Conference paper


At the present time, ground based test facilities are unable to provide data for the full range of scramjet flight conditions. However, an opportunity exists in which the hardware for the RHYFL shock tunnel could be utilized to create a large expansion tube, RHYFL-X. This paper is part of a continuing project to investigate the use of RHYFL-X as a scramjet test facility. The long term aim of this project is to further validate the previous numerical studies and the claims that the attachment of a nozzle onto an expansion tube will not only increase the core flow diameter but also increase the steady time available for testing. This present paper reviews the literature available for expansion tunnels and presents potential operating conditions for the X2 expansion tube with its new single stage driver.
