Become the city lord from today

"Tap tap tap……"

Liu Feng and the others came to the Sky Fortress Research Institute. Before they entered, they could see a huge thing on the wall of the courtyard.

"It looks like the progress is okay. Liu Feng chuckled and walked in.

After entering the courtyard, he saw the airship. It was very huge, as big as a building, and many people were working hard around it.

There are three types of airships: rigid airships, Semi-rigid airships and soft airships.

As the name suggests, a rigid airship is an airship made of its internal skeleton, metal or wood, which maintains shape and rigidity. The exterior is covered with skin, and the interior of the skeleton is equipped with many fillers that provide lift for the airship. An independent airbag of gas.

What Liu Feng asked people to build was a rigid airship, which is also the safest type of airship.

Of course, manufacturing is also troublesome and very expensive.

"grown ups."Yuffie trotted over with some dirt on her face.

"Give it a wipe."Mina took out a handkerchief from her pocket and handed it over.

"Thanks."Yuffie took the handkerchief with slightly red cheeks and gently wiped her cheeks.

"How's the progress?"Liu Feng walked towards the airship.

He hadn't seen it for a while. Last time he saw that the outer shell was almost done.

"The front and rear main airbags have been installed, but there are still some regulating airbags that have not been installed."Yuffie quickly followed behind.

"Have you tested it for air leakage?"Liu Feng looked at the people who were suturing.

The interior of the airship is composed of huge air bags, which are divided into two kinds of gases, one is the levitation gas, and the other is air. The seal is helium or ammonia, which is Lifting gas, airships rely on these gases to lift into the sky.

Air is the gas that regulates the rise and fall. The amount determines the rise and fall.

"It has been tested and an extra layer of tarpaulin has been added outside."Yuffie said seriously.

"How's the pod going? How many people can sit? Liu Feng then asked

"Can seat twenty people"

"Have you calculated the ratio of load-bearing weight to air rise?"

"We have already calculated that even if there is a problem with one or two of the adjustment airbags, we can still land safely."

"……"

After several questions in succession

"very good. Liu Feng nodded with satisfaction.

"Sir, the new alloys used this time include. Some of the sub-sections can be replaced with bamboo. The weight can be lighter, save gold coins, and can seat more people."Yuffie whispered.

"It's okay, just remember and come in. Liu Feng said nonchalantly, of course there will be many problems the first time, and waste is inevitable.

"yes."The anxiety on Yuffie's face disappeared.

"Have you tried the machine I sent over?"Liu Feng turned around and asked.

He was talking about the machine that makes helium, or was it delivered after he taught someone to assemble it?

"It has been tried and the gas produced can really make the air bag float."Yuffie shouted excitedly.

She didn't really believe that airships could fly before, even after seeing hot air balloons. After all, airships are too heavy.

After seeing the gas produced by that machine, she She completely believed it, and dreamed that one day she could take an airship to the Kingdom of Aulë, and then secretly take a look at her mother.

"That'll do."Liu Feng looked at the airship, wishing it could be built quickly.

This way, he can fly into the sky and visit more places. He doesn't have to go out for more than ten or twenty days. It's very painful to sit on the boat all the time.

"Sir, can you ask the Rubber Research Institute to help you customize a few large pumps?"Yuffie said timidly.

A pump is needed to adjust the air bag, and this is also a temporary substitute.

"Can. Liu Feng glanced at Niu Si and ordered,"Ask a few more people to come over and help.""

He also saw that the manpower on the airship was a bit overwhelmed.

"yes."Niu Sidao

"How long until it takes off? Liu Feng asked

"It will take at least two months."Yuffie's pink eyes sparkled.

"Two months."Liu Feng frowned. It would be a bit late to fly to the capital.

In winter, he will set off for the capital. When the matters there are finished, it will take about two or three months. Maybe he can start from Wangdu returned to Xiyang City by airship.

He said with a serious face,"Yuffie, please sort out the most suitable airship construction plan as soon as possible. Five airships will be built next year."

The five airships are related to his next plan, which is also a very important plan.

Liu Feng plans to follow the earth's aircraft aviation model for the later role of the airship.

In fact, Liu Feng has a crazy idea, which is to create a A true flying fortress, a thousand-meter-sized flying fortress, and then equipped with bombs, suspended in the sky all year round, can deter some enemies with ulterior motives. The main reason why there is this idea is that airships will not fall down like airplanes when they lose power. As long as there is enough levitation gas in the airbag, the airship can theoretically remain suspended.

Of course, this is just his idea. Whether it will be implemented depends on future development.

"OK"Yuffie said seriously.

"In two days, I will send two machines over, and you can ask people from the military workshop to try to imitate them."What Liu Feng is talking about is the machine that makes gas.

Of course it would be great if it could be imitated. In this way, airships can also be built elsewhere. In the future, airships will belong to the aviation department.

"yes."Niu Si decided to produce a few more lathes, otherwise he would be too busy.
