AEROPLANE WITH V-SHAPED WINGS Filed June 22, 1931 J l6 7' if? f 16 I gwuewioz N% W/izEBeZZ Patented Feb. 21, 1933 PATENT OFFICE WILLIAM ERNEST BELL, F CHARLOTTE, NORTH CAROLINA AEROPLANE WITH 'V-SI-IAIPED WINGS Application filed June 22, 1931.

The object of my invention is to provide an aeroplane having a novel wing construction adapted to increase the speed of the aeroplane and to increase its lateral stability and its lifting power. It is also an object of my invention to apply my improvements to planes having either the usual cockpit or to a cabin plane.

I obtain the objects of my invention by the means illustrated in the accompanying drawing, in which,

Figure 1 is a top plan view of my invention;

Fig. 2 is a side elevation of same;

Fig. 3 is a section through one of the wings on the line 33 of Fig. 1, showing the curvature of the wing in cross section; and

Fig. 4L is a rear elevation of the wings and detached from the body of the areoplane.

Like numerals designate like parts in each of the several views.

Referring to the accompanying drawing, there is illustrated an aeroplane having a conventional fuselage 1 and cockpit 2. I provide novel V-shaped wings 3 fastened to the fuselage at the central portions 8 and also secured to same by the central brace 9 which is fastened to the body of the aeroplane back of the cockpit as shown in Fig. 1; also braced by the lateral braces or straps which are fastened to the underside of the wings and to the sides of the fuselage as illustrated in Fig. 3. The wings 3 are suitably affixed or attached to the fuselage or to each other as by members 5. It will be especially noted that the nose or apex 4 of the aeroplane wings may, if desired, extend over and be positioned forward of the aeroplane propeller 13, and that the wings terminate in substantially pointed ends 16 as shown in Figs. 1 and 2. The wings extend rearwardly at an angle of approximately 50 degrees to each other, as shown in the drawing, and slant upwardly from the fuselage at an angle of between 8 to 10 degrees from a plane drawn horizontally through the point of connection through the wings and the fuselage as shown also in the drawing.

The wings are preferably provided with 50 suitable shatterproof glass windows 6 to en- Serial No. 546,082.

able the pilot to have a clear view through the wings in the case of aeroplanes of the cockpit type. In the cabin type of plane such windows are unnecessary.

I provide a suitable or conventional horizontal rudder 10 having movable rudder sections or vanes 11, and a conventional vertical rudder 12. The rudders 11 and 12 and ailerons? are operated by any suitable conventional means, not shown in the accompanying drawing and not claimed as a part of this invention.

When the aeroplane is in operation the V-shaped or three-pointed wings 3 have a V tendency to increase the speed of the plane, to improve its lateral stability andto increase its lifting power. The wings are so mounted that the plane is evenly balanced and the Wings form a true V-shape. A novel and advantageous feature of the invention is the 7G disposition of the forward portion of the wings over the propeller 13. A greater lifting power and a more even balancev of the plane is obtained thereby. The V-shaped wings have a tendency to reduce a great deal of wind resistance, and thereby to increase the speed of the plane.

The invention may also be applied to cabin planes and-when applied to cabin planes it is not necessary to provide the glass windows 6 in the wings.

What I claim is:

In combination with an aeroplane, substantially V-shaped wings disposed at an angle of approximately 50 degrees to each other, said wings terminating in substantially pointed ends, said ends being disposed in the same plane as the main body of the wings and the wings being disposed in an upwardly slanting direction of between approximately 8 to 10 degrees from the point where they are attached to the fuselage to increase lateral stability.

WILLIAM ERNEST BELL.
