LEEOR C. MCCARTNEY AND EMORY CROYLE, 0F ALTOONA, PENNSYLVANIA AIRCRAFT Application filed February 11, 1929.
This invention relates to improvements in aircrafts, the general object of the invention being to provide the craft with a horizontally arranged propeller above the fuselage and to form air passages in the wing and fuselage which are so arranged that the air currents from the horizontal propeller will strike the currents from the main propeller and thus produce a whirling motion of the air under the wing, which will act to raise In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several vows, and in which Figure 1 is a side view of an aeroplane constructed in accordance with this invention.
Figure 2 is a top plan view.
Figure 3 is a fragmentary front view, with parts in section.
As shown in these views, each section 1 of the wing of the plane has its inner end cut away to form a substantially semi-circular recess 2 and a substantially semi-circular member 3 is connected with the curved walls of this recess, this member being of considerably greater length than the thickness of the wing. The member flares upwardly and outwardly from its lower end, as clearly shown in Figure 3. The fuselage of the plane is formed with a raised top portion 4, with a curved recess 5 in each side thereof, the walls of the recess sloping upwardly and inwardly from the bottom, as clear- 1y shown in Figure 3. The recesses 2 and 5 form a passa e at each side of the fuselage which tapers rom top to bottom, and a horizontally arranged propeller 6 is mounted Serial No. 339,100.
on the raised portion 4 and is suitably driven from the motor of the plane or from an auxiliary motor. The blades of this propeller are so arranged that the air currents produced thereby will be forced through the passages and the walls 5 of such passages will tend to direct the air currents toward the tips of the wings, but as these currents are acted on by the currents from the propeller 7, they will be deflected rearwardly and these combined currents will cause other currents to act on the under side of the wings in such a manner as to cause a lifting movement to the ship. The arrows in the figure show the action of the currents.
It is thought from the foregoing description that the advantages and novel features of theinvention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
'What we claim is An aircraft of the class described having substantially semi-circular recesses in the inner ends of its wing sections where the sections join the fuselage of the craft, a substantially semi-circular member attached to' the curved wall of each recess and flaring upwardly and outwardly, the fuselage of the craft having a raised portion having substantially semi-circular recesses 1n its sides which slope upwardly and inwardly, the two pairs of recesses forming a vertically arranged air passage, 3. horizontally arranged propeller on the top of the raised portion for forcing air through the passages this air being deflected toward the tips of the wings. by the walls of the semicircular members and this air, after leaving the lower parts of the passages, will be acted on by the air from the main ropeller.
In testimony whereof tures. LEEOR C. MGCARTNEY.
EMORY CROYLE.
