Wright XRJ47-W-9 ramjet
Wright XRJ47-W-9 is a heavy-duty historical ramjet variant in the XRJ47 family. NACA evaluated it in a Mach 2.75 free-jet facility with Shell UMF and JP-5, comparing combustion performance, fuel-air ratios, airflow, inlet temperatures, pilot-burner ignition, and operating limits. U.S. Air Force history identifies the more powerful XRJ47-W-9 as the intended ramjet for the later XSM-64A Navaho configuration.
