Book Description
"This monograph presents a history of suction-type laminar-flow-control re- search in the National Advisory Commit tee for Aeronautics and its successor organization, the National Aeronautics and Space Administration, plus selected other organizations, with an emphasis on flight research. Laminar-flow control is a technology that offers the potential for improvements in aircraft fuel usage, range or endurance that far exceed any known single aeronautical technology. For transport-type airplanes, e.g., the fuel burned might be decreased a phenomenal 30 percent. Fuel reduction will not only help conserve the earth's limited supply of petroleum but will also reduce engine emissions and, therefore, air pollution. In addition, lower fuel usage will reduce the operating costs of commercial airplanes at least eight percent, depending upon the cost of the fuel and, therefore, will curtail ticket prices for air travel. Laminar-flow control is also the only aeronautical technology that offers the capability of designing a transport airplane that can fly nonstop without refueling from anywhere in the world to anywhere else in the world or that can remain aloft without refueling for approximately 24 hours. These enormous performance improvements that are potentially available for commercial or military applications, therefore, have made the concept the "pot of gold at the end of the rainbow" for aeronautical researchers."--P. 1.

Book Description
The effectiveness and practicality of candidate leading edge systems for suction laminar flow control transport airplanes were investigated in a flight test program utilizing a modified JetStar airplane. The leading edge region imposes the most severe conditions on systems required for any type of laminar flow control. Tests of the leading edge systems, therefore, provided definitive results as to the feasibility of active laminar flow control on airplanes. The test airplane was operated under commercial transport operating procedures from various commercial airports and at various seasons of the year. Maddalon, Dal V. and Braslow, Albert L.

Book Description
This document describes the design of the leading edge suction system for flight demonstration of hybrid laminar flow control on the Boeing 757 airplane. The exterior pressures on the wing surface and the required suction quantity and distribution were determined in previous work. A system consisting of porous skin, sub-surface spanwise passages ("flutes"), pressure regulating screens and valves, collection fittings, ducts and a turbocompressor was defined to provide the required suction flow. Provisions were also made for flexible control of suction distribution and quantity for HLFC research purposes. Analysis methods for determining pressure drops and flow for transpiration heating for thermal anti-icing are defined. The control scheme used to observe and modulate suction distribution in flight is described. Langley Research Center NAS1-18574; RTOP 522-32-31-01
