First Claim
Patent Images
1. A method for estimating engine thrust, said method comprising:
- obtaining information about an initial dynamic state of the engine; and
updating the information about the initial dynamic state of the engine to reflect a second dynamic state of the engine; and
generating engine thrust estimates, wherein the thrust estimates facilitate implementing direct thrust control.
