Hi everyone,
I think this would be great add-on to IL-2 1946 for 'what if' 1930s and early part of WW I.
I quote the information from book called "Secret Projects - Flying Wings and Tailess Aircraft by Bill Rose, on page 70.
Under chapter title - US Flying Wings (1935 - 1950)
None of these Boeing flying wing studies progressed much further than the drawing board and they remained unknown until relatively recently. Aside from a long-range bomber, there was a flying boat, an airliner and two variations of a compact one-man fighter with all receiving the in-house umbrella designation Model 306. The long range bomber was completely tailless with swept wings and an unusual system of external elevation supported behind the trailing edge by long struts. Engineers believed this unusual system would be more efficient than normal control surfaces as it avoided any interference with the wing's aerofoil profile. It almost goes without saying that the idea was wind tunnel tested.
AND
The Model 306 flying wing bomber was to be manned by a crew of 10. The wingspan was provisionally set at 140ft (42.6m) and the aircraft's length was 60ft (18.2m). Propulsion took the form of four forward-mounted propellers, each driven by an Allison V-171 0 12 cylinder liquid-cooled engine, producing 850hp (633kW). A fully retractable undercarriage was envisaged with the aircraft's rear section resting on a tail wheel. The bomber would have a range of 5,000 miles (8,000 km) and carry a 2,500 Ib (1,133kg) bomb load with defensive armament consisting of two .50 cal (I 2.7mm) and two .30 cal (7.62mm) machine guns. Had this aircraft progressed towards production, it seems certain that more guns would have been added. Weights, maximum speed and ceiling are unknown, but slightly
better performance than the XB-15 was undoubtedly anticipated.
