Sixth Meeting, Second Half, 62nd Session

Proceedings

  • Man and the Machine

  • Martin Flack
  • Published online by Cambridge University Press:
    28 July 2016, pp. 393-410

  • What may be termed broadly the medical aspects of flying are far more wide–reaching than is generally supposed, especially since such a term embraces both the physiological and psychological aspects of the subject. All the while, therefore, that man acts as the controlling and co–ordinating mechanism of the machine, the study of man in relation to his machine must occupy an important place in the progress of aviation. It is because this aspect of the subject has tended to be somewhat overlooked that I venture to address this Society again to–night.

    In the first place I wish to consider what happens when a man learns to fly. As the result of information gleaned by his various senses he is taught, according to his aptitude, to perform or to try to perform certain arm and leg movements which will control the machine safely while it is in the air. To do this, however, in addition to perceiving, he must in certain circumstances display judgment before he acts, although, as he becomes more experienced in flying, he will automatically perform certain movements in response to certain sensations.

Meeting Report

Research Article

  • The Articulated Connecting Rod

  • E. J. Fearn
  • Published online by Cambridge University Press:
    28 July 2016, pp. 133-141

  • In the past the usual method of dealing with the articulated rod has been to treat the problem graphically. Although this method may be sufficiently accurate for a first approximation the inherent difficulties often lead to serious errors after the first few stages. A graphical method is always sufficiently accurate to determine the travel of a piston operated by an auxiliary rod ; but, the double differentiation of the displacement curve by graphical means (to obtain the acceleration curve), is not only inaccurate but a long and tedious operation.

    To remedy this defect a Fourier's series has been developed which can be differentiated at sight and which gives a remarkable accuracy.

    The geometrical properties of the mechanism have been analysed and thus equations are formed giving the resultant radial and tangential components at the crank pin, the bending forces and tensions on the master rod, etc.

Fifth Meeting, Second Half, 62nd Session

Proceedings

  • The Spinning of Aeroplanes

  • L. W. Bryant, S. B. Gates
  • Published online by Cambridge University Press:
    28 July 2016, pp. 619-688

  • We should like to preface our essay on the subject of spinning by mentioning the circumstances under which our investigations were carried out and the sources of our information. The Panel of the Aeronautical Research Committee which has been appointed to deal with all questions connected with the stability and control of aeroplanes was requested in 1924 to consider the urgent problems connected with the alarming accidents due to certain machines failing to retover from a spin. After the issue of a preliminary reporton the situation by the Panel, the writers of this paper were asked to go into the whole question as far as existing information from full-scale and wind tunnel experiments would permit. We have had ready access to all available data, coming chiefly from Farnborough on the full-scale side, and from the N.P.L. on the model side.

Research Article

  • Research on Channel Wall Interference*

  • J. H. Parkin
  • Published online by Cambridge University Press:
    28 July 2016, pp. 1110-1149

  • An investigation of channel wall interference with the object of verifying experimentally the accuracy of the results given by the theory developed by Prandtl and extended by Glauert. Tests were made, with cylinders and aerofoils, using the “ mirror ” method, for some ten different channel sizes. The results show :

    1. 1. The presence of the channel walls results in an increase in the drag of a symmetrical body, such as a cylinder.

    2. 2. Agreement with the theoretial corrections for incidence and drag for channels of reasonable size.

    3. 3. The extent and nature of the wall interference effects on the aerodynamic characteristics of aerofoils in much restricted streams, beyond the limits of applicability of the theory.

  • Line-Squalls*

  • M. A. Giblett
  • Published online by Cambridge University Press:

  • The subject of “Line-squalls” is one which has not been entirely neglected in the proceedings of this Society, but it has not hitherto been treated in any degree of detail. Sir Napier Shaw, in a lecture delivered on January 7th, 1914, on the subject of “Wind Gusts and the Structure of Aerial Disturbances,” briefly cited the line-squall as a phenomenon involving a violent commotion in the atmosphere, illustrating his remarks by sketches and meteorological records relating to a well-marked instance on October 14th, 1912, at Aberdeen.

  • The Effect of Reduced Intake-Air Pressure and of Hydrogen on the Performance of a Solid Injection Oil Engine

  • G. F. Mucklow
  • Published online by Cambridge University Press:
    28 July 2016, pp. 17-59

    1. (a)Introductory.—The paper deals with experiments carried out in the engineering laboratories of the University of Manchester on a Crossley solid-injection oil engine in which small quantities of hydrogen or coal gas were introduced along with the air supply to the engine.

    2. (b)Range of Investigation.—Three series of trials were run with hydrogen, each at a different load, namely, 53·4, 39·4, and; 24·4 b.h.p. The maximum amount of hydrogen used was slightly more than 3 per cent. by volume of the air supply, corresponding, at the lightest load, to some 14 per cent, by weight of the oil fuel supply.

      Three corresponding series of trials were run using coal gas in place of hydrogen, the maximum volume of gas employed being 5 per cent. of the air supply. At the lightest load this corresponds to approximately 2·4 times the weight of fuel oil used.

    3. (c)Conclusions.—Such quantities of hydrogen or coal gas can be used satisfactorily in the type of engine considered. No trouble was experienced due to pre-ignition or other causes, and the engine appeared to run more sweetly when gas was being used.

      When running at constant load and speed, the admission of small quantities of gas appears to cause combustion to take place at a slower rate, giving a lower maximum pressure and more burning down the expansion stroke. The thermal efficiency is in consequence slightly reduced, while the heat-losses to exhaust are increased.
