Open the CIPO recordAbstract From the Canadian patent
A dual-flow jet turbine engine thrust reverser has pivoting doors (7) which are integral with the outer wall of the pod in forward thrust and which constitute obstacles deflecting the efflux in reverse thrust after being pivoted by an actuator (8). Each door (7) is fitted with at least one deflector vane (22) of wing-shaped aerodynamic profile positioned in contact with the efflux in the annular duct (21) in a manner such that the efflux acts on the said vane (22) so as to keep the door (7) in the closed position in forward thrust.

Why it's free to use
- Filed May 6, 1997 and granted September 30, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 6, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 6, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
