Tang Hua asked Qian Xuesen who was also in the headquarters.
“因为弹体材料和发动机有了一些优化，300公斤战斗部状态下射程从600公里提高到660公里，500公斤战斗部时射程从400公里提高到450公里。6月份发射TK-3的轨道高度数据也间接印证了这个数据是没问题的。就看你的惯导系统工作精度有多高了。”
Tang Hua: "The circular probability deviation of the initial V-2 is 8000 meters, and the late model is only increased to 3000 meters. There is no doubt that our missile surpasses the V-2. Specifically, the circular probability deviation of Dongfeng-1 is lower than 1000 meters is a matter of high probability. As for the limit accuracy, it may take a few more rounds to test out actual measurement data.”
……
At the missile launch site, two Dongfeng-1 short-range ballistic missiles have already stood on the launch pad.The two launchers meet at 350 meters.Next to each missile are several flat tank trucks, and several soldiers in full chemical protective suits are operating step by step to refuel the missiles.
The appearance of Dongfeng-1/TK-3 is extremely simple.The pointed nose and the main part of the projectile body are standard cylinders, the tail of the projectile has four fins, and the buttocks are the four nozzles of the rocket engine-strictly speaking, it is a rocket engine with four nozzles.
The missile is 12 meters long, only a little longer than the TK-2 sounding rocket, but almost twice as thick, and the aspect ratio is as low as 9:1.This makes Dongfeng-1 look more quality.
"Missile fuel filling is complete!"
After hearing the report from the launch site, the commander-in-chief, Lao Zhang, connected Zhangye: "The missile landing area is ready."
"The Zhangye target area has entered a state of combat readiness."
Launch site: "Missile ready!"
Following Lao Zhang's order, the tail of Dongfeng-1 at the launch site sprayed out red flames, and the missile lifted off the ground, slowly climbed and accelerated.
Although the thrust of the rocket engine is roughly constant, the mass of the missile continues to decrease due to the rapid consumption of fuel, so the acceleration of Dongfeng-1 is getting higher and higher.After a while, it flew out of the visual distance of Wuliangsuhai Experimental Base.
Now the parameters of the missile rely entirely on radar measurement, control and tracking to master the data.
Tang Hua felt that he could ignore the radar data now.When the missile disappeared from view, he stepped down from the observation deck outside the headquarters and looked down at his watch.Qian Xuesen calculated the flight time of Dongfeng-1 from ignition to hitting the target.
In the hall of the general headquarters, the radar station of Urad Middle Banner watched the missile fly out of the atmosphere, and then Bayannur tracked the radar station to relay.In the middle of the missile's flight, there are two radars that can illuminate the missile at any time, and there are constant voice reports from the radar station at the headquarters.
"The tracking of the Zhangye radar station is normal." "The missile re-entered the atmosphere, and the track was normal." "The missile splashed down, and the radar signal disappeared."
The missile flew 660 kilometers and landed in Inner Mongolia.
In the open Gobi between Ovoot and Wuzemu, the target landing area here draws two large concentric circles. The experimental troops have been staying in the underground bunker with a thick concrete roof and a 6-meter-thick soil layer. There is only one There was a sentry on the watchtower still looking out.
The two missiles landed heavily in the Gobi desert, one after the other, about 30 seconds apart.The sentry on the watchtower saw the trajectory of the two missiles with the naked eye.
The landing of the missile was a mobilization order. The test team climbed the stairs as quickly as possible, from the bunker to the ground, drove out 4 jeeps, and searched for the wreckage of the fallen missile under the guidance of the walkie-talkie of the watchtower sentry.
……
The report of the target area was sent to the general headquarters, Lao Zhang and two staff officers immediately took out the map of the target area, and marked the landing points of the two missiles on the map according to the oral report.
The first missile deviated from the center of the circle by 810 meters, mainly due to lateral deviation.
The second missile... deviated from the center of the circle by 200 meters, and the deviation mainly occurred in the longitudinal direction.
"Sure enough, the two shots did not exceed 1000 meters." Qian Xuesen said.
Tang Hua: "Although the accuracy of the second bomb is scary, let's fire a few more rounds in the future... The range of 660 kilometers is really good."
……
"Old Qian, if I didn't want to watch you torture monkeys, I would have withdrawn to Beijing first," Tang Hua said to Qian Xuesen with a smile in the payload assembly room of the test base, "Look at the time, today is July 7 Already, the Beidaihe vacation cycle has already begun.”
Qian Xuesen: "I know. Besides, I have already informed my lover to take the baby to Beidaihe first."
The little monkey's eyes were marked with the word "innocent", but it was useless. Several people worked together to fix it, and tied electrodes, sphygmomanometer, heart rate detector, heart computer and electrical equipment all over the body, stuffed it into the load compartment.
"I personally supervised the folding of the main parachute and auxiliary parachute, so don't worry." Qian Xuesen patted the monkey's head.
Tang Hua: "Maybe he is Monkey King. Even if the parachute fails to open, he can fly hundreds of miles away and land in a somersault."
