Chapter 1249

The use of Aviation Tools, except origami aircraft, requires the joint efforts of a group of people, such as real flying aircraft and helicopters, such as taking off hot-air balloons.

After all the hot-air balloon equipment was ready, a group of four and a group of six began to quickly cooperate to splice them.

The first is to spread the balloon on the ground. They did it very quickly. A group of four finished it in about ten minutes.

Another six person group assembles the hanging basket, which is more complex because it needs to install the hanging basket shell, install the safety bin, configure the burner and blower, etc.

They are all well-trained veterans, almost completed at the same time, and then they cooperate to connect the airbag with the hanging basket put aside.

At this time, the small engineering vehicle following the scooter began to work, injecting helium into the deflated air bag on the ground. In this way, the air bag began to rise slowly and get higher and higher. Until there were five or six meters, the blower in the basket began to work and the burner slowly sprayed fire out.

The light gas acts together with the hot air, and the rising speed of the hot air balloon is accelerated. In this way, when the air bag takes off completely, the preparation work is almost done.

Qin Shiou looked at the hanging basket dangling and was excited. He said, "can you go up now?"

He looked at the time. In fact, it didn't take long, less than an hour and a half, and this was the first time to take off. After that, the hanging basket was assembled. There was no problem after inspection. Inflate the air bag and fly in an hour.

Johnson shook his head and said, "no, Mr. Qin, we still need to debug the equipment. We need to debug the GPS navigator, satellite phone and radio station one by one. After there is no problem, we can contact the ground service car before we can take off."

Qin Shiou said in amazement, "is it so complicated? When I read the introduction, didn't it say that two people could complete the takeoff of the hot-air balloon? "

He said that the two men were pilots and co pilots, who were used to control hot-air balloons.

Johnson shook his head and introduced him, "being able to take off is different from flying well! In the eyes of our professionals, there are at least five people in a complete hot air balloon flight team! "

"So much?" Qin Daguan took a breath. He felt that it was not easy for him to fly this hot-air balloon.

Johnson continued, "yes, quite a lot. First, we need two pilots and co pilots, second, we need two ground attendants, and we need a health worker. If it's a special-shaped ball, it's even more troublesome. The ground service needs 9 people! "

"Why do you need a health worker?" Senior official Qin was helpless. He didn't introduce it when he checked the information.

Johnson smiled and said, "the change of flight altitude will cause changes in pressure, temperature and air density, which will cause people's discomfort, so it's best to have a health worker to monitor blood pressure, blood glucose, blood lipid and other physiological data."

After some testing, the engineer who came with Johnson gave him a thumbs up, which means that the hot-air balloon is OK and can fly.

Qin Shiou asked, "is it OK this time?"

Johnson smiled and said, "yes, it's OK. There's no problem at all."

Qin Shiou nodded and took the lead in getting on the hot-air balloon. There were two middle-aged people waiting inside. They were the pilot and co pilot of the flight.

Seeing Qin Shiou's candid on the hot-air balloon, Johnson said, "Mr. Qin is really brave. Among the people I know, few people dare to go up without a test flight when they see a hot-air balloon for the first time."

Originally, when Qin Shiou bought a helicopter, the pilot drove the helicopter for several laps and proved that there was no problem before pulling Qin Shiou up.

However, hot-air balloons are different from helicopters. As long as the operating rules of hot-air balloons are strictly observed, there will be no problem, because the rising power of hot-air balloons is the hot gas generated by the combustion system. If the combustion system cannot generate hot gas, the balloon will become a parachute and naturally land slowly.

Even if the airbag is broken, due to material reasons, as long as the airbag is not hit by a missile or torn by a tornado, it will not have a big gap at once. In this way, a burner continues to produce hot air to supplement the gas leaked from the gap, which can still ensure the normal landing of the balloon.

Of course, if the air bag of the hot-air balloon is broken without natural and man-made disasters, and the burner cannot be used at the same time, the people on it are really dangerous, but the probability of encountering this situation is no greater than one billion in the lottery.

Now hot air balloons have been confirmed as the safest aircraft by the international aviation Federation. Qin Shiou knows this, so what's to be afraid of?

In addition, Qin Shiou's reason for going to the hot-air balloon is not only curiosity, but also because he brought something - an ultra long banner sweeping together and requiring him to hug. This banner is to be hung on the hot-air balloon.

On the hot-air balloon, the two pilots began to be busy. One contacted the ground service car by radio, and the other checked the altimeter, lifting speedometer, thermometer, pressure gauge, anemometer, etc.

The burner began to increase its firepower, and a super flame two or three meters long burned straight. The powerful hot air rose, and the hot-air balloon suddenly began to accelerate.

Johnson explained to Qin Shiou: "we don't charge enough helium. Because the airbag is used for the first time, we have to give it a time to adapt to the tension, so we need to rely on the burner for this flight."

The fuel used for Archangel F2 generation am hot-air balloon is propane and liquefied gas, and the burner is a high-energy compressed gas combustion furnace with heating capacity 500 times stronger than that of ordinary household gas furnace, which can maintain the fire all the time and resist force 8 strong wind.

If the burner strikes, there are two combustion systems on standby on the hot-air balloon, which can be turned on at any time.

In fact, this is not a good time for hot-air balloons to take off. It is best to fly this thing just after the sun rises or an hour or two before the sun sets. That time is usually the time when the stroke is the most calm and the air flow is the most stable.

Hot air balloons are not really driven. They go with the wind. However, because the wind has different directions and speeds at different altitudes, the pilot can choose the appropriate altitude according to the direction of flight needs.

Now it's just the north wind. The farewell island is located in the south of St. Johns. You can fly at ease. This is also the reason why the pilot chose to take off now. Otherwise, if you want to fly a hot-air balloon to the farewell Island, you need help.

Qin Shiou used to have acrophobia. He took helicopters and aerial tractors in the fishing ground every day. His acrophobia eased a lot. The hot-air balloon didn't fly too high, so he could accept it.

Flying in the air, he looked down and saw St. Johns getting smaller and smaller under his feet.

St. John's is a port city built on the sea, so the terrain is uneven. There are many uphill and downhill in the city, and some houses are slightly inclined. This is particularly clear from a high point of view.
