Mobile aircraft inspection system
View Patent ↗A system for scanning aircraft for concealed threats is provided. The system comprises a vehicle and a manipulator arm attached with a scanning head that can be maneuvered in multiple directions to completely scan an aircraft from the outside. The system uses transmission based X-ray detection, backscatter based X-ray detection or a combination thereof, in various embodiments. The system also includes gamma-ray and neutron detectors, for detection of nuclear and radioactive materials.
1. A system for externally scanning an aircraft, having a body and an underside, to detect concealed threats, the system comprising:
a mobile gantry defined by two vertical beams connected by a horizontal beam, wherein the horizontal beam comprises a top side of said gantry, and wherein said gantry is capable of being moved along the length of the aircraft being scanned;
an X-ray source connected to the top side of said gantry, said source capable of being moved horizontally along the top side; and
a movable detector unit comprising a first set of detectors, said detector unit being aligned with said X-ray source and being positioned along the underside of the aircraft, such that the first set of detectors receive X-rays transmitted through the aircraft from said X-ray source.
2. The system of claim 1 , wherein the positions of said X-ray source and said first set of detectors are synchronized remotely.
3. The system of claim 1 , wherein the scanning motion comprises moving the mobile gantry along the length of the aircraft and moving the X-ray source along the width of the aircraft.
4. The system of claim 1 further comprising a second set of detectors disposed on the top side of said gantry for receiving the X-rays scattered back from the aircraft.
5. The system of claim 1 , wherein said X-ray source is capable of being tilted in at least four directions.
6. The system of claim 1 , wherein the detected threats include organic materials, inorganic materials and nuclear materials.
7. A system for externally scanning an aircraft, having a body and an underside, to detect concealed threats, the system comprising:
a mobile gantry defined by two vertical beams connected by a horizontal beam, wherein the horizontal beam comprises a top side of said gantry, and wherein said gantry is adapted to move over at least one section of the aircraft being scanned;
a transverse beam, having a first end and a second end, coupled to the top side of said gantry, adapted to be moved horizontally along the said top side, wherein an X-ray source is connected to the first end of said transverse beam and a counterweight is connected to the second end of said transverse beam to balance said X-ray source; and
a movable detector unit comprising a first set of detectors, said detector unit being aligned to the X-ray source, such that the first set of detectors receive X-rays transmitted through the aircraft from said X-ray source.
8. The system of claim 7 further comprising a second set of detectors disposed along with the X-ray source for receiving the X-rays scattered back from the aircraft.
9. The system of claim 7 , wherein said X-ray source is capable of being tilted in four directions.
10. The system of claim 7 , wherein positions of said X-ray source and said first set of detectors are synchronized remotely.
11. The system of claim 7 , wherein the detected threats include organic materials, inorganic materials and nuclear materials.
