Strategic Study of CAE 2000, Volume 2, Issue 6, Pages 40-48
The bowed-twisted blades have been widely used in the developed countries in the 1990s, such as the USA and UK. In China, this new type blades are also successfully applied to the steam turbines, and the application of these blades to gas turbines of air-engines has had a good beginning. The effectiveness of applying the bowed-twisted blades to turbines demonstrated by the tunnel and static experiments is discussed, and the mechanism of reducing the radial-and cross-secondary flow losses by using the bowed-twisted blades is analyzed in this paper. The advances in research on compressor bowed blades and key problems in this research are considered shortly. Based on design experiences, several principles for designing stages with bowed-twisted blades are summarized in the end of this paper.

Strategic Study of CAE 2006, Volume 8, Issue 11, Pages 74-79
Transmitting effects of aero-optics is very important to optical imaging probing system of interceptor, as it may cause displacement, jitter and blurring of image to receive for the system. The optic transmitting characteristics is analyzed when target ray goes though turbulence flow. The engineering model for optical transmitting characteristics of flow is built up and empirical model for optical imaging system induced by aero-optic transmitting effects is described. The displacement, jitter and blurring are simulated. The numerical simulation results suggest that transmitting effect of aero-optics has powerful influence on the imaging probing system, which is related to flight parameters, imaging system parameters and integration periods of imaging probing system, etc.

In this article, an omnidirectional dual-polarized antenna with synergetic electromagnetic and aerodynamic properties is propounded for high-speed diversity systems. The propounded antenna comprises a probe-fed cavity for horizontally polarized radiation and a microstrip-fed slot for vertical polarization. Double-layer metasurfaces are properly designed as artificial magnetic conductor boundaries with direct metal-mountable onboard installation and compact sizes. An attached wedge-shaped block is utilized for windage reduction in hydrodynamics. The propounded antenna is fabricated for design verification, and the experimental results agree well with the simulated ones. For vertical polarization, the operating bandwidth is in the range of 2.37–2.55 GHz, and the realized gain variation in the azimuthal radiation pattern is 3.67 decibels (dB). While an impedance bandwidth in the range of 2.45–2.47 GHz and a gain variation of 3.71 dB are also achieved for horizontal polarization. A port isolation more than 33 dB is obtained in a compact volume of 0.247λ0 × 0.345λ0 × 0.074λ0, where λ0 represents the wavelength in vacuum at the center frequency, wherein the wedge-shaped block is included. The propounded diversity antenna has electromagnetic and aerodynamic merits, and exhibits an excellent potential for high-speed onboard communication.
