not be so strong and so deep, which results in not so thick
a Surface. That means the Chord can be proportionately decreased without adversely affecting the Camber. With the Chord decreased, the Span becomes relatively greater, and so produces a splendid Aspect Ratio, and an excellent proportion of Lift to Drift.'' ``I don't deny that they have rather got me there,'' said the Drift, ``but all the same, don't forget my increase due to the drift of the Struts and their bracing wires.'' ``Yes, I dare say,'' replied the Surface, ``but remember that my Spars are less deep than before, and consequently I am not so thick now, and shall for that reason also be able to go through the air with a less proportion of Drift to Lift.'' ``Remember me also, please,'' croaked the Angle of Incidence. ``Since the Surface has now less weight to carry for its area, I may be set at a still lesser and finer Angle. That means less Drift again. We are certainly getting on splendidly! Show us how it looks now, Blackboard.'' And the Blackboard obligingly showed them as follows: ``Well, what do you think of that?'' they all cried to the Drift. ``You think you are very clever,'' sneered the Drift. ``But you are not helping Efficiency as much as you think. The suction effect on the top of the lower Surface will give a downward motion to the air above it and the result will |
