Description
Patented May 8, 1945 UNITED STATES ATENT OFFICE AIRPLANE Jacob Wagner, Seattle, Wash.
Application February 8, 1941, Serial No. 378,049
2 Claims.
This invention relates generally to aviation and particularly to the heavier than air type of flying machine.
The main object of this invention is to construct a high speed plane having a relatively great carrying capacity.
The second object is to construct a plane of the class described in which all of the air from the slip stream as well as from the forward movement of the plane is utilized for lifting purposes.
The third object is to create a plane having the maximum amount of lateral stability.
The fourth object is to construct a plane which will present the minimum amount of resistance to the air.
The fifth object is to construct a plane of the class described in which a direct elevating action takes place at the forward end of the plane.
I accomplish these and other objects in the manner set forth in the following specification as illustrated in the accompanying drawing, in which:
Fig. 1 is a side .elevation of my improved form of airplane.
Fig. 2 is a plan of the airplane with a portion of one of the wings broken away.
Fig. 3 is a section taken along the line 3-3 in Fig. 2.
Fig. 4 is a front elevation of the plane.
Fig. 5 is a transverse section taken along the line 5-5 in-Fig. 2. 7
Similar numerals refer to similar parts throughout the several views.
Referring in detail to the drawing there is shown a fuselage l whose forward end II is provided with a concave tunnel I2 on its underside, whose upper side l3 extends from the forward edge 14 to the rearward edge l5. The edge I is widened laterally to form the tail members l6 whose lateral edges l1 merge gradually into the lower edge l8 of the forward end ll. Extending transversely across the bottom of the tunnel I2 is an air foil l9 which constitutes a support for 'the motor 20.
An elevator 2| is mounted in the rear of the foil l9 and operated by suitable controls (not shown). The usual form of landing wheels 22 and 23 are also indicated.
Extending laterally from the edges 18 are the wings 24 each of which is provided with motors 25. Motors and 25 are equipped with suitable propellers 26. Ailerons 21 are provided for the wings 24.
The controls of such devices are so well understood that it will not be illustrated or explained here.
At the rear of the tail I6 is attached the elevator 28 and the rudder post 29 has attached thereto a rudder 30 which is disposed midway along the breadth of the elevator 28 and directly above same.
It will be seen that in the operation of this plane, the air is drawn by the propellers 26 producing a definite direction on the airplane, and in addition, this same air is directed together with the surrounding air to converge within the tunnel l2 and along the supporting surfaces of the wings 24 producing the desired lifting and sustaining action.
It will be noted that the overall width of the airplane is relatively small but its supporting area, namely, the surfaces of the tail l6 and the underside of the tunnel l2, extend well to the rear of the wings 24.
In other words, the structure of the tail l6 and the walls of the tunnel 12 does not offer additional resistance as would increased wing length} thereby reducing the power requirements necessary to fly the airplane.
Attention is drawn to my former Patent No. 1,956,054, dated April 24, 1934, over which the airplane described herein is an improvement as far as speed, load carrying ability, and flying is concerned, although it is possibly less stable than the plane described in my former patent.
Attention is especially drawn to the fact that with the present construction, the forward elevator 2! is placed behind the air foil H! which is in front of the axis of the forward landing wheels 22, while the rearmost elevator 28 is behind the axis of the rearmost landing wheels 23. It is clear that the additional lift provided by the forward elevator 2t will greatly assist in taking off and in landing an airplane, especially one built along the lines herein described and illustrated.
I claim:
1. An airplane having in combination an elongated fuselage having elongated central wings extending along the length of said fuselage and terminating in a widened tail at its rearward end and having its forward end arcuately curved on its underside to form a longitudinal tunnel thereunder; wings projecting laterally from the lowermost portions of the forward end of said fuselage and having lateral ailerons on the outermost trailing edges thereof and a central elevator disposed in front of said lateral ailerons at the lowermost side of said tunnel, elevators disposed mum depth near the rearward end of said cen-.
tral wing, a propeller unit disposed within the channel, an air foil constituting a brace across the lower edge of the channel and also forming a support for said propeller unit, a central elevator mounted behind said air foil and lateral wings extending from the lower edges of the forward end of said central wing, the outermost trailing edges of said lateral'wing having ailerons thereon disposed laterally of and behind said central 10 elevator.
JACOB WAGNER.
