The constant-pressure cycle of energy release used to describe the action of a gas turbine engine. Fuel is added to the air passing through the engine and is burned. Heat from the burning fuel-air mixture expands the air, and since this air is not confined, it accelerates as it moves through the engine.
The Brayton cycle, a constant-pressure cycle, is an open cycle because all the events, compression, combustion, expansion, and exhaust take place at the same time, but in different locations within the engine.
The Brayton cycle differs from the Otto cycle used in reciprocating engines because the Otto cycle is a constant-volume cycle.
Industry:Aviation
The constant-volume cycle of energy transformation used in a reciprocating engine. Fuel and air are drawn into the cylinder as the piston moves to the bottom of its stroke. The fuel-air mixture is then compressed as the piston moves upward in the cylinder, and when the piston is near the top of its stroke, the mixture is ignited and burns. The burning mixture heats and expands the air inside the cylinder and forces the piston down, performing useful work. The piston then moves back up, forcing the burned gases out of the cylinder. The pressure inside the cylinder varies throughout the cycle, but all events take place in the same location.
“Out” (air traffic control). A term used in air traffic control to indicate that the conversation is ended and no response is expected.
Industry:Aviation
The continuation of the spark across the gap in a shielded spark plug after the fuel-air mixture in the cylinder is ignited.
Capacitance afterfiring is caused by the return of electrical energy stored in the capacitance of the shielded ignition leads. Capacitance afterfiring is eliminated by installing a resistor inside the spark plug.
Industry:Aviation
The control column in an airplane on which the control wheel is mounted. Back-and-forth movement of the yoke moves the elevators, and rotation of the control wheel moves the ailerons.
Industry:Aviation
The control for a cathode-ray tube that regulates the quantity of electrons in the beam that strikes the phosphorescent screen inside the cathode-ray tube. The intensity of the electron beam determines the amount of light produced by the screen.
Industry:Aviation
The control in a helicopter that allows the pilot to change the pitch of the rotor blades individually, at a specific point in their rotation.
The cyclic pitch control allows the pilot to tilt the plane of rotation of the rotor blades to change the direction in which the lift produced by the rotor disk acts. Tilting the plane of the rotor controls the direction the helicopter moves.
Industry:Aviation
The control in an aircraft that regulates the power or thrust the pilot wants the engine to develop.
Industry:Aviation
The control in the cockpit of an airplane on which the control wheel is mounted. Rotation of the control wheel operates the ailerons, and back-and-forth movement of the control column moves the elevators up or down.
Industry:Aviation
The control of aircraft traffic from the ground. Air traffic control is done from control towers whose personnel direct air traffic in the vicinity of an airport and air route traffic control centers whose personnel direct air traffic along the airways between airports.
Effective air traffic control is possible because of efficient two-way radio communications and radar that allow controllers to keep track of all the aircraft they are controlling.
Industry:Aviation
The controller providing information and final approach guidance during precision approach radar (PAR) and airport surveillance radar (ASR) approaches utilizing radar equipment.
