Does this use of Coanda help the aircraft during cruise phase? Are there other propeller aircraft (like the A400M, ATR, Q400, and Saab 340/2000) that apply the Coanda effect in the same way?
Wikipedia wrote:An innovative use of the "propwash" generated by propellers directed over the full-span flaps led to an impressive minimum speed of 39 mph (63 km/h) which would have allowed the Fleet Shadower to cruise effortlessly above an enemy fleet.
