Analysis of APIAN high speed isolated test results - acoustics and aerodynamics

Abstract

The APIAN programme (Advanced Propulsion Integration Aerodynamics and Noise) launched in 1996 under the coordination of AM Airbus follows GEMINI (1990–1993), and GEMINI II and SNAAP (1993–1996) and the huge advances achieved in 10 years show the large effort allowed by the European scientific community since the end of the 80s to understand propeller physics. This paper details the important experimental achievements of the isolated propeller test in the ONERA S1MA transonic facility; preliminary results of the installed S1MA test in ONERA S1MA are also shortly discussed.
