Abstract A toy glider constructed from expanded polystyrene with a wing having a V-shaped center section, a thickened leading edge having no dihedral at the leading edge and having a generally elliptical semispan trailing edge in planform with maximum chord outboard of half of the semispan. The maximum chamber of the wing occurs at the maximum chord with extreme ''''wash out'''' twist in the form of upward twist on the trailing edge of the wing from zero at the root to a maximum at the tip. The tip-leading edge of the wings has triangular projections on its underside for stability and minimization of tip vortex. The boom or body is constructed of expanded polystyrene formed into a V-shaped cross section and attached to the center section of the wing trailing edge. A balancing weight is located in the leading edge''s center, and a flat horizontal stabilizer is attached to the aft end of the body.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
A toy glider for flying in confined space comprising: a wing member having maximum chord and camber substantially outboard of its centerline and having its trailing edge curved increasing upward toward its tips to provide washout twist; a body member attached to said wing; and a horizontal stabilizer attached to said body member and spaced from said wing member; said stabilizer having a negative incident angle; the wing having a double thickness reinforced leading edge and having a generally elliptical semispan trailing edge planform; the maximum chord and maximum camber occurring no less than onehalf the semispan from the centerline and the trailing edge being twisted upward a maximum at the tip, diminishing to zero twist at the root; the leading edges of both sides of the wing being on the same straight line
Claim 2
Dependent Claim
134 words
A toy glider for flying in confined space comprising: a wing member having maximum chord and camber substantially outboard of its centerline and having its trailing edge curved increasing upward toward its tips to provide washout twist; a body member attached to said wing; and a horizontal stabilizer attached to said body member and spaced from said wing member; said stabilizer having a negative incident angle; the wing having a double thickness reinforced leading edge and having a generally elliptical semispan trailing edge planform; the maximum chord and maximum camber occurring no less than onehalf the semispan from the centerline and the trailing edge being twisted upward a maximum at the tip, diminishing to zero twist at the root; the leading edges of both sides of the wing being on the same straight line
