In this paper,the characteristic and implementation principle of OpenGL are described,and according to the requirement of air firth simulation,this paper programs 3D flight path display program by OpenGL to display 3D flight path,and realizes visual point roaming and reads the fly data of the specified point flight path.

By means of dynamics equation and kinematics equation,trajectory of flying radar targets are calculated .

In this paper,a method of target flight trajectory forecast based on α-β-γ filter is pointed out.

The relative modeling and simulation techniques include flight dynamics environment modeling and re-entry flight trajectory parameter generating, strapdown inertia sensor modeling and putout signal imitating and real-time schedule arithmetic in Hardware-in–the-Loop simulation system.

Clear projection velocity and flight trajectory of explosion fragments in chemical industry parks help to reveal the Domino effect caused by the fragments.

The reproduction of flight paths based on the data of digital flight data recorders is important to analyze flight accidents and improve pilots flying technique.

One of the basic objects of a flight path planner is to plan a route through threat space to accomplish mission objectives, at the same time the route should satisfy mission planning constraints.
