Stirling is a recognised industry leader in loads
generation for aircraft design. We have provided
whole aircraft and component loads for new and
modification upgrade programmes, including novel
designs.
We are experienced in calculating static, dynamic and
fatigue loads, covering flight loads in response to gust
and manoeuvre, and ground loads resulting from
ground manoeuvres, take off and landing.
Our engineers have an impressive knowledge of
EASA, FAA and military standards – including
standards for new and supplemental certification.
Stirling holds CVE status for aircraft loads
clearances under EASA Part 21J.

Stirling provides Computational Fluid Dynamics
(CFD) expertise and analysis using Star CCM+
for both internal and external flows. Our CFD
experience spans both aircraft and marine
applications.
Our CFD expertise supports and complements
the design process. Stirling’s extensive toolset
enables our engineers to generate and
interpret the aerodynamic database providing
design confidence, covering modification and
new design concepts.

Stirling has developed a number of specialist in-house
tools to calculate performance characteristics for both
fixed and rotary wing aircraft.
These calculations support concept studies, design
and trade-off studies involving:
• Take-off and landing
• Cruise, climb and descent
• Steady manoeuvring
• Payload, range and fuel burn
• Failure conditions: e.g. one engine inoperative
• Parametric studies
