Boeing 787-8, Trent 1000, Thrust Reverser operation.

This video shows the operation of the Thrust Reverser on a Trent 1000 powered Boeing 787.

In the video you can see the blocker doors closing the D-Duct (aka the Fan Duct) when the Thrust Reverser section moves rearwards. As it moves rearwards, it opens the sides of the engine, the Fan Air moves out through the sides instead of going out of the back. This directs the thrust of the Fan through the Cascade Vanes on the sides of the Thrust Reverser (seen in the video), the cascade vanes are basically grills that direct the air forwards to aid braking after landing.

That's so awesome to actually see the internals of the reverser. Previously I've only ever seen the sliding cowl

SO THATS HOW IT WORKS, JESUS IVE BEEN SO CONFUSED FOR SO LONG

As someone who 'makes' components for these engines I really enjoy videos such as this one.

Was a pleasure being on Boeing's strategic support team working with these aircraft every day.

Thank you for sharing this video, I always wondered how it actually worked, especially internally.

[MrJazml]

Bring back more videos like this to your channel!

I used to make those kind of blocker doors, real interesting to know how they're built

Saw them doing this test on a 748 in the factory while walking to the 777X line yesterday.

Sweet video! Thanks so much for the great description. I always thought the fan/cold section had a thru path front to back and the reverser blocked off that section-but I see when the door is opened it blocks off the REAR as well as the front(right side of engine in the video) I'd love to see the "target type" clamshells on the CFM airbus engines-but BAW don't have those do they... They're all IAE...

Impressed that they let you film.  GLAD they did. enjoy the video

I'm a mechanical engineer, this is our kind of porn ;)

[TosinSalisu]

@MrIfixplanes your videos are amazing! I bet you love your job so much!

[zbeast]

What is the max thrust setting you can have with the thrust reversers set.

[_Ampersand_]

Awesome needed to see this for a project.

[Helicopterpilot]

Get some video of dry runs up close! That would be sweet! 

[MTAviationPhotoFilm]

Awesome video. Is it Hydraulic or pneumatically actuated?   

[Austinflank]

I noticed the reverser only applies to the bypass air. That's interesting.

[derekwall]

okay now I see how they work the reversers are inside the main fan outlet duct pushing it foward

[plummetplum]

Does thrust reverse just neutralise the remaining thrust from landing. I thinking it can't actually produce more reverse than forward?

[helloworldstein]

Wonder how different the thrust reverser on the GE version of these engines are?
