- Company Profile:
Severe damage to moving parts caused when one metal part moves across another without sufficient lubricant between them. Enough heat is generated by friction to cause the high points of the surfaces to weld together; continued movement tears, or scuffs, the metal.
Industry:Aviation
Small-diameter metal tubes that connect cantype combustors in a turbine engine to carry the ignition flame to all of the combustion chambers. The British call combustion liners flame tubes.
Industry:Aviation
Specification of each gas turbine engine determined in the manufacturer’s test cell when the engine was calibrated. This data includes the engine serial number with the EPR that produced a specific RPM. The technician refers to this information when trimming the engine.
Industry:Aviation
Spool-shaped sheet metal plugs installed in the hollow throws of some engine crankshafts.
Industry:Aviation
Spring-loaded doors in the inlet duct of some turbojet or turbofan engine installations that are opened by differential air pressure when inlet air pressure drops below that of the ambient air. Air flowing through the doors adds to the normal inlet air passing through the engine and helps prevent compressor stall.
Industry:Aviation
Supersonic combustion ramjet. A special type of ramjet engine whose fuel can be ignited while the vehicle is mobbing at a supersonic speed.
Industry:Aviation
The ability of an aircraft engine to perform its designed functions under widely varying operating conditions.
Industry:Aviation
The absolute pressure of air at the inlet to the fuel metering system of a turbocharged engine. Upper-deck pressure is the same as the turbocharger discharge pressure.
Industry:Aviation
The absolute pressure of the air inside the induction system of a reciprocating engine.
Industry:Aviation
The absolute pressure that exists within the induction system of a reciprocating engine. It is the MAP that forces air into the cylinders of the engine. MAP is commonly called manifold pressure.
