PROPULSION SYSTEM
First Claim
Patent Images
1. A method of operating a propulsion system comprising:
- propulsing a vehicle by a propulsor powered by an energy storage system;
depleting energy stored in the energy storage system in response to the propulsing;
pulsing on a turbine whereby energy may be provided to the energy storage system;
replenishing, by the turbine, the energy stored in the energy storage system; and
pulsing off the turbine in response to the replenishing; and
replenishing, by the propulsor, the energy stored in the energy storage system by permitting the propulsor to windmill in response to a turbine failure.

Abstract
A propulsion system and related methods are disclosed. A propulsion system may have a propulsor, an energy conversion system, an energy storage system that stores electrical energy, and a turbine. The propulsor may be in electrical communication with the energy conversion system, and the energy conversion system may receive electrical energy from the turbine or the energy storage system and deliver it to the propulsor. In this manner, a vehicle may be propelled by the propulsor even when the turbine is not operating.

4. A propulsion system comprising:
-
a first propulsor; a first energy conversion system; a first energy storage system; and a first turbine, wherein the first propulsor is in electrical communication with the first energy conversion system, and wherein the first energy conversion system receives an energy storage system electrical energy from the first energy storage system and provides a conditioned energy storage system electrical energy to at least one of the first propulsor and an emergency system. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
