A type of gas turbine engine compressor which has both an axial-flow and a centrifugal stage. Inlet air first passes through the low-pressure axial-flow compressor and then flows into the high-pressure centrifugal compressor. The centrifugal compressor builds up the pressure of the air high enough for efficient operation in the combustors.

A type of gas turbine engine that has a set of lengthened blades on the low-pressure compressor or low-pressure turbine. Air moved by these special blades bypasses the core engine and produces between 30% and 75% of the total thrust produced by the engine.
Industry:Aviation
A type of glass made from pure quartz. Quartz glass does not filter out ultraviolet rays.
Industry:Aviation
A type of glass that does not leave jagged fragments when it breaks. Safety glass may be made by laminating a layer of resilient transparent plastic material between two sheets of glass. This type of safety glass will break, but all of the pieces stick to and are held by the center plastic layer. Another form of safety glass is tempered glass that breaks into small grains, rather than into sharp pieces.
Industry:Aviation
A type of glow lamp made of two insulated electrodes inside a glass envelope filled with neon gas. Neon gas does not conduct electricity until the voltage across the electrodes rises to the ionization, or firing, voltage of the neon. When this voltage is reached, the neon gas ionizes and conducts.
Electrons flowing through the ionized gas cause it to glow with a reddish-orange light. The gas continues to glow until the voltage across the electrodes drops to a value lower than its ionization voltage.
Industry:Aviation
A type of graph used to show the way values change. The horizontal axis of the graph represents time, and the vertical axis represents the changing value. Straight lines are used to connect points that show the values at each plotted time.
Industry:Aviation
A type of hammer whose head has the shape of a cylinder. Mallet heads are usually made of a soft material such as wood, plastic, fiber, leather, or a soft metal, such as brass or lead.
Industry:Aviation
A type of hand stitch used to join two pieces of fabric that butt together, but do not overlap. Baseball stitches are used to sew together the edges of a tear in the fabric used to cover an aircraft structure. The baseball stitch gets its name from this type of stitch being used to sew the cover on a baseball.
Industry:Aviation
A type of hand-held fire extinguisher which uses a dry chemical, such as sodium bicarbonate, as the extinguishing agent. The dry chemical is normally forced out of the extinguisher by compressed nitrogen.
Industry:Aviation
A type of hand-held hammer used for forming sheet metal. One end of the head is round and has a flat face. The other end is wedge-shaped, with the apex (peak) of the wedge parallel to the handle. A cross peen hammer is much like a straight peen hammer except the wedge on its head is perpendicular to the handle.
