The General Aviation XFA-1 was an American biplane fighter aircraft was built for U.S. Navy Specification No. 96, calling for a carrier-based light fighter. This specification was eventually revealed as a cover for the Navy's actual desire for an airship fighter, the Curtiss XF9C-. The XFA was a single-bay biplane with an all-metal fuselage and metal laminate skin. The construction of its fuselage was innovative in that instead of using lap jointing, the edges of each panel were bent inwards, with the rivets fastening them on the inside, instead of being visible on the surface. It had a gull-type upper wing which was fabric covered. The prototype was ordered in 1930, but the company was engaged in an reorganization, which delayed its work. Delivered for evaluations in 1932, it showed poor flying characteristics, including longitudinal instability and over-sensitive controls. General Aircraft increased the area of the tail surfaces and made other changes, then returned the prototype for more testing; but now the stability problems were worse. The plane would nose up with more throttle, but then drop its nose when the throttle was reduced. After another round of modifications, and some close calls, the plane was finally classed as unsafe and testing was abandoned. |
Die General Aviation XFA-1 war ein amerikanischer Doppeldecker-Jäger und wurde für die U.S. Navy Spezifikation No. 96 gebaut die einen leichten Trägergestützten Jäger verlangte. Diese Spezifikation war die verdeckte Ausschreibung für einen Luftschiffjäger welcher später die Curtiss XF9C- wurde Die XFA war ein einfach abgestrebter Doppeldecker mit einem Ganzmetallrumpf. Der Bau des Rumpfes war innovativ, die Kanten jeder Rumpfplatte wurden nach innen gebogen und innen vernietet, so war auf der Außenseite keine Niete sichtbar. Der oberer Flügel hatte einen Knick zum Rumpf und war mit Stoff bespannt. Der Prototyp wurde im Jahr 1930 bestellt, aber die Firma war in einer Umstrukturierung, so verzögerte sich die Arbeit. Die Auslieferung für Flugtests fand 1932 statt und zeigte eine Instabilität um die Längsachse und überempfindliche Steuerelemente. General Aviation vergrößerte das Leitwerk und machte weitere Änderungen. Doch die Stabilitäts-probleme waren nut weitaus schlimmer. Das Flugzeug zog nach oben beim Beschleunigen und mit weniger Leistung fiel die Nase nach unten. Nach einer weiteren Runde von Modifikationen und einigen fast Unfällen wurde das Flugzeug für unsicher erklärt und die Tests abgebrochen. |
