Industry-leading, Easy-to-use, Intuitive User Interface for Predicting Air Vehicle Loads
Flightloads is MSC Software’s industry-recognized, easy-to-use, intuitive interface that integrates the aeroelasticity capabilities of MSC Nastran and the FEM modeling functionality of Patran. It is widely used in the prediction of external maneuver and dynamic loads on air vehicles. Flightloads supports typical modeling and analysis processes that can emulate the workflow commonly found across the aerospace engineering community, especially in the discipline of aeroelasticity.
Flightloads UI can be leveraged to define the aerodynamic and structural models, perform aerodynamic calculations, analyze the combined structural-aerodynamic model to provide both components and total vehicle aeroelastic responses. It can also be leveraged to view the results and produce external loads, and store intermediate results for subsequent retrieval in further analyses.
It enables engineers to accurately, and efficiently predict external air vehicle load, offers improved aero-structural coupling technology and validation tools. It leverages the capabilities of MSC Nastran and Patran for delivering unmatched external load prediction capabilities. Organizations have the capability to maintain competitive advantage through the integration of in-house, proprietary tools with Flightloads. It offers seamless integration of external and internal loads.
Key Capabilities
Aerodynamic Modeling
Flightloads offers extensive aerodynamic modeling capabilities by leveraging Doublet Lattice Method surfaces and bodies (MSC Nastran CAERO1 & CAERO2). It essentially automates modeling with error detection and correction methods & creates external integrated loads monitor points over the mesh. It also displays extensive model visualization and query capabilities and supports multiple aerodynamic mesh representations.
Aero-structural Coupling
Flightloads interactively verifies spline relationships by leveraging existing or automatically generated structural displacements. The results of aero-structural coupling are automatically displayed and animated. Additionally, it stores an aerodynamic database for data archives that can be reused in a hierarchical form for multiple models and multiple conditions. It supports nonlinear data over all trim parameters.
Static Aeroelasticity Support
Flightloads is widely used in computing subsonic and supersonic aerodynamics internally and creates simultaneous symmetric and anti-symmetric boundary conditions. It leverages analysis methods such as flexible trim, flexible increments, and rigid trim and uses the nonlinear aeroelastic trim method in the case of nonlinear aerodynamics.
Flutter Support
Flightloads allows simplified input across the flight envelope for M-k pair set definition and can be used to set multiple boundary conditions and M-k pair sets in a single execution. It supports PK, PKNL, K, and KE flutter eigenvalue analysis methods comprehensively.
Loads Browser/post Processing
The Flightloads UI can be leveraged to run Loads Plots and Load Summations, including automatic report generation, CSV export to spreadsheets. It can export text files of MSC Nastran FORCE Bulk Data entries for selected loads, retrieve models and loads data from the database, and browse loads on either aerodynamic or structural models.
