Taxiing Technologies in Aerospace Engineering


Aircraft does not mean flying for all time in aerospace engineering. Seamless flying requires lots of details about engineering and operation. Each flight has a story that starts with take off and ends with landing. During flight story taxiing is one of the core piece in operations. To go from one place to another in airport it is necessary to use taxiways. When you mention it as going A to B, it seems there is no problem. However taxiing has much more detail according to mentioning details.

Flying means speed. And if you need speed you have to get high power in your engines. In aerospace engineering engines are designed to operate with ideal conditions. Ideal conditions for an aircraft means optimum flight altitude. At low power conditions engines operate lower efficiency than normal conditions. As a simple detail lower efficiency means more cost in all engineering designs not only aerospace engineering.

Why Is Taxiing Important in Aerospace Engineering

Taxiing can be seen a simple movement of aircraft before take off and after landing. However typical passenger aircraft spends nearly 4 hours during taxiing. Moreover all of these operations has nearly 600 liters of fuel consumption. Because of time and energy details taxiing is important in aerospace engineering. Beyond cost and supply common taxiing operations has great emissions, too.

New taxiing technologies can decrease fuel consumption up to 25% of 90 minutes long flight. Decreasing emissions of aircraft is one of the goals in aerospace engineering. Most of the motor and rotor technologies are based on less consumption and emission. State of art taxiing technologies can help to reach these goals.

Ground operations require great organization skills and technologies in aerospace engineering. However it is not as easy as collaborating ground services with aircraft design.

Taxiing Without Engine Power in Aerospace Engineering

Electric taxiing system technologies have similar principle to hybrid cars. New technologies in aerospace engineering can decrease fuel consumption. Low speed of aircraft is known as a new development area of operations. Electric motors that are located on wings can be used during taxi and runway movements.

Electric motors move according to WACU (Wheel Actuator Controller Unit) commands by using APU (Auxillary Power Unit) power. Electric power in taxiing speed led to have less emissions and fuel consumption.

Electric power led having less fuel consumptions during ground operations.

APU unit in wheels of aircraft. Electric power led having less fuel consumptions during ground operations.

Taxiing has own strategies and border itself. Movement strategy of aircraft has major effect on less fuel consumption. Conventional methods are important for warming up and cooling down of engines. Since 2012 major developments has recorded in new taxiing technologies. By using today’s technologies it is possible to decrease fuel consumption up to 4 percent for per flight. At the moment commercial examples are used by some airlines.

With engine technologies it is important to use operational technologies about taxiing. GPS-based ground services and parking assisted navigation systems helps aircrafts and airport for capacity utilization and fuel consumption. Beyond engineering and cost new tearing technologies has advantage of less noisy environment in aerospace engineering.
