Semi-Rigid Recoil Measurement Architecture
The UMPIRE Static platform is designed as a semi-rigid system that preserves the natural recoil load path while allowing controlled rearward motion. This enables accurate evaluation of recoil pad compliance and partial energy dissipation through the stock interface and muzzle devices, without introducing variability from human interaction.
Quantification of Recoil Mitigation Components
Ideal for comparative testing of recoil pads, muzzle brakes, and other mitigation devices. The system isolates component-level effects while maintaining consistent boundary conditions, allowing meaningful performance comparisons across configurations.
Sliding and Rigid Test Configurations
Supports both sliding and rigid configurations. The sliding mode allows controlled displacement for evaluating compliance and energy absorption, while the rigid mode constrains the rifle to the fixture for measuring system response without rear pad deformation.
Modular Rear Interface with Custom Adapter Support
Accommodates a wide range of rifle and shotgun platforms through interchangeable, 3D-printable stock adapter cups. Custom-fit interfaces ensure consistent load transfer and alignment across test articles.
Adjustable, Constrained Front Rest Assembly
Multiple restraint methods, including threaded clamps and straps, allow secure fixturing of diverse fore-end geometries while maintaining smooth, repeatable motion during recoil.
Precision Alignment and Preload Control
Fine vertical adjustment and dual preload sliders ensure proper alignment with the recoil axis and consistent contact with the load cell, improving repeatability across test sequences.
Built for Controlled, Repeatable Testing
Engineered for durability and consistency under repeated firing cycles, including heavy recoiling platforms, in laboratory and range environments.
