Full-Scale Precision Measurement

Challenge

Aerospace manufacturing deals with widely varying materials such as carbon fiber composites (CFRP) and titanium alloys. Components often feature freeform and thin-walled structures (e.g., wing skins as thin as 0.5 mm), leading to interlayer aperture deviations and deformation challenges during processing and inspection. Extreme precision is required at micron-level tolerances under harsh conditions, including temperatures above 1600℃, tens of thousands of RPM, and vacuum cryogenic environments down to -180℃. Even minor surface deviations can cause thrust loss and structural risks. The size range spans from tiny film cooling holes to wing and fuselage sections measuring tens of meters, demanding highly adaptable measurement systems.

Industry Pain Points

Diverse Material Characteristics:
Extensive use of special materials such as carbon fiber reinforced polymers (CFRP) and titanium alloys, with many components featuring free-form surfaces and thin walls (e.g., wing skin as thin as 0.5mm), leading to processing and inspection challenges like interlayer aperture deviations and deformation.

Extreme Precision and Operating Conditions:
Critical components require micrometer-level tolerances and must maintain stability under extreme environments including temperatures above 1600℃, rotational speeds of tens of thousands of RPM, and vacuum cryogenic conditions down to -180℃. Even slight surface deviations can cause thrust loss and structural risks.

Large Dimensional Range:
Inspection targets range from microscopic film cooling holes to wing and fuselage sections measuring tens of meters, necessitating measurement systems with strong scale adaptability.

Customer Requirements

Full-Scale Measurement Capability:
Achieving precise measurement across the entire range from micro-nano scales to large macro dimensions, with stable data acquisition supported even in complex environments.

Balance of Accuracy and Efficiency:
Significantly improving inspection efficiency while maintaining micrometer-level measurement accuracy to meet batch production consistency requirements.

Full-Process Quality Traceability:
Establishing a quality data chain covering from raw materials to final assembly delivery, enabling real-time data collection, intelligent analysis, and complete traceability.

Limitations of Existing Measurement Solutions

Imbalance Between Measurement Efficiency and Accuracy:
When dealing with complex surfaces and special materials, measurement speed and accuracy cannot be balanced, resulting in incomplete detail capture.

Poor Adaptability to Special Structures:
Insufficient measurement adaptability for composite materials and weak-rigidity thin-walled parts, with traditional contact measurement methods prone to causing interlayer delamination.

Weak System Integration Capability:
Limited large-scale measurement capacity and inconsistent data standards across multiple devices make it difficult to build a complete measurement-analysis-feedback closed loop.
