Abstract

A portable flight simulator is installed upon a conventional vehicle trailer for storage and transportation to various sites. The apparatus includes a folding video screen which when erected provides a relatively wide and long field of view for the operator of the simulator, rather than a relatively small and close video monitor display. The screen and video projector are immovably affixed to an operator cab or cockpit when the simulator apparatus is erected for operation, with cockpit movement and attached screen and projector being controlled by the operator in the cockpit. A conventional personal computer and flight simulator program provide the video signal for the projector, which projects the video program onto the screen. The operator reacts to the video program by using a control stick to control the orientation of the video program conventionally. Audio output may also be provided for realistic sound effects, or music for the operator.

Claims

1. A portable flight simulator, comprising:

a mobile trailer base having an operator cockpit installed thereon;

a video screen foldably extending from said cockpit and immovably secured thereto by a plurality of removable arms when said video screen is erected for operation, for providing a large field of view for an operator disposed within said cockpit when said video screen is erected for operation;

video projector means;

computer means communicating with said projector means for operating a video program, and a video program installed within said computer means for selectively projecting upon said screen by said projector means;

a pitch mechanism and a roll mechanism for pivotally securing said cockpit, said projector means, and said screen to said trailer base and for selectively arcuately moving said cockpit, said projector means, and said screen about corresponding pitch and roll axes;

hydraulic actuation means for said pitch mechanism and said roll mechanism; and

control means disposed within said cockpit and communicating with said computer means for controlling said video program and said hydraulic actuation means.

2. The portable flight simulator according to claim 1, wherein said control means further comprises:

a control stick disposed within said cockpit for controlling said video program;

said control stick having a base arcuately mounted to an underlying support;

a plurality of electric switches disposed beneath said control stick base; and

said switches communicating with said hydraulic actuation means for selectively actuating said pitch mechanism and said roll mechanism when said control stick and said base are correspondingly manipulated.

3. The portable flight simulator according to claim 1, wherein said video screen is selected from the group consisting of a translucent screen and an opaque screen.

4. The portable flight simulator according to claim 1, wherein said video projector means further comprises:

said video screen having a base, and said cockpit having a forward panel;

said projector means comprising a video projector disposed at said base of said screen, and projecting toward said cockpit; and

a mirror disposed at said forward panel of said cockpit and facing said screen, for reflecting video images from said projector to said screen.

5. The portable flight simulator according to claim 1, wherein:

said cockpit further includes a forward panel having an upper portion; and

at least said upper portion of said forward panel is open, for providing the operator with a view of said video screen.

6. The portable flight simulator according to claim 1, further including enclosure means foldably and removably extending from said cockpit to said video screen.

7. The portable flight simulator according to claim 1, wherein said video screen further includes:

at least an upper and a lower laterally disposed screen support;

a screen lift arm pivotally extending between said cockpit and said upper screen support; and

a screen lift strut telescopingly extending between said cockpit and said screen lift arm, for selectively raising said screen lift arm and said upper screen support for selectively erecting said video screen.

8. The portable flight simulator according to claim 7, wherein said screen lift strut is a hydraulic cylinder operating in tension.

9. The portable flight simulator according to claim 1, wherein said hydraulic actuation means for said pitch mechanism and said roll mechanism each further include a pair or hydraulic cylinders.

10. The portable flight simulator according to claim 1, wherein:

said cockpit, said projector means, and said screen have a combined center of gravity disposed forwardly and below said pitch axis and said roll axis, and;

said cockpit, said projector means, and said screen pitch and roll to a horizontal orientation when hydraulic pressure is released within said pitch mechanism and said roll mechanism.

11. A portable flight simulator, comprising:

a mobile trailer base having an operator cockpit installed thereon;

a video screen extending from said cockpit;

video projector means;

computer means communicating with said projector means for operating a video program, and a video program installed within said computer means for selectively projecting upon said screen by said projector means;

a pitch mechanism and a roll mechanism for pivotally securing said cockpit, said projector means, and said screen to said trailer base and for selectively arcuately moving said cockpit, said projector means, and said screen about corresponding pitch and roll axes;

hydraulic actuation means for said pitch mechanism and said roll mechanism; and

a control stick disposed within said cockpit for controlling said video program;

said control stick having a base arcuately mounted to an underlying support;

a plurality of electric switches disposed beneath said control stick base; and

said switches communicating with said hydraulic actuation means for selectively actuating said pitch mechanism and said roll mechanism when said control stick and said base are correspondingly manipulated.

12. The portable flight simulator according to claim 11, wherein:

said video screen foldably extends from said cockpit, and;

said video screen is immovably secured to said cockpit by a plurality of removable arms when said video screen is erected for operation, for providing a large field of view for an operator disposed within said cockpit when said video screen is erected for operation.

13. The portable flight simulator according to claim 11, wherein said video screen is selected from the group consisting of a translucent screen and an opaque screen.

14. The portable flight simulator according to claim 11, wherein said video projector means further comprises:

said video screen having a base, and said cockpit having a forward panel;

said projector means comprising a video projector disposed at said base of said screen, and projecting toward said cockpit; and

a mirror disposed at said forward panel of said cockpit and facing said screen, for reflecting video images from said projector to said screen.

15. The portable flight simulator according to claim 11, wherein:

said cockpit further includes a forward panel having an upper portion; and

at least said upper portion of said forward panel is open, for providing the operator with a view of said video screen.

16. The portable flight simulator according to claim 11, further including enclosure means foldably and removably extending from said cockpit to said video screen.

17. The portable flight simulator according to claim 11, wherein said video screen further includes:

at least an upper and a lower laterally disposed screen support;

a screen lift arm pivotally extending between said cockpit and said upper screen support; and

a screen lift strut telescopingly extending between said cockpit and said screen lift arm, for selectively raising said screen lift arm and said upper screen support for selectively erecting said video screen.

18. The portable flight simulator according to claim 17, wherein said screen lift strut is a hydraulic cylinder operating in tension.

19. The portable flight simulator according to claim 11, wherein said hydraulic actuation means for said pitch mechanism and said roll mechanism each further include a pair or hydraulic cylinders.

20. The portable flight simulator according to claim 11, wherein:

said cockpit, said projector means, and said screen have a combined center of gravity disposed forwardly and below said pitch axis and said roll axis, and;
