“…For successful experiments, serious problems must be solved, which can be discussed only briefly in this paper. One problem is the simultaneous measurement of both steady and timedependent pressures and displacements' 6 ' and their recording with a rapid data acquisition and analysis system: the 'Presto' system is used at RAE Bedford' 7 -8 '. Welsh recently reviewed these problems' 9 '.…”

Time-dependent aerodynamics is primarily concerned with the pressure distributions developed by moving control surfaces, such as the oscillation of a trailing-edge flap, the rapid extension of a spoiler, or the pitching of a canard.Some recent experiments in time-dependent aerodynamics are reviewed. These include wind tunnel dynamic interference and its attenuation, the aerodynamics of an oscillating trailing-edge flap, the reduction of response to turbulence by active control, the aerodynamic characteristics of rapidly moving spoilers, and the time-dependent aerodynamic characteristics of supercritical wings.The paper concludes with a discussion of aeroelastic problems at subsonic and transonic speeds and with some buffeting measurements in a cryogenic wind tunnel.

“…Before the skins were bonded together, 56 small transducers (Kulite Type XCQL-093-A25, absolute pressure range 0 to 25 psi) were inserted to measure static and dynamic pressures simultaneously using specially designed RAE amplifiers' 8 '. The transducers were attached to the upper skin of the wing at the nominal positions given in Fig.…”

Summary This paper describes a series of steady and time-dependent pressure measurements on a half-model of a rectangular wing of aspect ratio 4. The wing was mounted on a half-body attached to a sidewall of the RAE 8 x 8 ft wind tunnel and the tests were made at Mach numbers of 0·20, 0·42, 0·70, 0·80 and 0·85 with fixed transition and a Reynolds number of about 2·5 x 106 at the highest Mach number. The wing was oscillated about its mid-chord axis at four frequencies giving frequency parameters up to 1·15 at M = 0·20 and 0·25 at M = 0·85. The static angle of incidence was varied from –10° to + 10°. Selected mean and oscillatory measurements are offered as a challenge to computational fluid dynamicists for this simple three-dimensional configuration. Comparisons are made with calculations by means of subsonic linearised theory and recent transonic small perturbation methods. The measurements are of particular interest at transonic speeds, where both attached and incipient separated flows are considered.

“…Another type of the conventional strain gauge is the semiconductor strain gauge, which processes higher gauge factor than the metal foil strain gauges. However, the semiconductor strain gauges are easily affected by the ambient temperature, which is difficult to compensate and limits their widely use in experimental analysis [5].…”

A strain-gauge-type precision displacement sensor, which is developed for positioning of a micro-XY stage, is described in this paper. The designed patterns of Cr-N strain gauges are directly sputtered on zirconia plates, which would be used as leaf springs in the micro-XY stage, by using photolithography processes to form a Wheatstone bridge circuit. The patterns of the strain gauges on the leaf spring are optimized to be sensitive area so that the displacement of the stage can be measured with a higher sensitivity. The experimental results confirmed that the designed sensor is applicable for sub-micrometre-scale positioning of the micro-XY stage.
