Section 985 - Technical Difficulty

Compared to turbofan jet engines that use jet fuel, crystal jet engines actually operate more efficiently and have a lower attrition rate. Pen, fun, and www.biquge.info

The project team selected a light natural vegetable oil with good low temperature fluidity as the fuel matrix, and gave purification, hydrogenation and thickening and oily blending treatment processes, and poured into the turbofan combustion chamber through the catalytic medium pipeline, and increased the atomization efficiency and calorific value by the wind and fire spell fields.

Before the completely burning flame leaves the tail nozzle, it has been sprayed out by the turbine and the local wind system spell array into high-speed and high-pressure airflow, so as to obtain an extremely efficient thrust-to-weight ratio, so it is difficult to see the annular flame tail at the end of the tail nozzle, only the intensely expanding hot air flow.

In just over ten seconds, the temperature in the empty warehouse had risen by 5 degrees Celsius, and if it weren't for the water ice magicians condensing pieces of solid ice in advance and piling them up, I'm afraid that this warehouse for crystal energy jet engines would immediately become a drying room, or even an oven.

Even if some of the heat radiation escapes, it will soon be re-collected by another layer of spell circles using the nesting process to re-collect the heat energy loss that does not participate in the work, and feed back to the crystal energy block through energy conversion, so as to improve the efficiency of energy use.

This ingenious heat acquisition technology enables the body retention temperature of the crystal energy jet engine to be much lower than that of the turbofan jet engine, and the service life is effectively extended.

Each Crystal Injection Engine with a slightly different internal design uses fewer components than the F119-PW-100 twin-rotor turbofan engine, which is simple and does not mean simple, which is conducive to increasing production capacity and reducing maintenance costs and difficulties.

After about half an hour of operation, the No. 1 Crystal Injection Engine finally stopped its deafening roar, and the alchemists of the project team immediately replaced the No. 2 Crystal Injection Engine, repeating the test items of the No. 1 Crystal Injection Engine, followed by the No. 3 Crystal Injection Engine......

Lin Mo and Qi Fei stood aside. Under the protection of the light spell shield to prevent accidents, quietly watch as the four prototypes of the Crystal Energy Jet Engine successfully complete the first phase 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 watch, but chose to leave early.

Leisurely strolling along the sidewalks on both sides of the main bypass road that crisscrossed the industrial area, Lin Mo and Qi Fei left behind the huge roar of the warehouse.

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

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

"Based on the results of the first phase of testing, I am more optimistic about Engine 3. ”

Lin Mo's answer was completely from the professional field, without any beating around the bush. One is one, and two is two, no different from the professional habits of alchemists.

"Why isn't Engine 1, which has the most power output, Engine 2, which operates the least noisily, Engine 4, which has the highest thermal collection efficiency and perhaps the longest service life?"

This unhesitating choice surprised Qi Fei, the four prototypes of the Crystal Energy Jet Engine represent different design concepts, each with its own emphasis on performance, but he did not expect Lin Mo to choose the No. 3 engine with the highest effective power.

As an engine for military use. Historically, the emphasis has been on power output and stability, over consumption, noise and service life, and some engines have a trouble-free run time of only a few hundred hours.

"It's the center of gravity!"

"Center of gravity?"

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

"There is a saying called 'pull a hair and move the whole body', and the point of gravity is that hair. A very important detail. Lin Mo smiled slightly, and then said: "There are two important areas that need to be considered when designing an aircraft, one is the propulsion of the engine, and the other is the aerodynamic force. The two complement each other, but the focus is on both areas, especially the latter. ”

This is entirely the authoritative statement of experts. The static unstable design, which is closely related to super-maneuverability, happens to be closely related to the center of gravity.

"So complicated?"

Qi Fei frowned, although she had learned the alchemy of this world, she knew very little about the field of aviation.

"Whether it's building an airplane or fighting a plane, how can it be so easy!"

Lin Mo smiled bitterly and shook his head.

"Isn't it difficult? How did you build that forward-swept wing fighter before, I heard the two sisters Li Muxin and Li Mubing say, you made it by yourself. ”

Qi Fei was a little unconvinced, the X-8 "Demon" forward-swept wing fighter was proof of this, not to mention that there was a gold-based dragon that stole the earth's technology tree, and one person and one dragon could be worthy of a professional aircraft research institute.

Moreover, she also participated in the alchemy reproduction of the "Shenglong" propeller fighter, which does not seem to be so difficult.

"The two main engines are to grab the old United States, the avionics system is domestically transformed, and the aerodynamic design is completely standing on the shoulders of the predecessors, otherwise it will take at least ten or eight years just to carry out technical verification, and the research and development funds I threw into it are calculated in units of 100 million, and the cumulative amount adds up, even if it is no problem to rebuild a dragoon consortium and Yingyuehe (International). ”

Lin Mo couldn't help but sigh in his heart, if it weren't for the hand-in-hand guidance of his teacher, Professor Yan, coupled with the borrowing of the supercomputer computing resources of the "Dark Night" special service team, and the deduction of data by data, it would have been impossible for him to get the "Demon" forward-swept transformer fighter out so quickly with him and the half-hung gold-based dragon who had not even been able to thoroughly analyze the "Tinder" unit.

Compared with Qi Fei and the alchemists, who originally copied the ready-made technical materials, the difficulty was completely different.

"Really?"

Qi Fei was frightened, and then said as if relieved: "Fortunately, you are in charge of the jet project, and if it is someone else, I really don't know what to do!"

This foresight saved Dragoon countless detours and a lot of money on a completely unfamiliar jet project.

"Take your time! With my watch, the jet project should go well. ”

Lin Meng nodded sincerely, just a replica of the "Demon" forward-swept deformed wing fighter, instead of needing to redesign an unprecedented jet fighter, with a large amount of ready-made data to refer to, although the technical complexity is higher than that of the propeller fighter, but the feasibility is also very large, otherwise he would not so easily support Qi Fei and Dragoon Magic Industry to set foot in this strange field that can represent the comprehensive strength of a country's industry.
