APPLICATIONS OF KRD201/301/311 NON-STANDARD CENTER OF GRAVITY, MOMENT OF INERTIA TESTER
Model Airplane Application
Satellite Momentum Wheel Application
INS (Inertial Navigation System) Application
Stable Targeting System Application
Micro Bullet Application
Inertia Tester Application
For asymmetric structures, the inertia product of the object can be measured by using the torsional pendulum method of measuring the moment of inertia.
Main technical specifications
- Rotational inertia range: 0.05 kg-㎡～0.5 kg-㎡;
- Measurement accuracy of rotational inertia: ±0.3%;
- Inertia product measurement accuracy of: ±1%;
- Principle axis of inertia measurement accuracy: ±20;
- Output parameters:
l6 central inertial tensors;
l9 direction cosines to determine where 3 principle axises of inertia are;
l3 principal moments of inertia.
Measure all six inertia tensors: Ix, Iy, Iz, Ixy, Ixz, Iyz.
For the rotational inertia tester, the fixture is horizontally installed when ly, lz, and lyz are measured, the fixture is installed at a 45° when Ixy and Ixz are measured, and the fixture is installed vertically.
There are 3 kinds of no-load situations, so it is necessary to measure the tensor under 3 kinds of no-load conditions and 6 kinds of load conditions, therefore, the measured tensors are ly under no load, lx under no load, lxy under no load, ly under load, lz under load, lyz under load, lxz under load, lxy under load, and lx under load.
