NASA Glenn Icing Research Tunnel (IRT) Testing
The NASA Glenn Icing Research Tunnel (IRT) testing is a critical service for aerospace and aviation industries, focusing on the simulation of icing conditions that aircraft may encounter during flight. This service ensures that aircraft materials, systems, and components are tested under realistic icing scenarios to evaluate their performance and durability.
The NASA Glenn IRT allows for precise control over environmental parameters such as temperature, humidity, and airflow velocity. Specimens are exposed to controlled icing environments that replicate the conditions found in high-altitude clouds, enabling engineers to assess how materials and structures behave under these challenging conditions. This testing is essential for ensuring aircraft safety, compliance with aviation regulations, and optimizing design.
The IRT can simulate a variety of icing conditions including clear ice, rime ice, mixed-phase icing, and supercooled water droplets. The facility's capabilities include the ability to generate ice accretion on specimens up to 24 inches in diameter and 18 feet long, making it suitable for testing full-scale engine nacelles or smaller components.
During a typical test, specimens are mounted inside the IRT and exposed to controlled icing conditions. Sensors measure critical parameters such as ice accretion rate, temperature, humidity, and airflow velocity. After testing, engineers analyze the data to assess material properties, structural integrity, and system performance under icing conditions.
The NASA Glenn IRT is accredited by the American Society for Testing and Materials (ASTM) and conforms to international standards such as ISO 17986-4:2015. This accreditation ensures that tests conducted in the facility meet rigorous quality control standards, providing confidence in the results.

Why It Matters
The NASA Glenn Icing Research Tunnel (IRT) testing is essential for ensuring the safety and reliability of aircraft operating in icing conditions. Ice accumulation on critical components can lead to structural failure, loss of control, or other catastrophic failures that could endanger passengers and crew.
- Reduces risks associated with ice accretion
- Ensures compliance with aviation regulations
- Improves material selection and design for cold environments
- Supports continuous improvement in aircraft performance and safety
The IRT provides a controlled environment to evaluate the effectiveness of de-icing systems, such as anti-icing coatings, boots, and electrical heating elements. By simulating real-world icing conditions, engineers can optimize these systems to ensure they perform effectively under various weather scenarios.
Testing in the NASA Glenn IRT also supports research and development efforts aimed at improving aircraft design for cold climates. Engineers can use the facility's data to refine materials and structures that are more resistant to ice accretion and easier to de-ice.
