Moment of Inertia Instruments

Two Plane Spin Balance Machines with MOI Capability POI7000 Dynamic Balance Understanding the moment of inertia (MOI) is essential for engineers and program managers in aerospace, defense and advanced manufacturing industries. Raptor Scientific offers an extensive selection of industry-leading MOI instruments, designed to deliver accurate, repeatable results for research and development and production environments.

The Critical Role of Moment of Inertia Measurement

While the moment of inertia (MOI) for simple objects can be calculated fairly accurately using well-known formulas, real-world components are rarely as simple. For complex or irregular objects, modeling and summing individual MOIs introduces significant errors due to dimensions and material density uncertainties. Direct moment of inertia measurement with dedicated MOI measurement devices removes these uncertainties, providing faster, more reliable results and supporting critical safety, performance and compliance requirements.

MOI Measurement Devices Available From Raptor Scientific

Raptor Scientific offers a comprehensive range of instruments to measure moment of inertia, from devices capable of measuring tiny components weighing less than 1 gram to systems designed for large assemblies up to 10,000 kilograms (22,000 pounds). Many of our MOI instruments also integrate weight and center of gravity measurements, providing a complete mass properties solution. Our MOI measurement devices use advanced technologies and digital integration for efficient, automated testing, supporting various object shapes and sizes for OEM manufacturers and MRO providers. Our selection of MOI instruments includes:
  • Aircraft Control Surface for MOI Testing: This gravity-driven pendulum system measures the moment of inertia of aircraft control surfaces up to 500 pounds (225 kilograms) and delivers accurate results regardless of altitude, temperature or humidity.
  • XKR Moment of Inertia (Small-Payload): This series of precision devices is dedicated to small payloads, providing measurement accuracies better than 0.1% for objects up to 5 pounds.
  • XR Moment of Inertia Production series: The XR series consists of versatile instruments designed to measure the MOI of objects up to 250 pounds (120 kilograms), regardless of size or shape, with 0.25% accuracy.
  • GB High-Accuracy Moment of Inertia series: Engineered for large mechanical components up to 15,000 pounds (6,800 kilograms), the GB series achieves ±0.1% accuracy — ideal for spacecraft, automotive engine parts, re-entry vehicles and complex assemblies.
