Open the CIPO recordAbstract From the Canadian patent
In a control system for a gas turbine aero engine without using the engine inlet sensors the engine inlet condition data including the intake air temperature and the intake air pressure is estimated based at least on the detected rotational speed of the turbine the detected inlet pressure of the turbine and the detected atmospheric pressure etc. through reasoning. Thus, the system can remove the engine inlet sensors (which are generally expensive) and instead enables to estimate the engine inlet condition data necessary for controlling the engine with a relatively simple configuration.

Why it's free to use
- Filed July 28, 2000 and granted November 18, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 28, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 28, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
