Under the agreement, Strata will replicate the capabilities of the Boeing Salt Lake City 787 vertical fin assembly line to sub-assemble vertical fins for the Dreamliner family of airplanes from its Al Ain facility.
Eighty fins were inserted on each side of the heat pipe fin assembly with a pitch of 3.7 mm (0.146 in.) as shown in Figure 5b.
Upon inspection he identified one of four bolts missing used to attach the tail fin assembly to the missile body.
Last June, Boeing commemorated the opening of its new composite vertical fin assembly line at its production facility in Salt Lake City.

The circular air cooling fin assembly (Fig 5), consisting of fins (29) and spacing rings (30) is attached by swaging the thickened portion of the fins (29a) to the barrel, ...
The vertical fin assembly is an elliptical airfoil comprised of the leading edge, center box, trailing edge, and rudder which, together, function as flight control surfaces that maintain yaw, or side-to-side horizontal movement of an airplane in flight.
The unit retains the body and fin assembly for future use with the M880/M766 refurbishment kits.
In addition, based on its competitiveness and performance, Strata is positioned to become a future supplier of the 787 vertical fin assembly. "Boeing now wishes to elevate Mubadala into a tier one supplier means that they stand a great chance of producing composite structures for the 787-10X, 777-8X and 777-9X -- all three are new airplanes that customers like Etihad Airways and Emirates are keen to be involved with an order," Saj Ahmad, chief analyst at London-based StrategicAero Research, told Khaleej Times.
Even a microscopic film of air would reduce the conductivity of the cooling fin assembly by a few orders of magnitude.
The 11-1-38 positioning procedures did not allow for the munitions to be safely assembled on the MHU-226 because the chocks obstructed the installation of the BSG-92 fin assembly. The technical order's current procedures for positioning and tying down the munitions did not allow for the proper unloading from the MHU-226 munitions trailer preventing safe installation onto the aircraft.
The T-blocks were machined to nearly the same depth as the fin sample assembly and provided one-dimensional uniform conduction heat flux in the y-direction (as shown in Figure 2) perpendicular to the fin assembly walls.
