Abstract

A system for moving first and second fuselage structures into assembly alignment, the system including a first transmitter indexed to a first seat track of the first fuselage structure, a first reflector target indexed to a first seat track of the second fuselage structure, a second transmitter indexed to a second seat track of the first fuselage structure, a second reflector target indexed to a second seat track of the second fuselage structure, wherein the first and second transmitters and the first and second reflector targets cooperate to provide first and second measurements indicative of position of the first fuselage structure relative to the second fuselage structure, and a manipulator system including at least one assembly actuator coupled to the first fuselage structure to move the first fuselage structure into assembly alignment with the second fuselage structure based upon the first and second measurements.

First claim

What is claimed is:

1. A system for moving a first fuselage structure and a second fuselage structure of an aerospace vehicle into assembly alignment, the system comprising:
a first transmitter coupled to the first fuselage structure and indexed to a first seat track of the first fuselage structure;
a first reflector target coupled to the second fuselage structure and indexed to a first seat track of the second fuselage structure, wherein the first transmitter and the first reflector target cooperate to provide a first measurement indicative of position of the first fuselage structure relative to the second fuselage structure;
a second transmitter coupled to the first fuselage structure and indexed to a second seat track of the first fuselage structure;
a second reflector target coupled to the second fuselage structure and indexed to a second seat track of the second fuselage structure, wherein the second transmitter and the second reflector target cooperate to provide a second measurement indicative of position of the first fuselage structure relative to the second fuselage structure; and
a manipulator system including at least one assembly actuator coupled to the first fuselage structure to move the first fuselage structure into assembly alignment with the second fuselage structure based upon the first measurement provided by the first transmitter and the first reflector target and the second measurement provided by the second transmitter and the second reflector target.

2. The system of claim 1 further comprising:
a third transmitter coupled to the first fuselage structure and indexed to another part of the first fuselage structure; and
a third reflector target coupled to the second fuselage structure and indexed to another part of the second fuselage structure, wherein the third transmitter and the third reflector target cooperate to provide a third measurement indicative of position of the first fuselage structure relative to the second fuselage structure.

3. The system of claim 2 wherein the manipulator system including the at least one assembly actuator is responsive to the first measurement, the second measurement, and the third measurement to move the first fuselage structure into assembly alignment with the second fuselage structure.

4. The system of claim 1 wherein the manipulator system including the at least one assembly actuator includes first and second assembly actuators coupled to the first fuselage structure.

5. The system of claim 1 further comprising:
a data storage unit;
an alignment application program stored on the data storage unit; and
a controller configured to execute instructions of the alignment application program to provide control signals to the manipulator system including the at least one assembly actuator to move the first fuselage structure into assembly alignment with the second fuselage structure.

6. The system of claim 5 wherein (i) the data storage unit is further configured to store a waterline axis tolerance limit, a buttline axis tolerance limit, and a fuselage station tolerance limit, and (ii) the controller is further configured to calculate an amount of movement of the first fuselage structure relative to the second fuselage structure based upon the waterline axis tolerance limit, the buttline axis tolerance limit, and the fuselage station tolerance limit.

7. A system for moving a first fuselage structure and a second fuselage structure of an aerospace vehicle into assembly alignment, the system comprising:
a manipulator system including at least one assembly actuator for independently supporting and moving the first fuselage structure into assembly alignment with the second fuselage structure; and
a measurement system independent of the manipulator system for determining position of the first fuselage structure relative to the second fuselage structure while the first and second fuselage structures are supported on the manipulator system, wherein each of the first fuselage structure and the second fuselage structure includes a plurality of seat tracks assembled thereon, the seat tracks of the first fuselage structure and the second fuselage structure being longitudinally aligned when the first fuselage structure and second fuselage structure are aligned for coupling, the measurement system including:
a first transmitter and a second transmitter arranged on the first fuselage structure, the first transmitter being indexed to a first seat track of the first fuselage structure and the second transmitter being indexed to a second seat track of the first fuselage structure; and
a first reflector target associated with the first transmitter and a second reflector target associated with the second transmitter, the first reflector target being indexed with a first seat track of the second fuselage structure and the second reflector target being indexed to a second seat track of the second fuselage structure, wherein the first seat track of the first fuselage structure is aligned with the first seat track of the second fuselage structure and the second seat track of the first fuselage structure is aligned with the second seat track of the second fuselage structure when the first and second fuselage structures are aligned and coupled together.

8. The system of claim 7 wherein each of the first and second transmitters includes a laser designator.

9. The system of claim 8 wherein each of the first and second transmitters is associated with an infrared range finder for measuring distance between the first fuselage structure and the second fuselage structure.

10. The system of claim 7 further comprising:
a computer system responsive to measurements from the measurement system and for (i) determining the position of the first fuselage structure relative to the second fuselage structure, and (ii) controlling the manipulator system to bring the first fuselage structure into assembly alignment with the second fuselage structure.

11. The system of claim 7 wherein each of the first and second transmitters provides positioning information for determining the positions of the first fuselage structure relative to the second fuselage structure to allow an operator to actuate the manipulator system to bring the first fuselage structure into assembly alignment with the second fuselage structure.

12. The system of claim 11 wherein (i) each of the first and second reflector targets includes target indicia representative of a waterline axis and a buttline axis, and (ii) the laser designator of each of the first and second transmitters utilizes the target indicia to determine proper waterline and buttline axes alignment between the first and second fuselage structures.

13. The system of claim 12 wherein the target indicia includes a crosshair indicator having reflective properties.

14. The system of claim 7 wherein the manipulator system includes a jacking system.

15. The system of claim 7 wherein the manipulator system includes a cable support system.

16. The system of claim 7 wherein the manipulator system includes a robotic system.

17. A method for moving a first fuselage structure and a second fuselage structure of an aerospace vehicle into assembly alignment, the method comprising:
coupling a first transmitter to the first fuselage structure such that the first transmitter is indexed to a first seat track of the first fuselage structure;
coupling a first reflector target to the second fuselage structure such that the first reflector target is indexed to a first seat track of the second fuselage structure and cooperates with the first
