After the large-length air inlet is welded to the main structure of the warhead, it is equivalent to adding four very strong stiffeners to the entire middle and rear parts, and the structural performance of the entire missile body has been improved at a small weight cost. Aerodynamically speaking, the rectangular air intake itself will play the role of a part of the wing, which can generate lift in flight like an airplane wing. Due to the large length of the air inlet and the high flight speed, the lift gain from the rectangular air intake is very considerable, which has a very large impact on the reduction of fuel consumption over the entire range of the missile. In addition, the air intake of the CM-302 also has a bevel angle, which is equivalent to an inclined plane that extends forward from the air intake, and the air hits this inclined plane and begins to decelerate and pressurize, so as to improve the efficiency of the air intake.
After receiving the first confirmation of the target parameters of the early warning radar of its own side through the data link, and after the guidance system sends the parameters to the flight control system, the missile begins to descend to the flight altitude and enters the low-altitude cruise state. At the low-altitude cruising stage, the missile flies silently with the guidance of satellite navigation and inertial navigation at a speed of 1Mach 5, height 12, 15 meters. When the flight is 50 kilometers away from the attack target, the active guidance radar is turned on and confirms the latest parameters of the target with satellite guidance, and then compares it with the data link information, and the missile enters the terminal attack state after confirmation. It is reported that the diameter of CM-302 may be 0It is about 5 meters and has a length of about 63 meters, the maximum effective range is 290 kilometers. However, this maximum effective range is obtained when using a high-altitude trajectory, and if a low-altitude trajectory is used, the range will be reduced to a certain extent.
