The team used simulation tools to show it was possible to achieve over-land flight by dramatically lowering the level of sonic booms through the use of an "inverted-V" engine-under wing configuration.

Namely, using the centralized and distributed database design optimizes the configuration of simulation database of Air fleet fighting dis system and reduces network flux.

A system configuration of helicopter simulation is given and a mathematical model of helicopter hovering is set up as to development helicopter simulating system in Marine search and rescue simulator.
