S-E-A is a long-time leader in vehicle testing & safety and custom engineering solutions for the transportation industry. Our Vehicle Inertia Measurement Facility (VIMF) is the premier, state-of-the-art system for measuring mass, center of gravity (CG), and inertia properties for a broad range of vehicle types.

2018年4月9日 · We start by measuring the hub heights (RF and RR in the formula below) and weighing the car on level ground (W). Knowing the wheelbase (ℓ) and weight distribution, we can calculate the longitudinal...

In simple terms, the center of gravity is the balance point of an object, also expressed as the point where all the mass appears to be located. It’s a theoretical point at which the total weight of an object is thought to be concentrated.

Make us your first choice for device testing, microbiological analysis, regulatory testing, environmental monitoring and water testing. Expedited services are available. We package, sterilize, test, validate and perform shelf-life studies providing an end-to-end solution that gets your device on the market quickly.

2018年6月20日 · in flight CG tests are really measuring your effective elevator trim. If you're nose heavy the tail must have up trim to push the tail down/nose up. So a simple visual inspection of your elevator angle will say something about your CG. Not the total answer because horizonal stabilizer angle (decalage) may play a role too.

2014年5月2日 · Calculated globulin (CG) is derived from the difference between total protein and albumin results, and forms part of the liver function test (LFT) profile. CG is used widely in primary and secondary care to detect high levels that may indicate haematological malignancy, such as multiple myeloma.

Automotive Testing Systems to help with OEMs with Design Validation, Homologations tests, for automotive component testing, assembly testing with over 120+ solutions

2020年1月25日 · CG is probably the most important setting to get right for a good first flight. I'm using a glider in the video, but the scales will work with any small electric plane. Here are the files to print out, and a short video of how to use them.

2010年8月23日 · For 3D and sport aerobats, the easiest way to determine if the CG is correct is to fly level at a moderate throttle application. If it flies level with zero elevator input, and with the elevator neutral, then roll inverted.
