When establishing the circuitry of a system, there are many ways in which wires can be connected to one another. While line splicing often serves as a simplistic method, it has the chance of creating an unsafe connection that may not be able to be repaired or replaced easily. Furthermore, splicing is not optimal when there is a need to connect multiple wires together or create a series of localized connections. In such cases, a terminal block is most often used. Consisting of a simple modular block with clamping mechanisms and conducting strips, such components can allow for the connection of multiple wires in an efficient and organized fashion.

What is an Actautor?

An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, like opening a valve. To carry this out, an actuator requires a signal and energy source. The control signal is relatively low energy and its source could be electric voltage or current, pneumatic pressure, hydraulic pressure, or human power. The actuator receives this control signal and responds, turning the signal’s energy into mechanical motion. There are five common actuators types: hydraulic, pneumatic, electrical, thermal, and mechanical. This blog will explain each configuration and what makes them unique.

When a GPS system’s service is interrupted, an aircraft’s Inertial Navigation System (INS) is there to save the day. This self-contained flight management system provides aircraft locale without the need for input radio signals from ground navigation facilities or transmitters. The location of an aircraft is continuously updated through calculations based on the forces experienced (altitude, velocity, direction, accelerations) by INS accelerometers. An interface control head is used to input a starting location and from there any movement force data recorded by an accelerometer is then used to calculate an aircraft’s location based on that starting point.  A minimum of two accelerometers are used, one referenced to the north and one referenced to the east. In older units (due to gravity), accelerometers are mounted onto a gyro-stabilized platform that averts the introduction of error. An accumulated error of less than one mile after one hour of flight is possible.

When readying aircraft for flight, one of the most important procedures is bringing the aircraft to a position on the taxiway for clearance. This procedure is often conducted by using pushbacks, or tugs, which are low profile vehicles that can move around aircraft to a desired position. This can be done to bring aircraft out of a hanger, or away from an airport gate. While many aircraft hold the ability to do this operation themselves, there are many possible risks as the aircraft would need to use reverse thrust, possibly causing damage to buildings, equipment, and more. As this method is not practical, utilizing tugs is highly beneficial for preparing aircraft for flight.
