Patent ID: 7681836

Claim:
An aircraft system comprising: a detection device connected to an aircraft and configured to detect atmospheric disturbances in the path of the aircraft, the connection between the detection device and the aircraft being disposed between a nose of the aircraft and landing gear of the aircraft; a structure box configured to resist pressurization forces while the aircraft is in flight and to separate the pressurized zone from the detection device, said structure box covering the detection device and located in the pressurized zone external and adjacent to the aircraft; and an aerodynamic fairing, which is a component distinct from the structure box, that covers the structure box with respect to an environment external to the aircraft, wherein the detection device is an “L” shaped light imaging detection and ranging (lidar) device, a vertical part of the L shape being located inside the aircraft, and a horizontal part of the L shape being located outside the aircraft and inside the structure box, wherein the structure box includes a flat glass portion on a front part of the structure box with respect to a longitudinal axis of the aircraft extending from the nose of the aircraft rearward, and wherein the structure box is a caisson.
