In the overload test, the first test is the chest cavity, and the second is the impact of the rapid blood circulation on the brain.

　　 Someone’s blood will flow to the upper body, or all to the lower body.

　　 So these people will be in a coma due to ischemia and hypoxia when they are 6G.

　　 And want to withstand acceleration, blood cannot be controlled artificially, but there is actually a clumsy way to control the oxygen content.

　　 At the beginning of the test, inhale deeply, and then follow the method of 1 apnea, 2 inhale and exhale, 3 hold, 4 inhale and exhale, and 5 hold the breath.

　　 can forcibly increase the oxygen content in the blood in a short time.

　　 and also artificially enlarged the chest cavity to avoid being compressed by the acceleration of the size of the chest cavity.

　　 In the next inhalation, inhale more oxygen, not less and less.

　　 But when Li Changheng did the 9G test just now, because the red blood cells in his body had already reached the limit of the data.

　　 can carry more oxygen, so although the breathing is also accelerated, it is not like other pilots who inhale and hold their breath quickly.

　　In other words, just by looking at this point, you can see that he was not at the limit when he was in 9G.

　　 didn't even reach the upper limit.

"let's start"

　　 "25 second overload test, are you really sure?"

　　 Li Changheng replied clearly again, but there was no beeping sound in the test field for a long time.

　　 Jim and Dick Reston couldn't help but look up at the test supervisor.

　　 And the mustache officer thought quickly in his mind, some data that Grumman and General Dynamics told him.

　　 If Li Changheng knew about it, he would definitely think of F16 and F14 Tomcats.

　　F16 is the first fighter that can make 9G overload flight maneuvers in the future.

　　In other words, pilots who want to fly F16 have to withstand at least 8G overload.

　　 So once Li Changheng bears the 11.5G overload, he is definitely the most suitable F16 test pilot in the future.

　　 You can fly as you want. You don’t have to worry about the limits of the human body. It is impossible to test the full performance of the aircraft.

　　 But the airplane simply cannot reach the limit that his body can withstand.

　　 As for the F14 Tomcat, it's actually the same.

　　 "SIR?"

　　 Hearing Jim's voice, the test supervisor recovered his mind and picked up the walkie-talkie to let the engineering staff enter the venue for inspection.

　　 In case the theoretical acceleration can reach 16G, but the machine has never accelerated above 12G, there will be problems.

　　 More than ten minutes later, not only Jim’s five people squeezed into the control room.

　　 Even General Kenny Chung and other high-level bases entered the control room.

　　 If Li Changheng can really break the record, that would be a good thing for the Air Force of the National Guard.

　　 Even General Kenny Chung and others are still thinking that in the future, when they undergo flight confrontation training, they might win the Navy once more.

　　 A rising sound of "beep beep" sounded.

　　 Li Changheng reached out and held the fixed flight control stick.

　　 took a deep breath and felt his body rush forward rapidly, his entire back was attached to the driver's seat.

　　 At 1 second, 5 seconds, 10 seconds, 15 seconds, I instantly felt like my chest was being squeezed by something.

　　 Instinctively, I inhale quickly and deeply, then hold my breath and change my breath.

　　 Then did I feel less uncomfortable.

　　 Even when he subconsciously made a fighter jet, the pilot in a high-speed turn would inevitably turn his head to check the enemy's position.

　　 God.

　　 A group of people looked at the console instrument, and the 11.5G or even the 12G red light would occasionally light up.

　　 In other words, it is at least about 11.8 to be accurate.

　　 The people present suddenly reduced their breathing for fear of disturbing Li Changheng.

　　 But a knowledgeable person like Jim understands that Li Changheng sitting in the tester is not at the limit at all.

　　 Even he can easily simulate real air combat and check the movements of enemy aircraft from left to right.

　　 If the speed of the instrument hadn't been set at the beginning, Dick Reston would like to adjust the speed to 12 or even 13, to see where Li Changheng's limit is.

　　 When the number on the average speed timer jumped to 9, the test supervisor immediately pressed the deceleration button.

　　 There was silence in the control room for five or six seconds, and then there was a sudden applause and cheers.

　　 This data is definitely American, the highest record of all pilots at this time.

　　 Someone will be able to break it in the future, and there may be people in the world who can test the existence of 20G.

　　 But at least among fighter pilots, Li Changheng broke the record.

　　 Dick Reston looked back at Jim and said, "After 5 days with your new boss, go to Houston for ice bucket, three-dimensional rolling ring, overweight and claustrophobic testing."

　　 "Passed?"

　　 Jim looked at Reston in surprise, "Are you sure?"

　　 "Come on, Jim".

　　 Reston looked at him dissatisfiedly and said, "We all know the manned moon landing plan. At the beginning, only the Apollo 14 spacecraft was planned.

　　 At present, 5 of the 6 astronauts on the 11th and 12th do not plan to take off again, and the permission of the three of you to take off has been suspended again.

　　 There are only 7 people who can execute the 14th spacecraft.

　　 But 4 out of these 7 people have mental problems of varying degrees.

　　I can’t avoid this kind of record-breaking person. "

　　 Speaking of this, Reston stared at Jim and asked, "I will let you take off now, do you have enough courage and mental preparation to sit in the command cabin on the rocket?"

　　 Jim opened his mouth, but in the end he couldn't speak, he could only silence with a sad expression.

　　 It is really lucky to come back alive, it can even be said to be a miracle.

　　 After the rocket lifted off, the propulsion modules of the first and second engines were very smooth, but they flew to the moon for two days when the last propulsion module pushed them to the moon, and they were about to reach the lunar orbit.

　　 The oxygen tank exploded suddenly in the service cabin.

　　 Fortunately, although the explosion affected the command module, the lunar module was not damaged at all.

　　 If there is any tiny piece of debris and the outermost layer of the lunar module, only the insulating layer as thick as playing cards will touch it.

　　 When they land on the earth ~lightnovelpub.net~ they will be violently rubbed against the air, and they will be born at a high temperature of 3,000 to 4,000 degrees and burned to ashes.

　　 And in the case of insufficient power, the parachute bounced automatically without any problems.

　　 Otherwise, they would crash into the sea like a meteorite, and then be shaken to death.

　　Also, because of the lack of electricity in the lunar module, the three of them had to stay in space, only keeping communications, and all other electronic equipment turned off.

　　 In the cold and dark space, I stayed up nervously for two days and two nights.

During the 　　 period, I also experienced the lunar module. At the beginning of the design, only the carbon dioxide emissions of the two astronauts were considered.

　　 At that time, there were three people sitting inside, and the purification equipment of the lunar module could not be cleaned, causing the carbon dioxide concentration in the cabin to become higher and higher.

　　 The three of them almost suffocated to death.

　　 If it were not for the efforts of a dozen scientists, lunar module manufacturers and designers in the NASA command center, to use the equipment in the lunar module to improvise a simple filter.

　　The three of them really can't return to the earth.

　　 Jim now only needs to remember the fear in his heart, and let him know that he hasn't come out of the shadows yet.

　　 Knowing the content of the astronaut assessment, he knew that it would be difficult for him to get into the spacecraft anymore.

　　 I thought that Jim had to think about the rest of his life.

　　 "If my boss passes all tests, the training and assessments in the next four months pass with excellent results.

　　 How likely is he to board the 14th spacecraft? "
