Question hey paul!
it's me again, brandon. i was wondering if you know how the reverse thrusters on the boeing aircraft redirect the flow of exhaust/air, thus making the plane slow down. i understand how reverse on planes like md80's work, i just don't understand how moving part of the engine cowling back makes the direction of airflow change so dramatically.
thanks again,
brandon
Answer Hi Brandon,
There are basically two different types, one is the
clamshell type which is mounted on the outside
of the engine and when deployed it covers the
end of the exhaust and deflects the engine
exhaust forward. The second type is the sleeve
type, they again close over the exhaust of the
engine but their mechanism is contained within
the engine, and the exhaust is directed forward
through grills at the side of the engine pod.
The clamshell type tend to be a bit heavier but
more efficient. They are typically hydraulically
activated and can only be deployed when the
aircraft is on the ground, it has happened in
flight due to a system failure and aircraft have
been lost because of it. On propeller aircraft
reverse is achieved by varying the angle of the
propeller blades to a negative pitch.
