CLAIM

1. The ornamental design for a closed wing aircraft, as shown and described.

Description:

This application is related to the following application filed concurrently herewith: “Ring Wing and Spokes for Closed Wing Aircraft” and “Sinusoidal Circular Wing and Spokes for a Closed Wing Aircraft”.

FIG. 1 is a perspective view of a closed wing aircraft having equally spaced winglets on the fuselage in which all the rotors are deployed;

FIG. 2 is a front elevation view thereof;

FIG. 3 is a rear elevation view thereof;

FIG. 4 is a right side elevation view thereof;

FIG. 5 is a left side elevation view thereof;

FIG. 6 is a top plan view thereof;

FIG. 7 is a bottom plan view thereof;

FIG. 8 is a perspective view of a closed wing aircraft having equally spaced winglets on the fuselage in which the rotors on the spokes are deployed and the rotors on the closed wing are folded forward;

FIG. 9 is a front elevation view thereof;

FIG. 10 is a rear elevation view thereof;

FIG. 11 is a right side elevation view thereof;

FIG. 12 is a left side elevation view thereof;

FIG. 13 is a top plan view thereof;

FIG. 14 is a bottom plan view thereof;

FIG. 15 is a perspective view of a closed wing aircraft having unequally spaced winglets on the fuselage in which all the rotors are deployed;

FIG. 16 is a front elevation view thereof;

FIG. 17 is a rear elevation view thereof;

FIG. 18 is a right side elevation view thereof;

FIG. 19 is a left side elevation view thereof;

FIG. 20 is a top plan view thereof;

FIG. 21 is a bottom plan view thereof;

FIG. 22 is a perspective view of a closed wing aircraft having unequally spaced winglets on the fuselage in which the rotors on the spokes are deployed and the rotors on the closed wing are folded forward;

FIG. 23 is a front elevation view thereof;

FIG. 24 is a rear elevation view thereof;

FIG. 25 is a right side elevation view thereof;

FIG. 26 is a left side elevation view thereof;

FIG. 27 is a top plan view thereof; and,

FIG. 28 is a bottom plan view thereof.

In the drawings, the evenly-spaced broken line showing of the rotors and landing gear depicts environment and forms no part of the claim; the dash-dot-dot-dash lines represent boundaries of the claimed design and form no part thereof.
