TR On A Newer Citation?

How do the thrust reversers work on the aircraft in the photo?

I know planes like the Gulfstream have them on the top and bottom to form a cup and direct the thrust forward to slow the aircraft down but on this thing there is only one.

Technically these are not thrust reversers, they are called thrust attenuators. They do not reverse the exhaust flow, and therefore are not certified to FAR 23.933. On the 525 (CJ1) and 525A (CJ2) they are hydraulically actuated and they deflect the flow outward. They are hinged at the front of the black attenuator, and the aft portion moves outboard - just like the cabin entry door.

On the newer 525B (CJ3) recently certified, the thrust attenuators were not included in the design for two reasons. One - the CJ3 engine is FADEC controlled and the lower idle thrust settings means slower taxi speeds. Two - the CJ3 being heavier does not coast as far when thrust is at idle.

There aren't any CJ3 photos in the database yet. About 10 have been delivered so far. As a matter of fact Harrison Ford, the actor, picked up 525B S/N 9 last week.

If I'm not mistaken, the TA's can be found on the C650 as well as the CJ's. If you're a friendly corporate pilot, you'll remember to use them to spare us guys at the FBO the jet blast!  hot

C650s have clamshell reversers.

I know the C650s come with your typical clamshells, but if you look below, you can see the TA on the left engine
