Abstract

An airplane, which includes an airframe and a full-segregated thrust hybrid propulsion system mounted on the airframe. The propulsion system includes: one or more sustainer thrust producers; a plurality of electrically powered thrust producers disposed in predetermined positions as a means for providing additional thrust to the airplane, and to supplement airflow over the wings, flaps, and roll control devices of said airplane; whereby increasing the lift of the wing surfaces and providing enhanced control in the roll axis. The trust producers operate independently from one another, with no aerodynamic, electrical or mechanical inter-connection. Safety is enhanced by the ability of either the sustainer thrust producer(s), or the electrically powered augmentation thrust producers to sustain flight to a suitable landing area, should the other system fail.

Dependent claims

A segregated thrust hybrid propulsion system for airplanes consisting of an airframe and a segregated thrust hybrid propulsion system mounted on the airframe, comprising:

one, or more, sustainer thrust producers capable of supplying the thrust required for the cruise flight regime;
and
a plurality of electrically powered augmentation thrust producers disposed in predetermined positions as a means for providing additional thrust to the airplane, and to supplement airflow over the wings and roll control devices of said airplane during the take-off and climb regime, whereby improving the performance envelope of the airplane and enhancing safety;
said electrical powered augmentation thrust producers comprising:
(a) a chemical storage battery, or other electrical power source;
(b) said electrical power source being connected to a speed control device;
(c) said speed control device being connected to an electric motor;
(d) said electric motor being connected to a propeller.
