Aeronautics
staggered timing
Aviation; Aeronautics
A method of timing the dual ignition of a reciprocating engine. When the timing is staggered, the spark plug nearest the exhaust valve fires before the spark plug nearest the intake valve. In some ...
continuous wave radio transmission (CW)
Aviation; Aeronautics
A method of transmitting radio-frequency electromagnetic energy in the form of long and short spurts that may be considered to be dashes and dots. The electromagnetic energy radiates from a ...
vulcanize
Aviation; Aeronautics
A method of treating crude rubber with heat to give it such useful properties as elasticity, strength, and chemical and dimensional stability.
oil dilution
Aviation; Aeronautics
A method of treating the lubricating oil to make it possible to start a reciprocating engine when the temperature is very low. When the oil gets cold, it becomes thick and hard to move, making it ...
porous chrome plating
Aviation; Aeronautics
A method of treating the walls of aircraft reciprocating engine cylinders that hardens them and increases their ability to hold lubricants. Worn cylinder barrels may be ground so their bore is ...
impedance coupling
Aviation; Aeronautics
A method of using a transformer to join, or couple, stages of an electronic device, such as an amplifier. The impedance of the primary winding of the coupling transformer is the same as the output ...
cross-hatching
Aviation; Aeronautics
A method of using angled, parallel lines to show that a section of a drawing has been cut away. Different arrangements of the cross-hatch lines are used to identify the material of which the part is ...
