Chapter 211 Failed Attempt

Previous page        Return to Catalog        Next page

    After listening to the chief¡¯s words, Zheng Quanli was not surprised, because Hong Shengli¡¯s report had already put forward his own opinions on other applications of drones, including terrain surveying.

    Judging from the practical ceiling of the UAV of nine kilometers, the cruise time of more than four hours, and the payload of up to 180 kilograms, it does have the potential to complete terrain surveying and mapping, but

    "Chief, I hope to see the actual situation to judge the specific situation. Of course, most of us are not professional in this regard. It is best to invite an expert from the aerial surveying and mapping brigade. This may be safer."

    The chief thought for a while and nodded: "Well, it's very appropriate for you to consider this. After all, the nature of the tasks of meteorological monitoring and aerial surveying and mapping are different, and the requirements for the platform must be different Well"

    After saying that, the leader paused, then picked up the tea cup and took a sip, then raised his head and looked at Zheng Quanli: "But anyway, the Xingzhou Force's drone is a good idea. Now the headquarters is in a hurry to get a new map. We  There is no need to hide your secrets, so you can go back and get a feasibility report on drone surveying and mapping, and I will sign it. I believe the headquarters will take it seriously."

    ¡­¡­

    The commander was right. After receiving the report from the military region, the headquarters did attach great importance to it. To be more precise, it had to pay attention to it. There was no way. Topographic surveying and mapping were already tight on time and the task was heavy. At this juncture, a plane used for surveying and mapping  The IL-18 was lying down.

    The task of terrain surveying and mapping suddenly became difficult. In desperation, the headquarters could only use stupid methods to mobilize the surveying and mapping teams of each subordinate unit, hoping to use manpower to make up for the dilemma of missing a platform.

    It¡¯s a pity that sometimes, the gap between meager manpower and huge technological advantages is really big. Although the IL-18 is old, with imported terrain surveying and mapping equipment, it can complete accurate surveying and mapping of 6,000 square kilometers in half a day.

    The same scope would require at least three surveying and mapping teams of 80 people, working day and night for nearly a month to complete.

    The entire East China and South China areas are more than one million square kilometers, and even if all the surveying and mapping brigades of the army are filled in, it will not be completed in one or two years.

    The problem is that the maps in the hands of the army are on the verge of being eliminated, and some places have begun to affect normal military activities. If we wait another one or two years, will the army still defend our country?

    Therefore, in addition to racking their brains to find ways, the surveying and mapping department at the headquarters also attaches great importance to other units and fraternal forces as long as they have any methods that can help improve the efficiency of surveying and mapping.

    People¡¯s war requires the collective wisdom of the people.

    So after receiving Zheng Quanli¡¯s report, he transferred it to the aerial surveying and mapping brigade without a second thought. Soon the aerial surveying and mapping brigade sent their aviation engineer Xue Weidong to see the situation on the spot.

    Xue Weidong has become numb to this and has no choice. He has done more similar on-site inspections during these days than he can count.

    He has looked at all the Yun-5, Yun-7, and Yun-8. Among them, the most recent success was the modification plan for the Yun-8. As a result, they conducted several test flights on the Yun-8 and found that the Yun-8 did not have a pressure-resistant cabin design.  This limits the use of the aircraft at high altitudes, and in some aspects it is not as good as the high-altitude performance of the IL-18 with a pressure-resistant cabin.

    This made the aerial surveying and mapping brigade, which was responsible for multiple tasks, have no choice but to give up.

    After that, they turned their target to the "Trident" passenger aircraft that had been delivered to civil aviation, because this aircraft is very suitable for the needs of the aviation surveying and mapping team in terms of size, flight performance, and even modification potential.

    However, as soon as this idea came up, it was rejected by the superiors. The reason is very simple. This aircraft has had many accidents since the late 1970s, and no less than two of them were destroyed.

    Nowadays, both the Air Force and civil aviation are gradually phasing out this model. Even if their aerial surveying and mapping brigade cannot use the new model, they can't use something that is ready to be eliminated due to poor safety.

    Although the "Trident" passenger plane is not available, Xue Weidong has not given up on continuing to search in civil aircraft. For example, they have focused on two civilian passenger aircraft, Boeing 707 and McDonnell Douglas 80, imported from the United States some time ago.

    To this end, a detailed feasibility report was submitted to the superiors, who were also very supportive of this. As a result, before they could take any action, people from Boeing and McDonnell Douglas came to the door after getting wind of the matter.

    They first took out the civilian procurement contract and pointed to the clause prohibiting military use and told Xue Weidong and the others that civilian airliners are for civilian use. Without their consent, the user country cannot carry out militarized modifications at will, otherwise they will cancel the sale of the aircraft model according to the contract.  Later maintenance and parts supply.

    Xue Weidong and the others don¡¯t care about the contract. They bought the plane with money, and it¡¯s not up to them to use it however they want.Do you have the final say?  But if the supply of maintenance and parts is cut off, it will be fatal. There is no way. Many of the equipment on other aircraft are unavailable in China. Simple repairs are fine, but complex overhauls have to be returned to factories in the United States.  If this is interrupted, what will happen to the newly developed civil aviation?

    Seeing Xue Weidong and others wilting, the Americans immediately changed the subject, took out a lot of information on special aircraft modified for the United States, and told Xue Weidong and others, why bother so much, just buy our modified aircraft, they are world-class.  , no bragging, no slander, as long as 60 million US dollars per unit, it is guaranteed to allow the Chinese Air Force to enjoy the pleasure of modernization.

    The information is very exciting, and the performance is also eye-catching, but the price is a pity It is not enough to package and sell Xue Weidong and the others. For 60 million US dollars per unit, how much is the Air Force's annual military expenditure?  If you buy one like this, everyone in the Air Force will not even have to eat.

    Since then, the idea of ??using foreign passenger aircraft to modify it has been completely blocked.

    We have no choice but to go back to China. If someone can¡¯t do it, can we make up for it if there is no one?  So Xue Weidong and others brought over the Changkong-1 UAV used for air force equipment testing. After all, from the perspective of range, this kind of UAV with a range of more than 500 kilometers is still very impressive.

    After taking it over and modifying it, I tested it several times. The effect cannot be said to be non-existent, at least it is more efficient than manual surveying and mapping. However, the battery life of more than an hour is really too little, and the hard landing method is even more torturous.  The additional terrain surveying and mapping equipment are imported precision instruments that cannot withstand being dropped.

    As a result, the Changkong UAV was designed to be very unrestrained due to its original nature as a target drone. Therefore, every time the detection equipment was disgraced by the rough landing method of the Changkong UAV, after two or three sorties, the detection equipment was not scrapped even if it was not scrapped.  , the sensitivity is also greatly reduced.

    In addition, the turbojet-6 jet engine equipped on it has a high failure rate. Each survey requires a large number of maintenance personnel to accompany it. The fuel consumption is also astonishing. Not only is it inconvenient, but the cost of use is also high.  He remains so high that Xue Weidong now gets a headache whenever he hears the word drone.

    Now that he received the mission to go south, he was looking at drones. Xue Weidong's brain was about to burst. Even the Changkong series of drones in the army, which represent the domestic advanced level, could not be used. What other drones could satisfy aerial surveying and mapping?  The team's request?

    It¡¯s a pity that the superior¡¯s order insists on him going, so let¡¯s go and have a look. Anyway, he has been to so many places, and this is not the worst

    Sitting in the swaying jeep, Xue Weidong couldn't help but think
