Augmentable Air Injected Plenum Propulsion Drive for Electric VTOL Operation and Flight

Abstract

Here on Earth, there is a need and is quite essential that we keep moving. But we must be progressive in our living and livelihood while protecting and preserving our planet. There are places to go, people to meet, and business to be had. Designed with electric aircraft and flying cars or taxis in mind, the Augmentable Air Injected Plenum Propulsion Drive for Electric VTOL Operation and Flight is the first electric VTOL propulsion system to employ the concept of opposing air flow and cyclic column compression of those opposing flow(s) to pressurize a plenum chamber. Opposing flow and cyclic column compression is then harnessed for the purpose of augmenting, or amplifying, injected air to provide enhanced air/fluid power to an electric VTOL thrust system for the purpose of VTOL operation and horizontal flight and is multi-modal for VTOL and horizontal flight.

BRIEF SUMMARY OF THE INVENTION

The Augmentable Air Injected Plenum Propulsion Drive for Electric VTOL Operation and Flight, Plenum Propulsion Drive, or PPD for short, is the first eVTOL engine and/or propulsion system to employ the concept of opposing airflow and cyclic column compression of those opposing flow(s) to pressurize a plenum chamber for the purpose of augmenting, or amplifying, injected air to provide enhanced air/fluid power to an electric VTOL thrust system for VTOL operation and flight.

The PPD engine is a synergistic multimode propulsion system that utilizes opposing accelerated airflow to produce compression and augments that compression for vertical takeoff and landing. It then uses the same accelerated and dynamically compressed airflow to produce horizontal flight motion and thrust by transitioning the thrust tube assembly and reversing the fans of the two rear injectors for horizontal flight. The plenum chamber is central to the overall synergistic action. This is called cyclic column compression with a multi-mode application. Cyclic column compression is just a term to describe dynamic compression that takes place in the injectors and then in the plenum chamber. It is through cyclic column compression that columns of air are drawn in by the injectors and compressed. The injectors then pass that air into the plenum chamber and thereby have further dynamic compression of that air. The secondarily compressed air is then shunted to the Ventral VTOL Thrust Assembly for VTOL operation. Coupled with the action of the Thrust Tubes, Thrust Tube Sheaths, and multi-modal transition mechanisms, which will all be referred to as the Thrust Tube Assembly for clarity, the primary compression starts in the injectors and secondary compression is done in the plenum chamber where air is dynamically and continually forced in, accelerated, compressed, and then supplied to the Ventral VTOL Thruster Assembly for VTOL mode of operation. This condition is set until the system requires laminar in-line flow for horizontal flight mode and then transitional elements switch the PPD to horizontal flight mode.
