Navy documents list the use of asbestos cloth in the main boilers of these ships and the use of woven asbestos material in flanged casing panels. 737 MAX is built with the new CFM LEAP-1B engine. In order to keep a new aeroderivative product’s overall cost as low as possible, the aircraft engine cho-sen as the basis for this line must be convertible The metal casing or shell is a hexagon-shaped shell with threads, which allow the spark plug to be installed into a tapped socket in the engine cylinder head. The last point is extremely important. Thrust forces generated by gas path momentum flow changes in a jet engine are transmitted by pressure (and friction) forces on stators and struts attached to the engine case. and propels the aircraft forward, this is called bypass air and provides 75% of the engine’s thrust The rest (about a phone box’s worth) of the air goes through the engine compressor which squeezes it to one-fiftieth of its volume (about a shoe box). One unique feature is the fact that there is no need to cut that case! A pilot purchases an aircraft with a high time engine. The brand new engine in a brand new aircraft started making tons of metal at about 700 hours and 4 years. As with the main combustor in a gas turbine, the afterburner has both a case and a liner, serving the same purpose as their main combustor counterparts. Then you have the case, which is more than likely made of an aluminum alloy. So it is made by high grade cast iron. The bottom line: only use those sealant materials approved by the Lycoming Overhaul manual and other service publications, and only use them for approved purposes.
