Raptor Scientific manufactures large precision air bearings that offer ideal space simulator platforms for testing attitude control systems in satellites and cubesats. Spherical air bearings provide a cable pass-through to allow inter-connection between payloads mounted on opposite ends. Hemispherical air bearings are provided with a bolt pattern on the flat top surface. Our standard bearings […]

Understanding mass properties, such as center of gravity, makes it possible to design and build stable objects and to predict their performance in a medium such as air or water. With aircraft, the center of lift is the point where the sum total of all lift generated by parts, principally by wings, control surfaces, and […]

Measuring Weight and Center of Gravity of Large Objects and Spacecraft Measuring the center of gravity (CG) of large objects or spacecraft presents many of the typical problems associated with measuring CG of smaller objects. Some of these issues are commonly: constructing an instrument with known geometry, repeatability of said geometry under a wide array […]
