canard configuration. 14 CFR Part 1: “A configuration in which the span of the forward wing is substantially less than that of the main wing.” candela. A measurement of luminous intensity in the International System of measurements. The candela is also known as the new candle, or the international candle. candlepower. A measure of light intensity. One candlepower is the amount of light intensity produced by one international candle or one candela. cannibalize. To take serviceable components from one unit and use them on another. Military and industrial surplus equipment is often used as a source of components that can be obtained by cannibalizing the equipment. canopy (aircraft structure). The transparent enclosure that covers an aircraft cockpit. Most modern canopies are formed in the shape of a bubble from a single piece of transparent plastic material. canopy (parachute). The fabric body of a parachute. can tap valve. A valve attached to a sealed can of liquid refrigerant that controls the flow of refrigerant into an aircraft vapor-cycle cooling system. When the valve is securely attached, a seal on the can is pierced, allowing the refrigerant to flow. canted bulkhead. The wall of a compartment in an aircraft that, because of structural reasons, is not straight up and down. A canted bulkhead angles upward from the deck. canted rate gyro. A rate gyro whose gimbal axis is tilted so it can sense rotation of the aircraft about its roll axis as well as its yaw axis. cantilever beam. A beam with all of its support inside the beam itself. It uses no external struts, braces, or wires. A diving board is an example of a cantilever beam. cantilever wing. A wing with no external bracing — all of the strength of the wing is inside its structure. The wing spars are built in such a way that they carry all the bending and torsional loads. can-type combustor (gas turbine engine component). A combustor, or burner section of a gas turbine engine made up of several individual burner cans. These cans are long cylinders of thin sheet metal consisting of an outer housing and an inner liner, arranged axially around the power shaft of the engine, more or less parallel to it. Discharge air from the compressor flows through the cans where fuel is sprayed into it and burned to add energy. Cooling air flows between the housing and inner liner, and through holes in the inner liner to keep the temperature of the cans low enough that they will not be damaged. Can-type combustors were used on some of the early turbojet engines, but most modern engines use the more efficient annular, or can-annular combustors. canvas. A heavy, tightly woven cloth made of cotton. capacitance (electrical quantity). The amount of electrical charge that can be stored in a capacitor under a given amount of electrical pressure (voltage). The formula for capacitance is C = Q ÷ E, in which C is the capacitance in farads, Q is the quantity (amount) of charge in coulombs, and E is the electrical pressure, in volts. Capacitance is measured in farads, microfarads, or picofarads. |
