A smooth, debris-free, nonflammable area from which rockets are fired to launch them.
Industry:Aviation
A smooth, flat, circular area around a bolt hole that provides a good seat for the bolt head or for a washer under the bolt head.
Industry:Aviation
A smooth, sharp-pointed tool used to make holes in soft materials such as leather, plastic, or wood.
Industry:Aviation
A snap-action switch that requires a very small amount of movement for its actuation. The amount of movement needed is the same each time the switch is actuated. Precision switches are used in position-indicating circuits and as limit switches to start or stop an action any time a mechanical device reaches a specific position.
Industry:Aviation
A socket into which a plug can be pushed to make an electrical connection. Jacks are often used on the front of electrical test equipment to make temporary connections for test leads. Some of the more commonly used types of jacks are phone jacks, miniature jacks, microphone jacks, and banana plug jacks.
Industry:Aviation
A socket wrench with a double hex, or a 12-point, opening broached into its open end. A 12-point socket is easier to position on a nut or bolt head than a six-point socket.
Industry:Aviation
A soft, black form of carbon that normally has a greasy feel. Graphite, also known as black lead, is used as a dry lubricant and also as the “lead” in a pencil. Structural graphite is used in composite structure because of its strength and stiffness.
Industry:Aviation
A soft, bluish-white, malleable, highly toxic, metallic chemical element. Thallium’s symbol is Tl, its atomic number is 81, and its atomic weight is 204.37. Thallium is used in the manufacture of photocells and infrared detection devices and in poison for rodents.
Industry:Aviation
A soft, bright, silvery, rare-earth, metallic chemical element. Ytterbium’s symbol is Yb, its atomic number is 70, and its atomic weight is 173.04. Ytterbium is used as an X-ray source and in the study of superconductivity.
Industry:Aviation
A soft, brown, nonmetallic, trivalent chemical element. Boron’s symbol is B, its atomic number is 5, and its atomic weight is 10.811.
Boron is used to add stiffness and strength to some of the modern composite structural materials, and to dope silicon or germanium to make a P-type semiconductor material.
