This thesis aims at the aerodynamic investigation of plenum chamber type side intake configurations for light weight utility helicopters. A full-scale engine intake wind tunnel setup was designed to achieve realistic flight Mach and Reynolds numbers. To simulate inflight engine mass flow rates, a fan and a Venturi meter are connected to the intake duct. Applying five-hole probe, particle image velocimetry and surface pressure measurements, main characteristics of forward- and sideward facing side intakes are analyzed. Numerical parameter studies complement the experimental results.
