Ultravia Aero International Inc.
embarked into a type certification program for the
Pelican 2-100 to obtain certification under Transport
Canada Chapter 523 – Very Light Aircraft (VLA)
and FAA (FAR23-VLA). The Pelican 2-100 is a two seat,
single engine, high wing airplane of conventional
design, consisting of a semi-monocoque composite fuselage,
metallic wings and metallic empennage.
To assist in this certification process, Martec Limited
analyzed the structural components of the Pelican
2-100 using classical methods and/or Finite Element
Analysis (FEA) as required. The FEA models for the
engine mount, main landing gear, horizontal stabilizer,
vertical stabilizer, wing, and fuselage were created
using Altair’s “HyperMesh” pre-and
post-processor. Combinations of static linear, buckling
and fatigue analyses were conducted using MSC/Nastran.
Martec Ltd conducted an extensive material test program
to determine the A- and B-basis material properties
required for the FE analysis. Using the results obtained
from the FE analyses, classical analyses were performed
to evaluate the margins of safety of the aircraft
major structural joints.
Martec Ltd. documented the results of these analyses
and material qualification tests in a format suitable
for submission to Transport Canada to support the
type certification requirements.
