传 感 器 飞 机 核 心 关 键 技 术 进 展 与 应 用

SensorCraft is an early warning and surveillance and information synthesis aircraft proposed by the Air Force Research Laboratory，with high ceiling and long endurance. It adopts the platform-payload integration technol⁃ ogy，with the dual features of the aircraft and sensor. Coupling of multiple elements between platform and payload means that the overall layout design is different from that of the traditional Intelligence，Surveillance and Reconnais⁃ sance（ISR）vehicle. Flight conditions and performance indexes bring new challenges to the aerodynamic design. Aeroelastic problem of large aspect ratio flexible wing not only worsens flight performance，but also leads to loss of electromagnetic performance of wing conformal antenna. This paper summarizes the technical characteristics of Sen⁃ sorCraft，expounds the development history of the United States SensorCraft system from two aspects of the flight platform and conformal antenna. From the perspective of technical characteristics，key technologies supporting Sen⁃ sorCraft are sorted out，such as integrated layout design，laminar drag reduction，gust alleviation，conformal antenna design，deformation measurement & reconstruction，and electromagnetic performance compensation. Relevant appli⁃ cations are introduced. The development trend of this aircraft is also discussed in terms of the flight ability，stealth abil⁃ ity，perception ability and coordination ability of the aircraft，so as to provide reference for the new ISR aircraft.
