With the advent of the hypersonic era, diverse combat methods of hypersonic precision-guided weapons have been gradually developed. This study focuses on the precise design of a conformal infrared dome to accommodate different working conditions. To achieve this, an adaptive optimization technology for configuring conformal infrared domes is proposed, employing a multi-objective genetic algorithm. The technology enables the dome to dynamically balance its aerodynamic and imaging performance, taking into account the specific characteristics of each working condition. Moreover, it streamlines the design process of the conformal infrared domes. By optimizing the design with von Karman surfaces, we can overcome the limitations associated with the traditional quadric configuration. In order to evaluate its performance, a comparison was made with a conventional ellipsoid dome. The results indicate that, under the same working conditions, the air drag coefficient of the optimized infrared dome is reduced by 34.29% and that the peak signal-to-noise ratio of the distorted image from the infrared detection system is increased by 1.7%. We have demonstrated the effectiveness of the optimization method to balance aerodynamic performance and optical performance. Hopefully, our new method will improve the comprehensive performance of the infrared dome as well as the guidance capability of infrared detection technology.
随着高超声速时代的到来，高超声速精确制导武器的多种作战方式逐渐得到发展。本研究聚焦于共形红外整流罩的精确设计，以适应不同的工作条件。为此，提出了一种采用多目标遗传算法的共形红外整流罩配置自适应优化技术。该技术使整流罩能够根据每个工作条件的具体特性，动态平衡其空气动力学性能和成像性能。此外，它简化了共形红外整流罩的设计过程。通过用冯·卡门曲面优化设计，我们可以克服传统二次曲面构型的局限性。为了评估其性能，与传统椭球整流罩进行了比较。结果表明，在相同工作条件下，优化后的红外整流罩空气阻力系数降低了34.29%，红外探测系统失真图像的峰值信噪比提高了1.7%。我们已经证明了该优化方法在平衡空气动力学性能和光学性能方面的有效性。有望我们的新方法将提高红外整流罩的综合性能以及红外探测技术的制导能力。
