Feature: Avionics
DC motors for luxury, safety and
zero-emission targets in avionics By Dave Walsha, Sales Manager, EMS

espite being hit hard by the pandemic, the aviation industry is finally beginning to recover. According to consultancy firm Bain & Company, by the end of this
year, global demand for flights will reach 84% of 2019 levels, the year before the pandemic struck. Tere is a growing demand for flights on private jets, too; in 2019 there were some 22,000 private jets registered around the world, expected to grow by a further 7,300 by 2030. And, whilst customers expect increased
comfort and entertainment on their flights, the aviation industry must also address its emissions.

aircraſt, not least to provide comfort at the push of a button, such as seat adjustment and reclining. In private and business jets, tables, smart device holders, computers, TV screens, etc, are also raised and lowered at the push of a button. Mechanisation of many features, including window blinds, partition walls and armrests, is becoming more common, which means demand for motors on board aircraſt will only continue to grow. And motors are also used to adjust the valves that regulate pressure in the aircraſt’s air-conditioning system. Also, for many people surfing the
Internet whilst flying is essential, so communication antennas must continuously and automatically adjust to provide the best satellite signal, which is also enabled by motors. Ten there’s safety: Electric motors on
aircraſt are vital in safety-critical applications, such as in the locking mechanisms on aeroplanes for cabin doors, emergency exits and the pilots’ seats, which must remain in a fixed position during take-off and landing. When a plane descends for landing, the landing gear is extended. To ensure it remains in place and landing is successful, a motor gearhead operates a locking pin.
Weight reduction In 2019, aviation accounted for 2.5% of the world’s carbon dioxide emissions, equating to nearly 1000 million annual metric tonnes, a 29% increase over 2013 levels. Tis indicates that the aviation industry must act now to reduce its emissions and play its part in the drive towards net zero. Air travel is expected to surpass pre-
pandemic levels, so reducing the number of
