Description

  1. TASK 70-47-00-470-501 V-band Clamps - General Information

    1. General

      1. The clamps are made of three segments, each with an internal V shape, which engage with and hold together the two mating flanges. The segments are each attached to a clamp strap, with spot welds. The clamp strap has two fork and loop shape ends, one of which holds a trunnion assembly and the other a T-bolt assembly. A 'Fail-safe' latch is located below the loop shape ends, which is a single piece tongue, spot welded to the clamp strap. A stiff-nut is used, together with the T-bolt assembly, to hold the clamp around the flanges.

      2. The clamp is a quick release device used to attach the engine bleed air system ducts together.
