Abstract :
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.
