According to a partially incomplete description in The Staggerwing Story it was a design
for a very large staggered wing biplane and was conceived in 1941 to Army Air Corps Spec.
R-1800-D. No illustration in book.
Wingspan: 108' 9"
Wing area: 3,410 in sq
Length: not listed
Fuselage width/depth: 16' X 19', description states (16' diameter, oval cross-section?)
Structure: all metal, upper wing in three sections, stainless steel covering from leading edge
to main spar, fabric from spar to trailing edge, lower wing panels hinged at landing gear truss
extensions
Landing gear: conventional, retracted inward into lower fuselage (taildragger?)
Engines: four V-1710 (1,150hp at 3,000 rpm), 4,600hp total, mounted in an engine room
turning a single 23' diameter 4-blade propeller, distance from propeller tip to ground was 7'
(think Linke-Hoffman RII).
Engine room to be fitted with CO2 fire suppression system designed to flood compartment
which then allowed a mask equipped mechanic to enter to effect repairs
Fuel: 3,250 gallons - 1,400 in wing, remainder in fuselage tanks fwd. of main gear
Max range: 4,000 miles
Design gross weight: 61,264 lbs
Max speed: 230 mph (13,000')
Cruise speed: 165 mph (65% power)
Takeoff/anding over 50' obstacle: 1,800'
Ceiling: 22,000' (10,000' on two engines)
Crew: 3
Cargo: 70 fully equipped soldiers, mix of personnel and equipment, or equipment only
Built in power-operated for loading vehicles etc. through a 10' X 15' hatch
Example load: 75mm cannon (1), 75mm ammo (174 rounds), 'reconnaissance cars' (2),
soldiers (4), .30 MGs (2), fuel and oil for vehicles
Has anyone ever seen a drawing or come across more details?
