The present paper aims to provide a summary report on recent research progress about
unstart mechanism, detection and control of hypersonic inlet to help the researchers working …

A review of recent research outcomes in downstream flow choking-driven unstart is
presented. Unstart is a flow phenomenon at the inlet that severely reduces the air mass flow …

An experimental study was conducted to investigate the effects of ramp-type vortex
generators in a Wheeler doublet configuration, vortex generator jets, and their combination …

Large-eddy simulations of stable and unstable ramjet operational modes are presented for
an axisymmetric inlet-isolator-combustor configuration experimentally tested in the …

Shock trains in rectangular isolators with inflow Mach number of 2.5 and ARs of 3.0 and 6.0
are investigated. Knowledge gained is used to propose a rectangular isolator modification to …

To prevent scramjet inlet unstart, stringent control over the shock train's leading edge in the
isolator is necessary. Therefore, this study proposes a fuel flow active control scheme …

Localized arc filament plasma actuators were used to control pressure fluctuations in a
cavity with a depth of 12.7 mm and length-to-depth ratio of 4.86. The rear wall of the cavity is …

The phenomenology of unstart in a dual-mode ethylene-fueled scramjet is studied in the
presence of inflow distortion using carefully calibrated unsteady Reynolds-averaged Navier …

This study demonstrates the closed-loop control of a shock-train location in the isolator of a
Mach 2.2 direct-connect dual-mode scramjet facility (US Air Force Research Laboratory …

Schlieren images and unsteady pressure measurements were collected to explore the
response of a shock train to a high-frequency fluctuating backpressure in an isolator. High …
