Military aeroplanes; an explanatory consideration of their characteristics, performances, construction, maintenance, and operation, for the use of aviators . SO 60. ./sr .20 .25 .SC .is Ce^NTBK Of PFe35UfJ£ POS/TIC/V The lor Hat and ciuvcd sections, given on p. 57, are shown at the topof the page. Curve 2 shows the variation of Ka, for aspects of 1/3. 1; 3, and 3 shows the c. p. movement for the various aspect ratios. 1)1 The variations of Pa arc affected by Asiiect Ratio, and a veryremarkable distinction between squares and rectan^des in the man-ner in which Pa varies as the incidence is changed was discovered byEiffeL At angles in the neighborhood of 40°, on square planes. Pawas found to have values very much greater than Pgo. \alues of Ka for several different aspect ratios are given in CurveNo. 2, p. 60. It will be seen from this graph, that an increase of aspect ratioabove 1 is accompanied by increases of Pa, at low angles. But thereis a general falling off of this at 15° to 20°, as the aspect ratio is in-creased. For efficiency, at low angles, on flat planes it is advisabletherefore, to use the higher aspect ratios.
