the original contributor says on the engine fan like the harrier on the engine fan is specific to the front nozzles he's not including the exhaust nozzles they are not on the fan he mentions this in the same breath as lift fan which is also ahead of cg and lift engines which on the only other operational vtol yak were ahead of cg ie all arrangements for lift ahead of cg the second part of the sentence refers to what's done with the engine exhaust ie lift behind the cg pegasus similar so he didn't mention we don't need to change that
