Abstract

Sensor pod attachment assemblies are provided for attaching a sensor pod containing airborne sensor equipment to an aircraft fuselage. The sensor pod assemblies may include fore and aft pairs of attachment pylon assemblies each having a lower end attached to the aircraft fuselage and an upper end attached to the sensor pod. The fore pair of attachment pylon assemblies can include port and starboard pylon structures, and a cross-support base connected to upper ends of the port and starboard pylon structures. The aft pair of attachment pylon assemblies may include a lengthwise adjustable spar assembly.

Claims

1. A sensor pod attachment assembly for attaching a sensor pod containing airborne sensor equipment to an aircraft fuselage, the attachment assembly comprising:

fore and aft pairs of attachment pylon assemblies each having a lower end attached to the aircraft fuselage and an upper end attached to the sensor pod, wherein

the fore pair of attachment pylon assemblies includes port and starboard pylon structures, and a cross-support base connected to upper ends of the port and starboard pylon structures, and wherein

each of the port and starboard pylon structures includes (i) elongate fore and aft upright spars having lower ends for attachment to the aircraft fuselage and upper ends connected to the cross-support base, and (ii) ribs and stringers connecting the fore and aft upright spars to one another, and wherein

the cross-support base includes port and starboard lug mounts positioned above an upper end of the port and starboard pylon structures, respectively, for attaching the sensor pod to the fore pair of attachment pylon assemblies.

2. An aircraft which comprises the sensor pod attachment assembly as in claim 1.

3. The sensor pod attachment assembly as in claim 2, wherein each of the upper and lower connector rods are threadably connected to the upper and lower attachment fittings, respectively.

4. The sensor pod attachment assembly as in claim 3, wherein the upper and lower connector rods are eye-bolt rod connectors.

5. The sensor pod attachment assembly as in claim 2, wherein the lengthwise adjustable spar assembly further includes an adjustment nut threadably connected to the at least connector rod for positionally locking the at least one connector rod.

6. The sensor pod attachment assembly as in claim 3, wherein the lengthwise adjustable spar assembly further includes upper and lower adjustment nuts associated with the upper and lower connector rods for positionally locking the upper and lower connector rods relative to the upper and lower attachment fittings, respectively.

7. The sensor pod attachment assembly as in claim 2, wherein the at least one attachment pylon further comprises pod and fuselage attachment lugs for respectively attaching the upper and lower connector rods to the sensor pod and aircraft fuselage, respectively.

8. The sensor pod attachment assembly as in claim 7, wherein the fuselage attachment lug comprises a U-shaped channel member defining a coaxially aligned pair of apertures, wherein the lower connector rod is an eye-bolt connector rod aligned with the apertures of the channel member, and wherein the assembly comprises a connector pin inserted through the apertures and the connector rod to attach the connector rod to the U-shaped channel member.

9. The sensor pod attachment assembly as in claim 8, wherein the fuselage attachment lug comprises a pair of lateral fitting members connected to the U-shaped channel member.

10. The sensor pod attachment assembly as in claim 1, wherein the fore and aft pairs of attachment pylons each include forward and rearward airfoils extending forwardly and rearwardly therefrom relative to the aircraft fuselage.

11. An aircraft which comprises the sensor pod attachment assembly as in claim 1.
