Appeal No. 2003-0552
Application 09/190,318
Claims 1 through 16 have been canceled. Claims 17, 18, 20
through 22, 24 through 26, 28 through 30 and 32 have not been
appealed.
As noted on page 1 of the specification, appellant’s
invention relates to a system or device for operating a
controlled member on a rotary-wing aircraft, particularly a
helicopter. The controlled member, in the case of a helicopter,
may be the main lift and forward propulsion rotor or the
countertorque tail rotor. An objective of appellant’s invention
is to provide an improved mechanically-based control system or
device which allows high-performance control of the type achieved
with fly-by-wire control, but with high dependability, owing to
the fact that it is essentially a mechanically-based system and
can continue to operate when its electrical part (i.e., the
computer) breaks down, and at a low cost, because it is based on
a conventional mechanical system/device and requires no
redundancy between its constituent elements. A copy of parent
claims 17, 21, 25 and 29 (not appealed), and dependent claims 19,
23, 27 and 31 (which are on appeal) can be found in the Appendix
to appellant’s brief.
