At present, the electrical system has become the first choice for military flight simulators. However, although the electric system has the above advantages, some training facilities still use the hydraulic system because the main problem involved is the payload. The effective load of hydraulic system is 38,000-40,000 pounds (17236-18143 km/km), and that of electric system is about 32,000 pounds. A payload of 32,000 pounds is enough to carry most simulators. However, industry reasons limit the implementation of this standard.
The electric system has made great progress, not only because of its long service life and environmental protection, but also because of its high sports quality. Crosstalk interference test by CAE. This test is used to determine the ability of the electrical system and hydraulic system to prevent interference signals from being generated to other machine shafts in the process of responding to the commands of one machine shaft. The crosstalk interference ability of the electrical system of j. 1Hz/command is better than that of the hydraulic system of1Hz. Therefore, the comparison between electrical system and hydraulic system is no longer based on performance comparison, but on cost.
Most military flight simulators use the electrical system of CAE company, and it is expected that more and more simulators will use the electrical system. The electrical system can improve the fidelity of the whole analog signal. At present, simulators are all new systems under construction, and more than 90% of them use electric platforms, which are used in military and civil aircraft. In 2008, Flightsafety will produce about 30 simulators equipped with electric systems and some systems equipped with electric loads but without full-motion systems, some of which will be ordered in 2009. Aircraft that have ordered electrical systems include C- 130, 7H-H, V-22 and C- 17.
