The venue was so quiet that the pin drop could be heard, everyone held their breath, everyone was shocked, can the winger still be invisible? Of course, at this time, radar has only just appeared, and has not really been used in the military, the emergence of radar is due to the fact that during the First World War, when Britain and Germany were at war, Britain urgently needed a radar (technology) that could detect metal objects in the air to help search for German aircraft in anti-air raid warfare. In 1925, in cooperation with Du Wu, Burrett successfully used radar for the first time, displaying short radio pulses reflected from the ionosphere on cathode ray tubes.

Xiao Weiguo paused, and then continued: "What are we emphasizing the stealth of this radar for? It is important to know that with the rapid development of radar technology, future air operations will have to face the detection of the enemy's radar, and only by not being discovered by the enemy's radar will there be a higher probability of survival. Therefore, when our long-range bombers carry out long-range bombing missions, it is very likely that there is no fighter escort, so in this case, radar stealth performance is particularly important. ”

"Our flying-wing long-range bomber must have sufficiently advanced performance to maintain a leading technological level for a long time. The bomber adopts a wing-body integrated design, 2 wind and thunder turboprop engines are mounted on both sides of the cockpit on the back, the propeller pushes the aircraft forward from behind, and the cockpit adopts a large-angle porthole design to accommodate 5 crew members. Two large magazines are located behind the cockpit, each with a length of 3 meters, a width of 2.5 meters, a depth of 1.5 meters, a normal bomb load of 3,000 kg, a maximum bomb load of up to 4,000 kg, and most importantly, a giant bomb weighing up to 1,000 kg. ”

Xiao Weiguo knew that at this time, the United States was already developing a long-range bomber, that is, the famous B17 four-engine heavy bomber in the history of World War II. Therefore, this kind of flying wing bomber of the Dragon Soul Ordnance Complex will definitely become a heavy bomber that far surpasses the B17 bomber. The origins of the B-17 "Flying Fortress" can be traced all the way back to February 1934, when the U.S. Army Air Corps proposed a tender for the design of a bomber capable of carrying 2,000 kg of bombs and flying 8,045 kilometers at a speed of 322 kilometers per hour. This is an ambitious plan, and the new bomber will be able to cross the two oceans of the United States, east and west. The tender, known as "Plan A," focuses on feasibility studies, but if the design proves successful, the military orders a production prototype. The later B17 bomber, of course, did not have such a long range, it simply reached a range of more than four thousand kilometers. The bomb load is four tons.

Messerschmidt laughed and said: "Then our flying wing bomber can be called a ghost bomber, which is completely capable of going deep into the enemy's sky unconsciously and carrying out horizontal carpet bombing." ”

Xiao Weiguo nodded and said, "Dr. Willy's name for our flying wing bomber is very good, I think I will name it Ghost." This is very much in line with its characteristics. Among the most important indicators of the bomber, whether it is bomb load and range, it is the top, because the high lift-to-drag ratio of the flying wing layout greatly reduces the aerodynamic drag for it, and the flying wing structure is more conducive to the layout of the bomb bay. So it is entirely possible to carry a thousand kilograms of bombs, and even one and a half thousand kilograms is no problem. In bombing, the bomb weighs as much as it gets, and the bombshell is capable of destroying underground targets. ”

"Yes, and our Thunder turboprop engine, which gives it a lot of power, and it doesn't have a high fuel consumption compared to a piston engine, which allows it to fly higher and farther," Messerschmidt said. ”

Xiao Weiguo nodded and said, "This is just the first stage of the development of flying-wing aircraft. After the successful development of our turbofan engine, we can also develop larger flying wing aircraft. For example, a giant bomber weighing 100 tons can also be built. At that time, the range of this giant flying wing aircraft will likely reach tens of thousands of kilometers, and at that time, the flying wing bomber will be the real heavy weapon of a great power! Moreover, we can also develop a flying-wing transport aircraft on the basis of the flying wing aircraft, which has many advantages that the conventional layout transport aircraft does not have. It is also the direction of development of future transport aircraft. Therefore, our designers must do more research and make breakthroughs in the aerodynamic and structural theory of flying wing aircraft. ”

Messerschmidt was pleasantly surprised: "The winger is still so promising, it seems that we all underestimated it before." Just, our flying wing bombers. It is only possible to carry out horizontal bombing, and how to ensure the accuracy of bombing at an altitude of 10,000 meters is a very thorny problem. ”

As soon as Messerschmidt raised this question, everyone except Xiao Wei suddenly became silent. It is true that the problems of the flying wing aircraft themselves may be solved, but the problem of the accuracy of high-altitude horizontal bombing is not easy to solve. Not up to the bombing accuracy specified by the German Ministry of Defense, it is possible that it will be eliminated by competitors, even if it is very advanced in performance.

The bombers of the 30s had only simple mechanical and optical sighting equipment, and the accuracy of bomb delivery depended entirely on the experience and luck of the bombardier. Obviously, the accuracy of the bombers at this time was very low, and even for area bombing where the accuracy requirements were not very high, the effect was not satisfactory.

Seeing that everyone was hit, Xiao Weiguo laughed and said, "Don't be discouraged, everyone!" Our competitors are equally difficult to solve the problem of bombing accuracy. We're all on the same starting line. I had an idea to develop a gyro-stabilized semi-automatic optical sight that could measure the angle of advance. It includes an optical observation device, an observation line stabilization device, a direction sighting device, and a distance sighting device, among others. The optical observation device is used to observe the target, and determine the relative position of the carrier aircraft and the target according to the observation angle, that is, the angle between the observation line and the ground vertical line. The observation line, that is, the connection line from the carrier aircraft to the target, uses the observation line stabilizer to stabilize the starting observation line to prevent errors caused by aircraft pitch and tilt, and ensure the accuracy of the observation angle. The directional sighting device determines and corrects the yaw rate of the aircraft. The distance sighting device calculates the aiming angle, determines the timing of the bomb, and can drop the bomb when the observation angle is equal to the aiming angle. The sight can be designed as two gyroscopic stabilization systems, and the aiming time is long, so that the accuracy of the bombing can be greatly improved. Suffice it to say, I believe that a ghost bomber with such a sight can drop a bomb into a circle with a radius of 30 meters at an altitude of 10,000 meters. ”

Hearing Xiao Weiguo say this, everyone looked at him in unison, because they didn't expect Xiao Weiguo to have such a clever method, especially the two Horton brothers, they had already regarded Xiao Weiguo as an idol, and now Xiao Weiguo has become a god-like person in their minds.
