AS22759
This specification covers fluoropolymer-insulated single conductor electrical wires made with tin-coated, silver-coated, or nickel-coated conductors of copper or copper alloy as specified in the applicable specification sheet. The fluoropolymer insulation of these wires may be polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), polyvinylidene fluoride (PVF2), ethylene-tetrafluoroethylene copolymer (ETFE), or other fluoropolymer resin. The fluoropolymer may be used alone or in combination with other insulation materials.

Wing-Lift Augmentation Methods for the Improvement of Low-Speed Performance of High-Speed Aircraft

FOR more than half a century, aeronautical researchers have attempted to augment wing-lift beyond the capabilities of mechanical flaps, slots, and the like. Theoretical studies and wind tunnel tests promised large gains in aircraft performance, but flight installations all over the world proved a long series of failures. Because of the problems inherent in the operation of high-speed jet aircraft, the Department of Defense revived interest in lift-increase systems. A development of the Bureau of Aeronautics recently flight-tested on a Grumman jet fighter demonstrated what is considered the first practical, operationally suitable lift-augmentation system. Under the name of the BuAer Supercirculation System, whereby engine power was successfully diverted to create lift, it has provided new impetus for industry-wide research in the field.

Wind and Temperature Database for Flight Planning

This paper discusses the importance of enroute wind conditions and the need for a wind measurement system which provides accurate and timely observations of wind and temperature conditions aloft. Recent advances in remote measurement of winds, temperature, and humidity such as the Stratospheric-Tropospheric radars and profilers developed at the National Oceanic and Atmospheric Administration’s Environmental Research Lab form the basis of such a system. A domestic system could and should be established using these devices together with a near real time winds aloft data dissemination network. Estimates of the saving in aircraft fuel consumption benefits range from 1 to 3 percent per year, or from $ 100 to $ 300 million for U.S. aviation system users at current prices and consumption.
