THE reader who asks for more wood and less trees in technical discussions of wing flaps has my sympathy, since I have myself been responsible for some denseness of undergrowth. In this article 1 intend to avoid detail somewhat ruthlessly, to stand back and get a long view of the subject, to give, in fact, a freehand sketch rather than a blue print.

Broadband trailing edge noise from a sharp-edged strut
The Journal of the Acoustical Society of America, 2011This paper presents experimental data concerning the flow and noise generated by a sharp-edged flat plate at low-to-moderate Reynolds number (Reynolds number based on chord of 2.0 × 105 to 5.0 × 105). The data are used to evaluate a variety of semi-empirical trailing edge noise prediction methods.

Trailing-edge region of airfoils
Journal of Aircraft, 1989Measured and calculated results obtained in a set of trailing-edge flows are examined to consolidate understanding of the requirements and implications for airfoil calculation methods. The experiments investigated sharp, round, and blunt trailing edges, attached and separated turbulent boundary layers, and boundary-layer interaction with the wake of an

Divergent-trailing-edge airfoil flow
Journal of Aircraft, 1996The influence of recirculating flow on drag reduction associated with a divergent-trai ling-edge (DTE) airfoil is provided by comparing the flow structure around a supercritical airfoil with a blunt trailing edge to that around the same airfoil after DTE modification.

Blade Trailing Edge Heat Transfer
Volume 1A: General, 1980In this article measurements of heat transfer, pressure loss, and friction factor inside simulated trailing edges of turbine blades are presented. The trailing edges considered are vented and the internal heat transfer surfaces are extended by means of staggered arrays of pillars interconnecting the blade pressure and suction surfaces.

AbstractChapter 3 focuses on the high-Reynolds number flow of an incompressible fluid near the trailing edge of a flat plate. It begins with Goldstein’s (1930) solution for a viscous wake behind the plate, and shows that the displacement effect of the wake produces a singular pressure gradient near the trailing edge.

The optimal location of flaps for multiple-flap configuration shown in Chap. 4 was obtained through parametric studies and the objective was to minimize only the hub vibration levels. These trailing-edge flaps are typically operated using piezoceramic actuators placed inside the blade section.

A Trailing-Edge Noise Model for Serrated Edges
21st AIAA/CEAS Aeroacoustics Conference, 2015© 2016, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved. This paper is concerned with the development of a theoretical model for the prediction of the sound radiated by serrated trailing-edges. The proposed model is based on Fourier expansion and Amiet's formulation.
