Spring 2017 Newsletter – Measuring Center of Buoyancy

Center-of-Buoyancy
August 11, 2017

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 […]

Summer 2017 Newsletter – Weight and CG of Large Objects and Spacecraft

Boeing CST-100 Starliner Weight and CG of Large Objects and Spacecraft

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 […]

Winter 2018 Newsletter – The Spacecraft Positioner: A New Fixture for Determining All Mass Properties of a Spacecraft Without Spinning

Space Craft positioner
August 11, 2018

Spacecraft are frequently moved and reoriented during assembly and ground testing, bringing with each move the risk of physical damage. During mass properties testing, a spacecraft will typically be oriented vertically and horizontally as well as rolled horizontally to obtain moment of inertia about the three axes. When product of inertia has to be determined, […]

Winter 2019 Newsletter – Benefits of Adding Weight Correction Software and Drive/Read to Your Gimbal Balance Station

February 11, 2019

When measuring a gimbal’s unbalance, the results are compared to a set tolerance. If the unbalance exceeds the amount allowed, it must be corrected. Correction is done by adding, moving, or removing ballast weight, and then measuring again. This becomes a time-consuming iterative process. Space Electronics Weight Correction Software automatically calculates a balance correction solution […]

Spring 2019 Newsletter – Benefits of Mass Property Measurements of Helmets and VR Goggles

Model KSR330 with headform fixture
August 11, 2019

Advancements in helmet-mounted electronics and VR goggles create larger and heavier head-mounted devices. Measuring and controlling the mass properties of head-mounted devices is critical to avoiding head, neck and spine injuries. Raptor Scientific is working with government and industry leaders to develop the best fixturing solutions for CG and MOI measurement while maintaining high accuracy. […]

Summer 2019 Newsletter – New Gimbal Measurement & Balance Solutions

Raptor Scientifics is launching a new version of our gimbal balance software to add several features designed to make gimbal balancing easier and faster. In the past, 3-axis gimbal balance software required two of the axes to be collinear in order to measure and balance a gimbal in a single set-up. Non-collinear 3-axis gimbals required […]

Fall 2019 Newsletter – The Importance of Understanding Mass Properties for Hypersonics and Missile Technology

Hypersonics

The extreme velocities and maneuvering accelerations of hypersonic vehicle flight profiles require that the mass properties of these type of objects are well-known and not just simply calculated. Any error or uncertainty can result in a failed mission. Given the national strategic importance, and the correspondingly rapid development rate of hypersonics, Space Electronics is well […]
