Abstract
Recently, two aircraft from the Dryden Flight Research Facility of NASA's Ames Research Center were used in the general study of natural laminar flow (NLF). The first, an F-14A aircraft on short-term loan to NASA from the U.S. Navy, was used to investigate transonic natural laminar flow. The second, an F-15A aircraft on long-term loan from the U.S. Air Force, was used to examine supersonic NLF. These tests were follow-on experiments to the NASA F-111 natural laminar flow experiment conducted in 1979. Both wings of the F-14A airplane were "gloved," in a two-phased experiment, with full-span (upper surface only) airfoil shapes constructed primarily of fiberglass, foam, and resin. A small section of the F-15A right wing was gloved in a similar manner. Each glove incorporated provisions for instrumentation to measure surface pressure distributions. The F-14A gloves also had provisions for instrumentation to measure boundary layer profiles, acoustic environments, and surface pitot pressures. Discussions of the techniques used to construct the gloves and to incorporate the required instrumentation are presented. Comparisons with the technique used to construct the F-111 NLF glove are made. Problem areas, with explanations and solutions when available, are addressed. Finally, an evaluation of the value and success of these techniques to modify airfoils is provided.
