Industry:Aviation
A shock wave which forms when an aircraft is flying at a speed faster than the speed of sound, a speed greater than Mach one. A bow wave either forms immediately ahead of the aircraft or is attached to the nose of the aircraft.
Industry:Aviation
A shock-absorbing coupling used between the accessory drive in an engine and an accessory that is subject to torsional vibrations.
A safety link designed to shear if the accessory should freeze, or jam, is usually incorporated as a part of a drive coupling.
Industry:Aviation
A shop tool used to test spark plugs after they have been cleaned and gapped.
After a spark plug has been serviced, it is screwed into the bomb tester, and about 200-psi air pressure is applied to the firing end. High voltage is directed into the terminal cavity of the spark plug, and the electrodes are observed to see the type and amount of spark being produced.
If a spark plug operates properly in a bomb tester, it will almost always work properly when it is installed in an aircraft engine.

Industry:Aviation
A short, high-strength, polished steel pin that connects a link rod in a radial engine to the master rod. A radial engine has only one throw on the crankshaft for each row of cylinders. Only one connecting rod (the master rod) goes around the throw of the crankshaft and connects one piston to the crankshaft.
The pistons in the other cylinders are connected to the master rod by link rods (articulated rods), and the link rods are connected to the master rod with knuckle pins.
