QAVION,
Thanks for the info. From what I can tell, and I would think where I am at, that there is a lot of literature on the ADP operation and none of it seems to agree.
The placement of the cooling intake and the exhaust was most probably responsible for you not being able to hear the ADP until you moved. They are designed to reflect away from the cabin.
Testing them this month and next at Paine. Hopefully the functional test guys will know how they are supposed to operate.
