| Acoustic radiation of a moving linear array antenna comprised of axial distributed quadrupoles as dependent on the speed of movement is studied. Analytical expressions for the acoustic radiation have been obtained. A mathematical simulation of pressure amplitude angular characteristics versus antenna orientation, its speed, number of antenna elements, and radiation frequency has been carried out. The results obtained may be applied to the interpretation of experimental data related to gas jet acoustics. |
