Performance Enhancement of a Full-Scale Vertical Tail Model Equipped with Active Flow Control
Abstract
This paper describes wind tunnel test results from a joint NASA/Boeing research effort to advance active flow control (AFC) technology to enhance aerodynamic efficiency. A full-scale Boeing 757 vertical tall model equipped with sweeping jet actuators was tested at the National Full-Scale Aerodynamics Complex (NIFAC) 40- by 80-Foot Wind Tunnel (40x80) at NASA Ames Research Center. The model was tested at a nominal airspeed of 100 knots and across rudder deflections and sideslip angles that covered the vertical tail flight envelope. A successful demonstration or AFC-enhanced vertical tail technology was achieved. A 31-actuator configuration significantly increased side force (by greater than 20%) at a maximum rudder deflection of 30°. The successful demonstration of this application has cleared the way for a flight demonstration on the Boeing 757 ecoDemonstrator in 2015.

This multi-organizational and multidisciplinary teaming effort involved many people who provided valuable contributions through their detailed work and/or expert guidance. The contributors have come from within the NASA/Boeing team and their partners. The NASA/Boeing collaboration was executed through a Space Act Agreement (Annex 8 to SAA1-1155). The NASA ERA project sponsored the sweeping jet AFC technology via Caltech (TEAMS 2 Contract NNL12AA09C) and the University of Arizona (direct subcontract). The ERA project also sponsored the wind tunnel test at NFAC (NIPR# NNL12AA13T). The authors would like to thank key personnel in the following organizations for their excellent support during the course of this investigation: Boeing Commercial Airplanes: Kate Nowicki (technology manager), John Brandt (stability & control), Kyle Ford (loads & dynamics), and Helen Mooney (aerodynamics).Attached Files
