Johnson, W.H. (author)
This paper describes a simple device which enables the in-phase and quadrature components of any harmonic in a complex waveform to be determined with respect to an external sine wave of the same frequency. It is potentially a very useful method for the elimination of noise and other spurious effects in flight flutter testing and has an...

The effect of incidence on sonic bang intensities is treated incorrectly in some of the literature. This Note considers the pressures at a large distance from a smooth, slender aircraft at incidence in steady flight. The results are used to correct the erroneous formulas obtained elsewhere for an aircraft in unsteady flight. Two simple examples...

A study is made of the aerodynamics of wings executing simple harmonic oscillations. The wings considered are infinitesimally thin and slender; they may have longitudinal camber and curved leading edges. Leading-edge separation is simulated by an isolated line singularity of vortex type. The value of the reduced frequency is assumed to be such...

Two methods for measuring tailplane loads have been tested in flight on a Hunter F.2 aircraft. One method used modified tailplane mountings which provided a satisfactory means of checking, in flight, the datums of their strain gauge bridges. Although hysteresis and other non-linearities in the load calibrations, together with fairly rapid...

Surface-pitot tubes have been used to measure local skin-friction in free-flight. Measurements were made at 10 stations on a simple delta-winged model flying at zero lift at Mach numbers between 2.2 and 1.2. This Note describes the design and development of the instrumentation and the methods employed to analyse the experimental data. Good...

A method is established on the basis of linearized thin-wing theory for the calculation of pressure distribution, in steady supersonic flow, on wings of arbitrary planform with subsonic leading edges. An algebraic expression is derived by exact integration for the incidenoe coniribution and a computational formula, based on Gaussian integration,...

A cylindrical plasma is considered to be heated by R.F. currents to a temperature of about 8000ºK in argon at a pressure of 50 x 10- 6 atmospheres. An estimate is made of the skin depth and of the uniformity of the plasma in the central region both with and without an axial magnetic field. A skew solenoid is suggested to provide a magnetic field...

This Note describes a systematic investigation of the pressure fields produced within the R.A.E. 6 inch shock tube at low shock speeds. This work was undertaken to investigate the tube's suitability as the driver of a cold high-density hypersonic tunnel. It is concluded that the tube is suitable and should produce expanded flows at Mach numbers...

A preliminary discussion shows the need for an alternative to the classical friction brake, where a hinged link must be able to resist hingemoment at any point throughout its arc of travel, thus precluding stepped or toothed devices. An alternative is then proposed in which the link movements cause continuous exchange of fluid between two sealed...

Tests were carried out on center section wing panels of 7075 material. The loading was based on strain gage records obtained by flying in turbulent air. Load sequences applied include random loading and programmed loading, with and without ground-to-air cycles. A testing machine was developed for this purpose. Data are presented on critical...

In connection with the problem of the fatigue strength of lugs with interference fitted bushes an investigation is made of the shrinking stresses in such a lug in the unloaded condition. A comparison is made with the stresses in a lug with an interference fitted solid pin.

In dit rapport wordt een beschrijving gegeven van een onderzoek dat beoogt na te gaan in hoeverre de gauge factor wordt beïnvloed door de stroomsterkte. Er zijn twee typen rekstroken onderzocht n.l. draad- rekstroken en folie-rekstroken. Van beide typen zijn zowel korte als lange stroken beproefd. De beproefde rekstroken zijn Impa 10/120 PA 1 en...

The basic principles of power spectral methods are described. The most practical formula's are given and as an example a simplified gust loading problem is dealt with in soma detail. A number of concepts occurring in the practical determination of power spectra, such as aliasing, prewhitening, slicing effect, truncation are discussed and a few...
