On November 19, the World Wide Web quoted a report in the US "War Zone" column that the US military has just realized real fighter pilots and AI-driven virtual enemy aircraft. An F-22 fighter pilot wore an augmented reality helmet in the cockpit and had a "dog fight" with a virtual Chinese J-20 fighter. According to
, as the U.S. military strategy shifts to the "superpower competition" between China and Russia, the U.S. military is also focusing on our military's combat equipment and systems for specializing and refining.
Computer simulation training is nothing new. At present, there are computer simulation training in many fields, and the most common application of this technology is the military of various countries. Take our army as an example. At present, there are not only simulation simulators for aircraft training, but also simulation training simulators for tanks and warships. Training troops through training simulators can save hundreds of millions of training costs every year.
To be a good air combat simulator, you must be very familiar with the aircraft to be simulated, at least as close as possible to the level of the simulated aircraft in programming, not too outrageous. If the simulator's parameter settings are too far from the performance of the real enemy aircraft, it will not be able to achieve the effect of normal training, and it may even mislead the pilots, causing unnecessary casualties on the battlefield.
The J-20 fighter is currently the most advanced and most confidential fighter in our country. Even the chief designer of the J-20 may not be able to understand all the technical details of the fighter in detail. The Americans are even less likely to know the J-20 fighter. The full details. In this case, the air combat simulator produced by the American company cannot simulate the J-20 in detail and accurately, but is only the J-20 fighter jet imagined by the Americans. One of the fatal problems of the
flight simulator is that it cannot simulate the inertia and overload of the aircraft in high-speed maneuvering flight conditions. Fighter planes have great inertia when flying at high speeds. Therefore, when flying at high speeds while making various maneuvers, both the aircraft and the pilots will endure high gravitational angular velocity. The scientific name is "overload", which is usually represented by the English letter G. When the pilot is flying with a large overload, the positive overload will cause brain congestion and visual "red vision"; negative overload will cause cerebral ischemia and visual "black vision". Ordinary people can generally withstand 5 to 6G overloads, and specially trained fighter pilots can withstand 9G overloads. However, if the overload is greater, it will cause permanent damage to the human body. Overload flight is an indispensable subject in the training of fighter pilots of various countries. The two states of
will affect the blood supply to the brain, so they will affect the pilot's thinking and judgment ability. At the same time, because it also affects the blood supply to the eyes, it will also affect the pilot's vision. The tactical simulator cannot simulate black vision and red vision under such high-speed operation, nor can it simulate brain ischemia. Therefore, pilots must undergo special training to overcome the impact on themselves in a large overload flight state. Although the simulator can effectively simulate the fighting between fighters, the physical fitness of the pilots still needs to be trained by actually driving the fighters.
From the above analysis, it is not difficult to know: The United States has neither the detailed parameters of the J-20 fighter jets to simulate the training basis of the aircraft, nor can it train mature fighter pilots solely on simulators. Virtual combat is meaningful for actual fighter pilot training, but it is not as large as reported by the media.
