March 18, 1952 w. R. CUSTER HIGH LIFT WING CHANNEL WITH MOVABLE WING Filed Jan. 3, 1950 awe/Wm WILLARD R CUS TE'R Patented Mar. 18, 1952 UNITED STATES PATENT OFFICE HIGH LIFT WING CHANNEL WITH MOVABLE WING Willard R. Custer, Hagerstown, Md. Application January 3, 1950, Serial No. 136,585

1 Claim. 1

This invention comprises high lift wing channels with movable wings, being an improvement of my application for airplane with high lift channeled wings, filed April 16, 1942, Serial No. 439,257 which is now Patent No. 2,510,959. In said application, Serial No. 439,257, the chan-- nels are equipped with inboard and outward ailerons each forming a part of a wing-like member superimposed on the channels and fuselage. With the present improvement, said member is eliminated and I employ wings movably mounted on the outer wall of each channel. Repeated tests have proven that this outboard wing is particularly effective for expeditious control without in any way mitigating the advantages and results flowing from the use of the channels.

In a practical embodiment of this invention, the outboard wings are operable from the cockpit by rotation of a single shaft which extends through the channels and into operative engagement with said wings.

Other objects of this invention will be apparent from the following description of the present preferred form of the invention taken in connection with the accompanying drawings The device of the present invention includes a fuselage 5 which may be of conventional con-- struction, including a tail structure 6. A channel 1 is carried by each side of the fuselage 5, the channel opening upwardly and extending in the direction of flight. The outer wall of each channel extends upwardly as indicated at 8. Operatively mounted in close proximity to the aft edge of each channel 1 is a propeller 9, the propeller being disposed, with respect to said channel, in such a manner as to be effective to produce a rearward flow of air over the equipped with suitable landing mechanism 10.

The outer wall of each channel 1, preferably at the juncture of the top of the channel wall and the extension thereof, is a wing ll provided with an opening I 2. A shaft I 3 extends transversely through the fuselage 5, channel 1 and openings [2, as shown in Figure 2. The shaft [3 is rotatably mounted so as to impart pivotal up and down movement to. the wings II as shown in Figure 3. The shaft I3 is rotated by a control element [4 conveniently mounted in the cockpit of the fuselage and in operative ,engagement with the shaft through suitable mechanism [5.

With the present invention substantially vertical lift and descent may be effected as with other types of Custer channel wing airplanes. It has been found that with thepositioning of the movable wings II substantially as herein illustrated and described, effective control may be exercised over the airplane by the pilot.

It is, of course, to be understood that various changes may be made in this invention without departing from the spirit and scope of the- REFERENCES CITED The following references are of record in the file of this patent:
