Abstract

The article analyzes technical capabilities of a single rotor dynamic siren with a three-corned modulation function for the formation of the desired range of aerodynamic noise of audio frequency on the stationary stand of ground test systems during the full-scale tests of devices of command-measuring support of aircraft of various types and of location means.

The article considers three options of the technical implementation of the siren rotor: with the radial three-corned windows - the number of seats is 18, the number of seats is 276, the number of seats is 1528. The first option generates a multi-band spectrum of the siren, two others generate spectra with the prevailing saturation of high frequencies.

The results can be used to produce aerodynamic noise generators of ground test systems of hypersonic aircraft.

The suggested technical implementation of the single-rotor siren extends the possibilities of the rotor modification and provides the conditions to select the desired range of acoustic radiation, brought as close as possible to the realities of hypersonic aircraft
