Introduction
In the dynamic world of aerospace assembly, precision and efficiency are paramount. Delta Sigma has revolutionized the process by introducing an automated RCS measurement system for In-Process Verification (IPV) and final component validation. This groundbreaking technology not only enhances accuracy but also streamlines the production line, making it accessible even to technicians with minimal experience.
The Turnkey RCS Measurement System
Delta Sigma’s turnkey RCS measurement system is a comprehensive solution that includes radar, antennas, shroud, ogive pylon, foam column, elevators, automated pit covers, test bodies, target transport carts, and calibration targets. The entire system operates seamlessly, automatically loading test objects onto the correct target support system without any manual intervention.
User-Friendly Interface
The user interface is designed for production line workers, eliminating the need for experienced RCS test engineers. With simple pass/fail indicators displayed to technicians, the detailed dataset is stored for engineering review and analysis. A wall display guides users through the test sequence, making the operation intuitive and efficient.
Key Factors for Adding Production Line IPV
1. “No Experience Necessary”
The system allows production line technicians to make RCS measurements, ensuring consistency regardless of the operator’s experience level.
2. High Reliability
In the relentless production grind, there is no time for troubleshooting or repairs. The automated system ensures high reliability and minimizes downtime.
3. Speed
Testing every part must be swift to surpass the existing failure rate repair time. The automated process significantly reduces measurement and overhead time.
Why Use In-Process Verification (IPV)?
1. Finding Problems Early
Detecting issues during the production process minimizes costs and makes repairs more manageable.
2. Minor Process Changes
Identifying small changes in RCS before they become problems, such as variations due to personnel changes or machine wear.
3. Components Assurance
Ensuring components are known to be of high quality before being applied to aircraft, enhancing overall reliability.
Chamber Planning by Delta Sigma Company
Delta Sigma offers comprehensive chamber planning services, covering design aspects such as chamber design, antenna design, shroud design, radar design, pylon, column, and rotator designs, elevator and tilt mechanism, pit cover designs, and integrated system control and data processing software.
Automated RCS Measurement Systems by Delta Sigma
Delta Sigma’s expertise lies in designing and building automated RCS measurement systems, requiring just a single button push for a seamless process:
- Chamber door opens
- Automatic target loading
- Chamber door closes
- Data collection of all frequencies, polarizations, LDA’s, and AZ angles
- Real-time data processing and comparison to standards
- Display of pass/fail to the operator
- Automatic target unloading
User Skill Requirements in Production Line Measurements
While user skills are still needed for attaching items under test to the fixture, the system ensures that even a tech starting last week can operate it effectively. Engineering skills come into play only if a failure occurs, minimizing the need for specialized expertise in the test chamber.
Automatic Target Support Selection and Loading
The system intelligently auto-selects the correct target support based on the part being tested. The user pushes a cart with a loaded test fixture to the chamber, guided by air bearings, making the process effortless. The cart aligns properly with the pit covers, ensuring accurate positioning. The automatic engagement and locking of the target are carried out with minimal effort from the operator.
Data Collection and Processing
Once in position, the radar initiates data collection of all azimuth and elevation angles and target motion with a single button push. Real-time data processing generates a 2D ISAR image, allowing for immediate analysis. Pass/fail is determined for various criteria, providing a wealth of information for RCS diagnostics.
Conclusion
Delta Sigma’s Automated RCS Measurement System for High-Speed Production Line In-Process Verification represents a leap forward in aerospace assembly. The integration of automation not only enhances precision and repeatability but also empowers production line technicians, making RCS measurements accessible to all skill levels.
