[LMTAS photo]Flight testing with aerodynamic shapes was conducted on an F-16C at Eglin Air Force Base, Fla., from March through August. A total of 24 test flights and 65 flight test hours were accomplished, and testing involved loads, flutter, and stability and control.Lockheed Martin puts a lot of effort to it in response to international market demands for more range and payload. CFTs have become a very popular option in recent orders and new business pursuits.Lockheed Martin began F-16 flight demonstration of an initial CFT shape in 1994 to investigate performance and handling quality characteristics. Subsequent wind tunnel testing led to the current external lines, which were initially validated in flight testing of high angle-of-attack handling characteristics at Edwards AFB, Calif., last year."The flying qualities of the F-16 with CFTs are essentially unchanged when compared to a non-CFT equipped airplane," said Stephen W. Barter, chief F-16 test pilot and company CFT project pilot. "For most combat flight conditions, it's as if the CFTs are not even there. The surest way for me to tell if CFTs are installed is to look over my shoulder.""The CFTs have very little adverse affect on the F-16's renowned performance," said Maj. Timothy S. McDonald, U.S. Air Force project pilot for CFT testing at Eglin. "The aircraft retains its full 9-g capability and flight envelope with the CFTs installed. The drag impact is very small - less than one percent in combat configuration at cruise conditions."[URL unfurl="true"]https://www.f-16.net/f-16-news-article781.html[/URL]Cita:Block 52/60 F-16 aircraft, currently procured for Israel, Greece and the UAE, have structural, plumbing, and wiring provisions for the Conformal Fuel Tanks (CFT). These external, pod-like fuel reservoirs are attached on the upper surface of the F-16’s fuselage, with the tank’s lower surface conforming to the aircraft shape. The upper surface arrangement allows the CFTs to be relatively light weight because nothing is suspended from them. With an empty weight of 900 pounds, tank set holds 450 gallons (ca. 3,050 pounds, or 2,271 litres) of additional JP-5/8 fuel.[URL unfurl="true"]https://defense-update.com/20040204_f-16-cft.html[/URL]Está probado en F-16C y homologado desde los Block 50/52 para arriba, requiriendo provisiones estructurales, de cañería y cableado.Saludos</blockquote>
