Douglas DS-312A (Unicraft, Resin)

TYPE: Experimental pusher fighter. Project


POWER PLANT: One Allison V-1710 liquid-cooled engine, rated at 1,100 hp at 30,000ft, driving contra-rotating propellers via extension shaft

PERFORMANCE:  Data not available

COMMENT: Work on this unusual design started in in 1939. In order to keep the fuselage aerodynamically as clean as possible the engine was mounted in the mid-fuselage, driving counter-rotating three bladed pusher propellers via an extension shaft. Another advantage of the buried engine was enough room for heavy cannon armament in the nose. Thus the pilot had an excellent view and a wide field of fire. Although this fighter project was never realized it was the basis for many other pusher-type aircraft e.g. Bell XP-52, Vultee XP-54 Swoose Goose, Curtiss-Wright XP-55 Ascender, Northrop XP-56 Black Bullet, and Douglas XB-42 Mixmaster.
