由于它们的低空姿态和相对低速作战剖面，直升飞机受到来自无线电、红外（IR）、视觉和听觉探测和跟踪的严重威胁。在这些威胁中，红外探测和跟踪被认为对直升机的生存能力更为关键。为了满足直升机红外隐身的要求，研制了几种不同类型的直升机红外抑制器。本文综述了该学科的最新发展，特别强调了红外特征抑制，混合喷射器和直升机预测的进展。此外，提出了先进IRS、发射率优化技术、直升机红外表征等仍存在的挑战，为未来的研究提供初步指导和激励。未来，3-5 μm波段和8-14 μm波段的红外综合抑制无疑将成为直升机隐身的重点。一个完整的红外抑制系统的多学科优化值得进一步研究。
Due to their low-attitude and relatively low-speed fight profiles, helicopters are subjected to serious threats from radio, infrared (IR), visual, and aural detection and tracking. Among these threats, infrared detection and tracking are regarded as more crucial for the survivability of helicopters. In order to meet the requirements of infrared stealth, several different types of infrared suppressor (IRS) for helicopters have been developed. This paper reviews contemporary developments in this discipline, with particular emphasis on infrared signature suppression, advances in mixer-ejectors and prediction for helicopters. In addition, several remaining challenges, such as advanced IRS, emissivity optimization technique, helicopter infrared characterization, etc., are proposed, as an initial guide and stimulation for future research. In the future, the comprehensive infrared suppression in the 3–5 μm and 8–14 μm bands will doubtfully become the emphasis of helicopter stealth. Multidisciplinary optimization of a complete infrared suppression system deserves further investigation.
