Armstrong Siddeley Viper ASV.8
Historical Armstrong Siddeley Viper ASV.8 turbojet model used as the original two-engine powerplant of the Bell X-14 vectored-thrust VTOL research aircraft. The engine exhaust was redirected through cascade diverters for vertical lift; the X-14 installation also bled compressor air for reaction controls.
