DARCHEM Engineering has delivered the first set of thrust-reverser insulation blankets for Boeing's next-generation 737-700. The blankets were manufactured, in accordance with CATIA computer-aided-design data, sent to the UK company by Boeing.

A suite of 15 "master" models, assembly jigs, press tools and inspection fixtures were then cast and machined.

The blankets are designed to protect the inner components of the composite thrust reverser from the heat radiating from the 737-700's CFM International CFM56-7 engines. The insulation consists of lightweight MIN-K material coated in rigidised stainless-steel foils.

"This corrosion-resistant design is now proving more popular with Boeing than traditional spray-on intumescent insulation material," says Ken Oliver, Darchem sales and marketing director.
