Abstract

Claims (41)

1. A method for aircraft mission modeling and simulation performed by a computing device comprising:

selecting on the computing device an aircraft;

obtaining by the computing device performance data for the selected aircraft;

selecting on the computing device a maneuver to be performed by the aircraft;

applying by the computing device a rule to the selected maneuver to determine whether the selected aircraft is capable of performing the selected maneuver;

generating by the computing device a profile segment for the selected maneuver from the performance data when the selected aircraft is capable of performing the selected maneuver;

storing by the computing device the profile segment in a library of profile segments, wherein the library of profile segments comprises valid profile segments for the aircraft as determined by the rules;

selecting on the computing device a procedure for the aircraft to be performed, wherein the procedure executes one or more profile segments selected from the library of profile segments;

creating by the computing device an object for the procedure by assembling the one or more profile segments; and

displaying by the computing device a simulation of the aircraft performing the procedure on a display device.

2. The method of claim 1 further comprising:

generating by the computing device a two-dimensional downrange-altitude profile, wherein the two-dimensional downrange-altitude profile is formed from segments of curve shapes comprising linear, semi-circular, Bezier and integrated curve shapes; and

mapping by the computing device the two-dimensional downrange-altitude profile into three-dimensional coordinates.

3. The method of claim 2 , wherein the three-dimensional coordinates are mapped by the computing device using a Flat-Earth Coordinate System and then converted to Earth-Centered Fixed (ECF) coordinates using an algorithm.

4. The method of claim 1 , wherein the procedure is selected from the group consisting of acceleration, takeoff, landing, climb, descent, cruise, terrain following, and vertical takeoff and landing.

5. The method of claim 1 , wherein creating by the computing device an object for the procedure by assembling the one or more profile segments comprises creating by the computing device an object for the procedure by assembling the one or more profile segments relative to a reference point.

6. The method of claim 5 , wherein the reference point is selected from the group consisting of waypoints, runways, aircraft carriers, other aircraft in formation, and aerial tankers.

7. The method of claim 1 further comprising the computing device performing the method using a matrix application.

8. The method of claim 7 , wherein the matrix application uses a catalog structure for the loading and saving of aircraft, performance data, reference points, rules, and profile segments.

9. A system for aircraft mission modeling comprising:

a computing device;

a display;

software instructions, wherein the computing device is configured with the software instructions to cause the computing device to perform operations comprising:

selecting an aircraft;

obtaining performance data for the selected aircraft;

selecting a maneuver to be performed by the aircraft;

applying a rule to the selected maneuver to determine whether the selected aircraft is capable of performing the selected maneuver;

generating a profile segment for the selected maneuver from the performance data when the selected aircraft is capable of performing the selected maneuver;

storing the profile segment in a library of profile segments, wherein the library of profile segments comprises valid profile segments for the aircraft as determined by the rules;

selecting a procedure for the aircraft to be performed, wherein the procedure executes one or more profile segments selected from the library of profile segments;

creating an object for the procedure by assembling the one or more profile segments; and

displaying a simulation of the aircraft performing the procedure on the display.

10. The system of claim 9 wherein the computing device is further configured with software instructions to cause the computing device to perform operations comprising:

generating a two-dimensional downrange-altitude profile, wherein the two-dimensional downrange-altitude profile is formed from segments of curve shapes comprising linear, semi-circular, Bezier and integrated curve shapes; and

mapping the two-dimensional downrange-altitude profile into three-dimensional coordinates.

11. The method of claim 10 , wherein the three-dimensional coordinates are mapped by the computing device using a Flat-Earth Coordinate System and then converted to Earth-Centered Fixed (ECF) coordinates using an algorithm.

12. The system of claim 9 , wherein the procedure is selected from the group consisting of acceleration, takeoff, landing, climb, descent, cruise, terrain following, and vertical take off and landing.

13. The system of claim 9 , wherein creating an object for the procedure by assembling the one or more profile segments comprises creating an object for the procedure by assembling the one or more profile segments relative to a reference point.

14. The system of claim 13 , wherein the reference point is selected from the group consisting of waypoints, runways, aircraft carriers, other aircraft in formation, and aerial tankers.

15. The system of claim 9 wherein the computing device is further configured with software instructions to cause the computing device to perform operations using a matrix application.
