AeroTex UK have significant experience in the modelling and analysis of complex structures and loading conditions using both commercial codes such as Nastran and LS-Dyna, and bespoke, in-house produced, FE analysis tools. We have worked with aircraft primes, research organisations, under collaborative research programmes to develop complex and innovative models to address both specific static and dynamic non-linear issues as well as complex fluid structure interactions problems
Key Capabilities
Bar-Beam to Whole Helicopter
Finite Element (FE) modelling of a range of structures from simple bar-beam models to a full medium-lift helicopter
Bespoke Models
With our wide ranging experience AeroTex can create bespoke FE models for various user specific applications for a project tailored exactly to your needs.
Complex Loads
Complex load generation for application to different design cases.
Bespoke Tools
AeroTex have extensive experience in the development of complex and innovative models to address specific issues and have also been involved in linking the aeroelastics and loads through to structural optimisation software.
Mesh Generation
AeroTex staff are experienced in mesh generation, including dealing with complex geometries and incomplete CAD. We are familiar with a range of software platforms and have worked on modelling small components through to whole aircraft.
Statics to Explosions
AeroTex staff have been involved in the analysis of a wide range of cases from basic statics through to explosions.
Some Projects we have worked on:
Flutter Clearance for Rear Empennage
In providing Flutter support to an aircraft prime seeking certification, AeroTex provided advice on the analysis approach that should be used, analysed the rear empennage including variation in attachment stiffness to account for system non-linearity and provided advice to address concerns expressed by Certification Authorities.
Vibration under Aerodynamic Loading – Modifications to a Wind Tunnel
In aiding a customer to develop a new support system within their acoustic wind tunnel, AeroTex produced a digital twin, combining operational modal analysis data and the output from forced finite element models. Based on these models, a mitigation system was put in place to meet challenging customer requirements.
Rotor blade Aeroelastic Analysis – Flutter Envelope
As part of a larger research programme AeroTex conducted flutter analysis of a smart rotor blade, producing a beam representation of the blade and a separate control surface model and then strip wise aerodynamic models to account for variation in speed along the blade which could be coupled to produce a flutter envelope.
