Analysis Tools
Engineering Analysis Tools
Aeronautica has developed a suite of proprietary engineering analysis tools to produce full flight-by-flight spectra and perform structural analysis. These tools have been successfully used on a wide variety of aircraft models in support of FAA certification efforts.
ASPEC Loadsgen
Flight-by-Flight Spectrum Development
The primary spectrum development tool. The origins of ASPEC Loadsgen date back to a code developed for the A-7D Corsair ASIP evaluation which the government publicly published in 1977. The current code uses the same methodology but has been greatly rewritten over the past 30 years. The latest 2020 revision was a significant overhaul to include enhancement in accuracy of results, inclusion of spectrum damage tags, and conversion to a full web-based application.
ASPEC Loadsgen utilizes the large database of FAA/DOT flight and ground load histories that have been published over the past 30 years. However, it is not limited to these — any load histories, if representative, can be used for particular applications. Both generic and specific mission profiles are provided along with the ability to use custom missions.
ASPEC Loadsgen has been successfully used to develop flight-by-flight spectra on a wide variety of aircraft models in support of FAA certification efforts. For more information, attend one of our Advanced Spectrum & DTA Applications Courses which provide in-depth discussion of ASPEC Loadsgen along with numerous example problems.
Additional Analytical Tools
Beyond ASPEC Loadsgen, Aeronautica has developed specialized tools for internal loads development and structural analysis.
FuseLoads
Fuselage Bending Internal Loads
Calculates fuselage bending internal loads for use in structural analysis and fatigue evaluations.
WingBox
Wing Multi Cell Internal Loads between 2 Ribs
Computes wing multi-cell internal loads between two ribs for detailed structural substantiation.
WingSpan
Wing Internal Loads Along Span of Wing
Calculates wing internal loads along the span for use in static and fatigue analyses.
Frame
Fuselage Frame Internal Loads
Determines fuselage frame internal loads for structural analysis of frame components.
SSF Solver
Stress Severity Factor Solver
Proprietary solver used in damage tolerance evaluations and fatigue analysis substantiations.
