The F4U-4 Corsair is a single-place, single-engine, low-wing monoplane, and is an advance development of the F4U1 airplane, popularly known as the “Corsair”.  Designed as a land or carrier based fighter, the airplane was manufactured by the Chance Vought Aircraft Division, United Aircraft Corporation, Stratford, Connecticut.  The distinguishing characteristics of the F4U-4 airplane are the inverted gull wing, the nose-cowl-air-inlet, and the four-bladed propeller.

Type of Construction

SRM Fig 126 Exploded View Engine Section.jpg (360656 bytes)Engine Section:  The engine section structure extends from the nose cowl air inlet in the nose of the airplane, to the firewall and is fabricated of welded steel tubing, alclad sheet and stainless steel.  It includes the engine mount, nose cowl, removable cowl panels and cowl flaps.  (Fig 126)  


SRM Fig 124 Main Landing Gear.jpg (566655 bytes)Alighting Group:  The alighting gear unit consists of the main landing gear, located in the center section wing, and the tail wheel gear, attached to the aft fuselage bulkhead at Station 288.  Both units are retractable.  (Fig 124) (Fig 125)


SRM_Fig_13_Center Section copy.jpg (74468 bytes)Wing Group:  The cantilever wing, constructed essentially of metal and fabric, consists of two outer panels hinged to an inverted, gull wing-shaped center section.  The center section of the wing is integral with the fuselage and serves as the support for the landing gear.  Attached to each side of the center section portion of the wing group are two, metal-covered flaps.  A third metal-covered flap and the wood aileron attach to the outer panel portion of the wing group.  (Fig 13)

SRM Fig 104 View of Fuselage.jpg (362443 bytes)Body Group:  The semi-monocoque construction of the aluminum alloy fuselage structure is reinforced in cross section by stiffened bulkheads and frames, and longitudinally by longerons and stiffeners.  The fuselage is assembled in three main sections:  the front section, the mid section and the aft section.  (Fig 104)

SRM_Fig_79_Exploded_Tail_Section.jpg (329447 bytes)Tail Group:  The tail group embodies full cantilever construction, that is, it uses no external bracing whatsoever.  The fixed members of the tail group are made entirely of metal.  The movable surfaces are made of aluminum alloy skeletons and covered with doped fabric. (Fig 79)