After the load compartment is assembled, it is immediately transported to the launch site by car, and then hoisted onto the launch pad of the launch site.Three minutes before being installed on the head of the TK-3 sounding rocket, the airtight compartment of the load compartment entered a fully enclosed state, and the breathing oxygen consumption of the monkey and the rabbit below was all provided by the sodium peroxide plate in the airtight compartment supply.Sodium peroxide board can supply 3 hours of breathing, it should be no problem.
Prior to this, the TK-3 sounding rocket had been refueled.After the load compartment is installed, the fairing is put on, and all personnel and vehicles are evacuated, TK-3 enters the preparation stage for ignition and launch.
"Last 10 seconds to prepare. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, launch!"
……
"Old Qian, have you watched "Girl in the Moon Palace", a sci-fi feature film made in Germany in the past few years." Tang Hua asked Qian Xuesen.
Qian Xuesen: "I should have watched it when I first went to America."
Tang Hua: "Do you remember that when the big rocket inside was launched, the scientists counted backwards from 10 to 0?"
"I remember what you said, and it's true."
"I think this is better. It is simple, clear and accurate. The main reason is that the numbers reported are getting smaller and smaller, which makes people concentrate and create a sense of urgency."
Qian Xuesen also pondered for a while, "The last 10 seconds before the launch is going to use a countdown timer... Interesting. You can try it next time."
At the launch site, TK-3 has been flying straight up after leaving the ground, without turning at 5000 meters.
Fly and fly and you can't see it.You have to fly up to 170 kilometers and then fall down. When you fall to a height of [-] meters, you open the small umbrella and the big umbrella in turn, and finally land softly. It doesn't take half an hour to get down.
"Old money, the White House created the 'teapot' committee, the Strategic Missile Review Board, to possibly investigate why the USAF's strategic missile program has been slow. Brigadier General Bernard Schriever was removed from the Air Force Staff , maybe the U.S. Air Force will also move to avoid being held accountable by the president and Congress."
Qian Xuesen: "Their RTV-A-2 Hiroc project started in 1946, and the Jet Propulsion Laboratory gave them a rocket plan in 1949. It has been 9 years now, and the progress is not as good as expected."
Tang Hua said with a smile: "Compared with ballistic missiles and bombers, the U.S. Air Force still likes bombers a little more. Bombers require more people, and the Air Force will have a larger establishment, a higher status of the service, and higher funds to pass them on."
In 1954, the B-52 bomber entered the stage of rapid mass production.
At this time, the B-52 was not a "missile truck" that threw cruise missiles at a distant place to abuse small countries. It was used to forcibly attack the Soviet air defense system and drop nuclear bombs to destroy the country.Apparently at this time, the U.S. Air Force pretended not to see the power of the S25 anti-aircraft missiles - thinking in his heart, "S25 is a fixed launcher. I can't get in except Moscow, and all other places in the Soviet Union can be blown up." After talking for a long time, he himself believed up.
The stubborn U.S. Air Force has also been developing bombers that fly higher and faster, challenging anti-aircraft missiles and interceptors. The flying altitude of the B-52 can make the MiG-15 very uncomfortable. The B-58 can fly at twice the speed of sound.Then came the XB-70, then the B-1A, and then the USAF finally bowed to reality and went to the B-2.
Qian Xuesen: "There is still a problem with the development of ballistic missiles in the United States. It is not step-by-step and directly hits the intercontinental range. But this may also be related to the fact that the United States is not very meaningful in developing and equipping intermediate-range missiles. Whom are medium-range ballistic missiles used to hit? Canada or Mexico. "
"However, going directly to the intercontinental missile will also have associated benefits. This thing does not contain a nuclear bomb, it is a space delivery vehicle." Tang Hua said, "Friends in the Soviet Union said that at the end of last year Korolev proposed to the Minister of Defense Industry that man-made The development plan of the satellite. And the Soviet Union is making preparations for the implementation of the project."
Earlier than making recommendations to the Minister of Defense Industry, in May 1954, the Soviet military issued the task of developing the R-5 intercontinental missile.That is, in May, Sergey Korolev began to formulate and write a plan for the launch of a satellite.Korolev also emphasized that the launch of orbiting satellites is an inevitable stage in the development of rocket technology.
Earlier than 1954...that probably goes all the way back to Nikolai Tikomilov's laboratory.
In short, the United States and the Soviet Union did start a few years earlier in terms of large rockets and artificial satellites, and this is an inherent advantage that cannot be changed. From 1957 to early 1958, the United States and the Soviet Union launched artificial satellites one after another, but Tang Hua felt that although he could not grab this first, he could grab a more practical first: the first artificial satellite with actual production, scientific research or military purposes.
Well, the first artificial satellites of the United States and the Soviet Union were experiments.The Soviet satellite weighed more than 80 kilograms and used batteries.When the battery power is exhausted, the radio signal released to the outside world is terminated.
The first artificial satellite of the United States was ridiculously small. Khrushchev even laughed that the American satellite hit a baseball into space.
……
The TK-3 sounding rocket did not go straight up and down. When the payload cabin re-entered the atmosphere, the tracking radar had confirmed that it had arrived at a place 100 kilometers west-south of Wuliangsuhai Sea, which was relatively close to Wuyuan County.
