“…[ 4–6 ] In contrast, transparent EMI shielding materials are highly desired for special electronic devices and infrastructures which require transparence in visible and near‐infrared regions, for example, the windows of light‐controlled devices and aircrafts. [ 7 ] In addition, the fast development of wearable electronics also needs flexible EMI shielding materials. [ 6,8 ] Therefore, the exploit of transparent flexible EMI shielding materials attracts much research interest recently.…”

Transparent and flexible electromagnetic interference (EMI) shielding materials are highly desirable in wearable electronic devices and optical windows of aircrafts. Herein, transparent and flexible EMI shielding films are prepared by the use of Cu nanowires (Cu NWs). The films have a sandwiched structure composed of polyethersulfone (PES), Cu NW network, and polyethylene terephthalate (PET). The coating of PES strengthens the Cu NW contact, protects Cu NWs from the oxidation, and reduces the surface average roughness. The PES/Cu NWs/PET sandwich‐structured films show an EMI shielding effectiveness (SE) of 22 dB with an optical transmittance of 73%, and an even higher EMI SE of 30 dB in the entire X band with the optical transmittance of 67%. The PES/Cu NWs/PET sandwich‐structured films also exhibit superior flexibility, very good chemical stability in basic, acidic, and strong oxidizing solutions, as well as long‐term stability in ambient condition. This PES/Cu NWs/PET sandwich‐structured films are a promising transparent flexible EMI shielding material in wearable electronics and optical windows of aircrafts.

“…For the influence of flow control on the separation characteristics of the store, the research of Guo et al [32] indicated that the cylindrical spoiler and leading edge blowing are conducive to the safe separation of the internal bay with the Ma = 3.5. To improve the separation characteristics of the internal store, Song et al [33,34] installed a cuboid control device at the leading edge of the internal bay.…”

To understand the influence of the initial release conditions on the separation characteristics of the store and improve it under high Mach number (Ma = 4) flight conditions, the overset grid method and the Realizable k − ε turbulence model coupled with an equation with six degrees of freedom are used to simulate the store released from the internal bay. The motion trajectory and the attitude angle of the store separation under the conditions of different centroid, velocity, height and control measures are given by the calculated result. Through analysis, the position of the centroid will affect the separation of the store, which needs to be considered in the design. Increasing the launching height is conducive to the separation of the store. If the store has an initial velocity, it can leave the internal bay more quickly and reduce the probability of collision with the wall. Cylindrical rod and slanted aft wall control measures can improve the attitude of the store and make the store fall more smoothly.
