The highest peak value of reverse voltage a rectifying diode can withstand before it breaks down and conducts. A semiconductor diode does not normally conduct when it is reverse-biased (the anode negative and the cathode positive). But if too high a reverse voltage is placed across the diode, it will break down and conduct.
Industry:Aviation
The highest point of an airport’s usable runways measured in feet above mean sea level.
Industry:Aviation
The highest pressure of the fuel-air mixture inside the cylinder of a reciprocating engine that allows the mixture to burn evenly, rather than explode, or detonate.
Industry:Aviation
The high-strength carbon-steel wire bundles that give an aircraft tire its strength and stiffness where it mounts on the wheel.
Industry:Aviation
The high-strength steel component in an airplane propeller that attaches to the propeller shaft of the engine and supports the propeller blades. The spider and the roots of the blades are enclosed in the high-strength propeller hub.
Industry:Aviation
The high-strength steel tube in which the piston moves up and down in a reciprocating engine. The cylinder barrel of an air-cooled engine has fins cut onto its outer surface to remove heat, and it screws into the cylinder head to form the cylinder assembly.
Industry:Aviation
The high-velocity stream of turbulent air behind an operating aircraft engine.
Industry:Aviation
The hinge at the root of a helicopter rotor blade that allows the tip of the blade to move back and forth in its plane of rotation. The axis of the alpha hinge is perpendicular to the plane of rotor rotation. An alpha hinge is also called a lead-lag hinge.
Industry:Aviation
The hinge in the root of a helicopter rotor blade that allows the blade tip to move back and forth in its plane of rotation. Movement about the lead-lag hinge is called drag, and this movement is opposed by drag dampers. A lead-lag hinge is also called an alpha hinge.
Industry:Aviation
The hinge with its axis parallel to the rotor plane of rotation.
The flapping hinge permits the rotor blades to flap up or down to equalize the lift, or rotor thrust, between the advancing-blade half and the retreating-blade half of the rotor disk.
