Abstract
Technologies are described herein for a drag recovery scheme. In various examples, a recovery engine is placed within a vortex flow of air caused by the impingement of air upon a nacelle of a main engine. The propeller of the recovery engine can use the vortex flow of air to provide additional thrust the aircraft, thus reducing the load on the main engines or providing an increased velocity.
