This invention relates to aeroplanes and it comprises an aeroplane of the monoor biplane type provided with wings having upwardly curved front and end edges, perforations in the end edges and in portions of the rear edge, means for forcing air intoisaid wings and through said perforations, said. aeroplane also being provided with a fuse:

M lage having substantially the same width throughout it length, the fuselage being substantially rectangular in cross section with its bottom side inclined upwardly and. rearwardly beginning at a point just beyond the i region of the wings; landing gear comprising '15 pairs of wheels secured to the fuselage and positioned one pair at its front end, a second pair intermediate the ends of the fuselage and a third pair 'atthe rear endof the fuse lage,'the landing gear supporting the fuselage upon the ground in a position to bring its inclined bottom portion parallel to the ground and an extended tail portion hingedly secured to the rear of the fuselage so'that it can be raised during landing of the plane and remain in this raised position while the plane is on the ground, its purpose being to prevent the tail from striking the ground;

all as more fully hereinafter set forth and as claimed. V

' In describing the invention in detail reference Will be had to the accompanyingdraw;

Figure 2 is a side view of Figure 1. N Figure 3 is a frontview of a bi-plane' con- 2 ,Structed in accordance with this invention.

Figure 4 is an elevation of Figure 3. Figure 5 isan elevation, partly in section, showing the bi-plane resting on the ground. Figure 6 is a plan view with the upper wing-in section.

Figure 7 is a ure 6. v

In these views, the fuselage is shown at A and said fuselage is preferablyconstructed of the shape shown in the drawings, which section on line 7-7 of Figshows the fuselage of considerable height and relatively narrow width, with its front end V shape in cross section. The front part'of the fllselage is supported on the gear B and l the bottom of its rear partslopes upwardly andrearwardly, with the wheels 1' at the ends ofthis slopingpart so that when the lane is resting on a surface, as shown in igures'2 and 5, the three sets ofWheelsWill.

contact the surface. A rear extension2 a is formed at the top part of the fuselage and a tail part 3 is hingedly connected to the rear end of the extension, as shown at 4;, so

that this tail part can be "moved to ahorizontal position or to a position where there is 8 no danger of it contacting the ground-when the plane is at rest; A cable 5 is connected with't'he' tail part for moving the same up+ wardly'on its hinge and a second cable 6 is connected with'the tail part for moving the 7 same downwardly. These cables extend to a-point adjacent the pilots seat or any other suitable place in thefuselage and are con nected with suitable means for actuating the 1 cables to raise or lower the tail part." This 5 tail-part carries the usual rudders 7'which are operated from the interior of the fuselage through means, includingthe'cables-8.' i The wing of the "monoplane is shown at 9 and the wings for the'bi-plane at 9; Each wing has the ailerons 10 pivoted to the rear edges thereof, these ailerons being operated in any desired manner from the interior of the fuselage. Each wing is of hollow construcv tion, as shown at 10-, with its end and'front edges curved upwardly as shown at 11. I Perforati'ons 12'are formed in the end edges and in the outer portions of, the rear edge, as shown in Figure 6, and a 'conduit'13 leads i from the interior of each wing to the rearend of the fuselage under the extension '2. The conduit is formed in the fuselage and a motor driven emu is arranged in the COnduit and acts to draw air through the conduit so that I the air will pass into the hollow wing and escape through the perforations 12, as shown in Figures 5 and 6. In the bi-planetype, the conduit 13' for the lower wing extends through a portion of the sloping bottom of the fuselage, as shownin Figure 5-. Par- 9 titions 15 are arranged inthe wingand act to direct the air from the fan 14 forwardly against the inner face of the front edge of the wing and then outwardly and rearwardly through the perforations 12, as shown by the I arrows in Figure 6.

side edges of the wings facilitate the taking ioff and rising of the plane by eliminating the resistance of air pressure on the'top of f the wings and gives greaterfspeed in.flight.i o The air passing through the perforation in the end edges and rear portions oft-he wings lessens the degree of vacuum formed at these points when the'plane" is in'flight' and acts similar to a lubricant zinasmu ch as it lowers the airfriction at these points and permits the plane to travel at a greater rate ofspeed; For-this purpose it is not necessary that anyllgreatamount of air be forcedinto fuselage-intheimonoplane type and a numberkofanotors M are supported at eachfside of the body in the bi-plane typei These motors are supported by the members 16 and each motor has a propeller 17 at -each end of ts shaft. These motors may be connected in a Y stationary manner to the supporting means or they may be pivotally connected'so that they-maybe adjusted about a-horizontzil-axis by means of theshafts 18connected withthe I pivotal rpoints of themotors and operated by suitable .meanswithin the fuselage so that byturning the shafts, :the motors canibe tilted to ;direct the air,"'currents against -;.the ailerons when the s'ameare turned downwardly andagainstthe-wings, as shown in F-ig- 4 .ure-2.* This will facilitate the take g'ofi', of

the plane. When the aeroplane rises, theimotion, as shownin Figure L a A planeconstr-ucted asf described is-ca pable ,Of carrying a heavyload and" can be 7 navigated safely through violent storms.- It

can also be started easily with its capacity load By shaping the body as shown, the

wings set on an angle when thejplane is' at rest so that atthe take 0d, the air, striking the wings, will facilitate the rising of the .planeand, of course, this actionis further 'facilitated'by the lowering of the ailerons.

:When in flight, the wings are in a horizontal position and by forming'the edges of the wings as shown, the pressure above the'wings is eliminated; pThe peculiar shape of the fuselage places the air pressure attheifront, asthere is no pressure on the sides. The sides are slightly tapered downwardly, which acts to cause the airto produce an upward It is thought iro m thef oregeing dsrittion that the 1 advantages and; novel features of the invention will be readily apparent.
