A unique facility has been developed at the Lockheed-Georgia Company to evaluate, simultaneously, acoustic and propulsion performance characteristics of lift augmentation systems of the type considered for V/STOL aircraft. The facility is ideally suited for concept parametric and systematic noise-reduction investigations where the relationship between farfield acoustics and powered lift propulsion performance is required. The facility comprises an outdoor test rig and a control room. The important features of the test rig include (i) provision of a fully instrumented quiet air supply of up to 20 lb/sec with primary and secondary nozzles, (ii) wing/flap support structures instrumented for measuring aerodynamic loads, and (iii) an arch, carrying a microphone, which can rotate through a hemisphere around the noise source to acoustically map nonaxially symmetric noise fields. The essential features of the control room include (i) remote control of the two airflow pressure ratios, (ii) remote control of the microphone arch location, (iii) data acquisition and reduction capabilities, (iv) on-line display of acoustic and propulsion performance measurements, and (v) central computer access to provide “quick-look” full-scale acoustics. Capabilities are present to make velocity surveys and to measure surface fluctuating pressure levels. Concepts already evaluated include externally blown flap with both lower and upper surface blowing. Applications of this versatile facility include acoustic and propulsion performance studies of (i) a fundamental nature, (ii) powered lift concepts, (iii) single or multiple flow jet noise from various nozzle shapes, and (iv) shielding effect of aircraft structures upon radiated sound.
