A high-precision angular accelerometer based on molecular-electronic transfer (MET) technology with a high dynamic range and a low level of self-noise has been developed. Its difference from the analogues is in the use of liquid (electrolyte) as the inertial mass and the use of negative feedback based on the magnetohydrodynamic effect. This article reports on the development of the angular molecular-electronic accelerometer with a magnetohydrodynamic cell for the creation of negative feedback, and the optimization of electronics for the creation of a feedback signal. The main characteristics of the angular accelerometer, such as amplitude-frequency characteristics, self-noise and Allan variance were experimentally measured. The obtained output parameters were compared to its analogues and it showed perspectives for further development in this field.
一种基于分子电子转移（MET）技术、具有高动态范围和低自噪声水平的高精度角加速度计已被研制出来。它与同类产品的不同之处在于使用液体（电解质）作为惯性质量，并利用基于磁流体动力学效应的负反馈。本文报道了带有用于产生负反馈的磁流体动力学单元的角分子电子加速度计的研制，以及用于产生反馈信号的电子设备的优化。对角加速度计的主要特性，如幅频特性、自噪声和阿伦方差进行了实验测量。将获得的输出参数与其同类产品进行了比较，结果显示了该领域进一步发展的前景。
