F6F has almost no accidents in its early use. The aircraft has a solid, reliable and durable structure. It is known as the most suitable fighter for young pilots of the U.S. military. According to the battlefield data, the F6F experimental xf6f-3 is converted to the same power unit as the Republic P-47 "thunder" fighter, using the newly designed 2000hp (1500kW) Pratt & Whitney r-2800doublewasp air-cooled radial piston engine, with two-speed two-stage supercharger and water injection. Before the first flight in June 1942, the F6F body was redesigned and strengthened to integrate 2000hp (1500kW) r-2800-10, so as to drive the three blade Hamilton standard propeller, which improved the performance of xf6f-3 by 25% compared with xf6f-1.?A 250 US gallon (950 liter) self sealing fuel tank is installed in the middle of the fuselage, and a 481 gallon (1820 liter) fuel tank is also installed in the main wing and fuselage midline hanger. The total fuel payload is more than twice that of F4F The power parts are also equipped with multi-layer protection, so that the F6F fuel tank is not easy to be attacked in battle, resulting in oil leakage, serious damage and loss of power, which greatly improves the survival probability of damaged aircraft. After improvement, the maximum speed of F6F can reach 629 km / h, the upper limit of flight is 11400 m, the climbing speed is 13 m / s, and the combat range can reach 1521 km and 821 nautical miles.?Simple bodyThe appearance design of F6F is simple and can be drawn directly with a ruler. The large wing adopts a simple geometric trapezoid, and the fuselage and tail are straight lines. The aileron is equipped with spring-loaded control tabs, and the improved windshield has a flat bulletproof glass front panel for better clarity. F6F uses a wide range of hydraulic devices to drive the landing gear strut to rotate 90 ° and retract the wing backward. The brace is equipped with a complete wheel door, which covers the whole brace and the upper ha
