NDT Inspection and Measurement for Aerospace

Non-destructive testing, or NDT, is the process of inspecting and measuring aerospace materials without causing any damage. In contrast to destructive testing methods, which cut, grind, or drill into materials to identify flaws, NDT uses various techniques to detect defects and irregularities without altering the material. NDT inspection is vital for the aerospace industry as it helps to ensure the safety and quality of aircraft parts and components. Scantech provides NDT inspections for airplane parts including engine parts, fuselage, fasteners on the airplane skin, and aircraft wings
Inspection of Engine Parts

The failure of a critical engine part can result in catastrophic and often fatal consequences. For this reason, aviation engine parts are subject to rigorous inspection procedures prior to each and every flight. In order to ensure that these parts meet the required safety standards, inspectors must have a comprehensive understanding of the many different components that make up an aircraft engine. Scantech’s 3D scanners allow thorough inspection of engine parts throughout their entire life cycle. Our 3D scanners efficiently inspect all kinds of standard geometries for each blade. Innovative algorithms in our 3D software ScanViewer ensure the correct computation of standard geometries.

Fuselage Measurement
Fuselage Measurement

Fuselage measurement is an important aspect of aircraft design. The fuselage width and shape play a critical role in the jet’s aerodynamics, affecting everything from fuel efficiency to stability in flight. In order to ensure that the jet meets all safety and performance requirements, engineers must perform accurate measurements of the fuselage during every stage of development. While tedious and painstaking work, it is crucial for producing a high-quality product. With the help of our cutting-edge 3D technologies, Scantech provides reliable and cost-effective 3D digital solutions to obtain fuselage data. Our fast data acquisition allows interior components of aircraft to be accurately measured to check their matching to the fuselage.

Measurement of Fasteners on the Airplane Skins

Fasteners are used for joining aircraft skin, rib and spar sections. It is important for holding sections in place for securing fittings to various parts of the aircraft. Common fasteners include anchors, locking bolts, hex bolts and pins. Due to their ability to withstand extreme stress without breaking or otherwise succumbing to damage, fasteners are safe and effective way for aerospace manufacturing companies to build aircraft. Scantech’s handheld 3D laser scanners suit well for inspecting sub-flush conditions of all fasteners installed on the exterior surfaces of airplanes. Aviation OEMs and suppliers use our non-contact and ultra-fast 3D measurement to measure a large number of fasteners to check their depth and flush.

Aircraft Wing Inspection

Aircraft wing is a framework made up of spars and ribs and covered with metal. It is shaped to make air move faster over the wing. When airplane is in flight, the pressures on the top and bottom of the wing are different. It makes the aircraft wing subject to risks of deformation. The deformation of in-flight wings can significantly impact the aerodynamic performance of an aircraft, which can not be inspected and qualified intuitively. Scantech’s metrology-grade 3D scanners can obtain accurate parameters like width, length, and depth of the defect for accurate inspection.

Altair Simulation Analysis

Moving to Certification by Analysis

Modern tools: Aircraft manufacturers and suppliers are striving to speed up the aircraft certification process, which is primarily based on physical tests. Many efforts for achieving certification by analysis have been constrained by legacy analysis tools and processes. The intuitive user experience and integrated solution workflows of Altair® HyperWorks® are bringing increased efficiency to the certification by analysis processes across the industry. Altair® OptiStruct® includes an enhanced proprietary version of NASTRAN that is used in virtually every industry. OptiStruct provides solvers for linear, nonlinear, vibrations, acoustics, fatigue, heat transfer, and multiphysics analyses.

Analysis Report Automation: Creating detailed stress reports can be time consuming and repetitive, taking up valuable engineering time better spent interpreting and understanding simulation results. Process automation can decrease report generation and update time by up to 80 percent. The HyperWorks automated reporting workflow ensures all reports are assembled with a standard structure and format for the model description, model verification, and results presentation.

FOptimization and Minimum Weight DesignsF: OptiStruct is the original topology optimization structural design tool. To reduce product development time, organizations need to use simulation and optimization to drive designs rather than validate them. To achieve this, we empower engineers to apply simulation and optimization up-front in the design cycle with tools such as Altair® Inspire™ and Altair® SimSolid®. These tools support the analysis, optimization, manufacturing checks, and geometry editing functions required to power fast design iterations and decision making early.

Advanced Simulation and Analysis

Composite Design: OptiStruct is widely used for the design and optimization of laminate composites. It delivers optimal ply shapes, the optimal number of plies, and the optimal stacking sequence, while observing manufacturing constraints. Altair® Multiscale Designer® provides accurate and efficient simulation of materials and parts manufactured with continuous and chopped fibers, honeycomb cores, lattice structures, and more.

Mechanism Simulation: Altair® MotionSolve® provides a multibody integrated solution to analyze and improve mechanical system performance. MotionSolve® simulates dynamic systems including ground aircraft operation (taxi, takeoff, landing, braking, and rejected take-off), landing gear retraction and evaluation of gear forces, flap mechanism, flight control and dynamics, door opening mechanisms, helicopter design, satellite control, and packaging study of seats.

Propulsion Development: OptiStruct supports rotor dynamics solutions including rotor effect, mode tracking, and rotor energy from complex eigenvalue analysis. In addition, it provides comprehensive physics for nonlinear analysis and durability, including solutions for heat transfer, bolt and gasket modeling, hyperelastic materials, and efficient contacts.

Understanding System Interactions

Multiphysics Simulation: Altair provides multiphysics-enabled software to enable a wide range of interacting physical models to fully describe a system’s mechanical, electromagnetic, and aerodynamic performance. For example, the air pressure field during flight on a radome can be simulated with Altair® AcuSolve®, a computational fluid dynamics (CFD) solver. The pressures can then be mapped onto an OptiStruct model to accurately predict the structural response of the radome under aerodynamic load.

Antenna Design and Placement: More airborne radio equipment is being installed on aircraft. Typically, an aircraft is equipped with dozens of systems – weather radars, communication and navigation systems, surveillance, and air traffic control equipment – requiring multiple and different antennas types working at different frequency bands. The performance of an antenna is influenced by the structure it is mounted on. Altair® Feko® enables optimization of antenna design and placement for system integration.

Electromagnetic Compatibility: Electromagnetic compatibility (EMC) ensures the safe operation of an aircraft by verifying conformance with EMC immunity and emission standards. Feko can simulate important EMC criteria including antenna coupling to ensure radio system performance and sensitivity to high-power radio signals from external systems called high-intensity radiated fields (HIRF). Simulation guides design decision to mitigate HIRF effects that can induce electromagnetic fields around equipment or high frequency currents on cables leading to a degradation of equipment performance.
