon Magic Industry to avoid countless detours in the completely unfamiliar jet project, and also saved a lot of money.

"Take your time! With me in charge, the jet project should go smoothly."

Lin Mo nodded his head really. It was just a replica of the "Monster" forward-swept deformed wing fighter, rather than redesigning an unprecedented jet fighter. There are a lot of ready-made data for reference. Although the technical complexity is higher than that of the propeller fighter High, but the feasibility is also great, otherwise he would not so easily support Qi Fei and Dragoon Magic Industry to set foot in this unfamiliar field that can represent the comprehensive industrial strength of a country.
