Chapter 205 Shoggoth Catapult
All work is going on in an intense and orderly manner——

Using the prototype as a template, the engineers spent another three days assembling an identical WS-1.

Xiu mimicked the tail as an interface plug and inserted it into the prototype machine to familiarize himself with how to control the propeller in advance.

Chris led another group of people to start modifying the test ship. Due to the relatively simple structure, the modification was also completed within three days.

And Xia Ye took Xiuji to the warehouse where the wing bones were stored, and let him eat them for three days...

Finally, the exciting moment came——Xia Ye was the main one who was excited, and most of the others were in a state of doubt of "can this really work?"

The two propellers are installed side by side on a disposable bracket at an inclination of 45 degrees, and are fixed with tenons.The brackets are connected to shuttles that slide back and forth along rails buried under the foredeck—thus forming a set of unpowered "catapults."

But the biggest technical difficulty of the catapult is the power system. It must be able to provide a huge thrust in an instant, be able to adjust the thrust according to the quality of the load, and also need to have high reliability and maintainability.

Fortunately, Xia Ye happens to have such a power source...

On the deck, Xiu has already put his legs into the reserved space of the propeller. Unlike the conceptual drawing drawn by Xia Ye at first, Chris considered the engineering feasibility and finally designed the air intake on both sides. the back side of the leg.

This design is reasonable. According to Chris, when Xiu is in level flight, the etheric wind can blow into the air intake along the relatively flat back. If the air intakes are placed on both sides of the legs, The movement of the hands will obviously seriously interfere with the intake airflow, if it is designed on the front side of the legs...

"That's equivalent to the DSI air intake!" Xia Ye blurted out.

"D...S...I? What's that?" Chris asked curiously.She originally wanted to say that the airflow is blocked by the chest, and the air intake efficiency will definitely become lower.

Xia Ye tried her best to recall the knowledge that she didn't know much, and explained the principle and function of DSI in general.

"...In short, the bulge does not necessarily cause obstruction, but it is possible to eliminate the boundary layer, compress the etheric wind, and improve the air intake efficiency. However, this design has strict requirements on the bulge, which cannot be too large or too small. The shape also has to conform to a certain curve, otherwise it's not as efficient as the rear intake."

"Is there such a thing..." Chris was skeptical, "Is this also knowledge learned from another city?"

"Well, it's called 'pneumatics', and it's complicated."

Seeing that Xia Ye said it was serious, Chris finally became a little interested: "If this is the case...we will try it when we are free in the future. It happens that we are the youngest here..." She glanced at it. summer night.

"To the biggest..." She glanced at Yaha again.Of course, the chief mate who was not present did not give up. There are quite a lot of samples of large DSI drum kits.

"...all of them!"

"..." Xia Ye looked at Chris with a smile on her face, thinking about how to rationally use the power of the major shareholder to deduct her salary for this month to zero.

While the two were discussing DSI, Xiu had already made all the preparations with the help of the engineers.Her tail forked into two and were respectively inserted into the ports of the two propellers. The propellers had already entered the fan mode, making a low buzzing sound on the fixed bracket.If it wasn't for the shuttle being fixed at the starting point by the hook, it would have been slowly sliding forward along the guide rail under the thrust of the fan at this moment.

Everything is ready, just need to fix it.

Xia Ye patted the black cat that was sleeping on top of her head, and said, "It's your turn to play!"

"Meow~~" Xiuji yawned, and lazily jumped from the top of his head to the ground.

"In the past few days, you have eaten half of the whale bones in the warehouse, so you have to work hard~"

"Don't worry meow, although my cat hasn't finished digesting it yet, such a light thing is nothing but a trivial matter!"

The black cat jumped, and its body expanded rapidly in mid-air. Then, it split into two groups of equal size and fell towards the left and right sides respectively.

When they landed on the deck, they had turned into two clusters of clawing tentacles, each cluster consisting of five slender tentacles.In the next second, all the tentacles stretched out and moved towards the scroll in the middle of the deck.

There are two legs on the left and right, two hands, and two bodies. The ten tentacles tightly entwine the girl's body symmetrically.

"The thruster engineer confirms!" Xia Ye shouted according to the already designed procedure.

After checking the status of the thrusters for the last time, the engineer responded: "Confirm!" After speaking, he quickly ran away from the ejection area.

"Strike Witch confirmed!" Xia Ye continued to shout.

According to the requirements of the procedure, the items that Xiu needs to check include: whether the "synchronous reinforcement" has been turned on, whether each tentacle is firmly wrapped around the body, and whether the thrusters are operating normally... The girl quickly checked all the items, and pointed to Xia Ye. nodded and shouted:

"Confirm Meow~"

Xia Ye looked at Xiu Ji, "Shuggoth catapult confirmed!"

A few seconds later, a voice came from the tentacles: "Confirm!"

"Current ship speed?" Xia Ye looked at Chris.

"180 knots, cruising speed." Chris replied.

"Okay." Xia Ye nodded, and then announced loudly: "Five seconds to eject! Five, four..."

Accompanied by the sound of the countdown, the ten tentacles distributed in the shape of a "V" tense quickly. The Shoggoths are a powerful race that can easily explode a thrust of thousands of kilograms. The mass is less than 100 kg, which means that the Shoggoth catapult can reach an acceleration of more than 10G!If it wasn't for the "synchronous strengthening", the girl's body would probably be torn apart while being ejected.

"...Three, two, one. Eject!"

Release the hook that fixes the shuttle——

"Shhhhhhhhhhhhhhh—"

There was a sharp and ear-piercing sound, and the shuttle rubbed sparks in the guide rail, and the girl came to the end of the deck in an instant like a stone in a slingshot.With a muffled "bang", the shuttle hit the buffer seat at the end of the guide rail, the impact force caused the tenon to open, the thruster broke away from the bracket, and flew out of the barrier with the girl.

A strong etheric wind hits her face, Xiu inputs instructions to the thruster through the tail, activates the contract in the compression ignition chamber, one second passes, the thruster does not respond, two seconds, three seconds... As time goes by, she His body began to fall, and disappeared in the sea of ​​clouds in an instant.

But she didn't panic, and adjusted her body posture in the air, allowing herself to dive down with her head down, and at the same time activate the compression contract again.

boom--

The roar of ether detonation finally came from under the feet, and the sound of the propeller's operation also became louder. A huge force suddenly appeared, pushing the girl's light body to continuously accelerate.Repair and lock the fan, let the propeller fully enter the ram propulsion mode, and at the same time move the legs less skillfully, so that the direction of the thrust moment changes from downward to upward.

The girl dragged a golden tail flame behind her, drawing a "U"-shaped flight path.

After a while, Xiu rushed out of the thick clouds.

The field of vision suddenly became wider, and when she turned her head, she saw the golden sea of ​​clouds stretching under her feet, reaching to the sky.In the rear, the test ship had been thrown away by her for a long distance, but she could still barely see the cheering crowd on the front deck waving their hands.

An inexplicable feeling rose in his heart, and from this moment on, Xiu completely fell in love with the feeling of flying on the etheric sea.
