Laminar Flow Aircraft Certification

This workshop on laminar flow aircraft certification was an outgrowth of the
NASA/AIAA General Aviation Technology Conference held at the NASA Langley Research
Center in 1984. At that conference, several people from NASA Langley, the Federal
Aviation Administration, industry, and universities expressed the desire for a forum
to discuss the effect of laminar flow aerodynamics on certification procedures for
future aircraft. It was felt that such a forum should bring together researchers
concerned with maximizing the benefits of laminar flow aerodynamics, manufacturers
concerned with developing significantly improved new aircraft, and regulators con-
cerned with applying proper certification procedures to insure safety. By bringing
together these diverse interests to address the common goal of developing new air—
craft with superior efficiency, it was hoped that an improved understanding of
laminar flow aerodynamics technology would be obtained and that improved communica—
tions between the participants would serve to guide future efforts.

The workshop was structured to review the state of the art in laminar flow
aerodynamics technology and explore technology needs in four areas: test tech—
niques, aerodynamic research, operational procedures, and manufacturing technology.
Each participant at the workshop was assigned to a working group in one of these
four areas. In order to provide a foundation for these working groups, the workshop
began with invited papers addressing each area.

The papers included in this report are largely as presented. The recommenda—
tions of each working group are also included. Identification of commercial prod—
ucts in this report does not constitute official endorsement, expressed or implied,
of such products by NASA. The special efforts of Frances E. Sabo of the NASA
Langley Research Center in organizing the workshop and of Richard A. Vandame of the
SAE in providing meeting facilities for this workshop in conjunction with the 1985
SAE General Aviation Aircraft Meeting and Exposition are gratefully acknowledged.
