This design produced a propulsive jet which was directed and accelerated through a variable rear nozzle.

The 1993 model was powered by a 650cc Rotax engine with dual carburetors and a tuned exhaust pipe, and a variable trim nozzle was added to the jet pump.

Engines intended for extended use with afterburners often have variable nozzles and other details.

The afterburner features a variable converging-diverging nozzle.

June 1985 saw mild exterior changes, with the biggest mechanical change being a variable nozzle for the VG20ET turbocharged engine.

The new power consists of a 2.2-liter four with variable nozzle turbocharging, and the 3-liter Mitsubishi V6 that was in the test car, a black ES model.

Again two ramps can be used to form a variable supersonic nozzle.

In a military combat engine the variable nozzle allows the exhaust to reach supersonic speed.

It forced air into the stainless steel combustion chamber where fuel was sprayed from seven nozzles and ignited to exhaust out the variable rear nozzle.
