摘要

一架战斗机有多个燃料箱,考虑到飞机俯仰角、滚转角和加速度参数等飞行机动的各种动态影响,需要对燃料箱的燃油量进行可靠的测量。利用计算模型编制了燃油计量系统的机载程序,对燃油计量系统进行了最优估计。利用基于单片机的电子单元,采用最小二乘估计数值方法实现了燃油计量系统的计算建模。结果表明,该方法平滑了动态飞行条件下燃油量估计的波动,提高了燃油计量精度。

A real time computational model of fighter aircraft fuel gauging system
A fighter aircraft has several fuel tanks and the fuel quantity of the fuel tanks is required to be gauged reliably taking into account the various dynamic effects of flight maneuvers like aircraft pitch angle, roll angle and acceleration parameters. An onboard program for the fuel gauging system is developed using a computational model resulting in to an optimal estimate of fuel gauging system. Computational modeling of fuel gauging system is realized by using least square estimation numerical method with Microcontroller based Electronic unit. It was seen that the fluctuations in the fuel quantity estimation under the dynamic flight conditions is smoothened and the fuel gauging accuracy is improved.
