Toni ::Testiraju winglete
http://www.eglin.af.mil/news/story.asp?id=123472548
Wingleti bi trebalo da smanje potrosnju za 3 %
Citat:
Three percent might seem like a paltry amount, but for the sprawling Air Force, every gallon saved adds up big. The flying branch inevitably spends billions of dollars per year to gas up its aircraft, give or take some variation due to fluctuating global prices.
H-model C-130 Hercules transport planes can hold up to 60,000 pounds of fuel. During the 2015 fiscal year, the Air Force’s entire fleet of the standard four-engine planes flew more than 180,000 hours.
Four years ago, the service spent around $10 billion on fuel, according to a report by Air Force Magazine. Arguably, the key to U.S. military hegemony is logistics — and in logistics, cost rules everything. If the Air Force could cut fuel consumption by three percent across the board, that could free up some $300 million in extra cash.
So, while the flying branch began testing a new five-foot winglet on a special purpose MC-130, Lockheed has proposed fitting its fuel-efficiency winglets to all C-130s.
But that’s probably a long way off.

 Citat:This C-130B Hercules was modified off the assembly line in Marietta, Georgia, as a prototype for a Short Takeoff and Landing transport for the US Army. This aircraft (Air Force serial number 58-0712) was fitted with a boundary layer air control system that consisted of a wider rudder, single-hinged flaps instead of the standard Fowler flaps, and two Allison YT56-A-6 jet engines under the outer wings. Bleed air from the jets was blown over the flaps and rudder to enhance lift and controllability. First flown on 8 February 1960, this testbed was flown for twenty-three hours before the Army lost interest in what was to be designated the C-130C. The aircraft later served as a NASA research aircraft. Citat:In November 1963—fifty years ago—the US Navy tested the feasibility of operating a KC-130 tanker off the deck of an aircraft carrier as a way to deliver oversize payloads such as a J79 jet engine. Navy test pilot Lt. James Flatley, copilot Lt. Cmdr. W. W. “Smokey” Stovall, and flight engineers ADR-1 Ed Brennan and ADR-1 Al Sieve made twenty-one full stop landings on the USS Forrestal (CVA-59) without an arresting hook on three flights from NAS Patuxent River, Maryland. The KC-130F, which was retired to the National Museum of Naval Aviation at NAS Pensacola, Florida, in 2005, had “Look Ma, No Hook” painted under the copilot’s windows. The KC-130F carrier trials were kept secret for a year.

Poleteo prvi izraelski modernizovani C-130H
Citat:
The test demonstrated “out of the window” flight, in which live video was displayed on the head-up display (HUD), presenting flight and navigation data overlaying the real world by using two and three dimensional symbols, enhanced degraded visual landing applications and head tracking capabilities. Airborne refueling was also demonstrated as part of the flight tests.
The IAF pilots were impressed with the new capabilities, and the feedback was positive. They emphasised the contribution to flight safety of the new configuration and the enhanced situational awareness gained in different phases of the flight. They also noted the reduced workload and the improved cockpit communication due to flight in “head out” orientation.
The modernisation project, which began in 2012, extends the operational life of the aircraft and significantly improves its operational capability, particularly in precision flying, low-level night flight and operations in adverse weather. The modernisation not only contributes to improved flight safety but also reduces operating costs by introducing cutting-edge digital systems to replace obsolete analog systems that have become unreliable and costly to maintain after four decades of intensive service.
