Appeal 2007-0118
Application 10/175,612
SUMMARY OF DECISION
We REVERSE and REMAND.
THE INVENTION
Appellants invented a trailing edge device for transonic wings for aircraft
and a method for designing a wing by tailoring a spanwise variation of airfoil
segments (Specification 1:[0002] and 7:[0023]). Claim 1, reproduced below, is
representative of the subject matter on appeal.
1. A method for forming an improved trailing edge
wedge for a wing having a chord and a span, the method
comprising the steps of:
a) providing a baseline trailing edge wedge;
b) coupling the baseline trailing edge wedge to the
wing to form a baseline assembly;
c) segregating the baseline assembly into a
plurality of airfoil segments, each of the airfoil segments
being defined by a set of characteristics including a
trailing edge bluntness, a trailing edge included angle and
a trailing edge wedge height; and
d) tailoring a spanwise variation of the baseline
trailing edge wedge in terms of a trailing edge bluntness,
a trailing edge included angle and a trailing edge wedge
height at each of the airfoil segments to form the
improved wing assembly.
