Our groundbreaking solutions offer the highest level of accuracy, safety, and exceptional product reliability. Since 1959 we have built our reputation on our exceptional products and service.

The Raptor Scientific Family:


Groundbreaking Solutions

Over the last 55 years, we have sold more moment of inertia and center of gravity instruments than any other company. We invented the force restoration concept of CG measurement and the inverted torsion pendulum method of measuring MOI and originated the spherical gas-bearing spin balance machine which uses two force transducers to determine both product of inertia and CG offset in a single run.

Product of Inertia vs. Moment of Inertia

According to Newton’s Laws, objects will stay in their current state of motion unless something acts upon them. While Newton’s Laws are usually applied to linear motion, they also apply to rotation. A rotating object will continue to rotate unless a force acts on it. How quickly an object rotates depends on its mass properties […]

Why Is Moment of Inertia Important?

Why Is Moment of Inertia Important? The moment of inertia (MOI) is one of the many mass properties that describe an object’s stability and the forces needed to alter its motion. For aerospace engineering, stability is a crucial element in designing and manufacturing air and spacecraft. Knowing the MOI about various axes is vital to determining how a device […]
