Abstract

The paper describes the experimental development and full-scale demonstration of the use of periodic excitation (Active Flow Control or AFC) to reduce the airframe download on hovering tiltrotor aircraft. The initial 2-D wind tunnel experiments on a wing and flap model are described. Based on positive results from these tests, a full span, scaled, powered model of the Bell XV-15 tiltrotor was built and tested and the data used to prepare for full-scale flight test evaluation on the XV-15 aircraft. The powered model results are also described. In parallel with the model tests, a design effort was conducted to build and qualify actuators for the XV-15 flight test and to prepare the aircraft for their installation. The paper details the flight test program that successfully demonstrated the use of AFC as an effective means of reducing hover download.
