- Simple, rugged solution with long-term structural benefits
Transland’s hopper baffle is a small addition that makes a big difference — protecting your equipment and enhancing your application performance.
Hopper Baffle for Thrush Aircraft
Structural Strength. In-Flight Stability. Long-Term Protection.
Transland’s hopper baffle for Thrush aircraft is built to protect and enhance the performance of your aerial application system. Whether loading dry or liquid material, this internal reinforcement helps prevent costly damage and supports consistent in-flight behavior.
Prevent Cracking During Loading
When filling the hopper with dry granules or liquid, especially at high speed or volume, the incoming material can create significant localized force. The baffle diffuses this impact, reducing stress on the hopper’s fiberglass walls and seams. This reinforcement helps prevent cracking or fatigue, especially in demanding operations with fast-fill systems.
Reduce Material Movement During Flight
Once in the air, the baffle also minimizes shifting of dry material and sloshing of liquid. This added in-flight stability helps maintain better aircraft handling and reduces sudden load shifts during turns, pull-ups, or turbulent conditions.
