Afterburning Turboprops.

The conventional installation of an afterburner involves pairing the afterburner with a jet engine. In this invention, the afterburner is connected to a turboprop engine. 

Collective Afterburners.

An afterburning combustion chamber, usually called an 'afterburner', is usually installed on the exhaust duct of a jet engine. In this invention, a duct is used to channel air and exhaust  flow from two or more engines to a single afterburner. As many as four engines can pump air or exhaust into the same afterburner.
