Breda Ba.88 Lince


Looks ain't everything.

From Wikipedia

The Breda Ba.88 Lince (Italian: Lynx) was a ground-attack aircraft used by the Italian Regia Aeronautica during World War II. Its streamlined design and retractable undercarriage were advanced for the time, and after its debut in 1937 the aircraft established several world speed records.[1] However, when military equipment was installed on production examples, problems of instability developed and the aeroplane's general performance deteriorated. Eventually its operational career was cut short, and the remaining Ba.88 airframes were used as fixed installations on airfields to mislead enemy reconnaissance. It represented, perhaps, the most remarkable failure of any operational aircraft to see service in World War II.

The Ba.88 was an all-metal, twin-engine, two-crew, high-speed monoplane, with a high-mounted wing. It employed a "concentric" fuselage design, with a framework of steel tubes and a metallic skin covering which was both streamlined (having a very small fuselage cross-section) and strong. However, this internal load-bearing structure was very complex and of outdated design, as monocoque designs were starting to be developed elsewhere. The internal struts resulted in excessive weight compounded by manufacturing delays. The narrow confines of the fuselage would require the Ba.88 to carry bombs in a semi-external structure, much to the detriment of the aircraft's aerodynamics. The all-metal wings had two longerons, and housed the engine nacelles, undercarriage main elements, and the majority of the 12 self-sealing fuel tanks (the only protective armour in the aircraft), providing a 1,586 L (419 US gal) total capacity. All three undercarriage units were retractable, which was unusual for the time.[3]

The aircraft was powered by two Piaggio P.XI air-cooled radial engines. They were of the same type as used in other projects such as the Re.2000, and drove two three-blade, continuous-speed 3.2 m (10.4 ft) diameter Breda propellers. The engine nacelles also carried the two main undercarriage units. It had a twin tail to provide the dorsal 7.7 mm (0.303 in) Breda-SAFAT machine gun with a better field of fire.
