Directional control valve Directional control valve. Directional control valves are one of the most fundamental parts in hydraulic machinery as well as pneumatic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a spool inside a cylinder which is mechanically or electrically controlled.

Flight control surfaces Flight control surfaces. (Redirected from Lateral axis) Basic aircraft control surfaces and motion. Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. Development of an effective set of flight control surfaces was a critical advance in the development of aircraft. Early efforts at fixed-wing aircraft design succeeded in generating sufficient lift to get the aircraft off the ground, but once aloft, the aircraft proved uncontrollable, often with disastrous results.

Field-Oriented Control of Small DC Motors put Drones on a Rising Flight Path FOC is one of the most commonly used methods for vector control. It works by managing stator windings to keep the flux produced by a rotor’s permanent magnets orthogonal to the stator field. FOC was originally developed to control three-phase AC motors.

Engineering Essentials: Directional-Control Valves Even more basic than the discrete directional-control valve is the digital valve. As in digital electronics, digital valves operate either on or off. Whereas discrete valves generally use a spool to achieve two, three, or more positions, discrete valves use a plunger, poppet, or ball that seals against a seat.

Coaxial Couplers Directional couplers are used in a wide variety of applications to sample incident and reflected microwave power without disturbing the transmission line. Applications for directional couplers include line monitoring, measuring power and load source isolators. Coax directional couplers can be used for sample power from a line without altering the characteristics of the line. Power measurements are achieved by inserting a directional couple and using simple, low level detectors or field strength meters and power measuring equipment.

Air traffic control Air traffic control is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. In some countries, ATC plays a security or defensive role, or is operated by the military. To prevent collisions,

Directional boring A directional boring unit in action. Directional boring, commonly called horizontal directional drilling or HDD, is a steerable trenchless method of installing underground pipe, conduit, or cable in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area.

Flight controls: How an airplane is controlled. Primary flight controls. Airplane control systems are carefully designed to provide a natural feel, and at the same time, allow adequate responsiveness to control inputs. At low airspeeds, the controls usually feel soft and sluggish, and the airplane responds slowly to control applications.

Flight controls: How an airplane is controlled. The rudder controls movement of the airplane about its vertical axis. This motion is called yaw. Like the other primary control surfaces, the rudder is a movable surface hinged to a fixed surface, in this case, to the vertical stabilizer, or fin. Moving the left or right rudder pedal controls the rudder.

How was Saul changed to Paul? Answer. He didn't. Many mistakenly assume the Lord changed Saul's name to Paul sometime after Saul converted from Judaism to Christianity, which happened during his encounter with Christ on the Road to Damascus (Acts 9:1-19). Unlike the instance of Jesus changing Simon's name to Kepha (Gk.

Power dividers and directional couplers Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit. An essential feature of directional couplers is that they only couple power flowing in one direction.
