The Phasight X Series handheld 3D scanner from Beijing AIXUNFEI Technology Co., Ltd. provides metrology-grade accuracy and multiple scanning modes. It delivers clear application value across aerospace product design, manufacturing, and maintenance.
This article analyzes the technical features and application scenarios of the Phasight X Series in the aerospace industry.
1. Product Design and Reverse Engineering
Aerospace products have highly complex structures. A single aircraft may contain hundreds of thousands to millions of components, and manufacturing accuracy is directly related to flight safety.
During product development and modification, accurate geometric data is the foundation for subsequent design and engineering work.

With non-contact measurement technology, the Phasight X Series handheld 3D scanner can quickly capture complete shape data of aircraft bodies and components.
The scanner offers accuracy up to 0.02 mm and resolution up to 0.01 mm. For complex curved surfaces such as aircraft fuselages and wings, traditional surveying methods often struggle to achieve full coverage. A handheld 3D scanner can complete the acquisition of full-shape data within a shorter time while accurately restoring surface details.
The scanned data can be exported in multiple formats, including ASC, IGS, TXT, UMK, STL, PLY, and OBJ. After being imported into professional software, the data can be used to generate CAD models, providing a reliable data foundation for secondary development and design improvement of aircraft and components.

In civil aviation maintenance, some aviation technology companies have introduced handheld 3D scanners to comprehensively measure key components such as cockpit seat rails. The acquired 3D data has been used for new product design and modification, supporting the development of domestic replacement products with strong performance and controlled cost.
With its precise and reliable optical system, the Phasight X Series can maintain highly consistent measurement accuracy after repeated measurements, meeting the strict data consistency requirements of aerospace component surveying and mapping.
2. Virtual Assembly and Dimensional Verification
In aerospace product assembly, the fitting accuracy between components directly affects overall aircraft performance.
The 3D data captured by handheld 3D scanners can be used for virtual assembly. Through 3D visualization and spatial interaction in the design and manufacturing process, engineers can use manufacturing data to drive design, verify assembly accuracy, and identify potential assembly problems in advance.

When customized components are integrated inside aircraft structures with limited space, the new parts must fit surrounding structures precisely after installation. Even a small deviation may affect overall function.
The Phasight X Series provides three scanning modes:
Cross fast scanning for efficient large-area data capture.
Parallel fine scanning for high-detail surface acquisition.
Single-line deep hole scanning for narrow or hard-to-reach areas.
Users can switch modes freely according to the geometry of the scanning object.
The single-line deep hole scanning mode is designed for deep holes, grooves, and other difficult-to-access features. It can accurately capture surrounding surface morphology and geometric data of wiring areas in actual installation environments.
The collected dimensional data can be directly transferred to CAD software in parametric form, making it easier for engineers to perform feature-based modeling and design modification.
3. Component Quality Inspection and Full-Dimensional Control
Aerospace component manufacturing requires extremely high dimensional accuracy. Handheld 3D scanners play an important role in quality inspection.
For critical parts such as engine blades and turbine disks, the Phasight X Series can support scanning inspection throughout the component lifecycle.
Its scanning speed can reach up to 8.6 million points per second, and the large-area scanning range can reach 1200 mm × 1100 mm, allowing large surface data to be captured in a single scan.

Combined with professional analysis software, the scanner can accurately obtain the geometry of each blade. The installation condition of mechanical fasteners on aircraft skin surfaces can also be measured through non-contact scanning, enabling efficient inspection of large numbers of fasteners and generating comprehensive visual inspection reports.
For aerospace parts with high-precision hole spacing requirements, reflective surfaces, curved corner radii, and other measurement challenges, the Phasight X Series provides strong data acquisition capability on shiny surfaces. In fine scanning mode, seven high-precision parallel laser lines can accurately capture complex surfaces and fine details.
After comparing the scanned 3D data with the original digital model, the software can generate real-time reports that clearly show deviation distribution.
The volumetric accuracy reaches 0.015 mm + 0.03 mm/m. With the scale bar version, it can reach 0.015 mm + 0.015 mm/m, meeting the accuracy requirements of full-dimensional control in aerospace manufacturing.
4. Maintenance, Repair, and Damage Assessment
Handheld 3D scanners also provide significant value in aircraft line maintenance and overhaul.
Dents and holes caused by bird strikes or foreign object impact are among the most common types of surface damage during flight. After an aircraft arrives at the airport, damaged areas must be technically evaluated to determine whether the aircraft can continue flying safely.
Traditional methods often rely on manually drawing grids and calculating dimensions, which is inefficient and may produce inconsistent results between operators.
With the Phasight X Series handheld 3D scanner, a single operator can freely scan dense dent areas. In high-speed scanning mode, dozens of crossed laser lines enable efficient data capture.
Based on the scanned data, professional software can fit the surrounding curved surface or compare the result with the original digital model. It can automatically detect dent depth and width and generate visual inspection reports, helping engineers quickly determine whether the damage exceeds limits and significantly reducing aircraft downtime.

The Phasight X Series can also be used in aircraft wear analysis and repair inspection.
By comparing 3D information before and after aircraft use, engineers can visually observe deformation levels and obtain accurate data for maintenance, repair, and component improvement.
The scanner operates within a temperature range of -10°C to 40°C, making it suitable for hangars, field maintenance, and various on-site working environments.
5. Operational Efficiency and On-Site Deployment Advantages
The Phasight X Series is designed for convenient deployment in aerospace inspection scenarios.

The device is equipped with a standard magnetic ring screen interface. Users can directly attach an external screen to the magnetic position and observe scanning progress in real time. This eliminates the need to move repeatedly between the scanner and a computer, allowing one operator to complete both data acquisition and quality monitoring.
An optional wireless connection module uses an ultra-high-speed wireless transmission chip, removing the limitation of cable connections and allowing a wider scanning range. Combined with high-density battery power, it is suitable for large-area mobile scanning in hangars or emergency field inspection.
For data output, the device supports a USB 3.0 interface, enabling standardized and efficient export and processing of scan data. It can also be integrated with many third-party measurement software platforms and automation systems to generate inspection reports that meet industry standards.
The scanner uses Class II laser, which is safe for human eyes and meets on-site operational safety requirements.
Expanding the Role of 3D Scanning in Aerospace
The application of handheld 3D scanners in aerospace now covers product design, reverse engineering, virtual assembly, component inspection, maintenance, repair, and damage assessment.
With the rapid development of aircraft manufacturing and the continued delivery of domestically produced large aircraft, the depth and breadth of handheld 3D scanning technology across the full aerospace product lifecycle are expected to expand further.
Beijing AIXUNFEI Technology Co., Ltd. will continue to provide accurate, portable, and practical 3D scanning solutions for aerospace manufacturing, inspection, and maintenance applications.
