If the ends of the aeroplanes on one side were bent downwards, those on the FIG.
He constructed models to fly by three different methods: - (a) by means of screws acting vertically upwards; (b) by aeroplanes propelled horizontally by screws; and (c) by wings which FIG.
It consisted of the following parts: - (a) A system of aeroplanes arranged like the capital letter T at a certain upward angle to the horizon and bearing a general resemblance to box kites; (b) a pair of very light propellers driven at a high speed; and (c) an exceedingly light and powerful petrol engine.
It was hoped that when the aeroplanes were wedged forward in the air by vertical screws, or by the body to be flown, each aeroplane would rest or float upon a stratum of undisturbed air, and that practically the aeroplanes would give the same support as if spread out horizontally.
Very good idea of the arrangement - a, b, c representing the superimposed aeroplanes, d the tail, e, f the screw propellers.
