航空喷气燃料RP-3运动粘度特性研究

Kinematic viscosity characteristics of aviation jet fuel RP-3

采用振动弦法,在相同温度不同压力和相同压力不同温度条件下开展航空喷气燃料RP-3的运动粘度特性试验,研究航空喷气燃料运动粘度随温度和压力的变化规律。结果表明:随着温度的增大,喷气燃料RP-3的运动粘度逐渐变小,低温条件下更为明显。随着压力的增大,喷气燃料运动粘度缓慢增加,压力对喷气燃料运动粘度的影响较小。

In this study,we adopted the vibrating wire method,and carried out tests on the kinematic viscosity characteristics of aviation jet fuel RP-3 under different temperature and pressure,so as to understand the change rules of the kinematic viscosity of RP-3 with temperature and pressure.It was found that the kinematic viscosity of RP-3 decreased with the rising of temperature,especially under low-temperature condition;the kinematic viscosity of RP-3 increased with the rising of pressure,yet the pressure had relatively small effect on the kinematic viscosity of RP-3.
