By Isha Jaiswal Aircraft engine manufacturers all over the world have become environmentally conscious and are striving to increase passenger comfort while enhancing the fuel efficiency of aero engines. They have started utilising blended materials including alloys and polymers to make lighter, cheaper but more powerful aero engines. Aeronautical engineers are also using ingenious technologies that have never been tried so far such as the introduction of gearboxes within the engines, use of 5G technologies linked to sensors and crunching the aircraft generated big data with artificial intelligence on a real-time basis so as to enhance fuel efficiency, reduce noise, increase the Mean Time Between Failure (MTBF) and bring in greater passenger comfort. It is worth having a look at the latest developments taking place in the field of aeronautical engineering.

GEARBOX MOUNTED ENGINES The world renowned company Pratt & Whitney toiled for less than two decades and has produced a brilliant technological feat named the Pratt & Whitney GTF engine series wherein they have introduced a gearbox that connects with the fan in the front of the engine to the turbine at its rear. Due to the gearbox, these rotors are able to spin at different speeds with the gearbox offering a 1:3 ratio. What this means is that if the fan in the front turns one revolution in a given time, then, with the gearbox having been interfaced in between the turbine located at the other end will revolve three times within the same span of time as was taken by the fan in front. This implies that at whatever speed the front fan spins, the rear turbine of the engine will spin at three times
