    The answer is obvious. Those companies that rely on their old capital, like to make quick money and rely on directive orders from the country and the army obviously cannot do it.

    If nothing else, Ascendas Group¡¯s annual research and development funds are enough for them to last for several years. If they persist for several years, the accumulated results are not to mention overwhelming, but they are also much richer than ordinary companies that rest on their laurels.

    Especially in terms of optical imaging, so many years of unremitting research by the North China Institute of Optics, a subsidiary of Ascendas Group, have finally come to fruition. Especially after receiving the support of experts from the Soviet Union in China, the technical level has improved by leaps and bounds.

    The most typical one is the visual enhancement system that allowed the Y-15plus to successfully land on the shooting range island at night without support during the island landing exercise.

    This system is divided into two parts, one is the detection system and the other is the display system.

    The detection system uses the infrared principle to accurately identify infrared signals emitted by running objects, buildings, parked vehicles on the ground, and even surrounding plants, so as to determine the correct location of running.

    Of course, in order to achieve this level, the accuracy of the infrared sensor must be high. Thanks to the progress of Ascendas Group in aerospace technology in the past two years, the North China Optics Research Institute has successively made breakthroughs in infrared optical components, making it  The infrared vision augmentation system produced can measure temperature changes of five thousandths.

    With such sensitive infrared photosensitive components, combined with the comprehensive utilization of system sensors and advanced algorithms integrated by Ascendas Group, these five-thousandth temperature changes can be continuously displayed on the display system in the form of "photographs"  Up and down continuously, just like what you see with your eyes, there is no feeling of sluggishness at all.

    As for the effect, of course, there is nothing to say. Thanks to the advanced technology of infrared components, the system can not only see through complex weather such as clouds, fog, rain, snow, etc., but can also achieve a slight infrared gaze function, thereby further improving vision.  distance.

    According to Ascendas Group¡¯s test on the modified Yun-15plus, under the condition of 250 meters of visibility, the visual enhancement system produced by Ascendas Group can reach a distance of 3,200 meters.

    If the weather conditions are good, the operating distance can further reach more than 6,000 meters.

    This value is almost the same as similar products produced by American and French manufacturers, and is enough to reach the world's advanced level.

    The reason why it has not become the world leader is mainly because Ascendas Group¡¯s visual augmentation system has obvious shortcomings compared with products from the United States and France. The most critical one is that the entire system is relatively large in size and weight.

    Products from the United States and France are only the size of a shoe box and weigh only a few kilograms. However, Ascendas Group's products are larger than an ordinary black and white TV and weigh close to 20 kilograms.

    There is no way, Ascendas Group cannot buy too advanced components, and cannot produce them domestically. Ascendas Group engineers can only use components with average performance for integration. System integration and industrial design are naturally inferior to those in the United States and the United States.  French product.

    But it would be a mistake to judge Ascendas Group¡¯s products based on this. Although this system is not compact enough, with the addition of the display system specially developed by Ascendas Group, the advantages of the entire product will be highlighted.

    Because the display system used by Ascendas Group is not a simple display screen, nor is it an LCD screen that has just started, but specializes in optical diffraction screens on aviation aircraft.

    It is as transparent as window glass, but can display various flight data and parameters of the aircraft after startup.

    ???????????????????????????????????????????????????????????????????????????????????????????mbmbgs Out Outlet This technology was originally applied to fighter jets, allowing pilots to reduce the huge burden during takeoff and landing of aircraft and ever-changing air battles, thus becoming a crucial display equipment in the history of aviation.

    Because of this, optical diffraction screens have become an important equipment that countries around the world are vying to equip.

    It¡¯s just that for a long time, this type of product has been exclusive to military aircraft. Due to factors such as cost and technical barriers, it is not commonly used by civilian aircraft.

    However, in order to open up the international regional passenger aircraft market as soon as possible, Ascendas Group has been increasing the technical level of the Taidong Qing series regional passenger aircraft, one of which is the installation of optical diffraction screens.

    It¡¯s just that Tengfei Group has no technology accumulation in this area, and even its subsidiary North China Optical Research Institute has no clue about this. After all, this technology involves more advanced optical technology and processing capabilities.

    Fortunately, Ascendas Group has applied this technology in another important supporting project it participated in.

    So Ascendas Group immediately started cooperation with another participant to develop a special optical diffraction head-up display for the Coastline regional airliner.

    And this important project is none other than the 10.?Engineering.

    The detection equipment is available, and the display equipment is also solved. The combination of the two is the visual augmentation system on the Yun-15plus. When flying at night, there is no need for pilots to stare at the screen on the instrument stand all the time like American and French products.  Instead, you can put down the optical diffraction screen and just look ahead as usual when flying, because the optical diffraction screen can project the detected infrared signal image onto the diffraction screen, allowing the pilot to take off and land the aircraft at night.  It's as safe and relaxing as daylight.

    Of course, the visual augmentation system is only one of the subjects of allowing the five Y-15plus to land safely on the shooting range island to complete the island landing exercise.

    After all, this island landing exercise is more of a military test and verification, not a real drill for soldiers with live ammunition. Because of this, the five Y-15plus did not carry a full load of airborne soldiers.  Of course, even if there are soldiers, the airborne troops cannot intervene, because the next subject is airspace defense.

    That is to gain air superiority over the occupied island and maintain this advantage for at least 72 hours.

    This subject may not be a big deal inland, but at sea, the pressure faced by domestic aviation forces is not as great as usual. So when everything on the shooting range island was settled, the white fish belly on the horizon gradually emerged. At this time  The voice of the commander of the Su-27 fleet cruising over the island rang on the air-ground radio next to Zheng Quanli: "Our mission is about to end. The new comrades will hold up the sky shield for you. I wish you good luck.  goodbye!"

    As soon as he finished speaking, a Su-27 roared past the island at low altitude, and immediately flapped its wings and dived into the thick clouds.

    Zheng Quanli held up the communicator and looked at the disappearing Su-27. He wanted to say something, but he didn't know how to say it as soon as it came to his mouth. In the end, he could only turn into two words: "Goodbye!"

    After saying that, he put down the phone and looked at Wen Kai who was eating compressed biscuits: "Now it's time to test Lao Xue."

    As soon as these words were spoken, the sky roared again, and the next moment the slender figures of the two J-82 fighter jets came into people's eyes accompanied by the morning glow
