Flight Testing of Pneumatic Forebody Vortex Control on the X-29 Technology Demonstrator 922008

The US Air Force's X-29 Experimental aircraft was used to demonstrate a Wright Laboratory initiative, the Vortex Flow Control (VFC) program. This program involved manipulation of forebody vortices through the use of nitrogen blown from small nose mounted nozzles. A VFC flight test program was recently completed at Edwards AFB CA. Sixty flights were flown between May-August 92 as part of this program, which involved the Air Force's Wright Laboratory and Flight Test Center, NASA, and Grumman Aircraft Systems Division. This paper presents the results of this initiative.
